If you’re looking to maintain a weed-free garden without resorting to chemical herbicides, making your own organic weed killer at home is a practical and eco-friendly solution. Using common household ingredients, you can effectively manage unwanted weeds while keeping your garden safe for the environment, your family, and pets.
How to Make Organic Weed Killer at Home
Creating a homemade weed killer is straightforward and requires only a few simple ingredients. Here’s a basic recipe to get you started:
-
Vinegar Solution: Combine one gallon of white vinegar with one cup of salt and one tablespoon of liquid dish soap. The vinegar acts as an acid, the salt dehydrates plants, and the dish soap helps the solution stick to the leaves.
-
Application: Pour the mixture into a spray bottle and apply it directly to the leaves of the weeds on a sunny day. The heat enhances the vinegar’s effectiveness, ensuring the weeds absorb the solution quickly.
-
Repeat as Necessary: For stubborn weeds, you may need to reapply the solution every few days until they are eliminated.
