Top-end bamboo requires consistent moisture, especially during establishment and dry periods. Water deeply and regularly, allowing the top few centimeters of soil to dry out slightly between waterings.

Avoid waterlogged conditions, which can lead to root rot. Reduce watering slightly in cooler months if growth slows.

Prune Top-end bamboo to manage its size and shape, and to remove any dead or damaged culms. This can be done at any time of year, but late winter or early spring is ideal before new growth emerges.

Cut culms at the base to maintain a tidy appearance and encourage air circulation.

Propagate Bambusa arnhemica through division of established clumps. In spring, carefully dig up a section of the rhizome with several culms attached.

Replant the division in well-draining soil, ensuring it is watered regularly until established. It can also be grown from seed, but this is less common.

Repotting is generally only necessary for container-grown plants when they become root-bound, typically every 2-3 years. Choose a pot that is significantly larger than the current one.

Ensure the new pot has adequate drainage holes. Repot in spring, using a well-draining potting mix.
