How to Grow Lettuce Like a Pro

From salads to dressing BLTs, lettuce is one of the most versatile veggies out there. And as it turns out, lettuce is one of the easiest and most rewarding vegetables to grow, making it ideal for beginner and experienced gardeners alike.

According to Elin Harryson, a plant expert for Planta, "lettuce grows quickly, takes up very little space and, because many varieties mature in approximately 30 to 60 days, gardeners can enjoy multiple harvests throughout the growing season," Harryson says. "Lettuce also performs well in raised beds, containers and traditional garden rows, making it a flexible option for nearly any growing setup."

If you're a newbie to growing lettuce or want to improve your crop, read on for these helpful steps.

1. Choose the Best Growing Season

First of all, Harryson emphasizes the importance of choosing the best growing season for your region.

"Lettuce thrives in cool weather. For most regions, plant in spring and early summer and again in the fall when temperatures are mild," she says. "Hot weather can cause plants to bolt, meaning they send up flower stalks and develop a bitter flavor."

2. Growing Site Guidelines

You can grow lettuce in raised beds, containers and as in-ground plants, but there are some differences between these approaches to keep in mind.

To start, Harryson says that in general, lettuce grows best when it receives four to six hours of sunlight daily, thrives in afternoon shade in warmer climates, gets good air circulation and is planted in loose, well-draining soil.

Harryson says that raised beds are particularly excellent for lettuce because the beds "warm up quickly in spring and offer better drainage and soil control."

Containers make for great options if you have a patio or small space. "Choose containers at least six inches deep with drainage holes," Harryson advises. "Container-grown lettuce may need more frequent watering."

As for growing lettuce in in-ground gardens, Harryson says that it will perform well directly in the beds as long as the soil is loose and enriched with organic matter.

3. Soil Prep

"Lettuce prefers nutrient-rich, moisture-retentive soil with plenty of organic matter," Harryson shares. Work finished compost into the top six to eight inches of soil before planting, if needed to improve drainage. "Avoid compacted soil, which can stress young plants," she says.

4. Plant the Seeds or Seedlings

When it comes time to plant, Harryson says that you'll sow the lettuce seeds about a quarter inch deep. Additionally, you should space any seedlings according to their variety, six to 12 inches apart.

"For continuous harvests, sow a new round of seeds every two to three weeks," Harryson suggests. "Lettuce seeds germinate best in cool soil, typically between 55 and 75°F."

5. Sun and Water Needs

Harryson says that lettuce grows best in full sun during cooler weather, but part-shade can help extend the growing season once temperatures rise. Also, she stresses that consistent moisture is essential.

"Water consistently to keep the soil evenly moist but not soggy," she says. "Lettuce has shallow roots and can become bitter or bolt quickly if allowed to dry out for an extended period. Mulching around plants can help to conserve moisture and regulate soil temperature."

If you live in a warmer region, Harryson says that growing lettuce in partial shade can significantly extend the season.

"Companion planting between taller plants such as tomatoes, okra and pepper plants can provide shade for the lettuce and maximize garden space," she adds.

Troubleshooting and Common Problems

Even though growing lettuce is relatively straightforward when compared to other vegetables, there are some problems that can arise.

Firstly, there's "bolting," which is triggered by hot temperatures or inconsistent watering. To avoid this, Harryson says that you should plant lettuce early in the season: it can be planted as soon as the ground thaws and the soil is workable. Further, she recommends using a shade cloth during warm spells. Keep the soil consistently moist. Harvest lettuce regularly. And choose heat-tolerant varieties for warmer regions.

Then there are those pesky slugs and snails that can disrupt your crop, which Harryson says are attracted to tender lettuce leaves. To keep them at bay, Harryson recommends watering the lettuce in the morning rather than in the evening, remove debris where pests can hide and using physical barriers or hand-picking slugs and snails as needed.

Aphids are another pest that may infiltrate your lettuce and may cluster on the leaves. "Spray plants with water to dislodge them," Harryson says. "Plant flowers with tiny blooms that attract hoverflies and ladybugs, such as alyssum."

Harvesting Lettuce

Harryson says that lettuce can be harvested in several ways, depending on the variety and your preference.

For leaf lettuce, she says that you'll pick the outer leaves individually once they are large enough to eat, allowing the center to continue growing.

For head lettuce, she suggests harvesting the entire head when it feels firm and has reached mature size.

"Morning harvests usually provide the crispest texture and best flavor," Harryson adds.
