2013 AAS Vegetable Award WinnerrnExcellent taste, a long harvest window and outstanding performance in the trials contributes to this tomatoÃ¢â‚¬â„¢s success. Judges liked the texture and sweetness of the tomato as well as the uniformity of the fruits that grow on vigorous, healthy plants. Jasper is a high yielding variety with fruits that stay on the vine and then hold well after ripening both on the vine and post-harvest. Vigorous vines require little or no fertilization. An added bonus is fusarium resistance and the ability to overcome weather-related stresses.
Start seed indoors 6 – 8 weeks before transplanting out to the garden. Cover seeds with 1/2 cm (1/4 in) of soil. Firm soil over seed. Keep moist but not waterlogged. To germinate maintain a soil temperature of 24 C (75 F). Seed should germinate in 6 – 10 days. Once seeds have sprouted, 14 – 16 hours of light per day is essential. Once plants have reached 12 cm (5 in) transplant to 6 cm (3 in) peat pots. Place the root ball at the bottom of the pot, filling pot with soil will ensure better root development along the stem. Plants will develop better with a growing temperature of 17 C (62 F) until transplanting out. Fertilize weekly with 10-52-17 and liquid seaweed for strong root development. Do not transplant out till night temperatures are warm.
