Key traits and growing stats from plant data
Watering, pruning, propagation, and repotting details from plant data
During active growth and flowering, keep the soil consistently moist but not waterlogged. Allow the top few centimeters of soil to dry out slightly between waterings.
Reduce watering significantly as the plant enters dormancy, allowing the soil to dry completely. Overwatering can lead to tuber rot.
Remove spent flowers (spathes) by cutting the stem near the base to encourage more blooms and maintain a tidy appearance. Yellowing or damaged leaves can also be removed as needed.
After flowering, allow the foliage to die back naturally as the plant enters dormancy, which helps the tuber store energy for the next season.
Zantedeschia rehmannii is primarily propagated by dividing the rhizomes or tubers during its dormant period, typically in late winter or early spring before new growth begins.
Carefully separate offsets, ensuring each piece has at least one "eye" or growth point. Plant them in well-draining soil at the appropriate depth.
Repotting is generally done every 1-2 years, or when the plant becomes root-bound, during its dormant phase. Choose a pot only slightly larger than the previous one, ensuring it has good drainage.
Refresh the soil with a fresh, well-draining potting mix. Handle tubers gently to avoid damage.
