Start lettuce indoors 4 weeks before transplanting; sow or transplant lettuce into the garden as soon as the soil can be worked. Seed germinates in 2 to 10 days at or near 70°F (21°C)—but sometimes seed can take up to 2 weeks to germinate if the soil is cold.
Is it better to start lettuce indoors?
To grow lettuce in containers, use quality outdoor potting mix. (Garden soil is heavier than potting soil, and will not drain adequately in a pot.) For a jumpstart on the spring garden, start lettuce seeds indoors 3 to 4 weeks before your area’s last hard frost — which is around 28 degrees overnight.
What is the best month to plant lettuce?
Lettuce is a cool weather crop and is best grown in spring and fall. The seeds germinate in temperatures as low as 40 F (4 C) but its ideal germination and growing temperature is between 60 and 65 F (16 to 18 C).
When should I start lettuce?
Considered a spring and fall crop, lettuce thrives when temperatures are between 60 to 70 degrees F. Many varieties reach maturity in as little as 30 days, and some can even be harvested much earlier as microgreens.
When should I start lettuce seeds?
Sow seeds in the ground 2 to 4 weeks before your last spring frost date or as soon as the ground can be worked. Or, to get a head start, start seeds indoors about 1 month before your last spring frost date. Harden off seedlings for 3 days to a week before setting outdoors.
What temperature can lettuce tolerate?
Lettuce is adapted to cool growing conditions with the optimum temperatures for growth of 60 to 65°F. At 70 to 80°F, the plants flower and produce seed. Lettuce can tolerate a few days of temperatures from 80 to 85°F, provided that nights are cool.
Should I soak lettuce seeds before planting?
To germinate lettuce seeds faster, try soaking them for 12-24 hours before planting. Also, keep the soil cool, and give them plenty of light right from the start.
Can you start head lettuce indoors?
Growing lettuce indoors is a great way to garden from the comfort of your own home. Whether you want to grow a head of lettuce or one of those loose-leaf varieties, these plants are a great way to try your hand at indoor gardening. And you’ll have a salad bowl full of fresh greens when you’re done.
Can you grow lettuce in potting soil?
Grow Lettuce and Salad Greens In Bags Of Potting Soil
No need for pots or window boxes! Lettuce is a quick and easy crop that won’t last forever so there is no need for a very deep container or garden bed. A bag of potting soil supplies enough growing space for this crop.
How often do you water lettuce seedlings?
Lettuce has shallow roots, so plants need consistent watering. Check at least twice a week and water if the soil is dry down to 1 inch deep. Containers of lettuce need to be watered more frequently than garden beds, especially in the summer.
Does lettuce need sun or shade?
full sun
Soil, Planting, and Care
Although lettuce grows fastest in full sun, it is one of the few vegetables that tolerates some shade. In fact, a spring crop often lasts longer if shaded from the afternoon sun as the season warms. You can grow lots of lettuce in a small space, even a container.
How many lettuce seeds are in a hole?
Lettuce has a high germination rate and planting between 2-3 lettuce seeds per cell or hole would be the best option. Planting 1 seed per hole can be risky in case it doesn’t germinate. Afterward, select the best seedling to use in your garden and nip the others to make sure only a single head will grow in the hole.
Does lettuce come back every year?
Lettuce regrows once its leaves have been cut or picked off the main stem. As long as the root is intact in the ground and there are at least 1-2 inches of stem and leaves at the base, lettuce will shoot new growth in as little as a week. The cut-and-come-again harvesting method is the most popular.
Which lettuce is easiest to grow?
Loose leaf lettuce, which refers to varieties that don’t form any type of head, is considered the easiest to grow. It matures in 40-45 days, but no need to wait that long to enjoy it!
How long does it take lettuce seeds to sprout?
about seven days
They must be sown very shallowly or they won’t come up as they need light to germinate. Use good potting soil from your garden supplier in your tray or pot, not soil out of your back yard, and water them gently after sowing. Keep them moist but not wet and they will emerge in about seven days.
Does lettuce germinate in the dark?
Light is required for some lettuce seeds to grow. When seeds fail to germinate in the dark, they’re called “photosensitive” or “photodormant.” Once they do emerge, to grow a field of lettuce with heads that are all relatively the same size (uniform), the seedlings must all spend an equal amount of time in the sun.
How many days does lettuce take to germinate?
7-15 days
Optimal soil temperature for germination: 10-22°C (50-72°F). Seeds should sprout in 7-15 days, depending on conditions. Lettuce seeds don’t sprout easily when the soil temperature is over 22°C (72°F) in summer.
Is 40 degrees 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.
Does lettuce need warmth to germinate?
Depending on its variety, lettuce seed can germinate when the soil temperature is 35 to 80 degrees Fahrenheit. The ideal soil temperature for germination though, is 70 to 75 F. In cooler temperatures, germination takes longer. When temperatures are warmer than 70 to 75 F, lettuce seed may not germinate.
Does lettuce need cold stratification?
Lettuce seed, which goes dormant at higher temperatures, takes to stratification. Some tree seed, including maple, walnut, and apple, require some kind of stratification. Many perennial herb seeds do better after getting the cold, stratification treatment.
Can you use egg cartons to start seeds?
You can use egg cartons as a seed-starting tray! Depending on the type of carton you have, you can even cut apart the individual sections and plant them, as the carton will biodegrade. Be sure to poke small holes for drainage, and put the cartons on a tray or in a shallow pan to catch any residual water.
