Care
Agastache ‘Prince’s Plume’ Care
Plant in full sun for best flowering, fragrance, and overall plant performance. Well-drained soil is essential, as agastache does not tolerate consistently wet conditions.
Water regularly during the first growing season to establish a strong root system. Once established, plants tolerate moderate drought, though occasional watering during prolonged heat or dry periods will help support continued flowering.
Fertilization is typically unnecessary in average garden soils. If planting in poor or depleted soil, a light application of slow release fertilizer at planting can support healthy early growth without encouraging excessive foliage.
Deadheading spent flower spikes can encourage continued blooming. Cut plants back in late fall or early spring to refresh growth for the following season.
