How to Deal With Black Olive Tree Stains

Keeping greenery in your yard, local park, or anywhere else it might be found can be a tough job for anyone to undertake. This is especially true if a person doesn’t know the reason why something doesn’t look green or if they don’t know of a solution to some of the aesthetic issues found with trees. Black olive tree stains are among the most common eye sores for people who like to keep their trees looking perfect. Unfortunately, solutions are hard to come by because the issue is not widely discussed outside of botanical circles.

If you are experiencing Florida black olive tree stains and want to make them go away, then the team at Zimmerman Tree Service is here to help. Below we shed some light on where these stains come from and how you can make them go away. This black olive tree nuisance has been around for as long as the trees themselves, but that does not mean there is no solution to revitalize the appearance of your trees!

Where Stains on Black Olive Trees in Florida Come From

Many know the black olive tree nuisance, and the stains that come from them, are often small black dots. We have all seen them. But where do they come from? The answer is not from the tree leaking sap or from the leaves secreting anything, as is commonly believed. The source is one of the creatures that call the tree home – caterpillars.

Caterpillars inhabit trees and leave black olive tree stains because of leaving droppings from the food they are eating. This part of the caterpillar’s activities often leads to the unfavorable stains you see on your property.

As a tree cleaning service that has operated in South Florida for years, our team understands just how tough these stains can be to remove from a tree. They can be even harder to get rid of once some time has passed since the caterpillar left them there. Our team also understands that trying to remove these stains yourself can be very tricky.

Luckily, there are solutions to the problem if you are willing to consider them. These solutions may prove to be a bit more intense or even completely different from whatever course of action you previously believed needed to be taken. However, we want to share the best way to ensure that your trees remain in amazing condition and aesthetically pleasing. 

Cleaning Your Black Olive Trees Properly

Black olive tree stain removal and prevention is not as simple as simply washing a tree with water or scrubbing it down aggressively. In fact, scrubbing can actually damage a tree’s aesthetic or overall health even further. Instead, black olive tree stains should be cleaned with a specific method that is guaranteed to at least lessen the appearance of the spots on your tree.

Our tree-cleaning experts recommend the following process: 

  • Fill a bucket with warm water and soak a rag or other material in it for roughly 5 minutes.
  • Mix 3 tablespoons of vinegar and salt together.
  • Put a spoonful of the vinegar and salt mixture on the stain and let it sit for about 5 minutes. 
  • Rinse the stain with water and scrub lightly with the rag until the stain is gone. 
  • Feel free to use a light soap as part of the cleaning process if the results are not to your liking.

This should prove enough to remove the stains. Know that it can be time-consuming if the entire tree, parts of the sidewalk surrounding it, or anything else in the proximity of the origin of the stains is also affected. For this reason, you should always use an experienced team that provides tree cleaning services to ensure that the tree remains looking amazing while also getting to the origin of the problem.
