What Customers Are Saying

Customers overwhelmingly praise the product for rapidly greening lawns and improving plant health, with most noting visible improvements within days. Many highlight the convenient hose-attachment design and ease of application across lawns, shrubs, and flower beds. Reviewers frequently report dramatic transformations from yellow or patchy grass to lush, vibrant green, especially in hot climates. However, a notable group reports sprayer clogging or uneven dispensing issues that prevent product use. Despite this drawback, most customers remain highly satisfied and recommend the product for its effectiveness and simplicity.

did nothing

Would Not Recommend

I tested my soil first with a test kit and it was very low in nitrogen. I applied the whole "treats 5000sf" bottle to my 600sf yard and waited 2 weeks. The grass didn't get any greener and the soil test still showed very low nitrogen.

WORKS IF PRODUCT STRAINED/NOZZLE HOLE CLEANED!

Would Not Recommend

Product crystallizes sitting on shelf and will prevent solution from siphoning up tube. Take sprayer head off bottle, pour product through a fine strainer, rinse bottle out well, pour strained product back into bottle, ,pull siphon hose off spray head, clear clogged hole on head with paper clip while in the ON position, put spray head back together, and now the product will work as advertised. Will I do it again? NO!

Waste of money - POOR customer service

Would Not Recommend

Instructions on the bottle are useless. Makes no sense to have both a water setting and an ON setting without explaining the difference. Customer service does not provide any help either.except their canned response of "Oh we're sorry, call us if you have questions!" Buy something other than Pennington Ironite.

Liquid Ironite

Would Recommend

I can definitely recommend this product and would say those that are having issues, maybe the bottoms was broken beforehand I have never had an issue with product and always works as should. Yard showed signs of deep greening in about 5-6 days. I watered day before application and the afternoon after applying.

Do not buy this ... the sprayer doesn't work

Would Not Recommend

I tried 3 time to spray this on my lawn. Nothing worked. I took the cap off and made sure there was nothing blocking the suction straw. I pushed a nail through the hole in the cap where it is supposed to inject into the hose spray. After 3 times (45 minutes of spraying) I still have a full bottle. Total waste of time and money.

I will buy this product again

Would Recommend

A lot of reviews on the container not working. Not sure if I have just been lucky but never had an issue. If anything be careful because the container is designed for up to 5000 square feet and you don't realize how much product you are putting out. Easy to over apply. Never had any issues, 1st try I applied 4000 square feet worth on 1000 because I thought it wasn't working. GREAT PRODUCT!!

Sprayer defective

Would Not Recommend

The sprayer would not mix product with water when turned to the correct location. The product is great but the sprayer is defective. I have a sprayer full of Ironite that I can not use. The cap is tight and the siphon tube is attached.
