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 4,902 GDD Excellent fit

Growing Tips for Lentils in Jackson County

Direct sow Lentils outdoors after March 06 in Jackson County when soil has warmed and frost danger has passed.

Sandy soil in Jackson 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.
