Winter is a rest season for houseplants, not a growth season. Days are shorter, evaporation slows, and heaters dry the air. Keep the summer watering schedule and roots rot easily.
Water Less, Don’t Stop Entirely
Stretch the time between waterings and always check the soil. Many plants need about half as many drinks as in summer. Use lukewarm water; icy water shocks roots. Empty saucers—water sits longer in winter.
Keep Pots Off Cold Glass and Away From Heaters
Leaves pressed against a freezing windowpane can scorch overnight. Leave a few centimeters of space. Direct heat from radiators and vents browns leaf edges. Don’t sandwich a plant between a heater and a cold window.
Take Winter Light Seriously
The sun sits lower and curtains often stay closed. Move pots to the safest closest spot by a window. Dust the leaves so they can catch more light. Pause fertilizer until you see spring growth.
Save Repotting for Spring
Roots repair slowly in the cold. Unless the plant is waterlogged or diseased, wait until early spring to change soil or pots. If you must repot, keep the plant out of harsh light and drafts afterward.
