While sycamore trees look glorious in your garden, they can be bothersome. They’re deciduous and shed a lot of leaves. Sometimes they can be part of your property but it doesn’t fit the aesthetic.
Therefore, you might be wondering- how to kill a sycamore tree?
You’ll need 3 steps to kill a sycamore tree. You need to girdle or frill to expose the cambium. Then apply a chemical agent that will kill the sycamore from the inside. Lastly, you need to remove the tree and get rid of the stump.
While these methods are simple, there are some extra details you need to pay attention to. For that, we’d love you to spare a few minutes to read our article. We’ve described all the issues below for you.
So what are we waiting for? Let’s begin!
How To Kill A Sycamore Tree In 3 Easy Steps
Now, let’s see how you can kill a sycamore tree in 3 steps. You need one external method to expose the transport vessels and one internal method to administer a chemical. The last step is to remove the stump.
Although the process is quite lengthy, you’ll need a few tools for this. These include:
- Bleach or herbicide
- Epsom salt, compost, or fertilizer
Once you have all these at hand, it’s time to kill that sycamore!
Step 1: External Processes- Girdling Or Frilling to Expose The Cambium
To effectively kill a sycamore, you need to make sure it dies all the way through. So you have to start outside and work your way inwards.
This is where girdling and frilling come in. Each of these methods exposes the cambium of the tree. That’s the transport network of the tree that moves water and nutrients.
Now, girdling requires time and a bit of experience. If you have both, go for it. If you’re a beginner, opt for frilling.
Girdling The Bark
Girdling is the process of cutting grooves and removing some of the bark.
To girdle, you’ll need a knife or icepick and a chainsaw. First, use the knife to score and mark out the grooves on the tree trunk. Make sure these grooves are about 2 inches deep into the trunk.
Once you’ve marked the circumference of the trunk, get to work with the chainsaw.
Cut 1 inch deep notches into the trunk between the grooves with the chainsaw. As you work your way around, the bark should loosen so that you can easily remove it.
Frilling The Trunk
If you think girdling is too much effort, you can pick frilling. This will expose the cambium just as well.
The first step to frilling is similar to girdling. You need to make 2 inch deep grooves into the tree trunk. Make sure to cover the entire circumference of the trunk.
In the places you’ve marked the grooves, use the chainsaw to drill through the trunk. Make sure these downward cuts are 2 to 3 inches deep into the trunk.
As you cut, the bark will fall, exposing the cambium.
Now that we’ve succeeded in the first step, let’s move on!
Step 2: Internal Processes- Using Bleach Or Herbicide
Now you have access to the tree’s transport system.
So prepare your chemicals. You’ll need a bleach solution or water-soluble herbicide. Unsure about which one to use?
Have a look at the options we think are best suited for the task!
Now, fill up a sprayer bottle with your chosen chemical agent. Then spray directly onto the exposed cambium until it looks completely wet.
Once sprayed, the chemical agent will travel all around the plant. This will slowly kill the sycamore tree inside out.
For best results, spray the sycamore tree 3 times a week for 1 month. Depending on the tree’s height, this is more than enough time for the method to work.
You’ll know the tree is dead when the cambium looks brown and dry.
Step 3: Remove The Tree And Stump
Now all that’s left is to remove the tree. You can hire a professional if the tree is taller than 15 meters. If it’s shorter, simply use a chainsaw to cut through.
Once that’s done, you can remove the stump easily in 2 ways.
If the tree stump is smaller than 20 inches in diameter, simply dig it up. Use a shovel and dig out all the major connecting roots. Sometimes, it may even be necessary to cut the roots.
The second method is for wider stumps. Use a drill to drill holes into the stump, about 2 inches deep. After that, cover the entire stump with Epsom salt, compost, or fertilizer and leave it for 1 week.
This will rot the stump and make it soft to handle. After a week, it should be pliable and easy for you to dig out of the soil. Once removed, you’re done with the task.
With all of that covered, you know all there is about managing a sycamore tree. If all else fails, call a professional.
