Review: More environmentally friendly that Roundup, works on many annual weeds and grasses - Here in So Cal, weeds follow rain like clockwork. And since there was an untended lot across the street from me, I have about 15 years of weed seed accumulated in the soil. In addition, I'm trying to install a drought-tolerant native landscape, which requires that I clear the front yard first. Digging out weeds and grasses turned out to be a never-ending task. I have tried many different options, including hand weeding, various "organic" weed killer, flame torch, and glyphosate and decided to try this one. First, it is not OMRI (organic gardening) certified. But being a chemist, I researched the online Safety Data Sheet and found that it is mostly C8 and C10 saturated organic acids, which can be derived from coconut oil, with 20% "other" (nonlisted, therefore presumably non-hazardous surfactant). According to what I can find, the active ingredients are non-cancerous, not persistent, and do not bio-accumulate. That's a plus. Taking a cue from other reviews, I mixed it at the higher concentration and sprayed it on a variety of emerging and established weeds and grasses. First of all, it works really well on most newly-emergent weeds and grasses, including spurge, foxtail, and oxalis. It coats leaves evenly and - unlike glyphosate- "burns" them quickly, so I can see in two days where I missed, and re-spray where necessary. It does NOT work on established grasses, even tho I saturated some clumps thoroughly, and does NOT work on common mallow. Because it only works on leaves, and not seeds, it must be re-applied on each new crop of sprouting weed and grass seeds. But because of the nature of this weed killer, I feel more comfortable re-spraying, and with each application there are fewer and fewer sprouts to contend with. Overall, this spray will make clearing the yard much easier, and reduce the amount of hand-digging by about 70%. It IS pricey, but because of the combination of positive qualities and the amount of work it will save, I feel it's worth the cost.
Review: Thorough and fast working - I’ve been using this product for a couple of years now. Works great! It also works super fast. Just don’t spray it on anything you don’t want dead.

## Questions & Answers

**Q: Will this hard flowers such as iris and daylily? Or fruit plants such as fig and brambles (raspberry, blackberry)?**
A: I sprayed it around bulbs and they were fine. But I sprayed it around ground cover plants & it ruined them.

**Q: Does Deadweed Brew kill the roots of weeds it's sprayed on?**
A: Some persistent weeds will need more than one application to kill the roots, but visible plant damage is easily seen within a day.

**Q: Where can I find the instructions for this item online  (since none are provided in this product listing)?**
A: The instructions are attached to the container when you purchase the product.

**Q: At full concentration how many sq ft will 32 oz cover?**
A: It kind of depends on how thick and high your weed cover is.  I used almost all of the 32-ounce bottle and covered about 50 feet of pathways and a 15 X 20 patio area.  You have to apply it pretty heavily but it works!  There are a few pesky weeds that try to come back but keep hitting them.

### ⭐⭐⭐⭐ Kills most weeds in my vegetable garden
*by W***Y on January 1, 2026*

I use this weed killer in my vegetable garden as it is organic. After steady rains, the weeds start popping up in my vegetable gardens and has fast same day results. I refuse to use chemicals around the vegetables I eat. This concentrated formula is cheaper and more effective than high concentration vinegar making it a good value for my money. You need to keep shaking the spray bottle as the plant oils separates from the water solution. It is non-selective so you need to be careful with the over spray. It has a strong odor but it goes away after a day or two.
