How long does it take to grow lettuce?

With the right growing conditions, you can plant lettuce seeds and harvest your first leaves in less than six weeks. You can even eat your own lettuce leaves beforehand when you harvest the edible young seedlings instead of throwing them away while thinning out your plants.

Which lettuce is the easiest to grow?

You can sow lettuce seeds all year round, sow outside in spring and summer, and grow inside in winter.

Should I soak lettuce seeds before planting?

Some gardeners find that germination is more successful by soaking lettuce seeds in cold water for 16-24 hours, but this is not necessary. It is important to barely cover the seed after sowing, a very fine layer of compost is sufficient, as light is required for germination. The germination process can be accelerated in a warm greenhouse or by warming the soil with a fleece before sowing the lettuce seeds to warm them up.

How to sow lettuce seeds

If you are sowing lettuce seeds directly into the ground outdoors, prepare the soil first by digging in plenty of well-rotted garden compost. This reduces the likelihood that salads will “shoot through” (sow) in the hot summer months.

Provide moist, well-prepared soil or compost and sow the seeds thinly. Cover only with a fine layer of compost, as lettuce seeds need light to germinate. They should start to germinate after about 7 days.

Once large enough, thin the seedlings to leave a 10-20 cm gap between plants and mulch around them with well-rotted compost to retain moisture and keep them healthy. You may need to cover seedlings with fleece to protect them from birds.

Instead of sowing all the lettuce seeds at once, try reseeding – repeated sowing at intervals throughout the growing season. If you sow little and often, you won’t end up with an abundance of mature plants all ready to eat at the same time.

Garden writer and photographer Leigh Clapp favors the follow-up planting approach, saying, ‘Lettuce will yield about five months from a seed packet. Sow every two weeks for a continuous harvest. ‘

How often should salad be poured?

How often you have to water depends on how hot or dry the weather is. But the main thing is to evenly water the compost so that the lettuce seedlings do not dry out. Try not to soak the leaves as this can lead to powdery mildew. Thinning the plants to leave space between them helps air circulation and prevents mold.
