Coix Gasteenii prefers consistently moist soil, especially during its active growth period. Water thoroughly when the top 2-3 cm of soil begins to feel dry. Avoid waterlogged conditions, which can lead to root rot.

Reduce watering slightly during cooler months or dormancy.

Pruning for Coix Gasteenii is generally minimal. Remove any dead, damaged, or yellowing leaves as they appear to maintain a tidy appearance and promote plant health.

Occasional thinning can be done to improve air circulation if the plant becomes too dense.

Coix Gasteenii can be propagated by seed or by division. Seeds should be sown in spring, either directly outdoors or started indoors a few weeks prior.

Division is best performed in early spring before new growth begins, separating the rhizomatous root clumps.

Repot Coix Gasteenii every 2-3 years, or when it becomes root-bound. Choose a pot that is slightly larger than the current one. Use a well-draining potting mix.

Repotting is best done in early spring before the active growing season commences.
