Brussels Sprouts in Ardmore
Brassica oleracea (Gemmifera Group)
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.

Grow Brussels sprouts for a harvest from autumn through winter, with sprouts maturing from the bottom of the stalk upwards.
1 Sow Seeds Indoors
Sow seeds indoors in modules or pots around 25th March - 9th April. Use a good seed compost and cover with of soil. Keep at for germination, which takes 7-14 days.
2 Prick Out Seedlings
Once seedlings have their first true leaves, prick them out into individual pots around 15th April - 22nd April. Handle by the leaves to avoid stem damage and plant at the same depth as before.
3 Harden Off Plants
Gradually acclimatise plants to outdoor conditions over 7-10 days around 6th May - 13th May. Start with a few hours in a sheltered spot and increase exposure each day.
4 Transplant Outdoors
Plant seedlings into their final position around 23rd May - 6th June. Space them apart in firm, fertile soil. Firm the soil well around each plant to prevent wind-rock.
5 Install Pest Protection
Immediately after transplanting, cover plants with fine mesh netting to protect against cabbage white butterflies and pigeons. Fit brassica collars around the base of each stem to deter cabbage root fly.
6 Feed Plants
Apply a nitrogen-rich fertiliser every 28 days from 13th June until 22nd October. Water it in well to support the heavy leafy growth needed for good sprout formation.
7 Harvest Sprouts
Start harvesting from the bottom of the stalk upwards around 17th September - 22nd October. Pick sprouts when they are firm and about the size of a walnut. Frost improves their flavour, so continue harvesting through winter.

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 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.
