Question on Yews?
I had about 14 overgrown Yews that I pruned heavily around mid-March. I cut them back from around 5FT to about 2FT. Most of them are showing some growth, but about 4 of them haven't had any buds or signs of life. How much time does it take for them to generate growth? Is it possible they died from the heavy pruning? Any suggestions on how I can verify this? Thank you.
