Works well
This fertilizer did what I bought it for, change the color of my hydrangeas to bright pink! Worked just like expected. I have three large bushes, this bag will last me a very long time.

Will last a long time, but it works great!
This bag is going to last an extremely long time. I used this to make my own starter mix and have had excellent results with growing my watermelon, pumpkin, tomato and lemon seeds! My recipe: Approx. Quarter pound of spagnum moss, 1 brick of coco peat, 1 cup of vermiculite and 1.5 Tbs of garden lime (to neutralize acid levels of spagnum moss). I just mixed these all together and soaked the mixture until it was all damp before putting in the baskets. Some people use just the coco peat bricks and vermiculite, however the spagnum moss is cheaper.

Works swiftly and accurately
I was sold soil that was too basic. This acidifier dropped the PH exactly where I wanted it. I went from 7.5 to 5.5 on the pH scale exactly where I need it for blueberries.

Good product so far
Used it couple of times as instructed and no issues so far. Plants are growing well. probably needs another update in couple of months to see the actual results for the color.
