Winter Care for Indoor Plants

In winter your plants don't die of cold — they die because you keep caring for them like it's summer. With less light and less warmth, most of them slow right down and their needs change completely. Adjust these five things and they'll reach spring strong.

1. Water far less

This is the number one winter mistake. With low light and cool temperatures, the soil takes much longer to dry and the roots drink less. If you watered weekly in summer, in winter it might be every two or three weeks.

• Always check before watering: push a finger 1-2 inches into the soil. If it's damp, wait.
• Empty the saucer: standing water in winter is the perfect recipe for root rot.
• Use room-temperature water, never cold from the tap, so you don't shock the roots.

Winter golden rule: when in doubt, don't water. This time of year overwatering kills far more plants than drought.

2. Move them toward the light

Days are shorter and the sun is weaker. Move your plants closer to windows, ideally south- or west-facing, so they catch every hour of light.

• Clean the glass: a dirty window steals light.
• Wipe the leaves with a damp cloth so they absorb light better.
• Turn the pot a quarter turn each week so it doesn't lean.

If your home is very dark, consider adding artificial light or review which plants tolerate low light.

3. Keep them away from radiators and drafts

The biggest winter enemy is dry air and sudden temperature swings.

• No radiators: dry heat scorches the tips and dries the soil out fast.
• Watch for cold drafts from windows and doors; a freezing night pressed against the glass can damage tropical leaves.
• Keep most houseplants between 60 and 72 °F.

4. Pause feeding

If the plant isn't growing, it doesn't need to eat. Fertilizing during the slowdown just builds up salts in the soil and can burn the roots.

• Stop feeding from late autumn until you see new growth in spring.
• Exception: plants that bloom in winter, like the Christmas cactus, do appreciate a gentle feed while flowering.

5. Raise the humidity

Heating dries the air to desert levels, and tropicals suffer with brown, crispy tips.

• Group plants together: as a cluster they create a humid microclimate.
• Use a humidifier, or set pots on a tray of pebbles and water (base not touching the water).
• Don't over-mist: in winter water sits on the leaves and slowly evaporates, which invites fungus.

Signs something is wrong

Symptom	Likely winter cause
Yellow, soft leaves	Overwatering
Brown, dry tips	Dry air from heating
Long, weak stems	Not enough light (etiolation)
Sudden leaf drop	Cold draft or sharp change

What NOT to do in winter

• Don't repot unless it's an emergency: the plant has no energy to recover. Wait for spring.
• Don't force growth with extra water or feed; respect its rest.
• Don't panic if it drops an old leaf or two — that's normal this time of year.
• Don't buy new tropicals on a freezing day and carry them home uncovered: a short walk in the cold can shock or even kill a tender plant. Wrap it well and let it acclimatise indoors before you do anything else.

Caring for plants in winter is mostly about doing less: less water, less feed, no repotting. Give them light, protect them from dry air, and let them rest. Is your plant looking off and you're not sure if it's cold, overwatering or something else? Try it in our AI diagnosis and find out.
