Allow the soil to dry out completely between waterings during the active growing season. Reduce watering significantly when the plant goes dormant, providing only enough to prevent the corm from desiccating.

Overwatering is a common cause of rot.

Pruning is generally not required for Amorphophallus konjac. Remove any dead or yellowing leaves as they appear to maintain tidiness. The flower stalk also dies back naturally after blooming.

Amorphophallus konjac is typically propagated by separating offsets (cormels) from the main corm during repotting. Ensure each offset has at least one viable bud. Plant them in well-draining soil and keep them warm.

Repot every 2-3 years or when the corm has outgrown its container. This is best done when the plant is dormant. Use a well-draining potting mix and a pot that allows ample room for the corm to expand.
