In late summer when the hydrangea blooms have begun to fade and dry, comes a perfect time to do a little shaping of your macrophyllas that can also pay you back double for your work in blossoms. A simple and delicate hydrangea pruning for double blooms is one way to encourage more flowers from what otherwise would have been a single blossom during next year’s growing season.
This year’s blooms were nothing short of spectacular. This mature Endless Summer macrophylla that greets folks along their way to my front door. I pruned this bush last year, the way I am going to show you below with the above results.
Now late summer, as you can see the same hydrangea is looking a bit tired.
The blossoms are beginning to fade and dry. This is all normal for hydrangeas. They make beautiful wreaths. I’ve got a tutorial here. Do you see the stems that are sticking up above the general shape of the hydrangea bush? There are about eight in the above photo from this angle. They simple jut out above the top of the natural shape of the hydrangea. These are the ones that you are going to prune, but the trick is, to know exactly where to prune.
Keep in mind that you are only going to make a single cut on the branch that extends out above the natural shape of the bush. Also keep in mind that this is for macrophylla pruning. The firsts step is to locate just at the edge of the natural shape of the hydrangea, the two healthy “nodes” called leaf buds. Do you see them below my pruners?
Here are the two healthy leaf buds that are located on the branch at the edge of the natural shape. This is where you will make your cut. Like so.
Come next growing season, each one of these buds will produce a new branch each with a bloom from what was initially going to be a single branch and single bloom. You don’t want to go crazy, but simply just prune the branches that are jutting out above the natural shape. Here you can see that I did just that below. The hydrangea has regained its shape.
Typically, this type of late summer pruning for double hydrangea blooms should be done after your hydrangea shrub has finished blooming for the current year’s growing season.
