Awesome stuff! So far it’s the best product I’ve found to get rid of invasive Sierra Nevada weeds long term.

This is a great tool for weed control at organic properties. It will knock down most weeds although it may take several applications. If is also imperative to follow maximum safety precautions on the label. It will burn a hole right through your clothes or if in your eyes ruin your day. Excellent product!

I wasn’t expecting an organic product to work as well as glyphosate, but for the price, I was still expecting it to be reasonably effective. So far, that hasn’t been the case. I mixed the concentrate at the strongest recommended blend. I applied with a backpack sprayer to it to a wide variety of plants… everything from dandelions to blackberry vines. And I was making sure to wet the leaves with the product, not just sprinkle. 24 hours later, most of the weeds I sprayed are showing no evidence. Some of the weeds I sprayed look to be a little distressed, but that’s about it. The one thing it seemed to have the most effect on was our blackberry vines. It turned the tips of some of the leaves black, and they curled. But other than those few spots, the leaves still look healthy. With the results I got, I won’t be buying it again. See the images I posted. Maybe the weeds will continue to die back, but the instructions say that they’ll start dying within 1 - 2 hours. They don’t look any more dead now than they did yesterday.

Works great and love that I feel comfortable using this product around my kids and animals. It's been difficult to get this year.

I bought it to try before investing in the concentrate. Works really well but, as expected, the spray bottle doesn't go very far. This should really be sold as just a sample size of the concentrate. Same product pre-mixed. Works best for me on clear days over 80 degrees.

This is a safe and fast acting product. Hard to find but worth the wait

This product works like crazy after 25 minutes. You can see the weeds shriveling. I use it on two properties to maintain the looks of each.

Wish you guys still have the 2.5 gallon container. Otherwise rather expensive.

We’ve tried many non-glyphosates (screw Monsanto). Finally, one that works

It is an effective weed/grass killer. It is quick, killing overnight. Great product!

I’ve had plenty of success with the spray bottle form of Mirimichi but my recent experience with the concentrate was totally different. I mixed and sprayed at the appropriate rate on the label 3 different times and it did not kill the target plant. Would love to know if plants are capable of building up any kind of resistance to the herbicide.

Love it. Wish I had found it earlier

Works pretty well. Like that it’s not Roundup.

I was introduced to this product app 10 years ago by one of your salesmen, along with a couple of other products. I was happy with the results and used it for several years. Recently we have had a renewed need for the product due to some changes in our property. I have received the organic herbicide but haven't had the chance to use it because of some weather challenges but plan to do so as soon as possible.

This is the best natural product I have ever used. I've noticed that areas that were treated did not allow regrowth for quite a while, and works fast. Compared to other products the smell is not to bad The only problem I've found is the bottle sprayer. It loses pump pressure alot and leaks. Thank you for a great weed killer.

It really helps us keep the weeds out of the garden and is a great alternative to round up

It does not kill the crab grass and the weeds.

Sent the wrong product and have been horrible to fix the issue
John P. 1/5 Verified
This was a waste of money! Not only did it NOT kill weeds, it only turned each individual spot where it was sprayed..brown. It didn't kill anything! Not even the leaves that were sprayed died, the unsprayed portions of the leaves just stayed green and was no different than if a little bug chewed it..

It is a challenge to keep back grass and weeds from walkways and garden areas. I have tried many different products including RoundUp which must have changed the composition of the chemicals used, because it now ranks among the lowest grass/weed killer I have used. Mirimichi Green was recommended to me, and I purchased some online. The first time I used it the grass and weeds were 90% dead. One area was very thick, and it required a second dose. I was so impressed that I went out and bought another 2 bottles of the spray. Thank you Mirimichi Green!

It just didn’t do too terribly much for my weeds. At the price point, I’m not sure it’s worth it

Awesome product. Does the job safely and organically.

Never had a weed killer work so fast, and they don’t come back! Might seem expensive but you don’t need much,I wouldn’t use anything else from now on!
Tim L. 5/5 Verified
Works as advertised. It’s pretty incredible to see a plant wither almost in front of your eyes. The down side is that it works on my bermuda grass as well. So I can use it as a spot treatment but not as broadcast.

Best Weed Control Out There I use this in my garden, flower beds, between the stone pathway, along the fence line, and really anywhere that has weeds. I'm always amazed at how quickly it works. I've seen it start turning weeds brown within an hour on hot days. I've even used it on weeds that aren't mentioned on the label like poison ivy and have had success. The best part is that it's organic. I don't have to worry about family or pets being exposed to nasty chemicals. I won't be using anything else from now on! Customer for life!!

Leaky spray bottle. Think the material is good, but a leaky bottle has me wondering about quality control!
Kevin W. 4/5 Verified
Bought this product two years ago, and it works exactly as described. Unbelievable! I recommend this product to anyone who wants to spray a weed and it dies in a minute. Never harmed my other plants. Best of all it is organic and lasts for a long time. Just now needing to buy more!

Best weed killer that I have found. Mirimichi Green kills weeds and unwanted grass quickly and does not remain in the soil.

Another great product by Mirimichi Green. The product works well and quickly and gives me peace of mind that it is organic.
