A Seasonal Houseplant Care Calendar

Plants don't need the same things in July as they do in January. They follow the rhythm of the seasons: growing strongly when there's light and warmth, and slowing down as the days shorten. Matching your care to that calendar is the difference between a collection that thrives and one that struggles. Here's a season-by-season guide to what to do at each point in the year.

Spring: the plant wakes up

This is the headline season. With more light and warmth, plants kick back into growth and welcome a boost.

• Watering: increase it gradually as the soil dries out faster.
• Feeding: resume fertilizing every 2-4 weeks while the plant is actively growing.
• Repotting: this is the best time of year to move up a pot size, because the plant recovers quickly. Follow the steps in our guide on how to repot a plant.
• Pruning and cleaning: remove dead leaves and shape the plant to encourage new growth.

Summer: peak growth (and watch the heat)

Plants grow flat out, but extreme heat and direct sun can take a toll.

• Watering: this is when they need the most water; check the soil every few days, especially in small or terracotta pots.
• Light: shield them from harsh midday sun through glass, which scorches leaves.
• Humidity: with dry air or air conditioning, group plants or use a humidifier.
• Holidays: arrange watering if you're away; practical ideas in our guide on watering while away.
• Pests: watch for spider mites and thrips, which explode in the heat.

Autumn: easing off

The days shorten and the plant starts to slow. Your job is to ease it down gently.

• Watering: reduce it gradually; the soil takes longer to dry.
• Feeding: space it out and stop toward the end of the season.
• Repotting: avoid it unless urgent; better to wait for spring.
• Placement: move plants closer to windows to make the most of the fading light.
• Heating: when you switch it on, keep plants away from radiators and watch the humidity.

Winter: rest

Most houseplants enter a resting phase. Less light means less growth and, therefore, less care.

• Watering: far less. Water only when the soil is dry deep down; overwatering in winter is the leading cause of rot.
• Feeding: pause it almost entirely until spring.
• Light: place plants in the brightest spots in the house.
• Temperature: protect them from cold windows at night and from drafts.
• Don't panic if they stop growing or drop the odd leaf — it's normal this time of year.

Tasks for all year round

Some care doesn't care about seasons:

• Rotate pots a quarter turn each week so plants grow straight.
• Wipe dust off leaves so they breathe and capture light better.
• Check leaf undersides for pests whenever you water.
• Remove dead leaves to prevent fungus and keep the plant healthy.

Adapt the calendar to your home

This calendar is a general guide for the Northern Hemisphere; if you live in the South, flip the seasons. A home with strong heating or lots of windows can also shift these rhythms. Always watch your plant — it will tell you whether it needs more or less.

If at any point in the year your plant shows odd signs you can't read, take a photo and run it through our AI diagnosis tool to find out what's going on.

With these seasonal tweaks, your plants will grow strong in spring and summer and rest easy in autumn and winter, ready to flush again.
