Seeds were sown at a depth of approximately 1/4 inch. Flats were hand watered. There was 37% germination. | ||

Seeds were started in a greenhouse in April. Greenhouse temperatures did not exceed 90F (high) and 50F (low). Maximum germination was reached within 3 weeks. At 6 weeks, seedlings were pricked out and transplanted directly into 4x10 Anderson plant bands and moved outdoors into a shade house with 63% shade cover. Containers were hand watered. | ||
