Care
Mountain Mint Care
Plant in full sun for strongest growth and flowering. Light shade is tolerated but may reduce bloom production.
Grow in average, well-drained soil. Mountain Mint adapts to clay, sandy soils, and lean sites once established, but avoid areas that remain waterlogged.
Water regularly during the first growing season to establish roots. Established plants are drought tolerant and generally require minimal supplemental watering.
Fertilizer is optional. If desired, apply a light application of slow release fertilizer in spring.
Cut stems back in late fall or early spring. Plants may be divided every few years to manage spread and rejuvenate growth.
