Lucky Bean Plant (Castanospermum) Dropping Green Leaves

A Lucky Bean plant (Castanospermum australe) dropped green leaves after thriving all summer in a north-facing frosted window. The owner never pruned it.

Causes of Green Leaf Drop

• Seasonal light reduction (especially in frosted north window)
• Cool temperatures (<60°F)
• Under- or overwatering (usually causes yellowing first)
• Lack of pruning (can lead to legginess and leaf shed)

Pruning Guidance

Prune any stem back to just above a node (leaf attachment point). Use sharp scissors. New growth emerges below the cut. Best done with a photo for specific advice; the expert offers a pruning article via email.
