Does Groundcover Need Mulch?
Groundcover is a great way to add beauty and functionality to your landscape. It can help prevent soil erosion, retain moisture, and reduce the need for weeding. But when it comes to mulching, many people are unsure whether or not it is necessary for groundcover. In this article, we will explore the benefits of mulching groundcover and answer the question: does groundcover need mulch?
The Benefits of Mulching Groundcover
Mulching has many benefits for groundcover. First and foremost, it helps to retain moisture in the soil. This is especially important during hot summer months when water evaporates quickly from the soil surface. Mulching also helps prevent soil erosion by holding the soil in place and reducing the impact of heavy rainfall.
In addition to these benefits, mulching groundcover can also help to suppress weed growth. When weeds do start to grow, they are often easier to pull out because their roots are not as firmly anchored in the soil. Finally, mulching can also help to regulate soil temperature, keeping it cooler in the summer and warmer in the winter.
Choosing the Right Mulch for Groundcover
Not all mulches are created equal, and it is important to choose the right one for your groundcover. Organic mulches, such as bark chips or shredded leaves, are a good choice because they break down over time and add nutrients to the soil. Inorganic mulches, such as gravel or stones, are also an option, but they do not provide any nutritional benefit to the soil.
When choosing a mulch, it is also important to consider the type of groundcover you are using. Some groundcovers, such as creeping phlox or thyme, prefer a more acidic soil, while others, such as sedum or stonecrop, prefer a more alkaline soil. Choosing a mulch that is appropriate for your specific groundcover can help ensure its success.
How to Mulch Groundcover
Mulching groundcover is a fairly simple process. Begin by removing any weeds or debris from the area, then spread a layer of mulch over the soil surface. The thickness of the mulch layer will depend on the type of mulch you are using, but generally, a layer of two to three inches is sufficient.
It is important not to pile mulch up against the stems or trunks of plants, as this can cause them to rot. Instead, leave a small gap between the mulch and the plant, called a "mulch donut."
The Bottom Line: Does Groundcover Need Mulch?
The answer to this question is yes, groundcover does need mulch. Mulching provides numerous benefits to groundcover, including retaining moisture, preventing erosion, suppressing weeds, and regulating soil temperature. When choosing a mulch, it is important to select one that is appropriate for your specific groundcover, and to apply it correctly for maximum benefit.
