Earth’s Ally Weed & Grass Killer is a non-selective, ready-to-use herbicide. Powered by sea salt, it quickly kills common weeds to the root and offers a safer alternative to harsh chemicals when used as directed. Earth’s Ally kills common weeds, including broadleaf, crabgrass, dandelion, clover, ivy, chickweed and many more. When used as directed, Earth’s Ally delivers visible results in 3 hours and has been proven to kill weeds to the root, so you won’t end up treating the same weed repeatedly.
Directions for Use

For best results, use Earth’s Ally on a dry, sunny day. Shake the bottle to thoroughly mix the ingredients and saturate the weeds you want to eliminate using the stream setting, not mist. Apply generously to both the leaves and base of the weed so the sea salt makes its way to the root. Do not use during rainfall or when weeds are wet. Avoid overspray on desirable plants.
I live in south Florida. Weeds in my yard are a constant problem, and the weeds down here are very resistant to weed killers. This one works on some, not on others. This product will kill soft stem weeds and grasses. However, most weeds down here are hard stem and are not going to be affected by this product. I would recommend this to homeowners in the northern areas. As you can see by my pictures, there are some weeds that have had absolutely no adverse affects and others that it killed quickly.
I use other brand name products that are to do the same thing, kill vegetation. They don’t use sea salt as a means but a more harsh chemical that could be a carcinogen if not used with the right protection. This product, because it doesn’t have those kind of chemicals, was appealing. I did a couple of test spots to see how it worked for me. It worked okay but I needed to treat the grass I was testing twice to get it to work. I know that’s not the case with the other products thus I discounted the stars. I didn’t have any more difficult weeds to test but question if this product can handle the really tough weeds. I’d wished the product would be designed to go after grass and not other plants like shrubs. That would seem to be a better fit for this product.
I must admit I was really excited to try Earth’s Ally Weed and Grass Killer. Having a product made in the USA, bee safe, and more environmentally than glyphosate is important to our family. Unfortunately, I didn’t get the results I was hoping for. I soaked the weeds and grass along one of our fence lines three times. Each application was 2 to 3 days after the last application. I made sure to shake the bottle well before using. Each time I sprayed was in the afternoon with temperatures in the 90s. Some of the grass and couple of broad leaf weeds have turned slightly brown but none of them are dead.
I have mixed feelings about this weed killer. It seems to work, with the caveat that if it rains after applying you’ll need to start again. That’s what I’ve been running into while trying it. I’d apply Earth’s Ally earlier in the day and then later in the day it would rain. When this happens, it washes away and stops working. I always compare weed killers to Roundup. Earth’s Ally is safer for the environment than Roundup, and that’s a good thing. But if you want something that consistently kills weeds, even under less than ideal conditions, Roundup still works better. I sprayed a patch of weeds in my driveway with Roundup on the left and Earth’s Ally on the right. Both started killing the weeds. Then that evening it rained. As I monitored the area I found that after the rain Roundup kept killing the weeds but Earth’s Ally washed away. So take home message is that it works, but you have to make sure things stay dry or you’ll need to reapply.
I sprayed Earth’s Ally weed and grass killer in areas of my garden I was hoping to get rid of a few weeds, easier.
I applied this to the weeds at the hottest part of the day, as instructed. I waited one day. No noticible changes or dead weeds. Application #2, still no significant change. The product works with the aid of vinegar and salt. For me, I couldn’t recommend. I saw no real weed killing. It works on fine grass.
