Toatoa prefers consistently moist soil. Water regularly, especially during dry periods, but avoid waterlogging. Allow the top few centimeters of soil to dry out slightly between waterings.

Reduce watering in winter when the plant's growth slows.

Prune to maintain shape and remove any dead or crossing branches. Light pruning can be done anytime to control size or encourage bushier growth.

For significant shaping, prune in late winter or early spring before new growth begins.

Propagation is typically done from seed, which requires stratification to break dormancy. Cuttings can also be taken from semi-hardwood in late summer, though rooting can be slow and may require bottom heat.

Repot toatoa every 2-3 years or when rootbound. Use a well-draining potting mix. Spring is the ideal time for repotting, just as new growth is starting. Handle the root ball gently to minimize transplant shock.
