Care Notes

Water regularly during the first growing season to establish the plant. Once established, Switchgrass is drought-tolerant, but appreciates occasional watering during prolonged dry spells. Generally, Panicum virgatum 'Prairie Sky' does not require much feeding. A light application of a balanced granular fertiliser in spring can promote vigorous growth, but avoid over-fertilising. Cut back old foliage in late winter or early spring, just before new growth appears. Trim it down to about 10-15 cm (4-6 inches) from the ground. This helps maintain a tidy appearance and encourages fresh new growth. Switchgrass is generally trouble-free, rarely affected by serious pests or diseases. Leave the dried foliage and seed heads on the plant throughout winter. This provides valuable architectural interest and food for birds, and also offers some protection to the crown of the plant.
