Lettuce is considered “hard frost hardy,” which means it can withstand frosts below 28 degrees. If the frost continues unabated, however, the cell walls may form ice, and the plant actually freezes.
What temperature will kill vegetables?
Light freeze – 29° to 32° Fahrenheit will kill tender plants. Moderate freeze – 25° to 28° Fahrenheit is widely destructive to most vegetation. Severe or hard freeze – 25° Fahrenheit and colder causes heavy damage to most plants.
How often should Lettuce be watered?
The key to lettuce production is supplying moderate but almost constant water, especially during hot weather. Unless there is regular rainfall, lettuce must be watered deeply at least once a week- more frequently during periods of drought. Mulch with a layer of compost or clean straw to help the soil retain moisture.
What temperature is too cold for lettuce?
How to Grow: Lettuce is a cool-weather crop that thrives in the temperature range 60-65 degrees F, and if thoroughly hardened, most varieties survive temperatures as low as 20 degrees F. Cold-adapted varieties survive much lower temperatures. Seed germinates best at about 75 degrees F.
What is the best month to plant lettuce?

Does lettuce need full sun?

Why is my lettuce growing tall?
Most lettuce varieties are cool season crops. When the hot weather comes, they send up tall stalks that will flower and set seed. You’ll notice that the leaves begin to taste bitter around the same time the stalks elongate. This is called bolting.
