Growing Peas in Logan
Logan sits in Zone 5b, with an average last frost of April 7 and first fall frost around October 22 — giving a 198-day frost-free growing season. Cool-season crops like pea benefit from Logan's cooler spring and fall windows, when temperatures stay in the 55–75°F sweet spot that produces the best flavor and least bolting.
Logan's cooler summers are close to ideal for pea. The same conditions that limit tomato and pepper yields benefit cool-season crops — slower bolting, sweeter flavor, and longer harvest windows. The fall pea crop in Logan is often more productive than the spring crop.
Logan's caliche soil is rock-hard below the surface — raised beds filled with quality potting mix are the most practical approach for pea. 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.

Pea Tips for Logan 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.
- •Fall plantings in Logan often out-produce spring plantings — cooler temperatures slow bolting and concentrate flavor. Light frost can actually improve the taste of pea.
Common Pea Pests in Logan
- •Pea Aphid — peaks July in Zone 5b (active June–August); monitor closely during peak season and treat early.
- •Powdery Mildew — peaks July in Zone 5b (active June–August); white powdery coating on leaves; improve airflow and apply milk spray (1:9 milk-to-water).
- •Root Rot — peaks July in Zone 5b (active June–August); monitor closely during peak season and treat early.
Check plants every 2–3 days during peak season — early intervention prevents most infestations from becoming serious.
What to Plant with Peas in Logan
In Logan's cold 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. In short-season gardens, interplanting companions at transplant time maximizes each bed's productive weeks.
Frequently Asked Questions
When should I plant pea in Logan, UT?
In Logan (Zone 5b), direct sow pea around March 3–13. Soil must be at 40°F or warmer at 2-inch depth before sowing — cold soil rots the seeds.
What zone is Logan, UT for pea growing?
Logan is USDA Zone 5b. For pea, this means a frost-free growing season of roughly 28 weeks running from April 7 to October 22. Cool-season crops like pea thrive in this zone with both spring and fall planting windows available.
When is pea harvest season in Logan?
Expect the first pea harvest in Logan around April 27, with harvest continuing through May 12. This is based on 55–70 days from transplant or direct sow. A fall crop planted August 13–23 adds a second harvest around October 7.
How long does it take to grow pea in Logan, UT?
From transplant or direct sow to first harvest, pea takes 55–70 days in Logan's climate. Based on a typical planting date of March 3–13, expect your first harvest around April 27. Logan's cooler Zone 5b climate often lands at the slower end of this range — cooler nights slow fruit development.
What soil does pea need in Logan?
Logan's caliche subsoil is effectively rock — traditional in-ground planting of pea produces poor results. Build a raised bed with 12–18 inches of quality potting mix or Mel's Mix for reliable production. Break through caliche only for deep-rooted crops, and expect to add compost each year to offset the alkalinity.
