Lichen on Trees: Here Are 4 Ways to Get Rid of It

How to Get Rid of Lichen on Trees


If you have noticed that lichen has settled on the tops of your trees, then this is the ideal blog for you. They may not be harmful to the tree, but it is true that they look bad. That is why today we bring you this guide so you can learn how to get rid of lichen on trees. We are going to show you four ways you perform this task easily and quickly.

Mosses and lichens simply live on trees for support. They do not penetrate under the bark nor take advantage of the tree’s resources. Algae, lichens, and moss can often form a green or medium gray type of growth, which is dusty or mossy. This can be of great concern to gardeners.

Although they are harmless at times, this may indicate that there is a lack of vigor in the affected plant.

These organisms are more visible after wet weather since mosses and lichens are present throughout the year. However, they are usually more visible in the winter time. The problem is that they are often mistaken for a serious fungal disease, although fortunately, they do not harm the plants in which they grow.

4 Ways You Can Get Rid of Lichen on Trees Quickly 

Lichen is a fungus and a photosynthetic plant. It usually grows in humid conditions.

The problem with this fungus is that it can grow out of control and overindulge. That is why it is good to know tricks on how to eliminate it when it starts to become unpleasant. We know that some people don’t have time to take care of their trees and that is why we reduced this guide to four basic ways.

Here we bring you four ways you can remove lichen on trees:

  1. Manual extraction is the oldest method
  2. The copper sulfate will help you remove it quickly
  3. Spray potassium on your trees to eliminate lichen
  4. Baking soda is considered the safest solution

It is important to note that, while lichen will not technically harm a tree, it can make its appearance worse. Each of these four methods are safe and will help you get rid of lichen quickly. We invite you to follow our blog so you can learn how to get rid of this and other types of problems such as caterpillar webs in trees.

Manual Extraction Is the Oldest Method 

Remove Lichen Manually

If you are deciding to remove this problem from the bark of your tree, then this is the first method you should consider. This is the simplest and most effective way to get rid of lichen. To do this, make a wooden scraper or find a plastic one, make sure it is not too hard.

The lichen layer is removed to healthy wood so that not the slightest trace of unnecessary vegetation remains. It is best to do this in the spring since it separates more easily and possible damage to the trunk will heal faster.

The Copper Sulfate Will Help You Remove It Quickly 

Use Copper Sulfate to Remove Lichen

This is one of the most recommended methods of lichen removal. Copper is a common ingredient in most dry fertilizers and is an antifungal treatment. Copper is the slowest solution, but it is the most effective. As a systemic spray, it is considered effective in attacking and killing lichen.

However, copper-based sprays can damage tree growth. Trees are recommended to be sprayed before sprouting begins or later in the season. In other words, you must be careful when using this solution. Check the label to make sure it can be safely applied to lichen on trees.

Spray Potassium on Your Trees to Eliminate Lichen 

Spray Potassium to Remove Lichen

Using potassium to spray trees with lichen is another method that quickly kills this problem. Potassium is considered a contact killer. So, for example, if your tree is sprayed in the morning, the moss should be dead by that afternoon, or within a couple of days for sure.

While potassium kills lichen, it will not harm your tree. In fact, it is a root fertilizer that is beneficial to the tree. That is why we recommend this option. We are sure that it will give you quick solutions without damaging your trees.

Baking Soda Is Considered the Safest Solution 

Use Baking Soda to Eliminate Lichen on Trees

Baking soda is considered the safest solution, aside from manual extraction, to kill lichen. But once again, there are things to keep in mind when choosing this method. Baking soda is high in salt, so it should not be used on trees with new growth, as this can cause damage.

Like potassium spray, baking soda is also a contact killer and very effective. Before use, it is recommended that you manually remove as much of the lichen as possible and then spray the affected trees.

We hope this guide has helped you understand how to remove lichen on trees. Now you know that the fastest and most effective options are potassium and bicarbonate spray. You can also opt for the manual solution since it is the simplest and does not carry risks. We are here to guide you, feel free to contact us if you have any questions.
