How to Grow and Care for Silvergrass (Miscanthus)

These grasses bring beautiful motion and structure to various garden landscapes. Before planting, be aware that their abundant seed heads are especially invasive and can displace native grass species.

Silvergrass is a species of perennial, woody, and clump-forming grass in gardens that is hardy, long-lived, and needs low maintenance. Several species are popular for growing ornamentally in landscapes.

Depending on which cultivar you choose, they can vary greatly in height and spread. They work well behind borders, as a focal point in your landscape, to complement a brightly colored bedding plant.

Water requirements

Miscanthus species are generally very drought-tolerant plants, so you won't need to water them frequently. In fact, overly wet soil is a problem and can cause plants to die in the winter. Generally, species with narrower leaves are slightly more drought-tolerant.

Soil Requirements

The majority of Miscanthus species may thrive in a range of pH level and soil types; all they require is well-drained soil. They are frequently ornamental grass varieties for heavy soils since they survive surprisingly well even though they do best in relatively rich, loamy, and moist soils.

Best Fertilizer of Silvergrass

One major advantage of Silvergrass is that it rarely needs additional compost, especially when mature. The broad rhizomes store enough nutrients to keep them visible during the growing season. In the first few years, while the grass is getting established, a layer of compost made from organic matter is sufficient.

Best Temperature and Humidity

Silvergrass can withstand a wide variety of temperatures, but the plant displays its most impressive flowering in summer. Extremely cold soil temperatures can damage plant rhizomes and are a particular problem when growing.

How to Grow Silvergrass from Seed

Silvergrass can also be grown from seed. Germination is relatively rapid, usually within two weeks. They prefer relatively cool temperatures for germination, no hotter than 75 degrees Fahrenheit.

If you choose to grow them directly in the ground in early spring, only do so in areas where the soil is cool. If sowing indoors, you can plant seedlings when at least two leaves are set.

Care of Silvergrass

Species of silvergrass in garden landscapes have a spreading, rhizomatous root system. It requires enough space and time to develop. For this reason, it is best to plant in early spring (March or April), when the soil is moist and has plenty of time to establish the root system. This helps the grass to better survive drought and frost conditions. With their widespread habit, they do not require staking and grow well in a variety of conditions. A major advantage of silvergrass species is that they are not prone to many diseases and are largely pest free outside their native regions in Asia.
