Water regularly during establishment, especially in dry periods. Once established, Molassesgrass is quite drought-tolerant. Allow the soil to dry out slightly between waterings.

Overwatering can lead to root rot, so ensure good drainage. Reduce watering significantly in cooler months.

Pruning is primarily for aesthetic purposes or to manage size and shape. Cut back flowering stalks after blooming to encourage denser foliage.

If the grass becomes untidy or overgrown, a more significant trim in late winter or early spring will stimulate fresh growth from the base.

Molassesgrass is easily propagated from seed. Sow seeds directly into well-draining soil after the last frost.

It can also be propagated vegetatively by division of established clumps, ideally in spring when new growth begins. Plant divisions at the same depth as the parent plant.

As a fast-growing grass, Molassesgrass may benefit from division and replanting every few years, especially if grown in containers, to prevent it from becoming pot-bound and to revitalize the plant. Repot in spring using a well-draining potting mix, ensuring adequate space for root growth.
