Cucurbita pepo
A tender summer crop for the UK. Sow indoors in warmth, plant out after the last frost into rich, moisture-retentive soil, and keep picking young fruits to keep plants productive.
Step-by-step instructions for growing Courgette
Sow one seed on its edge in a small pot of warm compost around 17th March - 24th March. Keep the compost just moist and do not sow earlier, because seedlings grow fast and can become root-bound if left too long.
When 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 3rd April to 17th April.
Acclimatise plants outdoors over about 10 days from 7th April to 21st April. 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.
Plant into rich soil or a prepared mound around 21st April - 5th May 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.
From 12th June to 3rd November, 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.
Pick fruits from 2nd June to 3rd November while they are small and tender, ideally when they are long. Harvest often, because regular picking keeps the plant producing for longer.

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.
