I try to find green products for more than just house cleaning to recommend, and I recently tested Bradford Natural Horticultural Vinegar from Planet Natural (here is the vinegar link) on sidewalks and driveways, as well as gravel mulch and bare soil around plants. Here is the description on the website:
Kills weeds fast! Bradfield Horticultural Vinegar is inexpensive and environmentally safe — perfect for organic growers! Contains 20% acetic acid and includes yucca extract — a natural surfactant and penetrating agent — to completely cover weeds and undesirable vegetation. Works fast (within a few hours) and degrades quickly in the environment.
• Will NOT harm people, pets or wildlife
• Contains 20% acetic acid (household vinegars contain 5%)
• Safe to use in gardens, lawns and landscaped areas
• Will NOT travel through the soil to injure nearby plants
• May be used for pH modification of soil and water
• Made in the U.S.A.
$22.95 per gallon
See the keywords there are Will NOT harm people, pets or wildlife, which is good because the news about decimated bee populations and concern about pollination of crops has a lot of experts worried.
Result: What I found was that it works as described. It works much faster and more effectively on the harder surfaces – within hours! The vegetation in the soil areas that I sprayed, were dying out by the third day. In all areas the plants and shrubs I wanted to keep, appear to be unaffected after a week. There is a very strong vinegar smell for an hour or two afterwards, so don’t do it just before a garden party.
Here is a log of my process on The Cleaning Authority facebook page.
The Cleaning Authority Macomb Okay, I just sprayed my driveway and sidewalk weeds that I usually pull by hand. Visitors stopped by and said it smelled like vinegar. It’s been a couple of hours, so I’m going outside to see if it still smells. Won’t know if the weeds are going to die until tomorrow probably. I have to keep reminding myself that I’m doing this for the bees and the vast majority of crops that depend on pollination.
Linda Curatolo This product absolutely works to kill the plants, and the vinegar smell was gone within a couple of hours. By the next day the plants were just as dried and shriveled as if I used roundup. Question remaining: how long will it suppress new weeds from coming up? Stay tuned.Bottom line – there are at least two households that will use this product and a whole lot of beneficial creatures such as bees and birds that won’t be decimated by toxic chemical herbicides. Thanks, Mom for being such a good sport. And thanks, Planet Natural for the suggested product!
