Water
Indiangrass prefers moderate moisture. Water regularly during the establishment phase.
Once established, it is quite drought-tolerant and benefits from deep watering only during prolonged dry periods to encourage robust root development.

Watering, pruning, propagation, and repotting details from plant data
Indiangrass prefers moderate moisture. Water regularly during the establishment phase.
Once established, it is quite drought-tolerant and benefits from deep watering only during prolonged dry periods to encourage robust root development.
Prune Indiangrass in late winter or early spring before new growth emerges. Cut back the old, dead foliage to about 10-15 cm from the ground.
This tidies the plant and stimulates healthy new growth, while also providing habitat for overwintering insects.
Indiangrass is primarily propagated by seed or division. Seeds can be sown in early spring, either directly outdoors or started indoors.
Division of established clumps is best done in early spring or fall, separating healthy portions with roots and shoots.
Repotting is generally not necessary for Indiangrass as it is a perennial grass. If propagation is done by division, the divided sections are essentially being 're-potted' into their new locations, establishing new root systems.
