Can lettuce grow in indirect sunlight?

Leafy greens, such as lettuce, chard, kale, and mustards, actually prefer a little shade from harsh all-day sun. A slight dapple or a wash of indirect light offers relief from soaring summer temperatures, which often cause leafy greens to bolt (in other words, to flower and set seed) early.

How hot is too hot for lettuce?

Lettuce is a cool-season vegetable, meaning it grows best in temperatures around 60 – 65°F. Once temperatures rise above 80°F, lettuce will normally start to “bolt” or stop leaf production and send up a stalk to flower and produce seed. The leaves become bitter at this stage.

Yellow leaves can be a sign of both overwatering and underwatering (ugh!), so this diagnostic is a bit tricky.

What is the best month to plant lettuce?

How do you make lettuce grow faster?

Why is my lettuce growing so slow?

Insufficient soil moisture or overly wet soil can both result in poor growth and wilting. Lettuce suffering from drought stress wilts quickly and fails to put on new growth. Wet and soggy soil causes the plant's roots to drown and rot. Leaves may begin to yellow and wilt, or the whole plant may become stunted.
