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 Alaska
Alaska ranges from subarctic to maritime climates. The interior has very short summers but intense sunlight. Coastal areas are milder. Cold-hardy crops and greenhouses are key.
