Espoma Organic Soil Acidifier Soil Amendment; Lowers Soil pH and Turns Hydrangeas Blue! Contains Elemental Sulfur and can be Used for Organic Gardening 6 lb. Bag - Pack of 1

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.

Tried and true acidifier, Amish use their products routinely.

It works on one of my Endless Summer, but not for another. Cause, I have many rose, it still a good fertilizer for my garden.

Good product. I need it to repair ph level for my rhododendron plants.

Last year I tried a little initially, trying to change my Pink Hydrangea to bit blue, it was sold to me as a multicolor variety but always gave pink flowers and had been growing very well. Nothing happened, so tried a bit more and nothing. In the end I ended up dumping the whole 6lb bag and saw no change.This season have of my Hydrangea is blue/purple/pink and other half is all pink.I just put down another whole 6lb bag. Its so release but works

The applications are easy and the results are positive.My dwarf tangerine tree kept dropping its fruit. Plenty of blossoms, fruit set, but soon fell off. Leaves and new growth were fine. Husband said if it won't produce fruit, it's too much trouble to keep shifting indoors in winter and outdoors in summer. I agreed. But before we ousted the poor plant, I did a soil test and then researched the preferences of the plant. I found out that the pH was too high and getting worse. After one application of Soil Acidifier, in the winter, I had hope. After the second application 3 months later, the plant set fruit and has kept them (the largest is now the size of a golf ball). Next application will be in two months -- by then I'll probably be eating tangerines.

I have used this twice and the soil doesn't seem to be changing much, not becoming acidic as I thought it would. PH same as before I used it. Maybe I'm not using it correctly. I do mix it with the soil around my acid loving plants.

I bought this because I noticed leaves on my blackberry were yellow. All the instructions said it would take at least 6 months to get the soil fixed up and my blackberry was in bloom and (hopefully) setting berries. I put it out, ran the sprinkler and it rained. I can't say I got it nicely around the base of the plant, this is a huge blackberry bush and, to be honest, I kind of tossed it through the plant. It's been about a month now and most of the leaves that were yellow are now a healthy color, it's setting berries like crazy and looking very happy. I will apply again this fall, as directed, but expect all to be well, including this season's crop!
