This plant prefers moist to well-drained soil. While it can tolerate some dryness, you will want to water it frequently.
No extra fertilizers are needed for this easy-care plant. Drainage should be excellent so that standing water can be avoided. In general, Eroidums like slightly alkaline soil, so position this plant accordingly. Divide it in spring if you like, and if you find your winters are too cold for this plant, dig it up for overwintering in a sunny spot indoors for outdoor replanting in spring.
