This all-male variety yields the best-quality spears of the Jersey hybrids. Each mature plant will produce 7-9 quality spears with slightly purple bracts. Spear diameter is between 1-2cm (3/8-3/4"). Jersey Knight has a high tolerance to fusarium wilt and crown rot as well as rust and cercospera. Planting asparagus from seeds is extremely economical, but it's also very slow. We recommend starting seeds indoors and transplanting out into well prepared permanent beds in late spring. To develop strong plants, no asparagus is harvested for the first two years of growth. Rather, the plants are left to develop their tall, ferny foliage. This will allow them to establish thick, functioning roots for nutrient intake. In the third year, 40% of the spears can be harvested.
