🌱 What Vegetables to Start in February for Summer Harvest

🧅 Onions (From Seed)
One of the most important February sowings.
How to start:
- Sow in trays or modules

Early sowing leads to stronger plants and larger bulbs by summer.
🥬 Leeks
Leeks need time to bulk up properly.
How to start:
- Sow thinly in trays or modules
- Grow on indoors until planting out
Why start now:
February sowings produce thicker stems and better yields.
🥦 Brassicas (Summer & Autumn Crops)
Includes:
- Cabbage
- Calabrese
- Cauliflower
- Brussels sprouts
How to start:
- Sow in modules under cover
Why start now:
Creates strong transplants ready for early planting out and reliable summer crops.
🌿 Celery
A slow-growing crop that needs an early start.
How to start:
- Surface sow (do not cover seed)
- Keep warm and moist
Why start now:
Celery requires a long growing season to reach full size by summer.
🌶️ Chillies & Peppers
Essential February sowings for summer harvests.
How to start:
- Sow in trays or modules
- Maintain 20–25°C
Why start now:
Slow germination and long seasons mean late sowing reduces yields.

Only suitable if conditions are right.
How to start:

- Provide maximum light
Why start now:
Early sowings give earlier and heavier summer harvests.

Best started under cover.
How to start:
- Sow in guttering, pots, or modules
- Protect from mice
Why start now:
Strong transplants establish quickly and crop earlier.
🧄 Garlic & Shallots (Last Chance Planting)
Can still be planted outdoors if soil allows.
Why start now:
Later planting reduces bulb size, so February is the final window.
❄️ February Starting Tips for Summer Crops
- Prioritise light over warmth once seeds germinate
- Avoid overwatering cold compost
- Sow little and often rather than everything at once
- Harden off plants gradually before planting out
⚠️ Vegetables Better Left Until March or April
Avoid starting these too early:
- Courgettes
- Squash
- Sweetcorn
- Climbing beans
They grow too quickly and become unmanageable indoors.
