Lettuce should be planted at least 12 inches apart.  There’s a good reason why you don’t grow lettuce close together because of pests. Pests love to eat lettuce, and they have their favorite spots to lay eggs. When they’re close together, the lettuce leaves will touch each other. When they touch each other, they form a web of lettuce that is perfect for bugs to crawl into.

The best spacing for lettuce is 12 inches, but most growers don’t get this. They grow it in rows that are 2 to 4 feet apart. This means that the plants are very crowded and can’t put out as many leaves. Lettuce plants need plenty of room to spread out and grow. If you live in a hot climate, you should plant lettuce at least a foot away from the house, or you may have a problem with mildew.

Lettuce is an easy-to-grow vegetable that thrives in loose well-drained soils. It is a cool-season crop and will be available from early to late spring and fall. Lettuce is available in many different varieties, colors, shapes, and flavors.  To grow healthy lettuce heads, it is important to consider the following

Location

Lettuce loves the sun, but should not be planted under a very strong sun. Provide it with at least 6 hours of sun and partial shade to balance it out.

Soil Type

Lettuce is a cool-season crop and prefers well-drained loam or clay soils.  It will do fine in sandy soil, but the leaves will be smaller.  If your soil is sandy, you will need to add lots of compost to help improve the soil structure.  Lettuce will also grow well in very heavy clay soils.  It needs loose, friable, well-drained soil with lots of organic matter.  Add compost or manure before planting.

Spacing

How far apart do you plant lettuce.  Allow at least 12 inches between plants and rows to give them maximum space to thrive and grow big heads.

Watering

Fertilizing – How Far Apart Do You Plant Lettuce

Lettuce is an annual vegetable that will grow best when fed a balanced fertilizer.  A balanced fertilizer provides the nutrients needed by the plant.  A fertilizer high in Nitrogen (N) will encourage thick leaf growth and may make the leaves tough.  A fertilizer high in Phosphorus (P) will encourage bushy growth but will make the leaves bitter tasting.

Pests

The main pests that attack lettuce are aphids, mites, and leafhoppers.  Aphids are small green or brown insects with soft bodies.  They can cause stunted growth and yellowing of the leaves.  Use a strong spray of water to control aphids.  Mites cause small circular holes in the leaves. Remove mites with a strong blast of air from a garden hose.  Leafhoppers can be controlled by handpicking and disposing of them.

Diseases

Powdery mildew is a fungal disease that affects lettuce.  It appears as white powder on the leaves.  The powdery mildew fungus can grow quickly.  It can also be very difficult to get rid of because it can remain on the leaves for many weeks after the plant dies.  To prevent powdery mildew, keep the soil moist.  This will encourage new growth.  Cut back on watering in the heat of the day.  When the plant has two or three sets of true leaves, you should be able to see if there is a problem.  If powdery mildew is a problem, use a fungicide.  Be sure to follow the directions on the label.

Pollination – How Far Apart Do You Plant Lettuce

Lettuce needs to be pollinated by bees and other insects.  Without pollination, the flowers will not produce seeds.  To attract pollinators, provide nectar sources such as clover, alfalfa, sunflower, and daisies if you want to harvest seeds from flowered lettuce.

Harvesting

Lettuce is usually harvested when it reaches maturity.  The best time to harvest lettuce is when the heads have just formed.  When the heads are cut, the individual leaves will not need to be separated.  To help prevent the lettuce from turning brown after harvesting, cut the heads into quarters or eighths before storing them.  Store them in a cold place.
