Description
Grow in moderately fertile, medium moisture, well-drained soil in full sun to part shade. Best in full sun. Prefers rich, moist, organic soils. Also prefers moderate summer temperatures over the heat and humidity of the deep South. Needs good air circulation (space well and thin out stems as needed) to help combat potential powdery mildew problems. Intolerant of drought and needs to be watered in dry spells. Avoid overhead watering however. Appreciates a summer mulch which helps keep the root zone cool. For winter, cut plants to the ground and remove from the garden plus clean up all plant areas in order to minimize possible powdery mildew infection for the following growing season.
