Pruning Oakleaf Hydrangeas
Oakleaf hydrangeas are pruned for number of reasons, to maintain shape and size, to remove dead or diseased wood and to improve flowering (flower size or flower numbers).
The key to pruning Oakleaf type hydrangeas is to understand that they will flower on old wood. This simply means the growth that they put on the previous summer. You could in fact not prune them at all, however after a few years they may become unruly.
Dwarf types generally need no pruning at all except for the removal of spent flower heads.
The simplest pruning method is to remove some of the older canes right back to the ground every few years. This will help regenerate the plant, try 1/3 of the canes at a time, every 3 years.
As a rule, selective pruning in spring will produce larger flowers, fall pruning smaller flowers, but more of them.
You can also lightly prune immediately after flowering, simply prune back 1/3 to 1/2 of the new seasons growth. If you prune back harder you will get no or very few flowers the next season.
