Lettuce grows fairly quickly. Leaf varieties reach maturity in 30 days but can be harvested as soon as they reach the desired size. Other types of lettuce require 6 to 8 weeks to reach full harvest size.
How long will lettuce keep producing?
Lettuce plants will continue to produce new leaves until the plant begins to flower and make new seeds. When mature plants begin to set lettuce seed like this it is called “bolting” in gardening circles. When you see this happening — a sturdy seed stalk will emerge from the center of the plant — stop harvesting.
Does lettuce continuously grow?
It can be grown in almost any location in the garden – straight in the soil, on the windowsill, or even between your flowers. With a good focus on gardening basics like proper water, shade, and planting in succession, lettuce can be a constant harvest from your garden almost the entire year long.

As long as you’re staying within lettuce’s optimal growing conditions, you can harvest from each lettuce plant at least three or four times in a season using the cut-and-come-again method, and about two to three times using the ponytail chop method (but you’ll get more leaves with each harvest this way).
How long can you cut and come again lettuce?
Cut and Come Again Lettuce Mixes are perfect for Baby Greens. The first harvest begins in about 21 to 28 days. After the initial “cut”, the new lettuces will begin growing. Watch for them to be ready in about 2 weeks for small leaf lettuce or 3 weeks for larger leaves.
What is the life cycle of lettuce?
total life cycle for lettuce is 48 days from the seed to harvest. Germination takes place in the germination rooms under germination specific conditions (see Table 5-1). The seedlings then spend 14 days in the nurseries before they are transplanted out into the main gutter growth system.
Can you eat lettuce once it has bolted?
In theory, bolted lettuce is still edible and non-toxic, however a taste test is always a good idea. The leaves tend to become tougher, more bitter and may not be enjoyable. The plant builds up bitter substances to make them less appetising for predators.
How do you grow a constant supply of lettuce?
To harvest high-quality salad greens almost every month of the year, you need to maintain a ready supply of young transplants. The only way to do it is to sow a pinch or two of seeds every week, either indoors or out. Start seeds indoors when it’s either too cold or too hot outdoors.
Does lettuce grow back every year?

Should I cut the flowers off my lettuce?
So you can cut it back and hope for another crop. Although most lettuce is so quick to sprout and grow, I usually prefer to just replant once it’s flowered out. You can also let the bolted lettuce flower out and then keep it in your garden to attract beneficial insects and pollinators.
Why is my lettuce growing so tall?
ANSWER: Lettuce plants that suddenly start stretching toward the sky and growing extra tall are likely to be bolting. In the bolting stage, a plant stops focusing so much on producing foliage and starts to turn its attention toward reproduction, sending out a flower stalk that will eventually dry to release seeds.
What is the white stuff coming out of my lettuce?
The white sap is a milky fluid made of latex that’s naturally found in the lettuce and is completely harmless. The botanical name for the substance is lactucarium, which comes from lactus, the Latin word for milk (the botanical name for lettuce is lactuca sativa, which also stems from this word).

How do I stop my lettuce from bolting?
Give your lettuce a break from full sun. Grow pots of lettuce on a porch or patio that gets some shade, plant it in the garden under taller plants, like corn, or use a shade cloth over your lettuce bed. Regular watering can also help delay bolting.
