Description

(Lactuca sativa) Bibb/Butterhead. Buttercrunch set the standard for classic butterhead type lettuce for many years. Soft, buttery-textured leaves enclose a crisp, juicy, loose inner head of blanched, sweet-tasting leaves. Very heat tolerant and slow to bolt, Buttercrunch stays mild long after others have turned bitter. Developed by George Raleigh, Cornell University, and an All America Selection for 1963.

Growing Tips: Buttercrunch lettuce grows well in cool weather, ideally between 60-80 F, making it perfect for early spring or fall planting. This variety prefers moist, fertile soil rich in organic matter. However, avoid waterlogged conditions as this can lead to root rot. If you're in a hot region, provide partial shade to prevent the leaves from burning. Common pests include aphids, slugs, and snails, so regular monitoring and appropriate pest control measures are recommended.

When to Grow

Buttercrunch lettuce is best planted as a spring or fall crop in most areas. If necessary, you can start seeds indoors 4-6 weeks before the last expected frost date or directly sow them outdoors 2-4 weeks before the last frost. This lettuce does best in USDA Hardiness Zones 4-9. For specific planting times, check average local frost dates​.

How to Sow and Plant

When starting Buttercrunch lettuce indoors, sow seeds about 1/4 inch deep in seed trays filled with a quality seed-starting mix. After germination, which takes about 7-10 days, thin seedlings to about 8 inches apart when transplanting outdoors. If direct sowing, plant seeds 1/4 inch deep in well-prepared soil. Sow in thick bands for baby greens or space farther apart for head lettuce.

How to Grow

Buttercrunch lettuce requires full sun to partial shade. Ensure the soil remains consistently moist but not waterlogged, aiming for about 1-2 inches of water per week. Mulching can help retain moisture and regulate soil temperature. Fertilize with a balanced, nitrogen-rich fertilizer if needed, but healthy, fertile soil often requires no additional feeding. Watch for signs of bolting, which can occur in high temperatures, and use shade cloths or row covers to protect plants from excessive heat and pests. Regularly remove any yellowing or rotting leaves to keep the plants healthy.

How to Save Seeds

  • Lettuce is a self-pollinating annual, making it an easy crop for seed saving.
  • Choose the best and healthiest plants and allow them to send up flower stalks.
  • Once seed heads are dried and have turned a yellowish-tan color, cut the entire stalk and place in a bag.
  • Crush the seed heads in the bag and separate the chaff.
  • Store in an airtight container in the refrigerator for up to 4 years.
