About Asparagus
Asparagus is a long-term investment — it takes 2-3 years to establish but then produces for 20+ years.
Plant crowns in a permanent bed — asparagus cannot be moved. Do not harvest for 2 years while it establishes. Top-dress with compost each autumn. Allow ferns to grow after harvest to feed the roots.
