Landscaping Essentials: The Indispensable Role of Decorative Grasses

In the ever-evolving world of landscaping, ornamental grasses are making a significant impact, gaining popularity around the country. These perennial grasses offer a unique blend of beauty and resilience, making them an attractive choice for garden enthusiasts.

As individual grass plants grow larger, their centers may die, necessitating division of the clumps. However, with proper care, these plants can thrive for many years. One key aspect of maintaining ornamental grasses is timing. Cutting back these plants in late winter ensures healthy new growth come the new year.

When it comes to choosing the right ornamental grass for your garden, it's essential to consider the local environment. To avoid invasive species that could potentially harm your garden and the surrounding ecosystem, opt for native, non-invasive grasses adapted to local conditions. Examples of such grasses include native sedges (Carex species) and grasses with low spreading tendencies. It's also crucial to avoid planting known invasive species like Japanese knotweed or Canadian goldenrod. Regular monitoring and maintenance can prevent the garden escape of potentially invasive plants.

The variety of native grasses available is astounding, with a diverse range of sizes, shapes, and colours. These grasses not only enhance the aesthetic appeal of your garden but also contribute to its charm during all four seasons. In a snowy winter garden, for instance, the frozen flowering heads of ornamental grasses provide a striking contrast.

Native perennial grasses require less irrigation, fertilizer, and pesticides than regular grass, making them an eco-friendly choice. It's important to note that some ornamental grasses are invasive and should be avoided, as they can quickly take over your landscape as well as neighbouring land. To ensure you're making the right choice, it's advisable to check with your state's invasive plant listing before selecting grasses.

When planting ornamental grasses, the crown of the grass should sit just above the soil surface. For groundcover or large area plantings, using plugs or bare root plants is a cost-effective option.

Ornamental grasses add a wealth of unique patterns, colours, and textures to your yard. Grass shades range from traditional green to blue, red, and purple. Some ornamental grasses grow most actively in warm weather, while others thrive during cooler weather. These have come to be known as warm season grasses and cool season grasses. Warm season grasses turn brown and stop growing in the winter but are only dormant and will turn green in spring or early summer when the weather warms.

When it comes to planting, warm season grasses should be planted in spring, while cool season grasses can be planted either in spring or autumn. Maintaining good air circulation around the plants helps prevent rust diseases.

Container plants are more suitable for installing a few specimen grasses. Over the longer term, dead stems should be cut back in late winter or early spring if they become a fire hazard. During the first year, ornamental grasses need regular watering, especially in sandy soil.

Tall vertical decorative grasses, like giant reed grasses, can even work as hedges, while others are mounding and low to the ground. With their versatility and charm, ornamental grasses are an excellent addition to any garden.
