How does houseplant care change in winter?

Shorter, weaker days slow most plants down, so they need less of almost everything: less water, no fertiliser, and protection from cold draughts and dry radiator heat. The summer routine that kept them thriving can drown or overfeed them now.

How often should I water houseplants in winter?

Less often than in summer. Growth slows, so soil stays wet longer — keep checking the top few centimetres and only water when it's dry. For many plants that stretches waterings to every couple of weeks or more.

Should I fertilise houseplants in winter?

Usually not. Most plants pause growth and can't use the nutrients, so feeding risks salt build-up that burns the roots. Wait until early spring when new growth appears.

Winter houseplant care: what changes and what to stop doing

Published 31 July 2026

Most houseplants don’t die in winter from cold — they die from being cared for as if it were still summer. As the days shorten and light weakens, growth slows to a crawl, and a plant that’s barely growing needs far less of everything. The routine that kept it thriving at the height of summer becomes too much water, too much food, and too much fuss by the depths of winter.

Winter care is mostly about doing less, on purpose.

Why winter changes everything

Plants run on light. Shorter, dimmer days mean less photosynthesis, which means slower growth and slower water use. Nothing about the plant’s needs is fixed — they scale with the light it’s getting, and in winter that light drops sharply. (It’s the same reason light drives watering year-round.)

Water less — and check, don’t schedule

This is where most winter losses happen. A plant using less water sits in wet soil longer, and soggy soil in low light is a fast road to root rot. Keep reading the plant instead of the calendar: feel the soil, lift the pot, and wait until it’s genuinely dry. Expect to water noticeably less often than in summer.

Ease off the fertiliser

A dormant or slow-growing plant can’t use much feed, and unused fertiliser builds up as salts that burn the roots. For most plants, stop or sharply reduce feeding through the darkest months and resume as growth picks up in spring.

Mind light, draughts, and radiators

Move plants closer to windows to claw back some of the lost light, and clean dust off the leaves so they catch what’s there.
Keep them away from cold draughts and from hot, dry radiators and heating vents — both stress a plant fast.
Watch for dry indoor air; some tropicals appreciate a little more humidity in a heated room.

Don’t repot now

Winter is the wrong time for repotting — it’s minor surgery, and a slow-growing plant recovers poorly. Unless it’s an emergency (like severe root rot), wait for spring.

Let the season set the pace

The single biggest winter mistake is holding a plant to its summer rhythm. The right rhythm isn’t a fixed schedule at all — it shifts with the season, the light, and the room. That’s exactly what Foliora tracks: it factors the season and each plant’s actual light into its care, and eases the rhythm back as the days shorten — so you’re not drowning a resting plant out of habit.
