Landscapers Warn Against Harmful 'Mulch Volcano' Trend Threatening Trees

What's Happening?

A landscaping trend known as 'mulch volcanoes' is causing concern among tree care professionals. This practice involves piling excessive amounts of mulch around the base of trees, which can trap moisture and lead to rot, disease, and other issues. The roots may encircle the trunk, eventually strangling and killing the tree. The trend has been criticized for its aesthetic and environmental impact, with experts advising against it. Instead, they recommend a donut-shaped mulch application that keeps the tree's root flare exposed. The practice has been observed in various regions, including Ontario, Canada, and has been linked to the decline of tree health in residential and commercial landscapes.

Why It's Important?

The 'mulch volcano' trend poses a significant threat to urban and suburban tree health, which can have broader ecological and economic impacts. Trees play a crucial role in urban environments by providing shade, improving air quality, and supporting biodiversity. The decline of tree health due to improper landscaping practices can lead to increased maintenance costs, reduced property values, and loss of ecosystem services. Raising awareness about proper mulching techniques is essential to preserving tree health and ensuring sustainable landscaping practices. This issue highlights the need for education and regulation in the landscaping industry to prevent harmful practices.

Beyond the Headlines

The trend of 'mulch volcanoes' reflects a broader issue of misinformation and lack of awareness in landscaping practices. It underscores the importance of educating homeowners, landscapers, and property managers about sustainable and environmentally friendly landscaping techniques. This situation also presents an opportunity for the landscaping industry to promote best practices and develop guidelines to prevent similar issues in the future. Additionally, it highlights the role of community organizations and local governments in advocating for tree health and urban forestry initiatives.
