How to Cut Weeds with a Weed Whacker

This is a guide for cutting weeds with a string trimmer or weed whacker. As usual, follow all safety precautions before starting. This video shows you some of the ways to achieve this.

Before You Start

Decide what type of string trimmer to use. Electric trimmers work for most, but your movement is limited by the cord. Cordless models are not as powerful but give you freedom of movement. Gas units offer the most power but are heavy.

Whether you use a gas or electric weed whacker, take all necessary precautions. These trimmers are sharp and can cause injury if you are not careful. Wear goggles, gloves, steel toe boots and a long sleeve shirt.

Clear the area of debris. Remove as many rocks, plastic, pieces of wood, mulch and other objects from the ground. This makes the area safer to work in for the operator. It also reduces the chance of the trimmer catching something (a rock for example) and getting clogged.

Step 1

Pull out 6-8 inches of line from the trimmer. Some like to remove the trimmer guard so they can get more line, but 6 inches is enough to remove weeds.

If you have an electric trimmer, press the on button. If you are using a gas-powered unit, crank the engine. You might have to pull the cord several times and prime the fuel first. Refer to your owner’s manual.

Use one hand to hold the handle and your other hand on the trigger. Ensure the trigger is always level to your waist. This posture is considered the safest and most comfortable for most.

Step 3

Start cutting weeds. Take care not to trim plants close to the area. Be as thorough as possible. If you are trimming a large area, divide it into sections.

Cutting weeds can take a lot of time. If it is hot and you have a lot of work to do, take frequent breaks. Have a bottle of water ready and look for some shade if it gets too hot.

Set the trimmer about an inch above the weeds. Move the trimmer in a side to side manner. Try to be as steady as possible. if you have a Proyama Wd Wacker, this is how you start cut weeds.

If you are having trouble getting to the weeds, try to use the nylon tip of the line. This is the most efficient method and should be able to remove the weeds.

Do not attempt to cut all the weeds in one pass. This can overload the electric motor or gas engine. Cut a few and then do another pass. Even then it might require multiple passes if the weeds are large, thick and clustered together.

Step 4

One of the potential problems you can run into is if the trimmer cuts the grass too low. Any weeds hiding there would be exposed to more light and grow faster.

The way to avoid this is to get rid of all the weeds in that area. If you have to cut the grass down, make sure to eliminate any weeds there. Depending on the situation, you might have to pull some out with your hands too. If you do pull them out, do so at the roots.

When you are done, apply a chemical solution to the area to prevent the weeds from sprouting. There are a lot of these available online.

Some people like to use a lawn mower to clean up after the trimmer. That depends on how much weed growth is in the garden. Use a lawn mower if you feel that the trimmer was not able to remove as much of the weeds as you would like.

Clean the trimmer after use. Clear the area as well.

How long this takes depends on the size of your yard and how widespread the weeds are. That is why it is important to trim them as soon as possible.
