Water regularly during the first year to establish a deep root system. Once established, Echinacea tennesseensis is drought-tolerant. Water when the top 2-3 cm of soil feels dry, especially during prolonged dry spells.

Avoid overwatering, as it can lead to root rot.

Deadhead spent flowers to encourage reblooming and maintain a tidy appearance. Cut back dead foliage in late winter or early spring before new growth emerges.

Avoid cutting back too early in fall as the seed heads provide winter interest and food for birds.

Echinacea tennesseensis can be propagated by seed or division. Sow seeds in fall or early spring, or stratify them in the refrigerator for 4-6 weeks.

Divide established clumps in early spring or fall every 3-4 years to rejuvenate the plant and prevent overcrowding.

Repotting is generally not necessary for established garden plants as they have deep taproots. If growing in containers, repot every 2-3 years in spring to refresh the soil and provide more space for root growth.

Use a well-draining potting mix.
