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.
Gardening in Arizona
Arizona spans dramatic climate zones from cool mountain forests to hot desert. Low-elevation cities like Phoenix grow year-round; high-elevation areas are Zone 5-6.
