Water:
Dumbcane thrives in high humidity and requires balanced watering weekly to maintain health. Sensitive to cold, it is usually cultivated indoors or in well-drained containers, emphasizing its need for controlled moisture.
Fertilize:
Fertilize dumbcane every six weeks with a balanced, water-soluble fertilizer during spring and summer, reducing to every eight weeks in fall and winter. Water before fertilizing and flush soil occasionally to prevent salt buildup for optimal plant health.
Pruning:
Prune dumbcane in early to late spring by trimming leggy stems and damaged leaves to encourage bushier growth. Sterilize tools to prevent disease and wear gloves due to irritating sap. Regular pruning enhances air circulation and light, rejuvenating older plants and controlling size.
Propagation:
Dumbcane is valued for its large, mottled leaves. For propagation, take stem cuttings (4-6 inches) including leaf nodes and place them in water or moist soil. Maintain high humidity and warmth; rooting hormone is optional. Once rooted, plant dumbcane in well-draining potting mix.
