When is the best time to prune a hydrangea?
So, if you prune in late summer, fall or springtime, you are probably cutting off the bloom buds and you will get no flowers. Environmental conditions can affect blooming (water, light), but, if the plant is established and appears healthy, I suspect pruning. You should prune hydrangeas immediately after flowering. It may be too late now and I wouldn’t. In the spring, check and see if you have new buds formed on the stems.
