How to Sow
- Sow seeds 1-2cm deep in modules filled with seed compost
- Transplant to final position when seedlings have 4-6 true leaves
- Space plants 60cm apart in rows 60cm apart
- Firm soil well around each plant — brassicas need solid anchorage
- Choose a sunny, open position with fertile, well-drained soil
Plant Care
- Net against pigeons and cabbage white butterflies immediately after planting
- Water well during dry spells, especially after transplanting
- Stake tall plants in exposed sites — they can reach 90cm
- Check regularly for caterpillars and remove by hand
- Earth up the stems in autumn for extra stability over winter
AllotMe’s Tips
- Purple sprouting broccoli fills the 'hungry gap' (Feb-April) when little else is ready — it's invaluable on an allotment
- 'Early Purple Sprouting' is the most reliable variety for UK growing
- Once you cut the central head, the plant produces masses of smaller side shoots over 6-8 weeks — don't pull the plant up too soon!
