Water thoroughly when the soil is completely dry. Reduce watering significantly during cooler months, especially in winter, to prevent root rot. Overwatering is the most common cause of demise for this succulent.

Pruning is generally not required for Frailea buenekeri. Remove any dead or dried material as needed to maintain aesthetics and prevent potential fungal issues.

Its compact growth habit means it rarely outgrows its space.

Propagation is best done by offsets (pups) that can be carefully removed from the parent plant once they reach a small size. Allow the offsets to callus over for a few days before planting in well-draining soil.

Repot every 2-3 years or when the plant becomes root-bound. Use a well-draining cactus or succulent mix. Choose a pot that is only slightly larger than the current one, as this species prefers to be somewhat snug.
