Plant family

Lettuce is in the daisy family, also called the aster family. Other crops in this broad family include endive, escarole, artichoke, and sunflower, though home garden rotation usually focuses more on lettuce and salad greens.

Why rotate lettuce

Lettuce can leave behind diseases such as bottom rot and drop, especially in cool, damp conditions. It has a modest nutrient demand compared with fruiting crops, but frequent succession planting can still stress a bed over time. Repeated plantings in one place also increase the chance that soilborne disease organisms persist. Rotation helps spread out these risks and keeps salad beds productive.

What to plant after

Lettuce grows well after heavier feeding summer crops if compost was added previously and the soil surface is clean. It is also a good crop to follow peas, beans, onions, or early potatoes when you want a quick cool-season planting.

What to avoid

Avoid planting lettuce immediately after another long run of lettuce or related salad crops if you have seen rot problems. Also avoid putting it into a bed with fresh residues from diseased plants that can keep the soil surface damp and contaminated.

Example rotation

One rotation is tomatoes in summer, then fall lettuce, then spring peas the next year. Another is onions, then lettuce, followed by beans or carrots.

Tips

Use lettuce as a flexible bridge crop in your rotation because it matures quickly and can fit between larger seasonal crops. Keep residues cleaned up and avoid crowding plantings where leaf and soil diseases have shown up.
