2013 AAS Vegetable Award WinnerrnExcellent taste, a long harvest window and outstanding performance in the trials contributes to this tomato’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.
