Buttercrunch LettuceWrite a review
Light requirements Full sun to part shade. Protect plants from strong spring or afternoon sun in warmest regions.
Planting Space 6 to 18 inches apart, depending on lettuce type. (Read the stick tag that comes with the plant for specific spacing recommendations.)
Soil requirements Lettuce needs moist but well-drained, nutrient-rich soil. Amend soil with compost, blood meal or other organic matter prior to planting. Fertile soil helps fuel fast, tender leaf development. Soil pH should be 6 to 7.
Water requirements Keep soil consistently moist throughout the growing season — that is the key to tender leaves. Mulch soil to reduce water evaporation and keep lettuce clean from splashing soil.
Frost-fighting plan Lettuce thrives in cold weather—established plants tolerate light frost (28 to 33ºF), and some types even withstand lower temperatures. Frost sweetens leaf flavor. It’s a good idea to protect newly planted seedlings from late spring or early fall frosts by covering plants with a frost blanket.
Common issues Pests to watch out for include aphids, slugs, and small green caterpillars.
Various fungi can attack leaves during rainy weather. Once flowers begin to form, leaf flavor becomes bitter; harvest remaining leaves immediately.
Harvesting Harvest leaves as soon as they’re large enough to eat. Pick baby leaves for salads, or wait for maturity. To extend the harvest, pick outer leaves first and allow center leaves to enlarge. For leaf lettuces, consider using a cut-and-come-again method. Cut the entire plant at the base, leaving a short stub to resprout. If harvesting frosted or frozen lettuce, allow leaves to thaw out before picking.
Storage Refrigerate unwashed leaves wrapped in dry paper towels in a loosely closed plastic bag. Leaves store from 5 to 10 days, depending on type.

The thick sweet leaves of buttercrunch lettuce add a good dose of fiber, vitamin A, vitamin K, and folate to the diet. The high water content (about 95%) and low-calorie count make this and all lettuces a healthy diet choice, with the darker and greener lettuces carrying more nutrients than the lighter colored ones. Vitamin K, found in a healthy amount in buttercrunch, has been found to play an important role in bone health, and is thought to reduce the incidence of hip fractures.
