St John's Wort prefers well-drained soils in full or partial sun. You may have some unwanted seedlings sprout up from seeds or roots. Those can be pulled or roots cut if needed. It isn’t aggressive if other competition is present. Due to its height, it is best planted at the back of gardens to avoid crowding and shading.
For planting in pots, winter sow seeds for two months before spring. Simply sprinkle seeds on top of soil.
Easily grown in moist, well-drained soils in full sun to part shade.
