BLOG Tree Health Myths Debunked: What Every Homeowner Should Know Jul 22, 2025

Trees are an essential part of any landscape, offering shade, beauty, and improved air quality. However, misinformation about tree care can lead homeowners down a path of ineffective or harmful practices. To help you maintain healthy, vibrant trees, we've debunked some common tree health myths that every homeowner should know. Understanding these myths will not only help your trees thrive but also enhance the overall aesthetic and health of your property.

One persistent myth is that trees do not need regular check-ups. Many believe that because trees are hardy, they require little to no attention. While trees are naturally robust, they still face threats from pests, diseases, and environmental changes. Regular inspections by a professional, like those offered by Merriman's Tree Service, can help identify issues early on and provide the necessary interventions to preserve your trees' health.

Another widespread misconception is that all trees require supplemental watering. While young or newly planted trees benefit from regular watering to establish roots, mature trees generally rely on natural rainfall. Overwatering can lead to root rot or disease. It’s crucial to understand the specific watering needs of your trees, which can vary based on species, climate, and soil conditions.

Many homeowners assume that tree topping is a necessary growth management strategy. In reality, topping—cutting back large branches to stubs—can severely damage a tree. Topping stresses trees and leaves them vulnerable to disease and decay. Instead, correct pruning practices should be followed, promoting healthy growth while preserving the natural shape and beauty of the tree.

People often believe that applying wound paint on tree cuts will promote healing. Modern arboriculture suggests otherwise, as wound paint can trap moisture, potentially leading to decay. Trees have evolved an efficient natural process to compartmentalize damage and heal wounds. Allowing this natural process to occur without interference is generally best.

There is a common belief that all insects are harmful to trees. While some insects can cause damage, others play beneficial roles, acting as pollinators or aiding in decomposition. Identifying key species is essential to determining whether intervention is necessary. Seek advice from tree care specialists if you suspect an insect problem; they can provide targeted solutions that protect both your trees and the ecosystem in your garden.

Another myth is that lawns and trees are always compatible. While grass can indeed thrive under some trees, competition for nutrients can lead to stress for both grass and tree. Consider mulching around the base of your trees to reduce competition and provide a clean, nutrient-rich area for your trees to flourish.

Finally, the myth of fertilization must be addressed. It's commonly believed that fertilizing annually is necessary for tree health. However, not all trees require frequent fertilization. Over-fertilization can lead to problems such as excessive foliage growth and vulnerability to disease. Understanding the nutrient needs specific to your trees—and perhaps conducting a soil test—can help determine the best fertilization schedule.

In conclusion, debunking these myths is key to maintaining the health of your trees and, by extension, your property. Insights from experienced professionals like Merriman's Tree Service can guide you in making informed decisions about tree care. Remember, healthy trees contribute significantly to the environment and the value of your home. By avoiding myths and applying evidence-based practices, you can ensure your trees remain strong and beautiful for generations.
