Lettuce needs to grow quickly for best quality. This can only be done by giving the plants everything they need. Does best when planted in early spring or late summer. The young plants are vulnerable to weeds, so keep well weeded. Their roots are shallow so be careful with the hoe. Does best when planted in early spring or late summer. Lettuce likes full sun except in hot summer climates where it prefers some shade, especially in the afternoon. Add plenty of compost to the soil to encourage rapid growth. Water evenly and moderately to prevent bitterness.

Lettuce is largely composed of water and it responds to irrigation by giving a larger and better tasting harvest. If you think the plants might need water they probably do.
Lettuce has a weak root system and isn't a very efficient feeder, so the soil needs to be quite fertile. Its main requirement is for nitrogen, but it also needs moderate amounts of potassium and phosphorus.
