When to Seed St. Johns Wort

St. John’s Wort should be direct seeded outdoors in fall, or stratified indoors and sown in trays for transplanting after all danger of frost has passed. 

Where to Plant St. Johns Wort

This plant will appreciate a spot with full sun to partial shade. Loose, well-draining soil is ideal but this plant will tolerate an extremely wide range of growing conditions. This perennial bloom will come back year after year. It will readily spread and reseed, so keep this in mind when choosing a location! Plants reach two to three feet tall. 

Growing St. Johns Wort

Sow seeds on the surface of the soil and three to four inches apart. It needs light to germinate, so take care not to cover the seeds. Once germinated, thin your seedlings to 12 to 18 inches. When established, this herb is low maintenance.

Harvesting St. Johns Wort

St. John’s Wort can be harvested for cut flowers, teas or salves, or left to mature in the garden to benefit the many pollinators and bird species that are attracted to it.
