SO, if you know me at all, you KNOW I love the color blue. It is everywhere! A few years ago, I bought a bunch of beautiful blue hydrangea bushes and planted them around the house. Only problem is that this year they are all turning up PINK! Not that they aren't lovely, but still.. I want them to be blue! SO, I found this product at our local garden store. Going to give it a try! Has anyone ever used this? I will keep you posted on how it works out!
