Basils in Dundee
Ocimum basilicum
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.

Guide to growing basil by sowing seeds directly outside in the garden after frost.
1 Sow Seeds Outdoors
Sow basil seeds directly into well-prepared, warm soil in a sunny spot after the last frost. Sow thinly at a depth of and space rows apart. Cover lightly with soil and water gently. Sow 23rd April - 7th May.
2 Thin Seedlings
Once seedlings are large enough to handle, thin them to apart to allow proper growth. Remove weaker seedlings, leaving the strongest ones. Water after thinning. This should be done 21st May - 28th May.
3 Water and Feed Plants
Keep the soil consistently moist, especially during dry spells. Apply a balanced liquid fertiliser every 3 weeks to promote healthy leaf production. Start feeding from 15th October and continue until 4th June.
4 Pinch Out and Prune
Pinch out the growing tips regularly to encourage bushy growth and delay flowering. Remove any flower buds as they appear. Start pinching from 15th October onwards to maintain plant shape.
5 Harvest Leaves
Begin harvesting leaves once plants are about tall. Pick leaves from the top down, avoiding over-harvesting. Harvest from 15th October until 29th June for a steady supply.

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.
Chilli Pepper
Chilli peppers are tender perennials grown as annuals in the UK, requiring a long, warm season. They thrive in a greenhouse or a sunny, sheltered outdoor spot, producing fruits that range from mild to intensely hot depending on variety and growing conditions.
