Rated 5.0 out of 5.0 by jj very good Product
I just used it on 8 blueberry bushes. I hope that it will be OK. The soil looks very good, One third sand, one third peat and one third soil from Home depot.

Surprised at how effective this product worked. Just one application and my hydrangeas were turning from pink to purple to blue.

Rated 5.0 out of 5.0 by HAFNERA WORKED BEAUTIFULLY
I use a service to fertilize my garden. They do an excellent job but not for plants that need acid soil. My wife objected to the fact that our gardenia had very few and very poor flowers. I set out to buy garden sulphur but couldn't figure out what I would do with 20 pounds of it so I settled for soil acidifier with which I was unfamiliar. The results were amazing. It's been about 2 weeks and the sad looking yellow leaves are green and there are blooms and lots of buds.

6 lb. Soil Acidifier works well to lower pH of our soil to enhance blooming and color of acid loving plants

Rated 1.0 out of 5.0 by Roughrider Didn't move the needle at all
With tested soil alkaline level at 8, I needed to acidify my soil. If the product would have just taken my soil to 7, I could have added another bag to get to my desired 6-6.5. After one week of normal watering after application, we didn't move the needle at all on our PH meters (testing always with 2 meters).

Easy to apply. We have to wait for the flowers to see results.
