It is better to start harvesting it because the plants will produce full-sized heads when they are left to mature. Depending on the variety the leaves can be either red or green and also take the form of oak leaves.
  • Looseleaf: The looseleaf is one of the types of lettuce that can be grown easily. It also grows very fast as it only takes between 5 to 6 weeks to produce large loose heads.

Planting Lettuce Seeds

Lettuce is a type of crop that thrives in cool weather. Hence, the best time to grow lettuce is during spring and fall. In temperatures as low as 40 F, your lettuce seeds will germinate.

But the best temperature for growing and germination is from 60 F and 65 F. To get a successful outcome at growing lettuce, start by choosing a location that gets up to six to eight hours of sunlight. You can also grow your lettuce in a shady spot but must get three to four hours of sun.

But if there’s not enough sunlight, it will be advisable to plant looseleaf varieties. This is because they grow more quickly than the varieties that produce heads. The next thing should be to mix in one or two inches of compost in your garden bed. You may also mix in organic fertilizer with slow release.

Growing lettuce in containers is also a great idea. This is because the plant has a shallow root system. Lettuce can be grown in pots, baskets, window boxes, or fabric planters. Using any type of container that is four to six inches deep with holes for drainage is also fine.

In order to be able to harvest your crop early, get plastic or fabric-covered mini tunnels to cover your garden beds. This way, you can trap in solar energy. It can also help to protect your plants from low temperatures and frost during early spring or fall.

Methods For Planting Lettuce Seeds

Lettuce seeds can be planted in two ways. They are:

  • Direct Sowing Lettuce Seeds

This involves directly planting lettuce seeds in garden beds or containers. For direct planting of varieties of seeds of lettuce that produce heads in rows, give the seeds space of two inches apart. This should depend on the varieties you’re planting though.

Endeavor not to plant the seeds deep down in the soil, remember they need the sunlight to sprout. Go ahead and pour a little amount of soil on your seeds. You can begin thinning when your seedlings are growing well.

  • Transplanting Lettuce Seedlings

This on the other hand entails transplanting lettuce seedlings that were started indoors or bought from a garden center. You can start by transplanting your seedlings into your garden beds or containers in a grid form. Endeavor to give space of at least ten inches between each seedling.

If you’re transplanting multicolored varieties, you can bring creativity to play by arranging the colors to form a checkerboard pattern.

Remember to take note of the specific spacing instructions on the packet of the seeds you bought. Hence, if you’re transplanting in rows, depending on how mature in size of each variety is, give your seedlings space of ten to twelve inches each. And then space the rows by twelve to eighteen inches.

Spacing Your Lettuce Plants

Start thinning your lettuce seedlings once they begin to grow well. Doing this will allow the plants enough space for them to produce good-sized heads when they mature. The ideal spacing should be ten to twelve inches but you can still check the seed packet for specific spacing instructions for each variety.

If you’re growing baby lettuce, make the spacing between each plant a bit closer at about six to eight inches because of the formation of heads. Romaine lettuce can be grown successfully with this method as this type of lettuce produces tight heads.
