Should You Worry About Lichen on Trees?

Lichens are fascinating and often misunderstood. When homeowners notice these growths on the bark of trees, it raises concerns about the health of their yard. If you notice lichens on your trees, consult a professional for pertinent information guaranteed to put your mind at ease. As a professional tree care company, the Driscoll Tree Service can help you understand what lichens are, their causes, whether they threaten trees, and if any action is needed.

What Are Lichens?

Lichens are a complex symbiotic relationship between a fungus and an alga. This partnership creates a unique organism that can thrive in various environments, including tree bark. Lichens are diverse, coming in different shapes, colors, and sizes. Although they are not plants, they are a combination of two distinct organisms working together. The fungus provides structure and protection, while the alga conducts photosynthesis, producing food for both.

Causes of Lichen Growth on Trees

Lichens grow on trees primarily because of favorable environmental conditions. Like most fungi, they are commonly found in areas with clean air, adequate sunlight, and sufficient moisture. Tree bark provides an excellent environment for lichens to attach to and thrive on. Despite this relationship, lichens do not harm trees, so you don't have to worry about health concerns or tree removal emergencies. Instead, they show a healthy environment, as they are susceptible to air pollution and will not grow in contaminated areas.

Are Lichens Harmful to Trees?

The most common question homeowners as tree service providers is whether lichens are harmful. As mentioned, lichens do not harm the trees they grow on. They do not penetrate the bark or draw nutrients from the tree. They use the tree's surface to live without risking diseases, decay, or structural damage. Therefore, their presence should be something other than a cause for alarm and frequent maintenance calls to a local tree care company.

Should You Remove Lichens?

Now that you know about lichens, it is unnecessary to remove them. Attempting to remove lichens can increase susceptibility to diseases and pests. In addition, using chemicals to remove lichens can harm the tree and the surrounding environment. Certified arborists often recommend leaving lichens alone and appreciating their presence as a sign of a healthy ecosystem.

When to Be Concerned

While lichens are not harmful, their sudden increase may sometimes show underlying issues. If a tree is already stressed because of poor health, it might become more susceptible to lichen growth, prompting a tree service call. You should monitor the overall health of your trees, looking for signs such as dead branches, leaf discoloration, or reduced growth. If any of these symptoms are present, it is advisable to consult a professional to assess the tree's condition and recommend lasting solutions like tree removal in case of severe deterioration.

Lichens on trees are a natural and often beneficial part of the environment. They are not harmful to trees, and their presence shows good air quality and a healthy ecosystem. It is advisable to focus on maintaining the overall health of your trees and enjoy the unique beauty that lichens bring to your landscape. If there are health concerns, contact the experts at the Driscoll Tree Service. Our certified can assess all the crucial aspects and tailor a solution that protects the tree without risking your landscape's wellbeing.
