When to Plant Lentils in Apache County, AZ

Lentils are an ancient pulse crop producing small, lens-shaped seeds packed with protein and iron. They grow on short, bushy plants and are surprisingly easy to cultivate.

Apache County, Arizona is in USDA Zone 5b. The average last spring frost is May 20 and the first fall frost is October 10, giving you a growing season of approximately 143 days.

At an elevation of 7,720 feet, Apache County receives approximately 9.4 inches of rainfall annually with predominantly sandy loam soil. Summer highs average 92ยฐF, providing good warmth for Lentils during the growing season. Sandy soil warms quickly in spring โ€” great for early planting โ€” but Lentils will need more frequent watering and organic matter to retain nutrients. With low rainfall, drip irrigation is essential for growing Lentils successfully. Mulch heavily to conserve soil moisture.

Lentils Heat Requirements (GDD)

What are Growing Degree Days (GDD)?

Growing Degree Days measure the total warmth your plants receive during the growing season. Think of it as a "heat bank" โ€” every day above 50ยฐF deposits warmth that helps your plants grow.

Each plant needs a certain amount of accumulated heat to mature. If your county provides more GDD than the plant needs, it's a great fit. If it's close, you may want to choose faster-maturing varieties or start seeds indoors to get a head start.

Lentils needs ~1,805 GDD — county provides 2,717 GDD Excellent fit

Growing Tips for Lentils in Apache County

Direct sow Lentils outdoors after May 20 in Apache County when soil has warmed and frost danger has passed.

Sandy soil in Apache County dries quickly โ€” mulch Lentils with 2-3 inches of straw and water deeply 2-3 times per week rather than lightly every day.

Common pests for Lentils in this region include bean beetles and aphids. Use row covers early in the season and inspect plants weekly.

General growing tips

Direct sow in early spring as lentils tolerate frost. Provide short supports as plants tend to lodge. Harvest when lower pods turn brown. Pull entire plants and dry in bundles.
