Erin SheehanWeeds overrun our property in June and July. All around the garden fence and in the driveway cracks, weeds grow out of control. We spend hours pulling them, and a day or two later we’re right back where we started. We don’t like to use Round-up or things like it so Jim did a little research online for non-toxic weed remedies.


First Jim read that straight-up vinegar will kill weeds when applied directly to the foliage. I don’t know if any of you have tried this but it did not work for us. The weeds grew unabated after repeated vinegar applications. Back to the drawing board. Jim then found this recipe:

Homemade Weed Killer

1 gallon white vinegar
2 cups Epsom Salts
1/4 cup Dawn dish soap

Put all ingredients into a sprayer and thoroughly soak plants on a warm, sunny day. Be careful to use this on a day when you don’t expect rain for at least 24 hours.

Does the dish soap have to be DAWN or will any dish soap work???

I love, love, love this stuff. I talk about it to people who need it. Works like a charm, every time I use it. Thank you, thank you, thank you.

To kill weeds that are NOT next to flowers you grow, or veggies, nor anything else you wish to remain unharmed, I use rock salt...or more precisely, water softener salt without any of the additives. the main thing I use the salt for is my driveway. I'll water it down really good, spread the salt, then a wee bit more water to help it dissolve & soak in. I never have any problems with weeds in the driveway. FOr other areas, I have goats & chickens that take care of those areas.

Be careful where you spray--it's an equal opportunity killer.

One thing I found out long ago, was that salt kills plants & it does it without hurting the environment. For a driveway that is infested with weeds, go to your local grocery store/farm store 7 buy salt pellets...ones without additives. Spread a layer of these pellets across the drive, ently water it down enough to make everything wet, then let nature take its course.

Erin, awesome. A non roundup week killer is just what I need. This year has been a cool wet year. The soil has never really dried out and weeds abound. My planting this year has been mud planting for all the plants except the ones in the buckets. I too have tried vinegar without success. I have used a plumbers torch to scorch the noxious weeds. That works pretty good. I learned that one does not need to burn the weeds up but just over heat them enough to kill them. That works on a small scale but with large areas a weed dragon would work better. ***** Have a great weed control day with the non toxic weed killer.
