Why Doesn’t My Hydrangea Bloom?

By May 22, 2010

Follow me on:

There are certain questions that bind us together as gardeners and "Why doesn't my hydrangea bloom?" is in the top 5. Generally when hydrangea fail to bloom it either has something to do with when the plant was pruned or whether the type of hydrangea is suited to your area. Luckily there a more and more new hydrangeas being introduced that almost continually set flowers, no matter what. But if you have an old-fashioned hydrangea in your yard that's causing you frustration, don't give up. The first thing to do is to identify what type of hydrangea it is. Then check to see when, or if, you should be pruning it. Hopefully you'll be seeing flowers again within a couple of years.

In my area, deer love annabelle hydrangea and the macrophylla. If they don’t bloom, you might check for deer browsing in other areas of your yard. Same with roses. Deer are moving in toward the cities.

Of course, if we could get the deer to munch at the right time, we’d still get blooms and we wouldn’t have to prune at all. I just don’t understand why they don’t work with us. There’s plenty to go around. ;-)

Could be 2 reasons. One… not enough phosphate or phosphorus in your soil. Two.. possibly not enough pollinators in your area.
