Winter Plant Care at a Glance

Short on time? Here are the most important things to remember this winter.

✔ Water only when the soil is dry, not on a set schedule.

✔ Move your plants closer to bright, indirect light.

✔ Pause fertilising until you see fresh spring growth.

✔ Keep plants away from heaters, fireplaces and cold drafts.

✔ Wipe leaves regularly to maximise the available winter light.

✔ Wait until spring to repot unless it's absolutely necessary.

✔ Remember that slower growth is completely normal.

Winter Indoor Plant Care Guide

As the days grow shorter and temperatures begin to drop, you may notice changes in your indoor plants. Growth slows, the soil stays damp for longer, and plants that were producing new leaves every few weeks suddenly seem to pause. Every winter, I receive messages from people convinced they're doing something wrong: “My Monstera has stopped growing,” “My Peace Lily doesn't look happy,” or “I think I'm killing my plant.”

The reassuring news is that, in most cases, your plant isn't struggling at all. It's simply responding to winter, exactly as nature intended. Understanding these seasonal changes is one of the biggest steps towards becoming a confident plant owner, and once you know what to look for, winter often becomes one of the easiest seasons to care for your indoor plants.

 

One of the biggest misconceptions about winter plant care is that something must be wrong if your plant isn't producing new leaves. In reality, slower growth is one of the healthiest and most natural responses your plant can have. Most popular indoor plants originate from tropical and subtropical regions where daylight hours remain relatively consistent throughout the year, but even inside our homes they continue responding to seasonal changes.

During winter, daylight hours become shorter, the sun sits lower in the sky and light intensity decreases. With less light available, plants produce less energy through photosynthesis, naturally slowing their metabolism and reducing their need for water, nutrients and intervention.

This is why the watering routine that worked perfectly during summer can quickly lead to overwatering during winter. The important thing to remember is this: slower growth doesn't mean your plant is unhealthy; it simply means it's conserving energy until longer, brighter days return.

🌿 Carol's Golden Rule: Rest is part of growing.

Plants don't need to be growing every day of the year to be healthy. Winter is simply their season to pause, conserve energy and prepare for the burst of growth that arrives with spring.

 

Winter Across Australia

One of the biggest challenges with indoor plant advice is that much of it comes from overseas. A winter in Canada is very different from a winter in Cairns, and even within Australia, the seasons vary dramatically from one region to another. That's why there isn't a single winter plant care routine that works for everyone.

Instead of following a fixed schedule, it's far more important to understand how your local climate influences light, temperature and how quickly your potting mix dries.

Tropical North Queensland

Winter is generally warm and humid, with many indoor plants continuing to grow throughout the season.

You may only need to reduce watering slightly, but it's still worth checking the soil before reaching for the watering can.

South East Queensland & Northern New South Wales

While winters are relatively mild, the shorter days mean most indoor plants naturally slow their growth.

Reduce watering, make the most of bright natural light and avoid over-fertilising until spring.

Sydney & Perth

Although winter temperatures are generally moderate, lower light levels still affect plant growth.

Allow the soil to dry a little further between waterings and consider moving plants closer to bright windows during the cooler months.

Melbourne, Adelaide, Canberra & Tasmania

In Australia's cooler southern regions, winter has a much greater impact on indoor plants.

Growth slows significantly, potting mix stays damp for longer and homes are often heated, reducing humidity around tropical plants.

This is where overwatering becomes the biggest risk.

If you live in these regions, patience is one of the best things you can offer your plants.

Let Your Home Be Your Guide

No two homes are exactly the same. A bright apartment in Brisbane may receive more winter sunlight than a shaded home in Sydney, while a well-insulated house in Melbourne will create different growing conditions to an older Queenslander with plenty of airflow. Rather than following someone else's schedule, take a few moments each week to observe your own plants.

Notice how quickly the soil dries, watch how the light moves through your home, and pay attention to new growth, leaf colour and overall health. The more you observe, the more confident you'll become.

🌿 Carol's Golden Rule: Learn your home before you learn your plants.

Every home creates its own growing environment. Once you understand how the seasons affect your space, caring for your indoor plants becomes much simpler.

 

Water Less, Observe More

If there's one piece of advice I'd love you to remember this winter, it's this:

🌿 Carol's Golden Rule: Trust the soil, not the calendar.

Overwatering is the number one reason indoor plants struggle during winter. Every year, I speak to people who are convinced they're not watering enough, when in reality, they're watering far too often. After teaching hundreds of Australians through our workshops, I've noticed that winter rarely harms indoor plants; more often, it's our kindness that gets them into trouble.

We water because we care, fertilise because we want to help, and move our plants from room to room searching for the perfect position. But winter asks us to do something different: slow down. Sometimes the kindest thing we can do for our plants is simply leave them alone.

Why Plants Need Less Water in Winter

During winter, shorter days and lower light levels mean your plants produce less energy through photosynthesis. With less energy available, growth naturally slows, and a slower-growing plant uses less water because it's producing fewer leaves, fewer roots and less overall growth.

At the same time, cooler temperatures mean water evaporates more slowly from the potting mix. The result is that soil stays moist for much longer than it does during spring and summer. If you continue watering on your usual schedule, the roots can remain constantly wet, reducing oxygen in the potting mix and creating the perfect conditions for root rot.

Understanding why your plant needs less water makes it much easier to know when to water.

How to Tell if Your Plant Needs Water

Instead of watering every seven days or every fortnight, take a few moments to check your plant first. Insert your finger about 3 to 5 centimetres into the potting mix; if it still feels cool or damp, your plant doesn't need water yet. Wait another few days and check again.

Another simple trick is to lift the pot. A freshly watered pot feels noticeably heavier than one that's ready for a drink, and over time you'll begin to recognise the difference without even thinking about it.

Finally, observe your plant. Healthy leaves that are firm and upright usually indicate your plant is comfortable, while slight drooping, dry potting mix and a lighter pot together often suggest it's time to water. Remember, yellow leaves are more commonly a sign of overwatering than underwatering during winter.

How to Water Properly

When your plant does need watering, water it thoroughly. Slowly pour water onto the soil until it drains freely from the bottom of the pot, then allow any excess water to drain away completely before returning the plant to its decorative pot or saucer. Never allow your plant to sit in water for extended periods, as constantly wet roots are one of the leading causes of root rot.

Every Plant is Different

A Peace Lily will usually need watering more often than a Snake Plant, and a Monstera beside a bright north-facing window will dry much faster than the same plant in a darker corner. Pot size, potting mix, light and humidity all influence how quickly the soil dries, which is why there's no perfect watering schedule.

Experienced plant owners don't ask, “How often should I water?” Instead, they ask, “Does my plant actually need water today?” That small shift in thinking changes everything.

If you're ever unsure whether to water, wait one more day.

Most indoor plants recover much more easily from being slightly dry than from sitting in constantly wet soil. When it comes to winter watering, patience is almost always rewarded.

 

Light Becomes Your Most Valuable Resource in Winter

If watering is the biggest adjustment you'll make during winter, light is the biggest opportunity.

As the days become shorter, the angle of the sun changes and the amount of natural light entering your home decreases. Even though your plant may be sitting in exactly the same spot it loved during summer, it could now be receiving significantly less light each day. For indoor plants, light is food: they use it to produce energy through photosynthesis, the process that fuels every new leaf, stem and root. When less light is available, they simply can't produce the same amount of energy, so growth naturally slows.

One of my favourite things about winter is how it encourages us to notice our homes differently. The afternoon sun reaches different corners of the room, windows that felt bright during summer become softer, and even moving a plant half a metre closer to a window can completely change how it performs over the coming months. Small changes often make the biggest difference.

Signs Your Plant Needs More Light

Not every plant will tell you in the same way, but these are some of the most common signs that your plant would appreciate a brighter position:

• New growth is smaller than usual.
• Stems become longer and stretch towards the nearest window.
• Variegated plants begin to lose some of their colour.
• Growth slows to a complete stop, despite otherwise healthy leaves.
• Your plant begins leaning noticeably towards the light source.

Remember, slower growth during winter is perfectly normal. However, if your plant is stretching in search of light, it's asking for a brighter position.

Move Your Plants Closer to the Window

One of the easiest ways to support your indoor plants during winter is to move them closer to a bright window. In many Australian homes, this simple adjustment is all that's needed. Aim for bright, indirect light wherever possible; most tropical houseplants don't enjoy harsh afternoon sun, but they do appreciate receiving as much gentle natural light as possible throughout the day.

If you live in the cooler southern states, avoid allowing leaves to rest directly against cold window glass overnight, as this can sometimes damage sensitive foliage.

Rotate Your Plants

Plants naturally grow towards their light source, so to encourage even, balanced growth, give each pot a quarter turn every week or two. This small habit helps prevent plants from becoming lopsided and encourages fuller, more symmetrical growth over time.

Keep Leaves Clean

Dust might seem harmless, but it acts like a thin curtain over your plant's leaves, reducing the amount of light they can absorb. During winter, when every hour of daylight counts, clean leaves make a surprising difference, and a soft damp cloth is usually all that's needed to remove dust and help your plant make the most of the available light.

Do You Need a Grow Light?

Not always. For many Australian homes, moving plants closer to a bright window is enough to keep them happy throughout winter. However, if your home receives very little natural light, particularly in apartments or heavily shaded rooms, a quality grow light can provide valuable additional light during the cooler months.

Position a grow light according to the manufacturer's recommendations and provide around 10 to 12 hours of light each day for most tropical indoor plants. Think of it as a helpful backup, not the first solution; often, the brightest spot in your home is all your plant really needs.

🌿 Carol's Golden Rule: Follow the light.

As the seasons change, don't be afraid to move your plants. They don't need to stay in the same place all year, and a small adjustment today can reward you with healthier, stronger growth when spring arrives.

Before investing in a grow light, try moving your plant closer to a bright window for two weeks. You'll often be surprised by how much difference this simple change can make, and it's completely free.

 

Should You Fertilise Indoor Plants During Winter?

As winter arrives, one of the most common questions I hear is: "Should I keep fertilising my indoor plants?" For most Australian homes, the answer is simple: probably not, or at the very least, much less than you do during spring and summer.

That often surprises people. After all, if fertiliser helps plants grow, wouldn't a struggling winter plant benefit from a little extra? In reality, the opposite is usually true.

Why Plants Need Less Fertiliser in Winter

Fertiliser isn't a magic tonic; think of it as fuel. During spring and summer, your plant is actively producing new leaves, extending its roots and putting on fresh growth, so it has the energy to use those nutrients. Winter is different: with shorter days and reduced light, your plant naturally slows its metabolism, growth becomes minimal, and its demand for nutrients decreases.

Adding fertiliser won't force a resting plant to grow. Without enough light to power photosynthesis, your plant simply can't make good use of the extra nutrients; instead, they remain in the potting mix where they can gradually build up around the roots. This can lead to fertiliser burn, unnecessary stress and, in some cases, damage to the delicate root system. More fertiliser doesn't solve a lack of light.

Let Your Plant Tell You

Rather than feeding on a schedule, watch your plant. Is it producing fresh leaves, are new stems appearing, and is it growing steadily? If the answer is no, it's probably telling you it's resting, and that's perfectly normal. One of the biggest lessons plants teach us is that rest isn't a sign of failure; it's a natural part of healthy growth.

When Should You Start Fertilising Again?

As winter begins to fade, you'll notice small changes: the days become longer, the afternoon sun feels stronger, and the soil starts drying a little faster. Then, almost without warning, you'll spot a tiny new leaf beginning to unfurl. That's your plant telling you it's ready to grow again, and once you see consistent new growth, you can gradually resume your normal fertilising routine.

Are There Any Exceptions?

Yes. Australia has an incredibly diverse climate, so if you live in tropical North Queensland or you're growing plants indoors under quality grow lights in consistently warm conditions, your plants may continue growing throughout winter. In those situations, a light application of fertiliser may still be appropriate, but the key is to let your plant guide your decision rather than the calendar.

Less is Often More

One of the biggest misconceptions in indoor plant care is that every problem needs a product. Sometimes we think another fertiliser, another supplement or another treatment will bring a struggling plant back to life, but more often than not, the answer is much simpler: better light, less water and a little patience.

Healthy plants are rarely the result of doing more; they're usually the result of doing the right things at the right time.

🌿 Carol's Golden Rule: Feed new growth, not dormant roots.

When your plant is actively growing, fertiliser helps support healthy development. When it's resting, the greatest gift you can give it is time.

If you're ever tempted to fertilise a plant that isn't growing, ask yourself one question first: Has the amount of natural light increased? If the answer is no, improving the light will almost always have a greater impact than adding more nutrients.

 

Temperature, Heating and Cold Drafts

Although your indoor plants are protected from the harshest winter weather, they're still affected by the changing conditions inside your home. In fact, sudden temperature changes often cause more stress than cool weather itself. Most popular indoor plants, including Monsteras, Philodendrons, Peace Lilies and Pothos, evolved in tropical and subtropical climates where temperatures remain relatively stable throughout the year.

During an Australian winter, however, they may experience cool nights, sunny afternoons, heaters, fireplaces and reverse-cycle air conditioning, sometimes all in the same day. It's these constant fluctuations, rather than winter itself, that can leave plants looking stressed.

The Ideal Temperature for Indoor Plants

Most tropical indoor plants are happiest when temperatures remain between 18°C and 24°C. Brief drops below this range usually aren't a problem, but prolonged exposure to temperatures below 10°C can slow growth significantly and, for some species, damage leaves and roots.

The good news is that most Australian homes naturally stay within a comfortable temperature range. Your goal isn't to create tropical conditions; it's simply to avoid sudden extremes.

Keep Plants Away from Heaters

It's only natural to move your favourite plant closer to the fireplace or heater during winter. After all, if we're cold, surely our plants are too? Unfortunately, plants experience heat very differently to us: fireplaces, portable heaters and reverse-cycle air conditioners create hot, dry pockets of air that quickly remove moisture from the leaves.

Over time this can cause:

• Brown leaf tips.
• Crispy leaf edges.
• Curling foliage.
• Dry potting mix near heating sources.
• Increased stress on humidity-loving plants.

Instead of placing your plants beside the heater, position them where the temperature remains more consistent throughout the day.

Be Careful Near Windows

Winter light is incredibly valuable, but windows can become surprisingly cold after sunset. If leaves are touching cold glass overnight, sensitive plants may develop brown patches or signs of cold damage. A small gap of just a few centimetres between your plant and the window is usually enough to prevent problems while still allowing plenty of natural light.

Watch for Cold Drafts

Cold air entering through frequently opened doors, older windows or poorly sealed areas can also affect tropical plants. If your favourite plant sits beside your front door or a drafty window, consider moving it to a more sheltered position until the weather warms; you'll often notice an improvement simply by relocating it a short distance.

Consistency is More Important Than Warmth

One of the biggest mistakes people make during winter is constantly moving their plants around the house: a sunny windowsill in the morning, beside the heater in the afternoon, and back into the living room at night. While the intention is good, these frequent changes can create more stress than simply leaving the plant in one bright, stable position.

Plants are remarkably adaptable. They don't expect perfect conditions; they simply appreciate consistency.

🌿 Carol's Golden Rule: Plants prefer steady conditions over perfect conditions.

A bright position with stable temperatures will almost always produce healthier plants than constantly chasing the warmest spot in the house.

Keep your indoor plants at least one metre away from fireplaces, heaters and air conditioning vents. While these appliances keep us comfortable, they create rapid changes in temperature and humidity that many tropical plants simply aren't adapted to handle. If you need to choose between more warmth or more natural light, almost always choose the light.

 

Humidity: The Hidden Challenge of Winter

When most people think about winter plant care, they think about watering. In reality, humidity is often the bigger challenge. Many of our favourite indoor plants, including Monsteras, Philodendrons, Peace Lilies, Calatheas and ferns, originate from tropical rainforests where the air is naturally warm and humid throughout the year.

During winter, the opposite often happens inside Australian homes. Heaters, fireplaces and reverse-cycle air conditioners all reduce the amount of moisture in the air, creating a much drier environment around your plants. While the roots may have plenty of water, the leaves can begin losing moisture faster than the plant can replace it, and that's when you'll often notice the first signs of stress.

Signs Your Plant Needs More Humidity

Dry air doesn't always look dramatic. In fact, it usually begins with small changes that are easy to overlook, so watch for:

• Brown or crispy leaf tips.
• Brown edges around otherwise healthy leaves.
• New leaves struggling to unfurl.
• Curling foliage.
• Dry-looking leaf margins.

These symptoms don't necessarily mean your plant needs more water. Very often, the soil is already moist and the surrounding air is simply too dry.

Simple Ways to Increase Humidity

The good news is that you don't need expensive equipment to create a healthier environment for your plants. A few simple changes can make a noticeable difference.

Group Your Plants Together

Plants naturally release moisture into the air through a process called transpiration. When several plants are grouped together, they create a small humid microclimate that benefits them all. It's nature helping nature.

Keep Plants Away from Dry Heat

Fireplaces, portable heaters and air conditioning vents create hot, dry air that quickly strips moisture from leaves, so whenever possible, position your plants a little further away where the temperature and humidity remain more stable.

Bathrooms and Laundries Can Be Wonderful Plant Rooms

If bathrooms or laundries receive enough natural light, they often provide ideal growing conditions for humidity-loving plants. The extra moisture produced by showers and washing naturally increases humidity, creating an environment many tropical plants love.

Closed Terrariums Create Their Own Climate

One of the reasons I love closed terrariums is that they do much of the work for you. Rather than constantly trying to increase humidity throughout an entire room, a closed terrarium creates its own small ecosystem where moisture continuously cycles within the glass, providing a stable, humid environment that many tropical plants naturally thrive in.

Should You Mist Your Plants?

This is probably one of the questions I'm asked most often. The answer is: not usually. While misting may briefly increase humidity around the leaves, the effect lasts only a short time, and by the time you've put the spray bottle away, the humidity has often returned to normal.

Instead of relying on frequent misting, focus on improving the growing environment itself. A brighter position, stable temperatures, grouping plants together or growing humidity-loving plants inside a closed terrarium will usually have a much greater impact over the long term.

Think Like the Plant

Rather than asking, "How can I add more moisture?", ask, "What kind of environment would this plant naturally grow in?" Once you begin thinking that way, many care decisions become surprisingly simple.

You're no longer trying to fix problems; you're simply recreating the conditions your plant already knows.

🌿 Carol's Golden Rule: Create the right environment, and your plants will do the rest.

Healthy plants are rarely the result of constant attention. More often, they're the result of being in an environment where they can quietly thrive.

If you love tropical plants but struggle with dry air during winter, consider starting with a closed terrarium. It naturally maintains humidity, requires very little watering and creates one of the easiest environments for many rainforest plants to flourish, making it a beautiful and low-maintenance addition to your home.

 

Keep Your Leaves Clean

Winter brings shorter days and fewer hours of sunlight, so every ray of light becomes more valuable. One of the simplest ways to help your indoor plants make the most of that light has nothing to do with watering or fertilising; it starts with clean leaves.

Over time, dust naturally settles on indoor plants. While it may not seem like much, this fine layer acts like a film over the leaf's surface, reducing the amount of light that reaches the plant. Because plants rely on light to produce energy through photosynthesis, dusty leaves become less efficient at making the food they need to stay healthy.

Why Cleaning Leaves Matters

Regularly cleaning your plants can help:

• Maximise the available winter light.
• Improve photosynthesis.
• Keep foliage looking healthy and vibrant.
• Make it easier to spot pests or disease.
• Remove household dust before it builds up.

Think of it as cleaning a window: the sunlight hasn't changed, but more of it can now reach your plant.

How to Clean Your Indoor Plants

Cleaning your plants only takes a few minutes and can easily become part of your winter care routine. For most plants:

• Use a soft microfibre cloth or a clean damp cloth.
• Support each leaf gently with one hand while wiping with the other.
• Use clean, lukewarm water only.
• Wipe both sides of larger leaves if they're dusty.

For plants with lots of small leaves, such as ferns, a gentle shower with lukewarm water is often the easiest option. Allow the foliage to dry before returning the plant to its usual position.

Should You Use Leaf Shine Products?

Many commercial leaf shine sprays promise glossy, healthier-looking foliage, but in reality, most indoor plants don't need them. Some products can leave a residue that blocks the tiny pores, called stomata, that plants use to exchange gases and regulate moisture.

A soft cloth and clean water are usually all you need. Healthy plants naturally develop a beautiful sheen when they're growing in the right conditions.

Turn Cleaning Into a Plant Health Check

One of my favourite things about cleaning leaves is that it encourages you to slow down. As you wipe each leaf, you'll naturally notice things you might otherwise miss: a tiny new leaf beginning to unfurl, a yellow leaf ready to remove, the first signs of a pest, or simply how well your plant is growing.

These quiet moments of observation often tell you far more than a watering schedule ever could.

🌿 Carol's Golden Rule: Healthy leaves help grow healthy plants.

A few minutes spent cleaning your plants every couple of weeks can improve their health, keep them looking beautiful and help you become a more observant plant owner.

Choose one day each fortnight as your "plant care day." Instead of rushing from plant to plant, take ten quiet minutes to check the soil, wipe the leaves and simply enjoy the greenery in your home. You'll be surprised how quickly you begin noticing the small changes that tell you exactly what your plants need.

 

Should You Repot Indoor Plants During Winter?

If your plant has roots appearing through the drainage holes or seems to have outgrown its pot, it's natural to wonder whether winter is the right time to repot. In most cases, the answer is simple: it's better to wait until spring. That advice isn't about following a gardening rule; it's about working with your plant's natural growth cycle.

Why Spring Is the Best Time to Repot

Repotting is one of the biggest changes we can make to a plant. Although it's often beneficial, it temporarily disturbs the root system while the plant settles into its new home. During spring and summer this usually isn't a problem, because longer days, warmer temperatures and stronger light encourage active root growth, allowing the plant to establish quickly in its new pot.

Winter is different. With less light available, most indoor plants slow their growth and produce fewer new roots, which means recovery takes longer. At the same time, fresh potting mix in a larger container holds more moisture, increasing the risk of overwatering while the roots are still inactive.

Waiting a few months allows your plant to recover faster and settle into its new pot with far less stress.

When Winter Repotting Can't Wait

Like most gardening advice, there are exceptions. Repotting shouldn't be delayed if:

• The pot has cracked or broken.
• Root rot has developed and damaged roots need to be removed.
• The potting mix has completely broken down and no longer drains properly.
• Water runs straight through the pot because the roots have become tightly compacted.
• The plant has become unstable and is in danger of tipping over.

In these situations, the benefits of repotting outweigh the risks.

What About Newly Purchased Plants?

One of the biggest misconceptions is that every new indoor plant should be repotted as soon as it comes home. In reality, healthy nursery plants are usually quite happy remaining in their original pot while they adjust to the different light levels, temperatures and humidity in your home.

Giving your plant a few weeks to settle before making major changes often leads to a healthier, stronger plant in the long run. Sometimes the kindest thing you can do is simply let your plant acclimatise.

If You Need to Repot During Winter

If repotting can't wait, a little extra care will help reduce stress.

• Choose a pot only one size larger than the current container.
• Use a premium, free-draining potting mix suited to your plant.
• Water lightly after repotting, avoiding waterlogged soil.
• Place the plant in bright, indirect light.
• Wait until you see fresh growth before fertilising.

The goal isn't to encourage rapid growth; it's simply to help the plant settle comfortably until spring arrives.

Patience Really Is Part of Plant Care

One of the things I love most about gardening is that it gently teaches patience. Not every problem needs fixing immediately, not every yellow leaf is an emergency, and not every healthy plant needs a bigger pot. Sometimes the best thing we can do is step back, observe and let nature work at its own pace.

More often than not, your plant already knows exactly what it's doing.

🌿 Carol's Golden Rule: Don't rush the roots.

Healthy roots are the foundation of every healthy plant. Give them time, work with the seasons and they'll reward you with stronger growth when spring returns.

Use winter as your planning season. Clean your pots, stock up on quality potting mix and make a list of the plants you'd like to repot in spring, so when the growing season arrives, you'll have everything ready and your plants will be perfectly timed for success.

 

10 Common Winter Indoor Plant Care Mistakes

Winter doesn't have to be the most difficult season for your indoor plants. In fact, once you understand how plants naturally respond to shorter days and cooler temperatures, it often becomes one of the easiest times of year to care for them. The challenge is that many of us continue caring for our plants as though it's still summer.

Here are the ten most common mistakes I see, and how you can avoid them.

1. Watering on a Schedule

It's easy to fall into the habit of watering every Sunday or every fortnight. During winter, however, your plant isn't following a calendar; it's responding to light, temperature and moisture. Always check the soil before watering.

🌿 Carol's Golden Rule: Trust the soil, not the calendar.

2. Overwatering

This is by far the most common cause of winter plant problems. Because plants grow more slowly and the potting mix stays wet for longer, watering too frequently can leave roots sitting in constantly damp soil. If you're ever unsure, wait another day and check again; your plant is far more likely to recover from being slightly dry than from developing root rot.

3. Forgetting That Light Has Changed

Many plants stay in exactly the same place all year, but the light doesn't. As the sun sits lower in the sky, rooms that were bright during summer can become surprisingly dim in winter, and even moving your plant a little closer to a window can make a remarkable difference.

4. Continuing to Fertilise

When plants aren't actively growing, they simply don't need the same amount of nutrients. Adding fertiliser during winter won't force a resting plant to produce new growth, so focus on providing plenty of light and resume feeding once fresh growth appears in spring.

5. Placing Plants Too Close to Heaters

It's natural to think your plants would enjoy the warmth, but heaters, fireplaces and air conditioning vents create hot, dry air that many tropical plants struggle with. Choose a bright position with a stable temperature instead.

6. Ignoring Dusty Leaves

A layer of dust may seem harmless, but it reduces the amount of light your plant can absorb. During winter, when every hour of daylight counts, clean leaves can make a surprising difference; think of it as giving your plant a clearer view of the sun.

7. Repotting Too Soon

Repotting is best saved for spring when plants are actively growing.

Unless there's a genuine problem with the roots or the pot, your plant will usually be happier staying exactly where it is until the weather warms.

8. Expecting Summer Growth

One of the biggest mistakes isn't something we do; it's something we expect. Many people worry when their Monstera stops producing leaves or their Pothos grows more slowly, but slower growth isn't a sign of failure. It's simply nature doing what it has always done.

🌿 Carol's Golden Rule: Rest is part of growing.

9. Moving Plants Too Often

Searching for the perfect spot can sometimes create more stress than leaving your plant where it is. Plants appreciate consistency, so if you've found a bright position with stable temperatures, resist the urge to keep moving them around the house.

10. Doing Too Much

This might be the most important lesson of all. Plants don't need constant attention, they don't expect perfect conditions, and they certainly don't need us trying to fix something every few days. Winter is a season of patience: observe more, intervene less, and sometimes the best care you can give your plant is simply allowing it to rest.

🌿 Carol's Golden Rule: Nature doesn't rush, and neither should we.

The Good News

If you've recognised yourself in a few of these mistakes, don't worry. Every experienced plant owner has made them. The wonderful thing about gardening is that it's a lifelong learning journey, and each season teaches us something new.

The more time you spend simply watching your plants, the easier caring for them becomes, and that's when indoor gardening becomes truly enjoyable.

 

Winter Care by Plant Type

While the principles of winter plant care remain the same, every plant responds a little differently to the changing seasons. Understanding what your particular plant needs will help you feel more confident and avoid making unnecessary adjustments during winter.

Monstera

Monsteras naturally slow their growth during winter, so don't be concerned if your plant isn't producing new leaves. This is completely normal.

Winter Care

• Allow the top few centimetres of potting mix to dry before watering.
• Position in bright, indirect light.
• Wipe the large leaves regularly to maximise photosynthesis.
• Pause fertilising until you notice fresh spring growth.

🌿 Winter Tip: Monsteras would much rather be slightly dry than constantly wet.

Peace Lily

Peace Lilies often continue growing slowly during Australia's milder winters, but they'll still need less water than they do during summer. Don't be alarmed if flowering slows or stops until spring.

Winter Care

• Water only when the soil begins to dry.
• Keep away from fireplaces and heaters.
• Provide bright, indirect light.
• Remove yellow leaves and spent flowers.

🌿 Winter Tip: If your Peace Lily droops, check the soil before watering. During winter, drooping doesn't always mean it's thirsty.

Pothos (Devil's Ivy)

Pothos is one of the most forgiving indoor plants and adapts beautifully to winter. Growth slows naturally, but healthy plants usually continue looking lush throughout the season.

Winter Care

• Allow the potting mix to partially dry between waterings.
• Move closer to bright, indirect light if growth becomes leggy.
• Rotate regularly for even growth.

🌿 Winter Tip: Bright light helps maintain the beautiful variegation on golden and marble varieties.

Snake Plant

Snake Plants are among the easiest indoor plants to care for during winter. In fact, most problems occur because they're given too much attention.

Winter Care

• Water sparingly.
• Keep in a bright position.
• Allow the potting mix to dry completely between waterings.
• Never leave the pot sitting in water.

🌿 Winter Tip: When in doubt, wait another week.

ZZ Plant

If you're looking for a low-maintenance indoor plant, the ZZ Plant is hard to beat.

Its thick underground rhizomes store water, making it extremely tolerant of dry conditions.

Winter Care

• Water only when the potting mix has dried well.
• Keep in bright, indirect light or medium light.
• Avoid overwatering.

🌿 Winter Tip: Overwatering is far more dangerous than underwatering.

Philodendron

Philodendrons appreciate consistency throughout winter.

While growth slows, they continue enjoying bright light and stable indoor conditions.

Winter Care

• Reduce watering.
• Keep away from cold drafts.
• Provide bright, indirect light.
• Wait until spring before fertilising.

🌿 Winter Tip: Healthy, glossy leaves usually indicate you've found the right balance.

Calathea

Calatheas are often considered one of the more challenging indoor plants, particularly during winter.

In reality, they're simply telling you when they're unhappy.

Most winter problems are caused by dry air rather than watering.

Winter Care

• Keep away from heaters.
• Maintain lightly moist soil without allowing it to become soggy.
• Group with other plants to improve humidity.
• Position in bright, indirect light.

🌿 Winter Tip: Brown leaf edges usually point to dry air before they point to underwatering.

Ferns

Many indoor ferns continue growing slowly throughout winter provided they receive enough humidity.

They're excellent indicators of dry indoor air.

Winter Care

• Keep the potting mix lightly moist.
• Increase humidity where possible.
• Avoid hot, dry air from heaters.
• Position in bright, indirect light.

🌿 Winter Tip: Bathrooms with good natural light often provide ideal winter growing conditions.

Closed Terrariums

Closed terrariums are one of the easiest ways to enjoy tropical plants throughout winter.

Because the glass enclosure creates its own humid microclimate, watering requirements are minimal and conditions remain remarkably stable.

This makes them one of my favourite indoor gardening projects during the cooler months.

Winter Care

• Place in bright, indirect light.
• Monitor condensation rather than watering on a schedule.
• If the glass remains heavily fogged for several days, remove the lid for an hour or two before replacing it.
• Avoid direct sunlight.

🌿 Winter Tip: Winter is often when closed terrariums perform at their very best, thanks to the stable temperatures and naturally high humidity inside the glass.

🌿 Carol's Golden Rule: Every plant is different, but every plant tells a story.

The more time you spend observing your plants, the more you'll begin recognising the small changes that tell you exactly what they need.

Confidence doesn't come from memorising care guides.

It comes from learning to listen to your plants.

 

Winter Indoor Plant Care Checklist

If you've made it this far, you'll already understand that successful winter plant care isn't about doing more.

It's about making a few simple adjustments and allowing your plants to follow their natural rhythm.

Use this checklist as a quick reminder throughout the cooler months.

Watering

☐ Check the soil before every watering.

☐ Water only when the top 3 to 5 centimetres of potting mix feels dry.

☐ Empty decorative pots and saucers after watering.

☐ Remember that most plants need less water during winter.

Light

☐ Move plants closer to bright, indirect light if needed.

☐ Rotate each plant a quarter turn every one to two weeks.

☐ Keep leaves clean to maximise winter sunlight.

Temperature

☐ Keep plants away from heaters, fireplaces and air conditioning vents.

☐ Protect sensitive plants from cold drafts.

☐ Leave a small gap between plants and cold window glass overnight.

Humidity

☐ Group humidity-loving plants together.

☐ Keep tropical plants away from dry heat.

☐ Consider a closed terrarium for plants that love humid conditions.

Plant Health

☐ Inspect leaves regularly for pests or signs of stress.

☐ Remove yellow or damaged foliage.

☐ Expect slower growth and don't mistake it for poor health.

Feeding & Repotting

☐ Pause fertilising until fresh spring growth appears.

☐ Wait until spring before repotting unless it's absolutely necessary.

Most Importantly...

☐ Slow down.

☐ Observe your plants.

☐ Enjoy the quieter pace of the season.

Winter is a time for both plants and people to rest.

Not every leaf needs fixing.

Not every pause means something is wrong.

Sometimes the healthiest thing we can do is simply give nature the time it needs.

Frequently Asked Questions

Why do indoor plants slow down during winter?

Most indoor plants naturally slow their growth during winter because there are fewer hours of daylight and lower light intensity. With less energy available through photosynthesis, plants produce fewer new leaves, use less water and require fewer nutrients. This seasonal slowdown is completely normal and is usually a sign that your plant is responding naturally to the changing seasons.

Should I water my indoor plants less during winter?

Yes, in most Australian homes your indoor plants will need less water during winter. Cooler temperatures and reduced light mean the potting mix stays damp for longer, so always check the soil before watering rather than following a fixed schedule.

Why are my plant's leaves turning yellow?

Yellow leaves are one of the most common signs of overwatering during winter. Before reaching for the watering can, check whether the soil is still damp. Yellowing can also be caused by poor drainage, reduced light, natural leaf ageing or sudden changes in temperature, so it's important to look at the whole plant rather than a single leaf.

My Monstera has stopped growing. Is something wrong?

Probably not.

Monsteras naturally slow their growth during winter. As long as the leaves remain healthy, the stems are firm and there are no obvious signs of pests or disease, your plant is most likely resting until spring.

Should I fertilise my indoor plants during winter?

For most Australian homes, it's best to pause fertilising until you notice fresh new growth in spring. Plants that aren't actively growing simply don't need the same amount of nutrients they do during the warmer months.

Is winter a good time to repot indoor plants?

Usually not.

Spring is the ideal time to repot because plants recover much faster while actively growing. The main exceptions are damaged pots, severe root rot or plants that have become badly rootbound and need immediate attention.

Should I mist my indoor plants?

Occasional misting provides only a short-term increase in humidity and usually isn't enough to make a lasting difference.

Creating a better growing environment by grouping plants together, moving them away from heaters or growing humidity-loving plants in closed terrariums is generally much more effective.

How much light do indoor plants need during winter?

As much bright, indirect light as possible.

Because daylight hours are shorter during winter, even moving your plant a little closer to a bright window can significantly improve its health and growth.

Can indoor plants survive near a heater?

Most tropical indoor plants dislike hot, dry air.

Fireplaces, portable heaters and reverse-cycle air conditioning can all reduce humidity and dry out leaves.

Whenever possible, keep plants at least one metre away from direct heat sources.

Which indoor plants are easiest to care for during winter?

Some of the easiest indoor plants for Australian homes during winter include:

• Snake Plant
• ZZ Plant
• Pothos (Devil's Ivy)
• Cast Iron Plant
• Closed Terrariums

These plants naturally tolerate lower light levels and require very little watering during the cooler months.

How often should I clean my plant's leaves?

Cleaning your plants every two to four weeks is usually enough.

Removing dust helps maximise photosynthesis, improves the appearance of your plants and makes it easier to spot pests or early signs of stress.

Are closed terrariums good during winter?

Absolutely.

Closed terrariums naturally create their own humid microclimate, making them one of the easiest ways to grow tropical plants throughout winter.

Because moisture continually cycles inside the glass, they require very little watering and remain remarkably stable during the cooler months.

What's the biggest mistake people make during winter?

Trying to care for their plants the same way they did in summer.

Winter asks us to slow down.

Water less.

Observe more.

Trust your plant to tell you what it needs.

Once you make that shift, winter often becomes the easiest and most enjoyable season of the year for indoor plant care.

Remember, every home is different.
The advice in this guide is designed to help you understand your plants, not give you rigid rules. Observe how your own plants respond to the changing seasons, adjust your care accordingly, and you'll soon develop the confidence that every successful plant owner shares.

 

Final Thoughts

One of the things I love most about indoor plants is that they quietly remind us to slow down.

In a world where we're constantly encouraged to do more, achieve more and move faster, plants follow a very different rhythm.

They don't rush. They don't compete. And they certainly don't apologise for taking a season to rest. Winter is their time to pause. To conserve energy. To strengthen their roots. To prepare for the growth that's still to come.

Perhaps we're not so different.

If your Monstera isn't producing new leaves, your Peace Lily has stopped flowering or your Pothos seems a little quieter than usual, don't assume you've done something wrong.

More often than not, your plant is simply doing exactly what nature intended. One of the greatest lessons plants teach us is that growth isn't always visible.

Some of the most important work happens beneath the surface, long before a new leaf begins to unfurl.

That's true in the garden. And, I think, it's true in life as well. So this winter, resist the urge to do more. Water a little less. Observe a little more. Move your plants towards the light. Enjoy the quieter pace of the season.

And remember that spring always comes.

Before you know it, those tiny new leaves will begin to appear again, reminding you that your patience has been worthwhile.

Thank you for spending a little time with me.

I hope this guide has helped you feel more confident, more connected to your plants and inspired to enjoy the slower rhythm that winter brings.

Happy growing.
