Vinegar Weed Killer
Vinegar weed killer is a cheap way to get rid of a large area of annoying weeds in a short time. If you always see unattractive weeds growing faster than your desired grass plants in lawn, you should do something to save your lawn. If unattended, a small amount of weed will spread quickly by snatching most the water and nutrients for you cultivated grass. Compared with the high price of the commercial herbicides, some home recipes using vinegar and water can help you save a large amount of money if you have a large garden.
You should prepare a container about one gallon in volume, and pour some white vinegar into it. Generally, the active ingredient in white vinegar is acetic acid which is the main substance helping you kill the weed. The acid contained in the vinegar should be at least 5 percent and the more the better. However, high volume of acid in the vinegar may be harmful to your skin. So, you should wear some protective gloves when manipulating them. The high concentration of acidic substance will help remove the water in a plant and make it die quickly.
Then some liquid washing soap or dish detergent can be added into the solution as well. These cleaning chemicals will remove the wax protection layer of the leaves and make it easier for the vinegar to penetrate into the body of the plant. Also, it can make the vinegar accumulate in the plant and maximize the killing effect. When applying the home-made weed killer on the weeds, you should avoid pouring them on the neighbouring plants. You may repeat applying the solution for several times until the weeds are completely removed.
