Salvia 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.

Salvia needs ~1,580 GDD — county provides 5,056 GDD Excellent fit

Growing Tips for Salvia in Ellis County

Direct sow Salvia outdoors after March 09 in Ellis County when soil has warmed and frost danger has passed.

With Ellis County's clay soil (37% clay), work in 3-4 inches of compost before planting Salvia. Avoid tilling when soil is wet to prevent compaction.

General growing tips

Start indoors 8-10 weeks before last frost; seeds need 65-70°F soil and light to germinate (surface-sow, do not cover). Transplant after last frost when soil has warmed.
