How to Care for Houseplants in Winter

In winter, most houseplants grow slowly, so water less, skip most fertilizer, give them as much light as you can, and keep them away from cold drafts and hot vents. The changes are mostly about doing less.

Why do plants need different care in winter?

Days are shorter, light is weaker, and many rooms are cooler or drier. Plants use less water and grow slowly, so they need less of almost everything except light.

How should I change watering?

Water less often, and check the soil before watering. Soil dries out more slowly in cooler, dimmer conditions, so a summer schedule can lead to overwatering. Succulents may need water only about once a month or less. See how often should you water succulents?.

Should I fertilize in winter?

Usually not, or very little. Most plants are not actively growing, and unused fertilizer can build up in the soil. Resume in spring as growth picks up. See how often to fertilize houseplants.

How do I give plants enough light?

Move them closer to windows, and clean dusty leaves and windows so more light gets through. Rotate plants so they grow evenly. See how much light houseplants need.

What about drafts and heaters?

Keep tropical plants away from cold windows, outside doors, and drafty spots, and away from radiators and heating vents, which dry out leaves fast. Leaves touching cold glass can be damaged.

What about humidity?

Heating can make indoor air very dry. A humidifier can help humidity-loving plants. See should you mist houseplants?.

Should I repot in winter?

Avoid it unless necessary, such as for root rot. Wait for spring.

What about pests?

Dry, warm rooms can encourage pests like spider mites, so keep checking leaves.
