Hi Shana,
I hope this will solve your problem:
At planting, place 2 inches of soil over roots and replace more soil as the plant grows. Do not cover tips of spears with soil. Maintain healthy fern growth during the first 2 years to ensure long asparagus production for future years. Asparagus should not be harvested the first year.
Asparagus does not compete well with weeds. Keep weeds and grasses away from plants and mulch with 2 to 3 inches of compost each year. Also, avoid tilling the soil around asparagus, as tilling disturbs the delicate root system.
Formerly it was grown almost entirely with the soil ridged up high over the roots at harvest time so that the shoots would develop in the dark and be white, as harvested. Now, however, we have learned to prefer green shoots which develop in the light, so that ridging is no longer so common.
White asparagus spears are considered a delicacy. To blanch spears, mound soil 8" high over asparagus in early spring before spears emerge. When the tips of the spears emerge through the top of the 8" mound, push a long-handled knife into the base of the hill and spears well below the surface. Pull cut shoots out by the tips and level the mounds after the harvest season.
Happy Gardening!
