Growing Asparagus in West Jordan
West Jordan sits in Zone 6a, with an average last frost of March 30 and first fall frost around November 1 — giving a 216-day frost-free growing season. Cool-season crops like asparagus benefit from West Jordan's cooler spring and fall windows, when temperatures stay in the 55–75°F sweet spot that produces the best flavor and least bolting.
West Jordan's moderate climate supports asparagus on the standard transplant calendar with minimal special accommodation. Succession planting — sowing fresh seeds or setting new transplants every 2–3 weeks through spring — stretches the harvest window and gives you a backup crop if pests hit the first planting.
West Jordan's caliche soil is rock-hard below the surface — raised beds filled with quality potting mix are the most practical approach for asparagus. Breaking through caliche for in-ground planting requires significant soil amendment, gypsum application, and deep tilling over several seasons. Water at 1 inches per week delivered through drip irrigation for best results in a raised-bed system.

Asparagus Tips for West Jordan Gardeners
- •Plant one-year-old crowns in trenches 6–8 inches deep, spread roots out, and backfill gradually as ferns grow.
- •Never harvest any spears the first year; allow ferns to develop and feed the crown for year-2 production.
- •Succession plant asparagus in West Jordan every 2–3 weeks through spring to extend the harvest window into summer.
Common Asparagus Pests in West Jordan
- •Asparagus Beetle — peaks July in Zone 6a (active May–September); monitor closely during peak season and treat early.
- •Fusarium Wilt — peaks July in Zone 6a (active May–September); soil-borne fungus causing wilting; resistant varieties and crop rotation are key.
