When do you prune oak-leaf hydrangeas?

Oakleaf hydrangea blooms on new season growth. This means that you want to prune it before the growth begins. That would mean to prune in late winter or early spring. You would want to look at the branches and see if some of it is damaged by the winter. If it has, then prune off all the damaged bits. You want to end of the branch that is left to be ready to leaf out when it warms up.





These bushes are mainly grown for their leaves, so if you prune a bit late and cut off the new growth that would have produced flowers, it isn't such a problem.

IN THE FALL IS THE BEST TIME, IT WONT DELAY NEW GROWTH OR BLOOMS
Reply:Remove growth by 1/3 to 1/2 cutting back when new buds are just appearing. Give a good dose of your preferred fertilizer by adding around the plant. This will give them a good start for the new seasons growth. They are reasonably forgiving plants so don't stress too much.
