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

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%.

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”.

Do lettuce seeds need sunlight to germinate?

Seeds that require light to germinate are lettuce and savory. ... These seeds can germinate in light if surrounded by moist soil or they can be lightly covered with soil.

Will romaine lettuce regrow after cutting?

How do you harvest romaine lettuce without killing the plant?

Once the leaves of a loose leaf lettuce grow to at least 4 inches tall, it means that they are ready to be harvested. Closely similar to the process of harvesting romaine lettuce, snip each leaf off of the plant just above the crown. Cutting into or below the crown will definitely kill your entire plant.

How do you know when Romaine lettuce is ready to harvest?

You can tell that your lettuce is mature when it looks dark green and the leaves look open; leaves should also overlap in a tight bunch. Romaine lettuce should be harvested when it's full size, but just before it's reached maturity.

Can I grow romaine lettuce in a container?

Although a romaine lettuce can grow in containers as small as a 4-inch pot, growth is optimum in larger containers where the soil doesn't dry as fast and there's room for root growth. ... Plastic pots are easier to keep clean than clay pots, weigh less and prevent the roots from drying out too quickly.

How do you harvest lettuce so it keeps growing?

Cut the outer lettuce leaves about 1 inch above the crown. This protects the crown so the lettuce can continue growing. Cut off the amount of lettuce needed when the leaves reach a length between 3 and 6 inches. Water the lettuce regularly to encourage continued growth even after you begin harvesting.

What is the best time to grow 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 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.

How do you keep romaine lettuce from bolting?

What month do you plant lettuce seeds?

When To Plant Lettuce Seeds

Lettuce seeds germinate best in the cooler temperatures of spring or fall. If it's too hot, they won't germinate. So, the best time to plant lettuce seeds is as soon as the ground is workable in very early spring, or once the temps start to cool down in late summer or early fall.

Can you plant multiple seeds in one hole?

Don't exceed three seeds per hole. If more than one germinates, snip off extras at the soil line also. This prevents disturbance of the seedling roots on the one you'll continue growing out when thinning. Don't add more than one large seed to a hole.

What happens if seeds are planted too close together?

Plants also can affect how nearby companions grow, as roots tangle and compete for the same resources of water and nutrients in the soil. Planting too close together limits the growth potential and often threatens plant health.
