How can I buy the Bloomify fertilizer you show on your website?
The key with fertilizing hydrangeas is to choose a granular, slow-release formula with a higher percentage of phosphorous (that’s the middle number in the NPK ration you will see listed on the package) than the other elements. Phosphorous promotes flower production. Any brand will do. Ask one of the employees at your local nursery and they should be able to help you find some. If you run into any questions on how to use the fertilizer once you pick some up, watch this video for more on fertilizers and soil amendments.
