Got my yellow azaleas back to green and looking great this past summer. Bought the larger jug the 2nd time. Cheaper on Amazon than at the nursery who recommended it. Easy to mix and apply, used on soil and leaves. Works well!

Quick acting on soil. It is so much better than bagged acidifiers - a whole 5 lb. bag of Espoma brand can't even touch what a little of this does. You don't need nearly as much to do the job. Obviously it takes the plants a little time to right themselves once you fix the PH. I use Earthboxes for most of my veggies and even the Peat based potting mix is never the right PH. It is usually too alkaline, especially the Canadian peat, and is likely why many people don't get really good results in grow boxes or pots. Even seedling mixes are off. It never dawns on people to check PH. It can fix alot of issues and it is so simple. Everything you amend potting mixes with can alter the PH. I found even my water is pushing a PH of 8 and obviously affects potted plants with regular alkaline waterings! So, get a combo PH, Moisture and Light meter to check your plants. You'll be amazed how easily they fix themselves once you correct just the soil PH. The meter helps you with watering issues also - no more over watering. I just got 3 more quarts of this to prepare for spring - I use it around my fruit trees and shrubs as well. Love it.

Easy to use and makes your garden more acidic. Don’t follow directions though. When I added it to water, I saw no results. Poured tablespoon worth directly into ground and worked like a charm

Good for the money, goes a long way

I use this for my Blueberry plants. When the acid thermometer starts to turn out a little bit of a higher pH, I use this product to reduce the pH back closer to 4. I baby my blueberry plants. They have slow release acidifier & I keep them mulched with Pine Bark (acidic). They produce an enormous amount of delicious berries every year.

I love this stuff. My hydrangea constantly had pale green leaves (bad soil) but as soon as I started using this, their leaves were dark green, flowering more often. Noticeable difference.

Game changer. I did the 2tbls. in a gallon of water. I tried it on a sad looking weed first to make sure it didn't kill it on the spot. Turns out it was a Cherry tree growing from a pit we had opened up... and it was standing up all strong and happy. I had splashed the base with water and then the Iron mixture and then water again. Making sure nothing would get burned. Since the cherry tree worked without dying over night ..I tried it the same way on my very yellowing citrus and after two weeks I did it again . It doesn't happen over night but after a month I have very healthy looking potted citrus...Lemon, orange and tangerine. When fertilizing wasn't working I tested the ph. Usually I give them new soil before winter starts and everything gets healthy again but this sure helped. Meyer Lemons can be FRUSTRATING. This was a sweet game changer. Only used it twice. Everything keeps getting greener.

My acid-loving, phosphorus-sensitive plants love this product! Purchased 3 times now…and will again for sure. Great product and arrived a few weeks ahead of schedule!

Works better than any product I’ve tried and a little goes a long way. Super happy I found this
