Allow the soil to dry out completely between waterings, especially during the dormant period. Water thoroughly when the top few centimeters of soil are dry.

Reduce watering significantly when the plant enters dormancy, typically after the inflorescence or leaf has died back. Ensure good drainage to prevent root rot.

Pruning is generally not required for Amorphophallus zenkeri. Remove any dead or dying leaves or flower stalks by cutting them at the base once they have completely withered.

This helps maintain a tidy appearance and prevents potential fungal issues. Avoid cutting healthy foliage.

Propagation is primarily done through offsets or corms. Carefully separate offsets from the mother corm during repotting. Plant the offset in well-draining potting mix. Alternatively, mature corms can be divided.

Ensure each piece has an 'eye' for successful germination and growth.

Repot the corm every 2-3 years, or when it outgrows its current container, typically in spring before new growth emerges. Use a well-draining, porous potting mix. Choose a pot slightly larger than the corm.

Ensure the top of the corm is just below or at the soil surface.
