Pruning a Giant Dumb Cane (Dieffenbachia) – Safety First

Dieffenbachia sap is highly toxic—wear gloves, wash tools after. To reduce height, cut stems back to a node (small bump) where new branches will emerge. For insurance, propagate via air layering (more reliable) or cane cuttings (easier, take multiple). Dispose of all trimmings where children/pets can't reach.
