How to Sow

  • Sow lettuce seeds in average soil in full sun in early spring for first crop. Sow in late summer for fall crop.
  • Sow every two weeks to extend harvests.
  • In late summer, sow in a protected are that stays below 75 degrees F.
  • Sow thinly in rows 12 inches apart and cover with ¼ inch of fine soil.
  • Follow the spacing recommended on the seed packet for specific varieties.
  • Firm lightly and keep evenly moist.
  • Seedlings emerge in 7-10 days.

How to Grow

  • Thin to stand 8 inches apart when seedlings are 1-2 inches tall.
  • Keep lettuce plants well watered during dry periods to promote rapid, uninterrupted growth.
  • Lettuce is shallow-rooted, so avoid disturbing the soil around the plants when weeding.
  • Unless there is regular rainfall, lettuce plants must be watered deeply at least once a week and more frequently during periods of drought.
  • Mulch with a layer of compost or clean straw to help the soil retain moisture.

Harvest and Preserving Tips

  • For the best quality, pick lettuce early rather than late as lettuce allowed to grow too long may be bitter and tough.
  • Try to harvest in the morning when the leaves are crisp, sweet, and full of moisture.
  • Harvest looseleaf types anytime the leaves are large enough to use.
  • Harvest butterhead types when they have formed heads and the leaves are a good size.
  • Cut the heads below the crown.
  • On leaf types, you can just pick a few leaves at a time, if you like.
  • Store for 5-7 days in a plastic bag in the refrigerator. Many gardeners wrap leaves in moist paper towels.
  • Lettuce is a classic ingredient in salads. It adds crispness to sandwiches and can be used as a garnish, braised, or added to soups. Many of the looseleaf cultivars are also decorative in the garden.

Lettuce, Heatwave Blend is rated 4.275862068965517 out of 5 by 29.
Rated 4 out of 5 by from Fast-growing and reliable This is my third year ordering the heatwave blend. With the different varieties, we have lettuce well into warmer weather and then replant for fall. It's reliable, durable and produces plenty of lettuce for two people, plus neighbors.

Rated 4 out of 5 by from Still going strong! Planted in late fall and now I'm harvesting daily for salads. Only disappointment was that only one variety germinated, but I still ordered more to plant in the spring and give it another go.

Rated 5 out of 5 by from Great lettuce We live in a very hot area, but if planted correctly this lettuce will just keep producing. We would cut it regularly and it would just keep growing back and producing more and more. It was awesome and I will be purchasing it again.

Rated 1 out of 5 by from Will not grow these again. This lettuce was weedy, and did not have any taste! It shows different varieties in the picture that will grow, but I only had one kind, weeds! Very disappointed.

Rated 5 out of 5 by from great producer We planted these as a single planting in March and were still harvesting lettuce in early August. Delicious, great variety, and it doesn't wilt even in the heat.

Rated 5 out of 5 by from Great Lettuce This lettuce germinated great, and kept giving tasty lettuce through summer. Has both fancier lettuce for salads, and more plain lettuce for burgers.

Rated 4 out of 5 by from Really great blend I plant a small patch (3' x 1') of this every year. We just cut and let it regrow all through spring, summer, and fall. I have never had a bolting problem and we get far more lettuce than we can eat each week so our neighbors love it too! I do wish it had a larger % of red lettuce but still a delicious and hardy mix.

Rated 3 out of 5 by from Trade Offs This lettuce will keep on coming no matter how hot it gets outside. If raised as a cut and come again lettuce it will was sweet as can be. If you try to let it grow taller than about 12" for a nice head formation, it turns bitter. For a dead of summer lettuce, that is a trade off I can take.
