Firm and water the compost before sowing. Check sowing depths so you know how much space to leave at the top of the pot for covering seed. Space them evenly and cover with vermiculite, perlite or sieved compost.
Keep the pot in a well-lit postion and short, stocky seedlings should emerge. As soon as the true leaves are large enough to hold, they are ready for you to transplant. Leggy, tall seedlings are fragile and prone to damage.
Gently tap the pot so you can pull out the seedlings. Take care to handle the seedlings by their seed leaves, rather than their stems, and gently prise them apart. Pot seedlings singly.
