Growing Peas in Pueblo
Pueblo sits in Zone 6b, with an average last frost of March 22 and first fall frost around November 10 — giving a 233-day frost-free growing season. Cool-season crops like pea benefit from Pueblo's cooler spring and fall windows, when temperatures stay in the 55–75°F sweet spot that produces the best flavor and least bolting.
Pueblo's moderate climate supports pea 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.
Pueblo's well-draining loam soils are among the best for pea growing — focus on annual organic matter additions (2 to 3 inches of compost) and consistent moisture during drier months. Water pea at 1 inches per week; loam holds moisture evenly without the drought-crack cycle of heavy clay or the rapid-drain losses of pure sand.

Pea Tips for Pueblo Gardeners
- •Soak pea seeds overnight before planting to speed germination in cool soil.
- •Install a 4–6 foot trellis at planting time — peas climb from day one and produce more per square foot when supported.
- •Succession plant pea in Pueblo every 2–3 weeks through spring to extend the harvest window into summer.
Common Pea Pests in Pueblo
- •Pea Aphid — peaks July in Zone 6b (active May–September); monitor closely during peak season and treat early.
- •Powdery Mildew — peaks July in Zone 6b (active May–September); white powdery coating on leaves; improve airflow and apply milk spray (1:9 milk-to-water).

What to Plant with Peas in Pueblo
In Pueblo's moderate climate, Carrot and Radish are the most beneficial plants to grow alongside pea. Carrot shares root-zone space without competing because carrot roots run deeper than most companions. Keep pea away from Onion — it inhibits bean and pea growth through sulfur-compound allelopathy.
