Winter Houseplant Care: How to Keep Indoor Plants Alive

8 min read

Last updated November 9, 2026

Winter is hard on houseplants. Days are short, indoor heat dries the air, and cold windows can chill leaves overnight.

The good news is that most plants only need a few changes to get through the season. This guide covers light, watering, humidity, placement and pests, so your plants reach spring healthy.

Key Takeaways

Most houseplants grow slowly in winter, so they need less water.
Check the soil before watering and wait until it feels dry.
Raise humidity with a humidifier, pebble trays or by grouping plants.
Keep plants away from drafts, heaters and very cold glass.
Skip fertilizer and repotting until spring.

Why Houseplants Slow Down in Winter

Plants run on light. When days get shorter, most houseplants slow their growth and use less water and food.

Debra Heleba, a community horticulture program manager at University of Vermont Extension, explains this in her winter houseplant guide. Some plants rest more deeply than others.

Alocasias and caladiums may drop leaves, which is normal.
Cacti and succulents often go into a deep rest.
Tropical foliage plants keep their leaves but grow very little.

Knowing this helps you avoid the most common winter mistake. That mistake is treating a resting plant like a summer plant.

How to Water Houseplants in Winter

Overwatering kills more houseplants in winter than anything else. Slow-growing plants cannot use much water, so wet soil sits around the roots and can cause rot.

Check before you water

Push your finger into the soil about an inch deep.
Or push a wooden chopstick into the pot and pull it out.
If soil sticks to the stick, wait a few more days.
A simple moisture meter can also help.

Water only when the soil feels truly dry. For many plants, that means watering every two to three weeks instead of every week.

Water the right way

Use room-temperature water, since cold water can shock roots.
Water slowly until a little drains from the bottom.
Empty the saucer after 15 minutes so roots do not sit in water.
Water in the morning so leaves dry before the cooler night.

How to Give Plants Enough Light

Winter sun is weaker and lower in the sky. A spot that worked in summer may be too dark now.

Move plants closer to your brightest window, usually one facing south or west.
Rotate pots a quarter turn each week so all sides get light.
Wipe dust off leaves with a damp cloth so they can absorb more light.
Pull back curtains during the day.

Try a grow light

If your home is dark, a simple, energy-efficient grow light can help. Place it a short distance above your plants and run it for part of the day on a timer.

Watch your plants for clues. Long, stretched stems and pale leaves often mean a plant wants more light.

How to Raise Humidity

Indoor heating dries the air, and tropical plants feel it first. Brown, crispy leaf tips are a common sign.

Method	How it works	Cost
Humidifier	Adds moisture to the air in the room	Moderate
Pebble tray	Water evaporates around the pot	Low
Grouping plants	Plants release moisture that helps their neighbors	Free
Bathroom or kitchen	These rooms are often more humid	Free

To make a pebble tray, fill a shallow tray with pebbles. Add water until it sits just below the tops of the stones. Set the pot on the pebbles so it does not sit in water.

Misting feels helpful but only raises humidity for a few minutes. A humidifier or pebble tray works better.

Where to Put Houseplants in Winter

Steady temperatures keep plants happy. The Vermont guide warns against three spots in particular.

Drafty doors and windows. Cold blasts can damage leaves.
Heat sources. Vents, radiators and wood stoves dry plants out fast.
Right against the glass. Windows can get very cold at night.

Pull plants back a few inches from the window on cold nights. Never let leaves touch frosty glass.

Sealing drafts helps both you and your plants. See our guide on how to insulate windows for winter.

Keep your thermostat steady as well. Our tips on smart thermostat settings for winter can help you avoid big temperature swings.

Fertilizer and Repotting

Most houseplants do not need fertilizer in winter. They are not growing much, so extra food can build up in the soil and burn the roots.

Wait until spring to repot as well. Repotting stresses a plant, and a resting plant recovers slowly.

The exception is a plant that is actively growing or blooming under good light. In that case, a light feeding can help.

Keep an Eye Out for Pests

Dry indoor air can invite some pests. The Vermont guide suggests checking plants while you clean their leaves.

Pest	What to look for
Spider mites	Fine webbing under leaves
Aphids	Sticky residue on leaves
Mealybugs	White, cottony clumps
Scale	Small bumps on stems
Fungus gnats	Tiny flies near wet soil

Fungus gnats love soggy soil. Letting the soil dry between waterings and using yellow sticky traps can help.

Isolate any plant with pests so the problem does not spread. Wipe leaves or rinse them gently in a lukewarm shower, letting the pot drain fully afterward.

Troubleshooting Winter Problems

Problem	Likely cause	Fix
Yellow lower leaves	Too much water	Let soil dry out more
Brown, crispy tips	Dry air	Add a humidifier or pebble tray
Leggy, pale growth	Not enough light	Move closer to a window or add a grow light
Sudden leaf drop	Cold draft or move	Find a steadier spot
Mushy stems	Root rot	Cut back water and check the roots

Some leaf loss is normal in winter. Focus on new growth in spring as the real sign of health.

How to Clean Houseplant Leaves

Dust blocks light from reaching the leaf. In winter, when light is already scarce, clean leaves make a real difference.

Support each leaf with one hand.
Wipe the top and bottom gently with a soft, damp cloth.
Use lukewarm water only, with no leaf shine products.
For small or fuzzy leaves, use a soft paintbrush instead.
Let leaves dry before moving plants back to a cool window.

Cleaning also gives you a close look at each plant. It is the perfect time to spot pests early.

Winter Care for Succulents and Cacti

Succulents and cacti need the most light and the least water of any common houseplant. In winter, many go almost fully dormant.

Give them your sunniest window.
Water only about once a month, or when the soil is bone dry.
Keep them on the cool side, away from heaters.
Watch for stretched, leaning growth, a sign they need more light.

A cool, bright, dry winter can even help some cacti bloom in spring. Resist the urge to water them often.

Houseplants, Pets and Kids

Plants often move to new spots in winter, sometimes within reach of pets and small children. Some popular houseplants can upset the stomach or irritate the mouth if chewed.

Check whether your plants are safe before you place them on low tables or floors. When in doubt, move them to a high shelf or a room pets cannot reach.

Going Away in Winter

Holiday travel can leave plants alone for a week or more. A few simple steps help them cope.

Water well a day before you leave, then let the pots drain.
Group plants together in a bright room away from heaters.
Set the thermostat no lower than a comfortable indoor level for plants.
Ask a friend to check on thirsty plants if you will be gone long.

Because plants use less water in winter, most will be fine for a week or two. Tropical plants in small pots dry out fastest.

Move plants back to their usual spots when you get home. Check the soil first, and water only the pots that feel dry.

Easy Plants for Winter Beginners

Some houseplants handle low light and dry air better than others. They make great choices for winter.

Snake plant, which tolerates low light and little water
Pothos, which forgives missed waterings
ZZ plant, which stores water in its thick stems
Cast iron plant, known for being nearly impossible to kill
Spider plant, which adapts to many conditions

Holiday plants need special care too. Read our poinsettia care tips to keep yours colorful.

Signs Your Plant Is Doing Well

A healthy plant in winter does not need to grow fast. Look for these quieter signs instead.

Leaves stay firm and keep their color.
Stems stand up without drooping.
Soil dries out within a week or two after watering.
No webbing, sticky spots or tiny flies appear.
A new leaf shows up now and then.

If your plants show most of these signs, your winter routine is working. Keep it steady until spring arrives.

A Simple Winter Plant Routine

How often	Task
Every few days	Check soil moisture
Weekly	Rotate pots and check for pests
Every two weeks	Wipe dust off leaves
Monthly	Refill pebble trays and clean the humidifier
Early spring	Repot and start fertilizing again

Test Yourself

What is the most common winter houseplant mistake?

Overwatering
Too much fertilizer in summer
Using clay pots

Resting plants use little water, so wet soil can rot their roots.

When should you repot most houseplants?

In midwinter
Right after the holidays
In spring

Plants recover faster from repotting when they start growing again in spring.

Frequently Asked Questions
