Cover seeds thinly with fine, sieved compost, or use a layer of vermiculite, a sterile material perfect for covering seeds.

Germination rates vary between varieties. Wait until the seedlings are well developed with good roots before pricking out.

The secret of germinating summer bedding seeds is a plentiful supply of warmth and light.

Handle seedlings by their first leaves to avoid crushing the stem and plant individually into pots of seed compost.

By late May or early June, late frosts should have passed and outdoor conditions will be warm enough to plant your bedding into their final position outside for a bright summer display.

Water seedlings regularly in order to avoid compost drying out and after 4-6 weeks add a weekly liquid feed using a general fertiliser to promote strong and healthy growth.
