Old Snowball Viburnum
I have 2 large scraggly looking snowball bushes due to viburnum beattle infestations. This year we have no beatles but the plants have few leaves and flowers. I feel like I would like to cut them back to the ground for rejuvenation. The flowers are fading now but the plants are looking pretty bald. Is it too late to do a severe pruning. I don't care if they flower next year I just want them to get nice new green shoots. They are 10 to 12 ft tall. Any advice will be appreciated. thanks.
