DETAILS

Care Instructions
Agastache rupestris prefers full sun and well-drained soil. It thrives in moderate temperatures and can tolerate dry conditions once established. Regular watering is needed during the growing season, but the soil should be allowed to dry out between waterings. The plant benefits from moderate humidity levels.
Soil
This plant prefers well-drained loamy soil with a slightly acidic to neutral pH. Good drainage is essential to prevent root rot. A sandy or gravelly soil mix can also be beneficial.
Fertilizer
A balanced fertilizer with a nutrient composition of 5-10-5 can be applied during the growing season to promote healthy growth. Fertilize sparingly, as the plant does not require high nutrient levels.
Repotting
Repotting is generally not necessary for Agastache rupestris, but if grown in containers, it can be repotted every 2-3 years. Choose a slightly larger pot with good drainage and fresh soil mix.
Propagation
Agastache rupestris can be propagated by seeds, cuttings, or division. The best time to propagate is in the spring. For cuttings, take a 4-6 inch stem cutting and root it in a well-draining soil mix.
Pruning
Pruning is beneficial for maintaining the plant's shape and encouraging bushier growth. Prune in early spring before new growth begins. Remove any dead or damaged stems and trim back to promote new growth.
Toxicity
Agastache rupestris is not toxic to pets or humans. It is safe to grow in gardens where pets and children are present.
Additional
Agastache rupestris is drought-tolerant once established and can be a great addition to xeriscape gardens. It is also deer-resistant, making it a good choice for areas with wildlife.
