Fertilize: For sword-leaf dogbane, use balanced fertilizers for optimal growth. Apply a water-soluble fertilizer (10-10-10) every 4-6 weeks during the growing season, and reduce frequency in dormancy. Avoid over-fertilization to prevent damage, and water thoroughly after fertilizing to ensure even nutrient distribution.

Propagation: Sword-leaf dogbane is a hardy perennial viable for propagation by sowing. Prepare a moist, well-draining substrate for optimal seed germination. Sow seeds shallowly, maintain consistent moisture and warmth, thin seedlings after emergence, and transplant carefully to minimize root disturbance.
