Rated 4.3 out of 5 by 10 reviewers.
Rated 5.0 out of 5.0 by Works like no other. I have used alot of products to green up my lawn. This Dr. Iron works like no other product. I got the greenest lawn out of the neighborhood. You can't go wrong using this product at all. You apply it and water and thats it. Give it about two weeks or less to see results. Turns that yellow grass into the greenest. It doesn't burn your lawn at all. I recommend this product to anyone. I will buy again and again. May 1, 2013
Rated 5.0 out of 5.0 by Excellent Product!!! This product was super easy to apply and it didn't leave any stains on the concrete. The best feature is that is organic, so it is safe for kids, pets and the enviroment! I saw results after one week. The yellow, necrotic grass (St. Augustine) turned green and beautiful... I'll for sure keep using this product and recommend it. October 9, 2014
Rated 5.0 out of 5.0 by dry lawn patches after some online research i decided to use dr. iron on a few spotty dry patches in an otherwise green lawn. within 4-5 days the dry patches had improved to the point that the rest of the lawn was able to spread. for my lawn (Bermuda) ...i'd recommend and will keep a bag on hand.

Rated 5.0 out of 5.0 by Great Product My lawn was turning Yellow i believed for lack of Iron in the soil as i live in an area with very Alkaline soil. The Dr Iron Lawn pellets were easily spread with a Hand spreader and completely disolved into the soil within a week. The lawn is starting to green up even amidst a record Breaking heat wave and none of my concrete was stained in the process. July 16, 2013
Rated 5.0 out of 5.0 by safe and effective product I was looking for a product that would effectively green up my lawn and help control fungal disease / brown patches. This product has done a wonderful job and one bag covers 6,000 square feet and lasts up to 29 weeks which is an added bonus. I also needed a product that was safe. And unlike Ironite (which has had multiple studies and has been show to be extremely hazardous to your health) this product is safe to use and does not break down into Arsenic like Ironite does. It is also made from organic materials and is certified to be organic. So from the safety factor to the fact that you can get so much out of a bag (6,000 sq ft worth) and it last for a long time makes this an obvious choice. And most importantly, it works very well with just one application. The only downside is that you cannot buy this in a home depot store, it is an online item only. I hope they decide to carry it in their stores soon! April 20, 2011
Rated 5.0 out of 5.0 by Greener Thicker Grass The lawn is like a carpet and is definitely more lively than years past. June 11, 2013
Rated 5.0 out of 5.0 by Killed moss in yard after first rain. Yard turned bright green and it killed the orangish brown moss after the first rain. Looks good so far. April 17, 2013
Rated 5.0 out of 5.0 by Dr Iron took care of the problem I live in Florida on the west coast where the soil is higher in ph. The small area where I put in lawn in was turning yellow. Had put nitrogen on but didn't change much so used this to bring down the ph and now starting to see a difference. Its been on for less than a month and is greening up and looks healther. Was wotth the money and time. Gary December 18, 2012
