asparagus takes two years from planting for you to harvest. The first year you let the plants go to seed (they get tall, spindly and look like a fern on top). You need to mulch them this fall. The second year you will need also to let them go to seed and mulch in the fall. By the third year they will be ready to harvest. Asparagus plants should be allowed to become well established before any spears are harvested. You can fertilize in the early spring. I hope this helps.
