Weeds are a perennial challenge for most gardeners. Many options exist for weed control, ranging from strong chemicals to more environmentally safe alternatives. If you want to control weeds in a garden or flower bed and want to do so naturally, there are effective ways to accomplish this. For best results, start with prevention. Mulch with a weed barrier and then another layer of organic mulch. If weeds push through these preventative layers, make a natural weed killer to control them.
Lay down newspaper or fabric barrier in areas without plantings to prevent as many weeds as possible. Cut the fabric barrier with scissors to make it fit your growing area and cover the entire soil surface.
Cover the weed barrier with at least 2 inches of organic mulch to further prevent weeds.
Pour white vinegar (full strength), lemon juice concentrate or boiling water directly onto weeds at the roots. Use a glass measuring cup and pour between 1/4 and 1/2 cup of the chosen liquid onto each weed. Be careful not to allow any of the liquid to splash onto nearby plants that you do not want to kill.
It is important to allow the liquid to soak into the roots. Allow 24 hours for the herbicide application to work. Repeat after 24 hours, if necessary.
