I had a large, beautiful holly tree on the corner of my house. Today I had an arborist come to do some trimming for several trees on my property. We asked for the holly to be taken back some and this is how it turned out. This is not at all what we intended as we loved the Christmas tree shape! Is there any way to encourage the lower branches to grow back? Will some grow back on their own? Or are we stuck with this shape forever?
