Step-by-step instructions for growing Courgette
Planting Calendar
Sow Seeds Indoors
14 Apr – 21 AprSow one seed on its edge in a small pot of warm compost around 14th April - 21st April. Keep the compost just moist and do not sow earlier, because seedlings grow fast and can become root-bound if left too long.
Pot On Seedlings
1 May – 15 MayWhen the first true leaves are formed, move each seedling into a larger pot so roots have room to develop. Handle them gently and keep them in good light from 1st May to 15th May.
Harden Off Plants
5 May – 19 MayAcclimatise plants outdoors over about 10 days from 5th May to 19th May. Start in a sheltered spot by day and bring them in at night, then leave them out longer each day until they cope with full outdoor conditions.
Transplant Outdoors
19 May – 2 JunPlant into rich soil or a prepared mound around 19th May - 2nd June once frost risk has passed. Water in thoroughly straight after planting, keep the stem base slightly raised above the surrounding soil, and space plants apart.
Water and Feed
10 Jul – 12 Octevery weekFrom 10th July to 12th October, water deeply at the soil rather than over the leaves, and avoid soaking the main stem. Begin feeding with a high-potash liquid feed once the first fruits set, then repeat every 7 days while plants are cropping.
Harvest Courgettes
30 Jun – 12 Octevery 3 daysPick fruits from 30th June to 12th October while they are small and tender, ideally when they are long. Harvest often, because regular picking keeps the plant producing for longer.

Why companion planting matters
Companion planting can deter pests, improve pollination, and make better use of space. Some plants confuse pests or attract beneficial insects; others improve soil or offer shade to neighbours that need it.

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.
