We’ll share all the details you need to know about algae control for trees in this post.
Why Does Algae Grow on Trees?
Algae love moist environments. You’ll find them on your tree if the tree is in a shady area where air circulation is also generally poor. Similarly, overwatering your tree can also lead to algae growth. So, seeing algae on trees is almost always a sign of moisture problems.
Should You Be Concerned About Tree Algae Growth?
Generally, you shouldn’t really worry about algae on trees. Unlike other invasive species, algae will not compete with your trees for nutrients or hamper the tree’s growth. So, when most people are worried about algae on trees, it’s often from an aesthetic standpoint.
However, you should be worried if the algae growth is excessive for a few reasons.
Firstly, the appearance of excess algae on trees is far from pleasant to look at. If you’ve invested money into your landscape to get it looking great, the last thing you need is algae ruining the aesthetic appeal.
Secondly, excessive algae growth combined with other signs of stress, such as dead branches or disease, could be a sign that the tree is struggling with moisture-related issues or other possible nutrient deficiencies.
Additionally, a thick layer of algae growth can block sunlight from reaching a significant portion of the tree’s bark. This is not good for photosynthesis, especially in young trees without much canopy spread.
So, if you feel the algae on trees around your landscape is unsightly and excessive, you should be worried. Inspect the tree more closely for signs of stress and disease and call an arborist if necessary.
Managing Algae on Trees: How to Remove It
If you’re thinking about algae removal from trees, you have a few options:
- Let in more sunlight. Consider pruning or removing landscape features blocking sunlight from reaching the tree. A few days of consistent sunlight is usually enough to dry out the bark and eliminate algae thriving on the moisture.
- Wash off the algae. Depending on the thickness of the algae growth, a light spray of water from a hose can dislodge the algae. Avoid using high-pressure water spray because you might end up damaging the bark of your tree.
Preventing algae growth on trees is as simple as taking steps to ensure adequate sunlight and proper air circulation around the tree.
