Is there a natural weed killer that will not kill grass?

Hi Nanci! I am a chemist, so I would love to help you. Natural weed killers cannot be formulated to kill weeds but not harm grass unfortunately. All the homemade or natural versions will kill just about anything growing. I do recommend making sure your grass and soil are very healthy which will choke out weeds overtime. I use our DIY Lawn food which nourishes soil and helps grass to grow strong.

Hi Nanci! I’m a chemist, so i would love to help. Unfortunately, natural or homemade weed killers cannot be formulated for specific types of plants. Here is more details under the lawn section: https://chemistrycachet.com/easy-homemade-weed-killer-2/

Lawns are not safe with DIY weed killers, they will also alter the chemical composition of the soil so that nothing grows.
