Watering:Keep the soil consistently moist but not waterlogged, as lettuce has shallow roots.
Fertilizing:Amend the soil with compost or use a balanced, nitrogen-rich fertilizer to promote healthy leafy growth.
Temperature Control:While heat-tolerant for a butterhead variety, use shade cloth during heat waves to protect plants from excessive heat and prevent bitterness or bolting.
Pest Control:The plant is relatively pest-resistant, but regular monitoring is recommended for common pests like aphids, slugs, and snails.
Harvesting
Buttercrunch lettuce typically matures in 55-65 days, but leaves can be harvested at any time once they are large enough to eat.
Cut-and-Come-Again Method:Harvest the larger, outer leaves as needed, leaving at least half of the plant and the central core intact to continue growing. This method allows for a continuous supply throughout the season.
Whole Head Harvest:Cut the entire head off at the base, about an inch or two above the crown, once it forms a dense head about 6 to 8 inches in diameter. Leaving the roots in the ground may allow for some regrowth.
Timing:Harvest in the early morning for the best, most crisp flavor.
Storage:Store harvested leaves dry in a plastic bag in the refrigerator for up to a week, away from ethylene-producing fruits like apples or bananas.
