Spring: Both warm and cool-season wildflowers can be planted in the spring. At a minimum, the soil temperatures should be 50 degrees.
Early Summer: To ensure proper seedling vigor we recommend seeding wildflowers by June 15th so the wildflowers can establish before winter.
Dormant: Both warm and cool-season wildflowers can be dormant seeded. Soil temperatures need to be at or below 40 degrees.
