It took me about a month , fed it once a week and I might have cheated and fed it twice a week sometimes, I have little patience. I bought a beautiful purple Hydrangea a few years ago, but it eventually turned pink over the years. It’s more purple blue, my hydrangeas nearly doubled in size with gorgeous blooms!

Should’ve used more for full effect but it is doing what it supposed to Definitely works!

I'm super impressed with this product. By using this product at the beginning of this year 2022 the flowers have grown back purple, it looks even more purple than the photo, I am very pleased And you have to keep applying it throughout the flowering period.
