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.

This lettuce is an heirloom and comes up each year without any flaws. The taste is great and is a very hearty variety.Date published: 2014-08-29Rated 4 out of 5 by daisygurl from Love this lettuce! Here in Central Florida, lettuce can be tricky due to humidity and heat setting in early. This lettuce did not disappoint. It was tender and crunchy and almost sweet when picked young. I will definitely be growing it again!Date published: 2012-05-15Rated 4 out of 5 by Jasman from Very Pleased We have a small garden so we only planted a little bit (maybe a 6 foot row). About every other day I would pick some leaves off to make two salads and it always seemed like there was just as much every time I came back. The leaves were tender but not uninteresting like other lettuce I've grown before.Date published: 2011-07-13Rated 5 out of 5 by GardenGirl88 from We were able to feed the masses! We planted about 20 feet of this in a row, and it performed better than we could have hoped for. My mom and her boyfriend ate as much as they could, shared with the people in their apartment building, and there was still enough to take up to the local assisted living facility in our small town. It starts easily and quickly, and grew about 18 inches wide and high. We planted Mother's Day weekend, and it finally bolted around the beginning of August. We got a very long season for our area. Only down thing was that it did aggravate Mom's boyfriend's diverticulitis in large quantities (they ate it every day). No such trouble with the romaine.Date published: 2009-08-26Rated 4 out of 5 by lexgardener from Very easy to grow. I agree that it gets bitter the bigger it gets.Date published: 2009-03-17Rated 3 out of 5 by Ernie from Okay Purchase This is the one and only leaf lettuce that I grow. It is easy to germinate and never leaves me dissapointed. The only bad thing about the lettuce is that where I live in Maryland the lettuce is very quick to bolt and gets bitter very quickly.Date published: 2008-07-03Rated 5 out of 5 by TomatoBug from Best lettuce!! I have grown this variety several times, and have never been disappointed. The climate varies in Upstate NY, but this never seemed to affect the production. The taste is wonderful, buttery, and great on a sandwich. This lettuce also makes a fine salad.Date published: 2008-02-02
