Water Lysiloma watsonii thoroughly when the top 2-3 cm of soil feels dry. Allow excess water to drain completely to prevent waterlogging. Reduce watering frequency during cooler months or when the plant is dormant.

Overwatering can lead to root rot, so err on the side of slightly dry.

Prune Lysiloma watsonii to maintain its desired shape and size, and to remove any dead, damaged, or crossing branches.

Light pruning can be done anytime, but heavier pruning is best performed in late winter or early spring before new growth begins. Use clean, sharp tools for precise cuts.

Lysiloma watsonii can be propagated from seeds, which require scarification or soaking before sowing.

Cuttings can also be taken from semi-hardwood in summer, treated with rooting hormone, and planted in a well-draining medium. Patience is key as germination and rooting can be slow.

Repot Lysiloma watsonii 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.

Repot in spring before the active growing season begins.
