Heritage Lettuce
This is a really excellent crisp-leaved lettuce that grows so well in summer- it tolerates heat without bolting quickly and leaves can be harvested from the outside as you require, or you can pick the whole lettuce too.
Sow in a seed tray in spring and summer. The seeds are small and need light to germinate so should be sown thinly on the soil surface and topped with a thin layer of seed-raising mix. They'll need light, warmth (but not too hot - should be sheltered and shaded from the hotter days). Grow seedlings on for three to four weeks before planting into the garden.
Choose a sunny, sheltered spot for planting. Lettuces that will be maturing over summer appreciate a bit of shade at the hottest time of the day. Planting them on the shady side of a row of beans etc simple way to keep them cool. Protect from slugs and snails. Keep moisture levels even and liquid feed weekly with worm tea or fertiliser to avoid bitter, tough leaves.
