Dill 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.

Dill needs ~838 GDD — county provides 2,512 GDD Excellent fit

Growing Tips for Dill in Santa Fe County

Direct sow Dill outdoors after May 10 in Santa Fe County when soil has warmed and frost danger has passed.

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

Common pests for Dill in this region include carrot rust fly and parsleyworm. Use row covers early in the season and inspect plants weekly.

General growing tips

Direct sow in spring as dill has a taproot and dislikes transplanting. Succession sow for continuous leaf harvest. Allow some plants to flower for seeds and to attract beneficial insects.
