Keep the soil consistently moist during the growing season, especially when the plant is actively producing leaves and flowers. Reduce watering significantly during its dormant period, allowing the soil to dry out between waterings to prevent root rot.

Remove any yellowed or dead leaves as they appear to maintain the plant's appearance and health. Cut back the foliage to the ground level once it naturally dies back after the flowering season, typically in late summer or early autumn.

The Apulian arum can be propagated by dividing its tubers during the dormant season, usually in late autumn or early spring. Replant the divisions in well-draining soil, ensuring they are planted at a suitable depth.

Repot the Apulian arum every 2-3 years, preferably in early spring before new growth begins. Choose a pot that is slightly larger than the current one and use a well-draining potting mix to accommodate its tuberous root system.
