Growing Potatoes 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 potato 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 potato 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 potato. Breaking through caliche for in-ground planting requires significant soil amendment, gypsum application, and deep tilling over several seasons. Water at 1.5 inches per week delivered through drip irrigation for best results in a raised-bed system.
