Does lettuce grow true to seed?
Before you go to the effort of saving lettuce seeds, first, make sure to save seeds only from open-pollinated or heirloom varieties. Open-pollinated and heirloom plants both grow true to seed. Open-pollinated varieties are more genetically diverse, allowing them to better adapt to specific growing conditions.
Does lettuce start from seeds?
Lettuce Sowing and Planting Tips
Lettuce is grown from seeds or transplants. Seed is viable for 5 years. Start lettuce indoors 4 weeks before transplanting; sow or transplant lettuce into the garden as soon as the soil can be worked.
Does lettuce need a lot of water?

Can lettuce be grown in pots?
Almost all varieties of lettuce can be grown in containers. But loose leaf types tend to do better and require less space than full-head varieties. Some are meant to be grown to maturity and harvested only once, while others can be picked in baby-leaf form or harvested a few leaves at a time.
Does lettuce need soil to grow?
Soil Preparation
Lettuce does best in a loose, well-drained soil, with regular watering and adequate nitrogen. Whether your soil is heavy clay or a light sandy type, the incorporation of compost will often improve the growing conditions.
Will lettuce grow roots in water?

The most modern and innovative method of growing lettuce is on water! Growing the lettuce plants in open ground is no longer necessary. The lettuce also receives all the right nutrients through the water.
Does lettuce grow in hot weather?
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.
Can lettuce grow in hot temperatures?
Lettuce grows best in a temperature range of about 45 to 75 degrees. In weather hotter than that, the leaves become bitter to the taste. When leaf lettuce bolts—which means they begin to send up its flower shoots—it’s a signal that the production of edible lettuce is done for the season.
What temp kills lettuce?
Lettuce may cope with light freezing and even one or two hard freezes, but once the thermometer reads 25°F or below, the plants are in danger.
How does lettuce reproduce?
If a lettuce plant is allowed to reach maturity, it will grow a central reproductive shoot that springs up and produces a cluster of little flowers. The flowers self-pollinate and wilt. In their place grows little parachutes called pappus. Each of the parachutes is attached to several lettuce seeds.
Can you save seed from lettuce?
