Retail products are available that are designed to kill brush and weeds, but the price tag on these products can often be quite high. Instead, consider making your own homemade brush killer. These homemade solutions are made of inexpensive ingredients that are most likely already in the home, and they work just as effectively as high-priced retail products.
A simple homemade vinegar solution works effectively to kill brush, weeds, and poison ivy. Pour one-half gallon of apple cider vinegar into a spray bottle, and spray the vinegar all over the brush, especially targeting the roots of the brush. This solution can be used on gardens and other parts of the lawn, as the vinegar will not prevent vegetation from growing. This is not a permanent fix, so the solution will need to be reapplied as brush grows back. Repeat this process once a day for an entire week, and the brush will die off on its own.
Vinegar and Salt
A solution of vinegar and salt works effectively for brush and weeds along driveways, roads, and sidewalks. This solution should not be used in gardens or where you plan to grow grass, as heavy amounts of salt in the soil will prevent vegetation from growing for several years. In a spray bottle, mix a solution of one gallon apple cider vinegar, and two cups of table salt. Spray this mixture over the brush every day for one week, spraying as close to the roots as possible. The brush will quickly die off, and the salt will prevent brush from growing back in the future.
Vinegar and Dish Detergent
A combination of vinegar and dish detergent works to kill tall, leafy brush. The vinegar kills the brush, while the dish detergent works as an adhesive, making the solution stick to the leaves of the brush, which kills the brush more quickly. In a spray bottle, mix two cups of apple cider vinegar and four tablespoons of liquid dish detergent (any brand will do). Spray the brush, working from the tips down to the roots, and making sure to saturate the entire area. Repeat once daily for a full week, and the brush will quickly die off.
