Ornamental grasses, while beautiful and low-maintenance, do require some care to keep them looking their best. One important aspect of maintaining ornamental grasses is cutting them back on a yearly basis. This is typically done in late winter or early spring.
The main reason for cutting back ornamental grasses is to remove the old growth and make way for new growth in the coming season. By cutting back the grasses, you allow them to rejuvenate and produce fresh, healthy foliage. This also helps to maintain the overall shape and appearance of the grasses.
When it comes to the timing of the cut back, late winter or early spring is generally recommended. This is because the grasses are dormant during this time, and cutting them back at this stage won’t harm them. Additionally, cutting back in late winter allows for the new growth to emerge in spring, providing a fresh and vibrant look to your garden.
To cut back ornamental grasses, you can use pruning shears or hedge trimmers. Start by gathering the foliage into a bundle or tuft, and then cut it back to a few inches above the ground. It’s important to wear gloves and protective clothing to avoid any potential cuts from the sharp blades.
After cutting back the grasses, you can choose to leave the clippings on the ground as mulch, or you can compost them. The clippings can provide some insulation for the soil, help retain moisture, and eventually break down to nourish the plants.
In addition to cutting back ornamental grasses annually, it is also recommended to divide them every four or five years. Dividing helps to maintain the health and vigor of the grasses, as well as prevent overcrowding. Over time, ornamental grasses can become dense and compact, leading to poor growth and reduced visual appeal. Dividing them allows for the formation of new plants and ensures that each individual grass has adequate space to thrive.
To divide ornamental grasses, you can use a sharp spade or garden fork to carefully dig up the clump. Once lifted, you can separate the clump into smaller sections, making sure each division has a good portion of roots and shoots. Replant the divisions in desired locations, ensuring they have enough space to grow and spread.
It’s worth noting that some gardeners choose to leave their native grasses in place during winter for their aesthetic appeal and to provide food and shelter for birds. If you decide to leave the grasses uncut over winter, it’s important to cut them back before new growth emerges in spring.
Ornamental grasses do benefit from being cut back every year. It helps rejuvenate the plants, maintain their shape, and promote healthy growth. Dividing them every four or five years also ensures their long-term health and prevents overcrowding. By following these simple maintenance practices, you can enjoy the beauty of ornamental grasses in your garden year after year.
