Weeds in my decorative rocks

Mar 15, 2026 Last reply: 4 months ago 21 Replies

Hi All,



I have a cheat grass and other weeds problem in my decorative rocks.



Does anyone know of a nontoxic to humans and pets weed killer that will keep them away for five year or longer.



I have tried rock salt. The weeds seem to like it.



I have sprayed corn gluten per-emergent twice a season for three years now. It does nothing.



I spray with 20% vinegar and It does kill the little dears, but twice a year I get a new crop I have to spray again.



Death to weeds!

Glyophosate (Roundup) President trump wants to increase the production of it so you have a patriotic duty to use it.

I would use Roundup and see no problem if used as directed.

Last week I put down a premerg for Japanese stilt grass. I have a problem with it and crabgrass but it is said to sprout weeks earlier and if you pull it anytime it is growing there are seeds that will sprout so in order to completely control it several yearly applications might be needed.

Roundup usually kills everything but other herbicides and premerges do not which is fine if you want no weeds in your lawn. For bare earth, kill everything. I completely eliminated English ivy around the house for just mulch under bushes which were unharmed by Roundup.

Your choices are to use chemicals which actually work, or 20% vinegar several times a year.

It needs to be safe for pets and humans. And as far as killing weeds, my 20% vinegar is deadly.

I just want the weeds gone for good.

I do not mind chemicals as long as they are pet and human safe.

I wish salt worked.

I'd treat my gravel driveway with 10 % vinegar about 3 times per year - it took 15 - 20 minutes and cost a few dollars. The only drawback was the craving for french fries afterwards .. John T.

Yes, so are the lies of lower gas prices and no more wars a d stopping the Ukraine war in a couple of weeks. Sorry about your gullibility.

You can read what the EPA says a about glycophosphate. It is not that toxic or harmful.

Some law firms have made a big issue of the IARC carcinogen classification to make money off it. The issue is greatly exaggerated based on epidemiological data.

You know things are really off-the-rails when Marjorie Taylor Greene begins to seem like the rational one .. John T.

The city has tried various approaches to weed control on the public spaces including manual pulling, sheep, and I think parasitic insects that target the plants. In the end Tordon wins.

Hi Frank,

EPA gets it palms waxed.

Wife suffers from MSC/TILT. Can't have glycophosphate ANYWHERE near her.

Do you know of another non-toxic solution?

It probably isn't a permanent solution unless you torch them off frequently enough to kill the roots.

Anyone have an experience with "weed streamers"?

No and as a chemist, I use chemicals but as minimal as possible. Other solution is to pull weeds.

Even if you do kill the roots - those pesky things called _seeds_ will soon come along, doncha know .. John T.

In my working days I was responsible for thousands of safety data sheets. I would generally ere on the side of caution. Many are written for the substance in a mixture but caution on the side of the pure material.

For example you could drink a teaspoon of 5% acetic acid, vinegar, with no harm but if you tried to drink a teaspoon of pure acetic acid you would end up in the hospital.

Not that it is a bad idea to be cautious.

Our non-toxic solution was to move to a condo almost 9 years ago, where all the gardening is done by contractors hired by the Board. No more snow to shovel, leaves to rake, dead trees to fall on our house, etc. We priced-out what we had paid for home maintenance for the 2 years before we moved compared to what the HOA was for the same time period for the unit we purchased. We have only 9 square feet less floor space now but pay within $100/year for HOA compared to our annual maintenance costs were before we moved. And, in the almost 40 years that the condo has existed, there's never been a special assessment. We should have made the move years earlier.
