This is called the bolting of lettuce plants. You can avoid this by giving them some shade using clothes or grow them at a partially shady place. Fertilizing And Mulching. If your soil is fertile, you don’t have to give them any kind of fertilizer. If not, you may have to fertilize them after some time. Use organic fertilizers or use some kind of manure to give them nutrients. Use any kind of fertilizer you wanted to use. Just remember, too much nitrogen can also make the leaves bitter.
