Pruning old wood versus new wood?
When do I prune? What is old wood versus new wood?
Oakleaf Hydrangea
In my description of many flowering shrubs and trees, I refer to the correct time to prune as to whether the blooms come from old wood or new wood. Knowing the correct time to prune is is important so you don’t interrupt the plants bloom cycle. Knowing if your plants bloom on old wood or new wood will determine the best time to prune in order to promote healthy growth and “flower power”. This often depends upon the bloom time and the species.
