Sowing Tips
Soil Temperature
Direct sow or transplant when soil at planting depth holds 55°F for reliable germination and early growth.
Expert Note
For the best blooms, sow directly after your last spring frost when soil is warm, and thin to the spacing listed on your seed packet to prevent tall, floppy plants.
