Asparagus is the garden’s long-term investment. Plant it once and harvest it for 20-30 years. The patience required in years 1-2 pays off in decades of spring harvests.
Zone 2A has a short growing season — start seeds indoors when possible and use season-extending techniques like cold frames and row covers.
Good companions: tomatoes, basil, parsley, asters (repel asparagus beetles)
Avoid planting near: onions, garlic, potatoes
Beginning in year 3; harvest spears when 6-8 inches tall before tips feather out
USDA Hardiness Zone 2A has an average last spring frost around May 30 and first fall frost around Sep 1. All planting dates above are calculated from these frost dates. Your specific location may vary — check with your local extension office for the most accurate dates.
