We suggest Tennis Ball or Buttercrunch Lettuce as replacements
Very popular in England and Australia. As the name implies it can be sown at any time – spring to fall and will be slow to bolt. The crisp, tight hearts are an appealing light green with the centers appearing a bit blanched.
Germination: 4-10 days
Germination Temperature: Optimum soil temperatures 60-75 degrees F. Soil above 75 degrees F inhibits germination.
Seed Sowing Depth: ¼ inch deep
Outside Sowing: Spring when the soil temperature reaches at least 50 degrees F. Sow 1” apart, thin to 6-12”, depending on the size of lettuce you want, baby to full heads. Keep soil moist during germination. Sow every 2-3 weeks for a longer harvest period. Sow heavy seeded rows every 10-14 days for baby greens using the 1 oz. Pinetree Lettuce Mix.
Starting Indoors: 3-4 weeks before planting outside. Sow 2-3 seeds per cell/pot, thinning to one per cell/pot. Provide 60-70 degrees F soil temperatures. Transplant out, 8-12” apart in rows 12” apart.
How much does a packet plant: 25-foot single row
Harvest: Cut whole heads at the base or snipe off individual leaves.
Tips: Lettuce needs fertile soil for optimum growth. Work in compost or well-rotted manure into your soil before planting. Provide adequate, even moisture for the best growth. Mulching helps retain moisture.
