Does lettuce need direct sunlight?

Check the soil moisture daily and water as needed. Depending on the type of lettuce planted, seeds will begin to sprout in 7 to 14 days.

Can lettuce grow in indirect sunlight?

Salad greens such as lettuce, spinach, cabbage, and celery can be grown in shaded gardens. Roots crops such as beets, leeks, potatoes, and turnips can be grown in shady gardens.

What causes Tipburn in lettuce?

Too much or too little water can spell disaster for lettuce plants at every stage of growth. Insufficient moisture will cause lettuce seeds and seedlings to fail, while too much water will contribute to fungal and bacterial growth that can kill young seedlings.

Does lettuce like lots of water?

Water your lettuce plants every day—and even more often if it is extremely hot and dry. The lettuce leaves are mostly water and will desiccate and wilt in strong sunlight and dry soil. Lettuce roots tend to be shallow, so frequent watering is more important than deep watering.
