Pruning Overgrown Yew
I have a pair of old yews flanking my porch that have gotten too wide and my spouse is threatening them. I'm afraid if I try to make them thinner they will get bare spots. (And if I don't make them thinner their lives will be in danger!) Will yew leaf out from leafless inner areas if they're exposed or will I end up with ugly bare spots? Is there a good time to cut?
Can anyone educate me on how these things grow? I believe it's _T. cuspidata_ but I'm not sure. It grows more up than out...the desired shape of these plants is a naturalish blob, not a sheared gumdrop, but most of the green on them is on the outside. I suspect they'd be a good topiary variety.
Any tips would be appreciated. Thanks!
