Devil's Walkingstick prefers consistently moist soil, especially when young. Water deeply when the top 2-3 cm of soil feels dry. Reduce watering frequency in winter or during periods of dormancy.

Avoid waterlogged conditions, which can lead to root rot.

Prune in late winter or early spring before new growth begins. Remove dead, damaged, or crossing branches. Pruning can also be used to control size and shape, or to encourage a more open growth habit.

Its naturally shrubby form is often desirable.

Propagation is best achieved through root cuttings taken in late winter or early spring. Alternatively, seeds can be collected in autumn and sown in a cold frame, though germination can be slow and erratic.

Division of suckers in spring is also effective.

Aralia spinosa is a vigorous grower and rarely requires repotting unless it becomes root-bound in a container. If repotting is necessary, choose a larger container and fresh, well-draining potting mix.

This is typically done in early spring before active growth commences.
