For earlier crops, start plants off indoors by sowing two seeds per 9cm pot in seed compost. Remove the weaker seedling after germination and harden off before transplanting in the garden.
Keep plants well-watered, especially in hot and dry conditions. Water in the early morning.
Cut and come again salad leaves can be harvested as required when the leaves are roughly finger-length. Lettuce plants should be harvested when the heart is firm. Test by pressing the top of the plant gently with your hand, rather than squeezing. Cut the plants at the base rather than pulling up.
