There are several effective methods to control weeds without using harmful chemicals, including:
Hand-pulling: Hand-pulling weeds is an effective way to remove them from your garden or lawn. Be sure to pull the entire weed, including the roots, to prevent regrowth.
Mulching: Mulching can help prevent weeds from growing by blocking sunlight and reducing soil moisture. Use a layer of organic material, such as leaves or straw, to cover the soil around plants.
Boiling water: Pouring boiling water over weeds can be an effective way to kill them without using chemicals. Be careful not to pour the water over desirable plants.
Vinegar: Vinegar can be an effective natural herbicide when applied directly to weeds. Use caution when using vinegar, as it can also damage desirable plants.
Corn gluten meal: Corn gluten meal is a natural product that can help prevent weed seeds from germinating. It can be applied to lawns and gardens in the spring and fall.
Cover crops: Cover crops can help suppress weed growth by competing with them for nutrients and sunlight. Planting a cover crop such as clover or rye can help keep weeds under control.
