Lack of doublefile viburnum flowers this year.
I have a large patch of doublefile viburnum bushes. They are 8 years or so old. Every year they produce a spectacular display of flowers, except this year. This year there are a lot of single flowers, but nothing close to what is normally produced. I noticed earlier this spring excessive squirrel activity in the viburnums where normally there is none. Can squirrels shut down flower production of viburnums? What to do about it?

Reasons for no or few blooms are improper pruning, too much shade, winter kill of buds, and squirrel activity. Squirrels are known to eat tender flower buds as well as clip the flower heads. This activity is difficult to control as it can be normal squirrel activity.
