Chickpeas 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" — every day above 50°F 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.

Chickpeas needs ~1,021 GDD — county provides 2,945 GDD Excellent fit

Growing Tips for Chickpeas in Marin County

Direct sow Chickpeas outdoors after February 26 in Marin County when soil has warmed and frost danger has passed.

Sandy soil in Marin County dries quickly — mulch Chickpeas with 2-3 inches of straw and water deeply 2-3 times per week rather than lightly every day.

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

General growing tips

Direct sow 4 weeks before last frost as chickpeas prefer cool growing conditions. Avoid overhead watering to prevent fungal diseases. Harvest when pods rattle with dry beans inside.
