Take 3-4 inch cuttings from healthy stems. Place in water or moist soil mix. Roots develop in 1-2 weeks. Maintain high humidity and bright indirect light.

2

Establishment

2-3 weeks

Young plants develop new leaves and establish root systems

Transplant rooted cuttings to containers with well-draining soil. Keep soil consistently moist. Provide bright indirect light. Avoid fertilizer for first month.

3

Vegetative Growth

Ongoing during growing season

Plant produces trailing stems with purple and silver variegated leaves

Pinch back stems regularly to encourage bushier growth. Feed monthly with diluted balanced fertilizer. Maintain humidity levels around 50-60%. Rotate container regularly for even growth.
