Pot On Seedlings
30 Mar – 13 AprMove seedlings on when roots fill the module, keeping them growing steadily before planting out. Handle them by the leaves, not the stems, and keep them in bright light so they do not get leggy.
Harden Off

Transplant as Companion Plants
2 May – 16 MayPlant them out around 2nd May - 16th May into a sunny, free-draining position, spacing them apart. Water in thoroughly straight away, then grow them near tomatoes to help deter whitefly and add a useful flowering strip among crops.
Deadhead & Maintain

Sweetcorn
Sweetcorn is a tall annual plant grown for its sweet, juicy cobs. It thrives in warm, sunny conditions and must be planted after the last frost. Plants are wind-pollinated, so for best results grow them in blocks rather than single rows, ensuring well-filled cobs. With good care and warm weather, sweetcorn will reward you with delicious fresh corn-on-the-cob in late summer.
Garlic
Garlic is a hardy, sun-loving bulbous vegetable from the onion family, grown for its pungent cloves used in cooking. It’s easy to grow in a warm, well-drained spot and needs minimal fuss – plant individual cloves and they will develop into full bulbs by the following summer. Most garlic varieties require a cold spell over winter to form good bulbs, so in the UK they are generally planted in autumn. There are two main types of garlic: hardneck and softneck. Hardneck types produce flower stalks (scapes) which should be removed, and their bulbs have fewer but larger cloves (they store for around 4–6 months). Softneck types have more, smaller cloves and rarely bolt; they also store for longer, often up to a year.
Peas
A cool-season legume grown for its sweet pods or shelling peas. In the UK, peas thrive in early spring and autumn, needing support and protection from pests like mice and pigeons.
