Grow loose-leaf lettuce varieties for repeated harvesting of outer leaves over a long season.
1 Sow Seeds Outdoors
Sow seeds thinly in rows or containers from 19th March - 30th April. Barely cover them with of compost, as they need light to germinate. Water gently and keep the soil cool; seeds won't germinate well if soil temperatures exceed .
2 Thin Seedlings
Thin seedlings to apart when they have their first true leaves, around 23rd April - 30th April. Use the thinnings as microgreens. This gives remaining plants room to develop.
3 Protect from Pests
Protect young plants from slugs and snails from 30th April - 14th May. Use organic methods like beer traps, copper tape, or hand-picking in the evening. Check regularly, especially after rain.
4 Water Consistently
Water plants regularly to keep the soil consistently moist from 29th September - 14th May. Dry soil can cause lettuce to bolt prematurely. Water at the base to avoid wetting the leaves, which helps prevent fungal diseases.
5 Harvest Outer Leaves
Start harvesting outer leaves from 29th September - 24th May. Pick leaves when they're large enough to use, cutting them near the base. Leave the central growing point intact so the plant continues producing new 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.
