Axonopus brasiliensis prefers consistent moisture. Water deeply when the top 2-3 cm of soil feels dry. Avoid waterlogged conditions, which can lead to root rot. In hotter, drier periods, increase watering frequency.

Ensure good drainage to prevent issues.

Pruning is generally not required for Axonopus brasiliensis unless it is being used as a groundcover or for specific landscaping purposes. If trimming is needed to maintain shape or density, use sharp shears and prune lightly during the active growing season.

Axonopus brasiliensis is primarily propagated through division of established clumps. This is best done in spring. Carefully separate the rhizomes and plant them into well-draining soil.

Alternatively, seeds can be sown in spring in a warm environment, but germination can be slow and inconsistent.

Repotting is rarely necessary for Axonopus brasiliensis as it is a spreading grass often used outdoors. If grown in a container, repot only when it becomes root-bound, typically every 2-3 years, using a slightly larger pot with fresh, well-draining potting mix.
