I was with a friend the other day and we were talking about gardening plans – mine is just to get some plants in some pots and try to keep them alive until August, while my friend’s plans are much more expansive. Also, she uses all organic materials, while I am a lover of Miracle Grow (I need all the help I can get). She was wondering if there is a natural, non-chemical way to kill weeds on your lawn. I promised her I would do some research and get back to her.
The good news is, there are some easy methods you can try to kill lawn weeds with household products that are probably in your kitchen. The bad news is they aren’t guaranteed and they will kill the grass around the weeds you are treating unless you create a barrier with cardboard tubing around the weed or cover the grass around it with plastic. Also, make sure your lawn is dry and there is no rain in the forecast for best chance at these natural remedies working.
Here are a few things to try out to take on those weeds:
Boiling water: Cut off the top of the weed and pour boiling water directly over the plant to kill the roots and the seeds. Continue daily until you see results.
Vinegar: Put some white household vinegar in a spray bottle and spray weeds weekly until you see results. You can also add a tablespoon or so of dish soap to the spray bottle to break down waxy weed leaves. Special horticulture vinegar is stronger and may be more effective – you can buy it at most nurseries.
Salt: Sprinkle a few pinches of salt at the base of the weed weekly until you see results. Wait at least a month to plant grass as salt adversely affects the soil.
Alcohol: You can use rubbing alcohol or drinking alcohol (ie gin, bourbon, etc.) to spray your weeds – add 5-10 tablespoons to a quart of warm water and spray the weeds thoroughly. The alcohol dehydrates the weeds – repeat daily until you see results.
