Set out plants 15 to 18 inches apart, bearing in mind that each plant will spread up to 36 inches in two years. Don’t worry about soil, sun or moisture; Aegopodium will grow almost anywhere, making it the perfect choice for difficult patches where other plants have failed.
In northern areas, we recommend a winter mulch for the first few years, until plants are fully established. Otherwise, no special care is needed.
