Small-Space & Balcony Gardening
A Simple Season-by-Season Balcony Gardening Checklist
What to sow, plant, and do on your balcony each season — a straightforward year-round checklist for containers.
A balcony garden doesn’t stop in winter — it just changes job. Here’s what to sow, move, protect and tidy up each season, without needing a full gardening calendar to follow.
Spring (March–May)
The main planting season. Light and temperatures are rising, so this is when most containers get started or refreshed.
Spring tasks
- Top up or replace potting mix that's compacted over winter
- Sow quick crops: salad leaves, radish, herbs
- Move tender plants back out once the last frost has passed
- Start a weekly liquid feed once new growth appears
- Check pots for winter damage — cracks, blocked drainage holes
Summer (June–August)
Growth peaks, and so does water demand — this is the season most balcony plants are lost to drying out rather than anything else.
Summer tasks
- Water daily (sometimes twice) in hot spells, early morning if possible
- Deadhead flowering plants to keep them blooming
- Harvest herbs and salad regularly to stop them bolting
- Watch undersides of leaves for early signs of pests
- Add mulch (bark or gravel) to cut down on evaporation
Autumn (September–November)
Growth slows, but it’s a good window for hardy crops and for resetting containers before winter.
Autumn tasks
- Sow hardy salad leaves and overwintering herbs while soil is still warm
- Plant spring bulbs (tulips, daffodils) in pots for a spring show
- Clear spent summer plants and compost what you can
- Clean pots before storing or reusing them
- Reduce feeding as growth slows
Winter (December–February)
The quietest season, but not an empty one — the main job is protecting what you have.
Winter tasks
- Group pots together against a wall for shared warmth and wind shelter
- Wrap vulnerable pots (terracotta especially) in fleece or bubble wrap
- Water sparingly — only when the mix is dry a few centimetres down
- Check drainage holes aren't blocked by leaves or ice
- Plan next spring's crops while there's little else to do
Frequently asked questions
Do I need to bring all my plants indoors for winter?
No. Most hardy herbs and perennials tolerate cold on a balcony fine if grouped and protected from wind. Only genuinely tender plants (like basil or citrus) need bringing inside.
What can I still harvest in winter?
Hardy herbs like rosemary, thyme and sage keep going through mild winters, and overwintering salad sown in autumn can be picked in small amounts through the colder months.
When should I start feeding again in spring?
Once you see new growth, usually in March or April depending on your climate — feeding dormant plants too early wastes it, since they can't use the nutrients yet.
