Plant Hameln Dwarf Fountain Grass in well-drained soil with full sun exposure. Space plants about 2-3 feet apart. Water regularly during the first growing season to establish a deep root system. Once established, it is drought-tolerant. Fertilize in early spring with a balanced fertilizer. Cut back old foliage to the ground in late winter or early spring before new growth begins. Divide clumps every 3-4 years in spring to maintain vigor.
