Winter houseplant care depends on the plant, room temperature and available light, so a single ten-day watering rule is unreliable. Check how the root ball is drying before changing the amount or frequency of water.
Check the plant and the room
Winter changes a plant's surroundings, but indoor conditions vary. A warm room beside a bright window dries a pot differently from a cool hallway. Identify the plant and observe its growth before deciding whether it needs less water.
Read the root ball
Check below the surface and lift the container where practical. When water is needed, wet the root zone appropriately and let surplus water drain away. Do not keep a pot standing in a filled decorative cover. A ten-day or fortnightly schedule cannot account for every species, container and room.
Review light and feeding
Shorter days can make a previously suitable corner too dim. Move plants thoughtfully, checking for cold drafts or hot radiators at a new position. Feed according to active growth and the product label, rather than trying to force flowers on a resting plant. Keep notes on new leaves, buds and the drying rate of the pot; those observations make the next adjustment easier to judge.
