Tomato 'Jasper' F1
2013 AAS Vegetable Award Winner

Excellent 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.

How to Grow

Sow in flats, using a soilless peat-based mix 5-6 weeks before plants can be transplanted outside. Keep temperature of the starting mix at 75-90°F. When first true leaves develop, transplant into plug trays or 3-4” pots for large stock 7-8 week transplants. Grow seedlings at 60-70°F. Water only enough to keep the mix from drying. Fertililze with fish emulsion or a soluble, complete fertilizer. Transplant outdoors into medium-rich garden soil 14-20 inches apart. Avoid setting out unprotected plants until night temperatures are over 45°F. Frost will cause severe damage.
