- **Timing:** Plant coneflowers in the spring or early fall to allow them time to establish before the extremes of summer or winter.
- **Spacing:** Space plants about 1 to 3 feet apart, depending on the variety. Check the plant tag for specific spacing recommendations.
- **Planting Depth:** Dig a hole as deep and twice as wide as the root ball. Gently remove the plant from its container, loosen the roots, and place it in the hole so the top of the root ball is level with the soil surface. Backfill the hole, gently tamp down the soil, and water thoroughly.
