1 Sow Seeds Indoors
Sow seeds in modules or trays from 26th February - 12th March. Cover lightly with of compost and keep at for germination. Provide bright light to prevent leggy seedlings.
2 Prick Out Seedlings
Prick out seedlings into individual pots when they have two true leaves, around 19th March - 26th March. Handle them by the leaves to avoid damaging the stems. Grow them on in a cool, bright spot.
3 Harden Off Plants
Harden off plants over 7-10 days before transplanting, from 2nd April - 9th April. Gradually expose them to outdoor conditions by placing them outside during the day and bringing them in at night.
4 Transplant Outdoors
Transplant seedlings outdoors from 9th April - 23rd April. Space them apart in well-drained soil. Water in well and protect from slugs with organic deterrents.
5 Water and Feed
Water regularly to keep soil moist and apply a balanced liquid feed every two weeks from 15th October - 30th April. Consistent moisture prevents bolting and encourages firm heart formation.
6 Harvest Whole Heads
Harvest heads when they feel firm and full, from 15th October - 5th June. Cut the entire head at the base with a sharp knife. Harvest in the morning for the crispest leaves.

Basil
Basil is a fragrant, tender herb whose leaves are a staple of summer cooking. Native to tropical regions, basil is treated as an annual in temperate climates like the UK because it cannot tolerate frost. It thrives in warm, sunny conditions and can be grown in garden beds or pots for a steady supply of fresh, flavourful leaves throughout the summer.
Brussels Sprouts
Brussels sprouts are a hardy winter brassica (cabbage family) that form sturdy, leafy stems often around 60–90cm tall. They produce edible mini-cabbage buds along the stem from autumn through winter. Thanks to their cold tolerance, sprouts remain productive into late winter, and frost actually improves their sweetness.
Calabrese
Calabrese (broccoli) produces a large central head of tightly-packed green buds, followed by smaller side-shoots after the main head is cut. It’s a cool-season brassica crop. Grow it in full sun with fertile, well-drained soil and keep plants watered during dry spells. Harvest the heads while firm, then leave the stem in the ground to allow side-shoots to develop.
