If you notice a gray, green, or sometimes yellow mossy substance growing on your trees, it’s probably lichen. Lichen is a fascinating organism that often raises questions among homeowners and gardeners about its effects on trees. If you are wondering whether lichen is harmful to trees in your yard, consult a trusted tree care company like Sesmas Tree Service for pertinent information and comprehensive services. Our seasoned arborists can inspect, diagnose, and address minor issues before things become worse. Let’s look at vital aspects of lichen to help you make informed decisions.
Lichen is a symbiotic organism that’s composed of fungi and algae. These fungi live together in a mutually beneficial relationship, whereby fungi provide a protective structure for the algae, which produces food through photosynthesis. Lichen can grow on various surfaces, including rocks, soil, and tree bark. It is often mistaken for moss because of its similar appearance, but lichen is a unique organism with distinct characteristics.
Lichen usually grows in areas with clean air and sufficient sunlight. This means your trees get good air quality, as lichen is sensitive to pollution and does not thrive in contaminated environments. If you live in a humid and shaded area, the chances of lichen growth are high. The growth pattern and coloration can vary, so look out for crusty, leafy, or shrubby appearance on the bark. Any other type of growth on your trees should be inspected by a professional tree service provider to mitigate infections and infestations.
The most common concerns about lichen is whether it harms the trees it grows on. The good news is that lichen is not parasitic and does not feed on the tree. It uses the tree bark as a substrate to anchor itself, so you don’t have to worry about damage or premature tree removal emergencies. Since Lichen does not penetrate the tree’s tissues or draw nutrients from it, it is harmless to healthy trees. However, weak or infected trees may experience direct damage from lichen growth, prompting professional intervention by a trusted tree care company.
While lichen itself is not harmful, it can sometimes show underlying issues with the tree. Excess lichen growth may show decline, as lichen thrives on slower-growing or weakened trees with more stable surfaces. If you notice an unusual amount of lichen, call a professional tree service provider to inspect the tree for signs of stress or disease. In addition, dense lichen growth can sometimes cover the tree’s bark, making it harder to detect issues such as fungal infections or insect infestations.
Lichen offers several ecological benefits. It plays a crucial role in the ecosystem by providing food and habitat for various small organisms, including insects and birds. Lichen also contributes to soil formation by breaking down rocks into smaller particles. In addition, lichen is used in traditional medicine and scientific research because of its unique properties and ability to produce various bioactive compounds.
You don’t require arborists to manage or remove lichen. However, if you prefer to reduce its presence for aesthetic reasons or to monitor the tree’s health more easily, there are gentle methods to do so. Pruning overhanging branches to increase sunlight and airflow can reduce lichen growth. Also, gently scrubbing the lichen with a soft brush and water can help remove it without damaging the tree bark.
Lichen on trees is usually not a cause for concern. This symbiotic organism does not harm the tree and can even show good air quality in your environment. While its presence can sometimes show underlying health issues, it is harmless and offers various ecological benefits.
