Why doesn’t my hydrangea bush bloom?

Question

My hydrangea plant has grown bigger every year, but it does not produce the blue snow ball flowers its supposed to, why?

Answer 1

These will, more than likely, produce white flowers, unless you use chemicals to turn the flower color. Here is an article to explain: https://www.gardeningknowhow.com/ornamental/shrubs/hydrangea/change-hydrangea-color.htm

Now, the reason it is not flowering, is more than likely that it needs some fertilizer high in potassium, and phosphorus.
