Care and Maintenance of Fountain Grass

Watering and fertilizing

A. Watering and Fertilizing: Fountain grass is drought tolerant once established and should only need to be watered during extended periods of drought. When watering, the soil should be damp but not soggy. It is best to water deeply, rather than frequently, to encourage deep root growth. Fertilize fountain grass in early spring with a balanced fertilizer for optimum growth .

Pruning and trimming

Fountain grass should be pruned in late winter or early spring before new growth begins. To maintain its attractive appearance, trim off any dead or discolored foliage as well as any old panicles that have gone to seed. Prune back the plant by up to one-third; this will encourage new growth and help keep it compact and manageable.

Disease and pest control

Fountain grass is generally hardy and resistant to most diseases and pests, but it is important to check the plant regularly for signs of stress or damage. Repeatedly wet foliage can cause the plant to develop fungal diseases such as rust, powdery mildew, or leaf spot. These can be treated with a fungicide if necessary. To deter pests, use gentle insecticidal soap or neem oil.

Not only does it provide visual interest, but it also helps to control erosion and attract beneficial wildlife. With its hardy nature and drought-tolerance, fountain grass is a great choice for gardeners of all levels. When cared for properly, it can thrive in a variety of climates and provide years of enjoyment.
