Caring for Shenandoah switch grass is relatively easy once it is established. However, during its first growing season, it benefits from regular watering to help it establish a strong root system. In this answer, I will provide you with detailed information on how to care for Shenandoah grass, including watering, pruning, fertilizing, and dealing with pests and diseases.
Watering: During the first growing season, it is important to provide Shenandoah switch grass with approximately one inch of water per week. This can be achieved through rainfall or supplemental irrigation. It is important to water deeply and infrequently to encourage the roots to grow deep into the soil. Once established, Shenandoah grass is drought-tolerant and does not require as much watering.
Pruning: Shenandoah switch grass does not require much pruning, but you can trim it back in early spring before new growth emerges. This will help maintain a neat and tidy appearance. Simply cut back the grass to a height of 6-8 inches using sharp pruning shears. Avoid cutting it too short as this can damage the plant.
Fertilizing: Shenandoah grass is relatively low-maintenance and does not require heavy fertilization. However, you can apply a slow-release fertilizer in early spring to provide some nutrients. Choose a balanced fertilizer with equal or similar amounts of nitrogen, phosphorus, and potassium. Follow the instructions on the fertilizer packaging for the correct application rate.
Pests and diseases: Shenandoah switch grass is generally resistant to pests and diseases. However, it may occasionally be susceptible to foliar diseases such as leaf spot or rust. To prevent these issues, avoid overhead watering and ensure good air circulation around the plant. If you notice any signs of disease, such as brown or discolored spots on the leaves, you can treat it with a fungicide labeled for use on ornamental grasses.
Personal experience: I have grown Shenandoah switch grass in my own garden and have found it to be a resilient and low-maintenance plant. During its first growing season, I made sure to provide it with regular watering to help it establish strong roots. Once established, it required very little care and continued to thrive even during periods of drought. Pruning was minimal, and I only needed to trim it back once a year to maintain its shape. I did not encounter any major pest or disease issues, but I kept an eye out for any signs of trouble and treated them promptly if necessary.
Caring for Shenandoah switch grass involves providing regular watering during its first growing season, pruning it back in early spring, applying a slow-release fertilizer, and being mindful of pests and diseases. With proper care, Shenandoah grass can be a beautiful and low-maintenance addition to your garden or landscape.
