Allow the soil to dry out completely between waterings. Beaucarnea purpusii stores water in its bulbous trunk, making it highly drought-tolerant. Overwatering is the most common cause of root rot.

Water thoroughly when the top 5-10 cm of soil feels dry, and ensure good drainage.

Pruning is rarely necessary for Beaucarnea purpusii. If required, it's usually to remove dead or damaged leaves. Use clean, sharp shears and make cuts close to the trunk.

Avoid heavy pruning, as this can detract from its natural sculptural form. Focus on maintaining a healthy, balanced appearance.

Propagation is best achieved through seeds, which can be slow to germinate. Sow seeds in a well-draining seed-starting mix and keep them consistently moist and warm.

Alternatively, offsets may occasionally form at the base of mature plants and can be carefully separated and potted.

Repot Beaucarnea purpusii every 2-3 years or when it becomes root-bound. Use a fast-draining cactus or succulent potting mix.

Choose a pot that is only slightly larger than the current one, as these plants prefer to be somewhat snug. Repot in spring before active growth begins.
