Courgettes in Penrhiwtyn

Sow one seed on its edge in a small pot of warm compost around 23rd March - 30th 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 9th April to 23rd April.

Acclimatise plants outdoors over about 10 days from 13th April to 27th 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 27th April - 11th 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 90 cm apart.

From 18th June to 9th 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 8th June to 9th November while they are small and tender, ideally when they are 10–15 cm long. Harvest often, because regular picking keeps the plant producing for longer.
