SOWING INDOORS 1 Sow and cover

Fill a small pot with compost and sow seed thinly across the surface. Sprinkle lightly with compost, label and water with a fine rose.

2 Keep them warm

Place on a heated mat, inside a windowsill propagator or in an airing cupboard (check daily for signs of germination). You’re after 20-25C (68-77F).

3 Grow them on

Keep them warm and bright, rotating windowsill pots daily. Prick out into individual pots once they have their first true leaves.
