Excellent Job

I've used this for a couple of years now. It did a great job when I figured out how to apply it. I was originally treating an area and no. It does the job when you apply to the weed and cover the weed. It even took care of some weeds that had gotten way out of hand and were a couple of feet tall. I will definitely buy again.
Works if done correctly

This stuff works very well if you properly apply it. I find you need to spot treat the weeds themselves, not treat an entire area. Also, it very much helps if you do it when the weeds are stressed. I find midsummer works well, especially if there is no rain in the forecast.

had an ugly mixture of invasive weeds/grasses/crawling vegetation and sprayed entire lawn as directed and made a remarkable difference! added WOW as well as some chicken manure and lawn took off/weeds departed the premises! Grass is green and full. THANK YOU!
Very Impressed!

My husband and I are extremely impressed with the effectiveness of Iron X against dandelions. We dislike using other products due to the degree of environmental toxicity. We are very satisfied and are repeat customers for this product.

This worked really well on the weeds in my lawn, and the grass was greener where I sprayed the weeds than where I didn't. I used a bit more than recommended and within 3-4 days the weeds turned black and died. Did not work for crab grass though. I will buy it again next year if I need it.
Didn't work for me

I also made more concentrated than the instructions indicated but only maybe 15% responded. I still have a alot of weeds growing, dandelions and crabgrass.
Great product

Works really well, especially if the plant is thirsty. If you are able to cover the plant and then have 4-5 days of no rain that is best. Also, it kills dandelions on first application, but certain more hearty weeds need a second dose. This stuff even works on clover, which I find amazing. I have a tow behind sprayer, but using it in spot mode as opposed to broadcast mode works the best.
Works Great!

I mixed IronX just a little bit stronger than the directions, and found that it works great. Dandelions were dark the next day, then black and shriveled the second day. Amazing! Covering the whole plant seems to be key.
It Works

My lawn had become infested with little broad-leaf weeds. Last fall I applied Iron-X. In two days the little buggers turned black. I then weed-wacked them down to the dirt. This spring they are completely gone.
mix stronger than directions say

When I mixed Iron X! as directed it had not effect on broadleaf weeds. So, I mixed it by increasing concentration of product 10X. It killed the weeds in about 12-16 hours, but not detrimental to lawn. It even wasted several morning glories.
Spring weeds erased

The dandelions were rampant as well as other weeds emerging in early spring. Iron-X works great as long as you follow the directions - even coverage on and around the weeds. I am comforted to know the wildlife and pets are safe in our yard. I wish the containers were larger and sized so that 5 oz / gallon used an entire bottle (the containers are opaque).

Applied an application of Iron X waited 1 week and applied a second application. Weeds are still thriving.
