Water thoroughly when the top 2-3 cm of soil feels dry to the touch. Avoid overwatering, as Glandora gastonii prefers slightly drier conditions and is susceptible to root rot.

Reduce watering frequency during the dormant winter months to prevent waterlogged soil.

Prune Glandora gastonii in late winter or early spring before new growth begins. Remove any dead, damaged, or crossing branches to maintain a tidy shape and encourage robust flowering.

Light pruning can also be done after flowering to shape the plant.

Propagation is typically done through stem cuttings taken in late spring or early summer. Dip the cut end in rooting hormone and plant in a well-draining potting mix.

Keep the cuttings moist and in a warm, bright location until roots develop.

Repot Glandora gastonii every 2-3 years or when it becomes root-bound. Choose a pot that is only slightly larger than the current one.

Use a well-draining potting mix, such as a cactus or succulent blend, to ensure good aeration and prevent waterlogging.
