When to plant lettuce seed?

What month do you 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). To grow great lettuce, find a site that offers at least six to eight hours of direct sun.

How early can you plant lettuce outside?

Lettuce grows best in cool weather in the spring and fall. Sow in April every 2-3 weeks for a continual harvest. Using a cloche, cold frame, or greenhouse over mid-late August plantings can extend the harvest period right into winter. Optimal soil temperature for germination: 10-22°C (50-72°F).

How do you grow lettuce from seed?

Cover seeds thinly with soil or vermiculite (they germinate better with some light). Leave 30cm between rows. If sowing in pots, scatter seed sparingly over the surface of moist, peat-free seed compost and cover with a fine layer of compost or vermiculite.

When should I plant fall lettuce seeds?

August is the time to sow seeds directly into the garden or pots for a fall leaf lettuce crop. Frilly, leafy lettuces are as decorative growing as they are in a salad bowl or on a BLT.

Does lettuce need full sun?

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. Give lettuce fertile, well-drained, moist soil with plenty of rich organic matter and a pH between 6.0 and 7.0.

How do you harvest lettuce so it keeps growing?

Why are my lettuce seeds not germinating?

Lettuce seeds won’t sprout when soil temperatures are above 80°F but they will start to germinate as low as 40°F, making it ideal for early and late season planting. A plant hormone is produced under warm conditions that stop the germination process, called “thermo-inhibition”.

How often should Lettuce be watered?

Water your lettuce plants every day—and even more often if it is extremely hot and dry. The lettuce leaves are mostly water and will desiccate and wilt in strong sunlight and dry soil. Lettuce roots tend to be shallow, so frequent watering is more important than deep watering.

Will lettuce regrow after cutting?

Head lettuce will die back, but most leaf-lettuce plants renew efforts to produce leaves, if regularly watered after trimming. Results will often be smaller than the original plant, but you may be able to harvest a second, good-tasting crop within as little as two weeks.

Should I soak lettuce seeds before planting?

Imbibing or soaking the seeds in cool water for 16–24 hours in a well-lit area before planting will increase the germination percentages greatly.

How many lettuce seeds do you plant in one hole?

Lettuce. Germination rates are around 80%, so anywhere from 1 to 3 seeds are often planted per hole. Plant at least two to guarantee a high per-hole germination rate of 96%.
