Ensure good drainage to prevent issues.

Deadhead spent flowers to prevent seed formation if desired, though it's not strictly necessary. Remove any dead or damaged foliage in late fall or early spring before new growth begins.
Trillium generally requires minimal pruning.
Propagate by division of established clumps in late summer or early fall. Seeds can be sown fresh, but germination is slow and may take several years. Division is the most reliable method for home gardeners.
Repot only when necessary, typically every 3-5 years, or when the plant becomes pot-bound. This is best done in late summer or early fall after the foliage has died back. Use a well-draining potting mix.
