Water Rhabdophyllum arnoldianum thoroughly when the top 2-3 cm of soil feels dry. Avoid overwatering, as this can lead to root rot.

Reduce watering frequency during the cooler, dormant months to prevent waterlogged conditions. Ensure good drainage to allow excess water to escape.

Prune Rhabdophyllum arnoldianum to maintain its desired shape and size, and to remove any dead or damaged stems.

Light pruning can be done at any time of year, but heavier pruning is best done in late winter or early spring before new growth begins. Use clean, sharp tools.

Propagate Rhabdophyllum arnoldianum from stem cuttings. Take cuttings of about 10-15 cm length in spring or summer. Dip the cut end in rooting hormone and plant in a well-draining potting mix.

Keep the soil consistently moist and provide bottom heat for best results.

Repot Rhabdophyllum arnoldianum 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.

Repotting is best done in spring, just as new growth begins, to minimize transplant shock.
