300+ Organic Buttercrunch Lettuce Seeds- Non GMO- Lactuca Sativa--A067

Description:

Buttercrunch Lettuce is a medium green, long standing variety. The crisp, thick leaves are sweet and tender and free from any hint of bitterness. Hidden within the enticing outer leaves is the beautiful “buttery heart”. Buttercrunch butterhead lettuce seeds are a Bibb type lettuce that forms a tight little rosette of soft, dark-green, upward-facing leaves surrounding a tender, pale centre. The small hearts don't become bitter in hot weather. Later plantings stand well into fall and make good growth in spring cold frames. Buttercrunch lettuce is a good candidate for growing all winter if you can provide cloche or greenhouse protection, or even a simple cold frame.. Matures in 67 days. (Open-pollinated seeds)

Latin Lactuca sativa

Exposure: Full sun to partial shade

Zone: 4-12

Timing Lettuce grows best in cool weather in the spring and fall. Sow in April every 2-3 weeks for a continual harvest. Using a cloche, cold frame, or greenhouse over mid-late August plantings can extend the harvest period right into winter. Optimal soil temperature for germination: 10-22°C (50-72°F). Seeds should sprout in 7-15 days, depending on conditions. Seeds don’t sprout easily when the soil temperature is over 22°C (72°F) in summer. Get around this by sprouting them indoors in a cool area, or pre-sprout by sprinkling seeds on a damp paper towl and placing it in a plastic bag in the fridge for a few days. In hot weather lettuce goes to seed rapidly, so have new plantings ready to go.

Starting Direct sow or start indoors and transplant. Sow seeds 5mm (¼”) deep, or on the surface of the soil where the soil can be kept evenly moist.. Space or thin heading lettuce to 30cm (12″) apart. Space or thin looseleaf varieties to 20-25cm (8-10″) apart. Space rows for all types 45-90cm (18-36″) apart. Babyleaf lettuce can be planted quite densely, as it is harvested at an immature size. Sowing babyleaf lettuce seeds closely together in narrow rows makes harvesting simpler.

Growing Ideal pH: 6.0-6.5. Aim for a soil with ample drainage and lots of organic matter. Add compost and lime at least 3 weeks prior to planting. 1 cup of complete organic fertilizer per 3m (10′) of row will give adequate nutrition. Seedlings should be hardened off by reducing water and putting the plants outdoors 2 or 3 days before transplanting. This will help to prevent transplant shock and premature bolting. Regular watering is essential to prevent leaves from getting bitter. Most varieties will be ready for harvesting as baby leaves in half the days shown on the packet. Harvest Pick individual leaves or wait and harvest full heads. Summer lettuce stays in prime eating condition only a short time, so harvest promptly and keep planting. In fall and winter the plants stay in good eating condition longer.
