· Hi Troy,
Asparagus grown from seed should not be harvested until the third year. Asparagus planted from 1-year crowns can be harvested lightly on the next year after planting. Keep the harvest to a limited amount. Harvest asparagus in the second year after planting crowns, but do not harvest for more than one month the first time. When the diameter of the spears is less than the size of a pencil, cease harvesting. The plant is still expanding its feeder roots and storage root system, and excessive removal of spears weakens the plant. Starting in the forth year the spears may be harvested from April in to June. Harvest spears that are 5 to 8 inches in length by cutting or snapping. To cut a spear, run a knife under the ground where the spear is emerging. Since the spear will be cut below the point of fiber development, snapping the stem is necessary. Cutting may damage some spear tips that have not yet emerged from the ground. To snap a spear, bend it from the top toward the ground. The spear breaks at the point where it is free of fiber.
I would leave the smaller spears alone allowing the plant to gain strength. The smaller spears could be a result of harvesting too soon or too heavy. Maybe next year you will notice improvement.
How old are the plants?
