Shipping Information & Notes

Growing Information


CULTURE: Sow seeds in desired medium 6-8 weeks prior to transplanting. Maintain a constant 80-90°F (27-32°C) soil temperature. When first true leaves just show, transplant the seedlings into cell-type containers or blocks. 2" or larger containers will produce larger, stronger root systems; 4" blocks are the standard. Grow plants at a constant 66-68°F (19-20°C) day and night temperature. After cotyledon leaves have expanded, fertilize with a complete nutrient solution (EC 1.0, pH 5.8) or equivalent as needed to keep plants dark green and healthy; increase EC as plants grow. When transplanting into the greenhouse, maintain 73-77°F (23-25°C) day and night temperature for a few days after transplanting to promote rapid vegetative growth and root establishment. Once fruit begins to set, lower night temperature to 62-66°F (17-19°C) and keep a daytime temperature of 68-72°F (20-22°C).
TRELLISING: It is recommended to prune the plants to 1-2 stems and trellis up a string.
HARVEST: Fully vine-ripen fruit only for local retailing or use. Pick fruit less ripe the further the distance and the longer the time between harvest and the customer.
DISEASES AND PESTS: Use crop rotation or new media to reduce soil-borne disease problems. Regularly schedule releases of beneficial insects to control pests.
DAYS TO MATURITY: From transplanting.
Transplants: Avg. 950 plants/1,000 seeds.
SEED SPECS: Seeds/oz.: (varies): 6,875-15,625 (avg. 8,750).
PACKET: 15 seeds, unless otherwise noted.
