The easiest method for growing lettuce. Sow seeds directly in the ground for a continuous harvest through spring and autumn.
1 Prepare Soil
Choose a spot that gets full sun in spring or partial shade in summer. Work compost into the soil to improve drainage and fertility. Lettuce prefers loose, well-draining soil rich in organic matter.
2 Sow Seeds Outdoors
Sow seeds thinly in rows or broadcast across beds, covering with of soil. Space rows apart. Water gently to settle the soil. Seeds germinate best at .
3 Thin Seedlings
When seedlings reach tall, thin them to apart for leaf lettuce or apart for head lettuce. Use the thinnings in salads.
4 Water Regularly
Keep soil consistently moist throughout the growing period. Water in the morning to reduce disease risk. Lettuce needs about of water per week. Inconsistent watering leads to bitter leaves.
5 Succession Sow
Sow new seeds every 2 weeks from May through early summer for a continuous harvest. Stop sowing in hot weather and resume in late summer for autumn crops.
6 Harvest Leaf Lettuce
Begin harvesting outer leaves when plants are tall. Cut leaves about above the base to encourage regrowth. Harvest in the morning for best flavour.
7 Harvest Head Lettuce
Cut whole heads at the base when firm and full-sized. Harvest before hot weather causes bolting. Best picked in early morning when leaves are crisp.

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.
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.
Chilli Pepper
Chilli peppers are half-hardy annuals that produce an abundance of spicy, colourful fruits in warm conditions. They originate from tropical regions of the Americas and need a long growing season and plenty of heat to ripen their pods in the UK. Plants stay relatively compact (often 30–60cm tall) and grow well in containers or sheltered beds. There are countless varieties ranging from mild to extremely hot (measured in Scoville Heat Units), but all need sunshine and warmth to thrive.
