When is the best time to prune hydrengas?
A. When you prune hydrangeas, it depends on the varietal that you purchase. If we’re talking about the big ball type or macrophylla type, then you should wait till most of the leaves leaf out and prune away all the dead wood. Some bloom on last years growth while others bloom on this year’s or new growth. If you prune back now you will be cutting off your flowers for this year.
