Are you looking to add a little greenery to your garden? Need something new next to your pumpkins and tomatoes and garlic? Lettuce (Lactuca sativa) might just be the perfect plant for you! With hundreds of varieties to choose from, this easy-to-grow annual is a classic for both beginner and expert gardeners. Plus, most types of lettuce mature in just five to eight weeks, making it a quick and satisfying addition to your garden.

You can even harvest it for cut-and-come-again salads, snipping off a few leaves whenever you like. As a cool-season vegetable, lettuce is typically planted in early spring and harvested in late spring to early summer, although some gardeners opt for a second crop in the fall.

Common Lettuce varieties:

  • Romaine
  • Iceberg
  • Kale
  • Boston
  • Looseleaf


Caring for lettuce plants is easier than you might think! The key is to keep the soil moist but not too wet, with good drainage. If your lettuce does wilt in the sun, just give it a drink right away and cool off the leaves with some water. You can also use row covers to provide some shade, and mulch to keep the roots cool as the season heats up. With a little bit of attention, your lettuce will be thriving in no time!

  • Soil: keep in mind that it prefers light soil, rich in organic matter, and drains well. In addition, it’s best to aim for a soil pH that’s neutral to slightly acidic.
  • Light: lettuce loves soaking up the sunlight. For best results, try to give it at least six hours of direct sunlight most days. But don’t worry if your garden doesn’t get quite that much sun – lettuce is pretty adaptable and can still grow in partial sun.
  • Water: keeping the soil evenly moist is key when growing lettuce. If the soil gets too dry, your plants may bolt and go to seed prematurely, resulting in bitter-tasting leaves. Plus, dry soil can cause the leaves to get sun-scorched. To avoid these problems, try watering your lettuce regularly throughout the week, whenever the top inch of soil feels dry to the touch,
  • Temperature: Lettuce is a cool-season crop that prefers growing in temperatures ranging from around 45 to 70 degrees Fahrenheit. When temperatures get too hot, lettuce leaves can turn bitter. If you’re planting in the summer, be sure to select heat-tolerant varieties.


Propagating lettuce is actually pretty easy, and it can be done by taking cuttings or simply from seeds.

To get started, you’ll need to get some lettuce cuttings. You can do this by purchasing some from your local grocery store or farmers market, and then cutting the leaves about an inch from the bottom while keeping the remaining stem intact. It’s worth noting that not all lettuce varieties are suitable for regrowing, but it’s definitely worth a try since you’ve already paid for the food!

Frequently Asked Questions

How long does it take to grow lettuce?

Lettuce is a fast-growing crop that typically matures in five to eight weeks after planting, depending on the variety. So, you can enjoy fresh, homegrown lettuce in just a few short weeks!

Does lettuce need full sun?

Lettuce prefers full sun, meaning at least six hours of direct sunlight on most days, but it can also grow in partial sun and appreciates some shade in warm climates. However, too much shade can make the growth leggy and weak, so it’s best to find a balance that works for your specific location.

Does lettuce grow back every year?

Lettuce is an annual plant, which means it completes its life cycle in one growing season. It typically does not grow back every year on its own, but you can replant lettuce each season to enjoy fresh, homegrown greens.

What is the lifespan of lettuce?

Lettuce leaves can be picked when they are large enough to use, typically about 3 to 4 inches long, depending on the variety. You can harvest lettuce anytime throughout its growing season, and it’s best to pick the outer leaves first, so the inner leaves can continue to grow for later harvests.
