How To Grow From Seed

When sowing outdoors, plant at a depth of 1/4 inch in light soil in the early spring, before the last expected frost. If growing indoors, sow in peat pots about 8 weeks before final frost, and transplant outdoors after frost danger. These seeds germinate best in dry and well-drained soils. Make sure to keep moist until germination, which takes around 7-14 days. Sow 1-2 seeds per plant, and then thin emerged seedlings to about 6-10 inches. Plant in full sun, as safflower does best with plenty of light. Note that protection from rabbits may be necessary.

• Soil: well-drained with pH 6.0.-7.0
• Environment: full sun
• Plant spacing: 6-10 inches
