Hydrangeas Not Flowering

By

My hydrangea is 15 years old and it is this year that it has so many blue blooms on it, as I put the used coffee grounds on top of the soil all spring. All this time, it always grew healthily and had beautiful green leaves but hardly any blooms. The only thing that is different this growing season is that here in zone 4, we had a very unusual rainy spring.

We recently had a plant specialist speak at our local library, and someone asked the same question. He mentioned that there are many hydrangea that bloom only on "old" wood and that if your plant dies back each winter then you will have lots of new foliage, but no blooms. There are new varieties being marketed that supposedly bloom on old and new wood. Hope this helps. We live in zone 5.

I was given a potted hydrangea from a florist shop for Mother's Day about five years ago. I planted it in our yard after the blooms died. It grew leaves only for at least three or four years before it finally started blooming again. Last year it was the prettiest color of all our hydrangeas. It had two different shades of blue and purple flowers. All my others are pink. Last fall, I began to put all of our used coffee and tea grounds on my pink ones, hoping to turn them blue or purple. If not that, then at least a deeper shade of pink!

I have two hydrangeas plants placed next to each other. One blooms beautiful flowers and the other never blooms. They were planted at the same time and I was wondering why.
