Care
Agastache ‘Prince’s Plume’ Care
Plant in full sun for strongest flowering and fragrance. Well-drained soil is essential, as agastache does not tolerate consistently wet conditions.
Water regularly during the first growing season to establish roots. Once established, plants tolerate moderate drought and prefer soil that dries slightly between waterings.
Fertilization is typically unnecessary in average garden soils. If planting in depleted soil, apply a light application of slow release fertilizer in spring to support balanced growth.
Deadheading spent flower spikes may encourage additional blooming. Cut plants back in late fall or early spring before new growth emerges.
Container Growing: This variety can be grown in large containers with sharply drained potting mix. Container-grown plants require more frequent watering than in-ground plantings. Plants hardy in the ground may require winter protection when grown in containers in colder zones.
