Lettuce, Igloo

Short Description

Quick growing, excellent heat resistance too.

Full Description

Cool, crispy heads form quickly, yet hold incredibly well in the garden as the summer temperatures creep higher. Its strong heat resistance made it a marvelous performer in our Fordhook Farm kitchen garden in spring, summer and fall plantings. Fresh green color and pleasingly mild flavor just add to its winning qualities.

  • 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.
    • Folow 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 frequent during periods of drought.
    • Mulch your home garden 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, Igloo is rated 3.0 out of 5 by 2.
    Rated 5 out of 5 by from IMO, the best lettuce out there! Igloo lettuce is my family's favorite by far! We have grown many varieties of lettuce that are suppose to hold up well in high heat with not much luck. This lettuce does very well in the heat and we haven't had any bitter or off flavors even when picked during the middle of the day. We just pick a little off the outside of the head for sandwiches or just to eat plain as it grows. My kids love it and during the day they'll go to the garden and pick this lettuce with some tomatoes and eat it as a snack. I've started seeds indoors and direct sow outside with no problems at all. (Recommend hardening off before transplanting outside just like other plants.)

    Rated 1 out of 5 by from Wont buy again I bought this lettuce back in march and starting them indoors. They germinated really fast and grew to about 2in seedlings. The thing about this is that the package says to start them about 1/2in deep. So when the stems got so big they got top heavy and the stem bent over and died. I only have about 6 or so left that are good.
