Soil must be kept consistently moist, especially the first year. It is not a drought-hardy plant when it is first established. Inconsistent moisture levels during the first year stunts the growth of the plant. However, once the root system has developed, usually in the second year, it does much better under dry conditions. Moist, well-draining loam is the ideal soil type. It does well in heavier soils provided water does not collect and sit.

First-year plants do not bloom, and that is normal. Don’t worry about that. Just focus on keeping them moist and letting the root system develop. Spacing matters more than gardeners expect: 24–36 inches between plants. If you crowd them, you’ll lose air circulation, and that leads to mildew. Eupatorium Maculatum sweet Joe Pye Weed clumps expand over time by rhizomes and self-seed, so divide them every few years to keep them productive.
