Jack's Classic 7-3-3 Hydrangea Blue Water-Soluble Fertilizer with Micronutrients to Enhance Blue Flowers, 1.5lbs

Not only were the new blooms more blue, there were many more of them. Never had so many blooms. Even my landscaper remarked that he had never seen such prolific hydrangea. All I did was sprinkle some around the drip line of each plant. God did the rest.

I have been using this for about a month & the soil where I live does not facilitate blue hydrangeas. This is the result of using this product & it's amazing!!! I tried other ones & this is the absolute best!!

I like these products but disappointed I still have pink hydrangeas. It may take time to change the soil ph since I recently moved a couple

Item as described. Have not been able to use it yet because it won't stop raining. I'll get to it soon. I expect it will work as described as people have made great reviews on it.

Three stars because of the brand. I like this brand for its basic all in one fertilizer. And although my hydrangea looks super healthy, It’s far from the blue/purple flowers that it had when I purchased it last year. The color of the pot it’s in was actually the color of the flowers when I bought it. The one I already had has beautiful pink ones and I’m fine with that. The one that was purple/ blue last year was coming out with new buds that had not opened yet. And looking at them, they had a bluish color. Just to make sure I ordered this trying to get it as soon as possible because the granules you put on top of the dirt take a while to work and they were hard to measure for a pot, so I just used those purchased hydrangea granules around some of my trees and waited for this which took an entire week to arrive. I doused it immediately with the first treatment when it arrived and as the blooms that opened are pink?? It said to redo in two weeks but I doused it again…and again with another treatment, hoping it will change it . I thought that especially since they were blue last year, it would be easier to ensure blue flowers. The pink flowers became a darker pink, but that’s it, and now it’s been a couple of months so not impressed unfortunately.

Apparently this stuff works well!

Beautiful hydrangeas after feeding with this!!!

Without this, my hydrangeas are pink. With this, the range from a purple to a dark blue. Easy to use.
