White Snakeroot Growing and Maintenance Tips

Often late to emerge in the spring, they grow best in an average, medium to wet, well-drained soil, in full sun to partial shade. Very adaptable to most conditions and become drought tolerant once established. In full sun and extended dry periods leaves may scorch. Pinch back stems in June to encourage a more compact, bushy plant. If planted in deep shade, eupatorium will become leggy and require staking. The overall height and width of eupatorium can vary depending on its growing conditions. Spent flowers can be left for winter interest and food for birds.
