Q.Hydrangeas Not Blooming
I planted blooming hydrangeas last year. They were beautiful! This year the plant is looking very healthy, but it is June 29 and no blooms on either of my hydrangeas. They are planted in day sun and afternoon shade. The plants are on different sides of the house and still no blooms. I did not prune these last fall, is that why they are not blooming?

The soil around the non-blooming hydrangeas may be lacking in phosphorus. That can affect the ability of the plant to bloom. These articles will help you learn more:
