Arisaema dracontium prefers consistently moist soil. Water thoroughly when the top inch of soil feels dry. Avoid waterlogged conditions, which can lead to root rot.

Reduce watering significantly during its dormant period in late fall and winter, allowing the soil to dry out between waterings.

Pruning for Arisaema dracontium is generally minimal. Remove any dead or yellowing foliage in late fall after the plant has died back, or in early spring before new growth appears.

This helps maintain a tidy appearance and prevents disease.

Propagation is typically done through seed or division. Seeds require stratification and can be slow to germinate. Division is best performed in early spring as the plant emerges from dormancy.

Carefully separate offsets from the main corm, ensuring each piece has at least one eye.

Repot Arisaema dracontium every 2-3 years or when the corm has outgrown its container. This is best done in early spring before active growth begins.

Use a well-draining potting mix, such as a blend of peat, perlite, and compost. Ensure the new pot is only slightly larger than the previous one.
