Sow indoors from April on. Use seedtrays filled with moist potting soil. Sow shallow and thin. Press the seeds gently on to the soil, but don't cover them. Basil is a light germinator. Use a spray bottle to water the seeds, so you don't disturb them. Cover the trays with a lid to retain the moisture. Keep the temperature as even as possible and don't let the temperature drop during the night.
Remove the lid when the seedlings emerge. Transplant the seedlings, when they're large enough to handle, to seperate pots.

Plant them after this period on a very sunny and sheltered plot, from the middle of May, when there's no longer any danger of nightfrosts. Keep the plants 20 - 25 cm apart.
