Eco-Friendly Weed Killer
One of the best way to kill weeds, without hurting the environment, or the critters in your garden or yard, is to use boiling (or hot) water.
Just heat the water up on the stove, and depending on how many weeds you're looking to kill dump the water, or pour it into a spray bottle and soak the weeds.
However! MAKE SURE you're careful with this method, as it will also kill all of the plants you WANT to keep.
