Trattinnickia aspera prefers consistently moist soil but dislikes waterlogged conditions. Water thoroughly when the top 2-3 cm of soil feels dry.

Reduce watering slightly during cooler months or periods of slower growth to prevent root rot. Ensure good drainage to avoid issues.

Prune Trattinnickia aspera to maintain 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.

Propagation of Trattinnickia aspera is typically done through seeds or stem cuttings. Seeds should be sown in a well-draining seed-starting mix and kept moist and warm.

Stem cuttings can be taken in spring or summer, dipped in rooting hormone, and planted in a similar medium.

Repot Trattinnickia aspera every 2-3 years or when it becomes root-bound, preferably in spring. Choose a pot that is only slightly larger than the current one.

Use a well-draining potting mix, such as a blend of peat moss, perlite, and compost.
