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 4.1 out of 5 by 34.
Rated 5 out of 5 by from Fast growing Harvested my first salad only 38 days after sowing seed. Tender and delicious when leaves are 6-8 inches.

Rated 4 out of 5 by from Takes the South Dakota temps like a champ You wouldn't think it gets that hot in the Dakotas if you've read Laura Ingalls Wilder, but trust me--it does. I've been buying this lettuce blend for years and it takes the heat like a champ. Only in one year did it fail to produce, and I had practically NO lettuce that year, of any kind. Only thing is it can be somewhat bitter, no matter what time of day you cut it. I suppose if I cut it before sunrise it would be better, but I'm just not up that early. So you may want to mix it with a different type to balance it out. Just keep it trimmed, don't let it bolt, and you'll be happy with it.

Rated 1 out of 5 by from Disappointing I bought three different lettuce seeds for fall planting here in coastal South Carolina. I have done this for years. None of the seeds germinated in any of the varieties. I don't usually buy Burpee seeds and probably will not again.

Rated 2 out of 5 by from Didn't grow I planted twice, they didn't seem to grow at all. I didn't get any lettuce. They stumped in growth and then went to seed.

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.
