Read the label carefully for instructions about how to mix the concentrate for the best results. It should be applied using a pump or tank sprayer, and it stays where spray. One application is typically enough, and you should see results in two to three weeks.
Types of Brush Killers
There are basically two types of brush killer: concentrate and ready-to-use.
Concentrated brush killers have to be mixed with water before application. There’s usually a detailed guide for how to mix concentrate on the product label. Generally, you should use a stronger concentration for plants that are particularly hard to kill.
The exception to this is if you’re using the product to kill a tree stump. In this case, most products should be applied right from the bottle, without diluting it with water. Stumps are very difficult to kill, which is why you have to use most of these products at full strength.
Ready-to-use brush killers come premixed in a large container that includes a wand for easy application. These are generally not as effective on stumps because they’re not as concentrated, but you may still have some success if you follow the instructions carefully.
When is the Best Time to Spray Brush Killer?
Timing is important. Not only do you have to choose the right brush killer, but you also have to apply it at the right time for maximum effect. The simple answer is to apply a brush killer when the weeds are actively growing, but there are a few other things to consider.
Because of how most of these formulas work, brush killers should be applied to mature leaves during periods of active growth. Brush killer enters the plant through the leaves and travels to the roots, and this process happens much faster when the plant is actively growing.
Another thing to consider is the weather. Read the package instructions carefully to determine how long it takes the product you’re using to be water-resistant. For some, this is in as little as two hours. For others, it might be days.
This is important to keep in mind because if the product you’re using needs more time to be absorbed into the leave, a rain shower will wash the effective ingredients away before the product gets a chance to really start working.
You also have to consider the wind. Applying these harsh chemicals on a windy day is not recommended because it gets very hard to apply the product precisely. Some of it will inevitably blow away, landing on healthy plants and potentially causing extensive damage.
Read the instructions carefully to see if the product mentions anything about ideal temperatures or what time of day it should be applied. Sometimes, temperatures that are too hot aren’t ideal because the plants aren’t growing as quickly, meaning the brush killer will be less effective.
Applying these and other weed killers in the early morning is usually a good idea. Avoid the middle of the day and early afternoon when the sun is highest and the day is usually hitting its peak temperature.
How to Use Brush Killer?
The first thing you should do is cover any plants or flowers you want to keep safe, especially on windy days. These products are pretty powerful and can kill anything they come in contact with, so if you have plants that mean a lot to you, the best thing to do is cover them.
Wear long sleeves and pants, gardening gloves, and safety glasses to protect yourself as you work.
If you’re using a concentrate, follow the instructions on the package for how to mix it. Usually, you will need a pump or tank sprayer, but if you have a smaller area to cover, a spray bottle can sometimes work best.
If you’re using a ready-to-spray brush killer, you don’t have to worry about mixing anything. Just read the instructions to learn how to use the attached spray handle.
Some people like to use a surfactant when applying a brush killer. This is an additional ingredient that you either spray on the leaves before applying the chemical brush killer or that you mix in with it.
Surfactant helps the liquid brush killer stick better to the leaves, making sure that as much as possible gets absorbed. There are plenty of commercial surfactants available if you plan to go this route.
Now, you’re ready to start applying. Squeeze the trigger and apply the liquid directly to the leaves of the plants you’re trying to kill. Saturate them, but avoid dripping if possible.
If you’re trying to eliminate vines or tree stumps, follow the manufacturer directions. Most of them suggest applying the concentrate itself directly to a freshly cut stump. Others may give you an option for basal bark application when you apply the spray to the bottom few inches of the tree trunk without cutting it down first.
After application, you wait. These products can take anywhere from one to 10 weeks for the full effects to be seen. Clean up any dead vegetation using gloves, and apply a second coat if you’re not getting the results you want.
FAQs
1. Difference Between Weed Killer and Brush Killer
The biggest difference between weed and brush killer is that brush killer is much stronger. While weed killers can handle some invasive plants pretty easily, brush killers are more effective on those that are extremely difficult to get rid of.
One of the reasons for this is that the woody stems and vines are just a little harder to kill. That’s why when you’re trying to kill a tree stump, you have to use most products at full strength.
2. How Long Does It Take for Brush Killer to Work?
It depends on the product, the plant, and the application. If you use a stronger recommended concentration and apply it in the right way at the right time of day, you may see results in as little as 24 hours.
Early results like yellowing leaves are encouraging because they show that the plant is reacting to the brush killer. That said, it still takes time for the chemicals to work their way through the plant and into the roots.
Most of these products will give you full results in about eight to 10 weeks.
3. Does Brush Killer Kill Grass or Trees?
Unless the product specifically says it’s safe for trees and grass, you should assume that it’s harmful and take the proper precaution.
Wrap the bottom of your trees to prevent the brush killer from coming in contact with the bark. Although this might not kill the tree right away, it can damage it which may lead to a lot of problems down the line.
If you’re applying these products to plants around your lawn, be very careful when applying. Avoid drips. You only want to get the brush killer on the leaves of what you’re trying to kill.
You should also check the label to see how long you have to wait before replanting. Some of these products get into the soil and cause some damage, so you have to wait until some time has passed before you can plant anything.
