This is so far the best soil acidifier I used. It's slow released, mildly adjust the PH level of the soil. My rhodie and gardenias are loving it!

Have applied as directed to new blueberry plants and monitored with pH meter. Soil pH has not changed over the summer. Tested a sample by dissolving it in water. No change in the pH of the water. Very disappointed in this very expensive product.

This product works great. I applied it to a blueberry bush that was not doing very well and it completely turned it around. The bush went from a few branches to full growth. I have since done all my other bushes and the amount and size of the berries is just fantastic. I have purchased more for the coming season, looking forward to lots and lots of berries and healthy bushes. Would definitely recommend this product. A little goes a long way.

The plant food is granules that come in a container with a dispenser with holes in it. All you have to do is shake the granules around your plant. I use it for my blue hydrangeas and they produce that beautiful purplish blue color that I love. Follow the directions on where to put the plant food. It directs you to put it on the drip line, meaning the outer ring around the end of your plant's stems.
