Allow the soil to dry out completely between waterings. Overwatering is a common cause of root rot in Zamia species. Water thoroughly when the top several centimeters of soil are dry, ensuring good drainage.

Reduce watering significantly during cooler, dormant periods.

Pruning is generally minimal for Zamia onan-reyesii. Remove only dead, damaged, or diseased fronds by cutting them at the base of the plant.

This helps maintain the plant's aesthetic and prevents potential disease spread. Avoid cutting healthy fronds.

Propagation is primarily through offsets (pups) that form at the base of the mature plant. Carefully separate these offsets during repotting, ensuring they have some roots attached.

Allow the cut surface to dry for a day or two before planting in well-draining soil.

Repot only when the plant becomes root-bound, typically every 2-3 years. Use a well-draining potting mix, such as a cactus or succulent blend with added perlite.

Choose a pot that is only slightly larger than the current one. Repot in spring before active growth begins.
