In the second year, the whole process above can be repeated. Ideally, you don’t harvest any of the fresh young stems in this second season. Allow them to fully develop once more. By doing this, you will assist the plants in developing strong roots before you tax them and harvest the young shoots.
In all following years, your asparagus can be harvested for about 6 weeks. During your harvest, you can expect about 15 to 20 asparagus shoots per plant. After the 6 week harvest period, any new shoots should be allowed to mature as before, to continue nourishing the crowns below the ground. Keep your beds weed free at all times and feed heavily with compost every autumn.
