When to Start Planting for Winter Crops
To enjoy fresh vegetables through winter, most sowing and planting needs to be done by late summer to early autumn:
| Task | Best Time (UK) |
|---|---|
| Sow winter crops indoors | July–September |
| Transplant to beds | August–October |
| Direct sow hardy veg | August–early October |
| Protect crops | October onwards |
Tip: Use a cold frame, cloche, or greenhouse to extend your planting window and protect young plants.

How to Prepare Your Garden for Winter Growing
🌿 1. Clear and Clean Up
- Remove spent summer crops and weeds
- Turn compost into the soil if needed
- Clean tools, containers, and raised beds
🌾 2. Improve the Soil
- Add well-rotted compost or organic matter
- Mix in leaf mould or garden compost to retain moisture
- Avoid rich nitrogen feeds—many winter crops prefer leaner soils
🧼 3. Plan Your Layout
- Group similar crops (e.g. brassicas together)
- Rotate crops to reduce disease
- Position crops to take advantage of sunlight and shelter
🧱 4. Add Protection
- Set up cloches, fleece, cold frames, or polytunnels
- Use windbreaks in exposed sites
- Raise beds slightly for better drainage
Growing Winter Veg in Containers or Raised Beds
Even with limited space, you can still enjoy winter veg!
✅ Raised Beds
- Excellent drainage in wet months
- Easier to cover with cloches or tunnels
- Grow kale, chard, onions, garlic, and brassicas
✅ Containers
- Use deep pots (20–30cm) with drainage holes
- Fill with peat-free multipurpose compost + grit
- Best for spinach, rocket, spring onions, herbs, baby carrots
🪴 Windowsills and Indoor Spaces
- Grow microgreens, herbs, and cut-and-come-again leaves
- Use a sunny windowsill or add grow lights for darker months
Cold Protection: How to Shield Your Winter Crops
| Method | Use For | Benefits |
|---|---|---|
| Horticultural fleece | Covering beds, low tunnels | Lightweight frost protection |
| Cold frames | Spinach, lettuce, herbs, seedlings | Extends season into winter/spring |
| Polytunnels | Full winter crop growing | Protects from wind and snow |
| Cloche tunnels | Rows of greens or roots | Quick to set up and move |
| Mulching | Roots, garlic, onions | Insulates soil and prevents freezing |
Watering and Feeding Winter Crops
💧 Watering Tips
- Water less frequently in winter
- Check soil before watering—too much water causes rot
- Lift pots off the ground to prevent waterlogging
🌿 Feeding Tips
- Most winter veg need minimal feeding
- Use a slow-release organic fertiliser at planting time
- Avoid high nitrogen in winter—it can cause soft, frost-damaged growth
Harvesting Your Winter Vegetable Garden
| Crop | Harvest Notes |
|---|---|
| Kale & Chard | Cut outer leaves and let centre regrow |
| Spinach & Oriental Greens | Pick young leaves regularly (cut-and-come-again) |
| Carrots, Parsnips, Swede | Leave in ground; lift when needed |
| Garlic & Onions | Harvest in early spring if planted in autumn |
| Brussels & Broccoli | Pick from lower stalks upward |
Tip: Avoid harvesting frozen plants—wait for them to thaw to avoid damage.
Winter-Friendly Herbs to Grow
| Herb | Notes |
|---|---|
| Parsley | Hardy biennial; good in pots or beds |
| Thyme | Tough perennial, thrives in poor soil |
| Sage | Evergreen; needs shelter in hard frosts |
| Chives | Die back in winter, regrow in spring |
| Rosemary | Hardy shrub; great for winter flavouring |
Grow in pots or near the kitchen door for easy access on frosty days.
Common Winter Growing Problems and Solutions
| Issue | Symptoms | Solution |
|---|---|---|
| Frost damage | Wilted, blackened leaves | Use fleece, cloches, or polytunnels |
| Waterlogged soil | Yellowing, soft roots | Improve drainage, mulch beds, use raised containers |
| Slugs and snails | Holes in leaves, slime trails | Use beer traps, wool pellets, or crushed eggshell barriers |
| Pigeons or rabbits | Missing tops, broken stems | Netting or fleece tunnels as protection |
| Slow growth | Lack of sunlight or cold soil | Use cold frames or plant cold-hardy varieties |
Companion Planting for a Winter Garden
| Crop | Good Companions | Benefits |
|---|---|---|
| Brassicas | Onions, garlic, chard | Deters pests, improves soil health |
| Spinach | Spring onions, lettuce | Shade-tolerant, share space well |
| Carrots & Parsnips | Leeks, rosemary | Break up soil and repel pests |
Succession Planting for Continuous Harvests
To keep your winter garden productive:
- Sow little and often (every 2–3 weeks) from late summer
- Replace harvested crops with quick-growing greens
- Use cloches or covers to warm soil for next sowings
Creating a Winter Garden Schedule
| Month | Key Tasks |
|---|---|
| August | Sow winter greens, carrots, onions |
| September | Plant garlic, late spinach, protect seedlings |
| October | Add fleece, build cloches or cold frames |
| November | Mulch beds, harvest root veg |
| December | Pick kale, chard, leeks; monitor protection |
| January | Sow indoors, tidy beds, prep early sowings |
| February | Start spring veg indoors, harvest last of winter crops |
