Plant Montrose White Calamint in well-drained soil with full sun exposure. Space plants about 12-18 inches apart. Water regularly during the first growing season to establish a deep, extensive root system. Once established, it is drought-tolerant. Prune in early spring to encourage bushy growth and remove any dead or damaged stems. Fertilize lightly in spring with a balanced fertilizer. Divide clumps every few years to maintain vigor.
