Water: Rayed tansy prefers conditions similar to its native habitat with periodic dry spells. It is drought-tolerant, needing water every 2-3 weeks once established. Thriving outdoors, it benefits from natural rainfall, making it ideal for temperate climates with minimal human watering.

Fertilize: For optimal health, rayed tansy requires balanced nutrition fertilizers, applied bi-weekly during growth and monthly in dormancy. Limit to a tablespoon per plant to prevent nutrient burn, and always water afterward. Adjust feeding as rayed tansy matures. Use gloves for safety during fertilization.

Pruning: Rayed tansy requires early spring pruning to enhance growth and air circulation. Remove dead stems and spent blooms to improve appearance and prevent self-seeding. Pruning maintains shape, reduces pests, and encourages vibrant foliage, ideally timed with new growth for optimal development and flowering consistency.

Propagation: Rayed tansy propagates effectively through cuttings. Cut a healthy, non-flowering shoot with leaves and plant it in well-draining soil. Maintain consistent moisture and provide indirect sunlight to promote root growth. After rooting, gradually acclimatize to outdoor conditions before transplanting to its final location.
