Water: Mountain tansy mustard thrives in arid conditions, showing high drought tolerance. Watering should occur weekly to avoid soil oversaturation. Suitable for xeriscaping, mountain tansy mustard withstands low rainfall and requires careful watering during its growing season to support development and flowering.

Fertilize: Mountain tansy mustard requires periodic fertilization for optimal growth. Apply balanced fertilizers in spring and switch to high-nitrogen before flowering. Fertilize quarterly as per label instructions; avoid over-fertilization. Halt feeding in winter, and dilute fertilizers to half-strength to prevent root burn.

Pruning: Mountain tansy mustard is a perennial herb with small yellow flowers. Prune dead stems and thin crowded growth in early to late spring for optimal health. Regular maintenance encourages blooms and prevents disease, resulting in a more vigorous and visually appealing plant.

Propagation: Mountain tansy mustard propagates well from seeds sown on a well-draining soil mix. For germination, surface sowing is key, as seeds need light. Maintain consistent moisture without waterlogging, thin seedlings post-germination, and handle gently during transplantation. Regular watering and pest monitoring are crucial for growth.
