Lactuca sativa 'Buttercrunch'
vegetableButtercrunch is a popular butterhead lettuce forming a loose rosette of soft, buttery green leaves around a tender, blanched heart, with a sweet, mild flavor and a crisp center. An award-winning variety prized for tolerating heat better than most butterheads, it is slower to bolt and turn bitter, and it matures in about 55 to 65 days.

When to Fertilize
About 3 weeks after transplant
Fertilizer
Nitrogen-rich (blood meal or 21-0-0)
Direct sow or transplant in cool weather, spacing plants about 7 to 8 inches apart in fertile, moist soil, and sow small batches every couple of weeks for a steady supply. Keep the soil evenly moist and give afternoon shade in warm weather; although Buttercrunch resists bolting, heat above about 80F eventually pushes it to flower and turn bitter.

Proactive ways to stop trouble before it starts — tap a name with an arrow for its full guide
Interplant alyssum and herbs to draw hoverflies and lacewings; inspect leaf undersides
Water in the morning so beds dry by night; set traps; hand-pick after dark
Use row cover over seedlings
Pick outer leaves as needed cut-and-come-again, or cut the whole head at the base once it has formed a full, loose rosette, harvesting in the cool of the morning. Harvest before the plant sends up a flower stalk, after which the leaves turn bitter and the sap milky.
Butterhead lettuce is very low in calories and a good source of vitamins A and K, with folate and small amounts of vitamin C, and its tender leaves are more nutritious than crisphead types.
