Japanese holly renewal pruning?
I am clearing all the junk out of my long hedges--finally. Hacking away at the japanese honeysuckle and bittersweet vines that are such pests in my yard, I pulled all the growth off a large Japanese holly. It looks "tonsorial" as in the top is totally denuded of leaves from being shaded and there are only leaves where it wasn't covered. Plus, I discovered a monster of a hole (maybe woodchuck) hidden directly beneath it.
I am going to be drastically pruning the overgrown forsythia next to it, thinning it out and removing the same pestiferous honeysuckle. What can I do for this holly? I'm going to have to get access to the area beneath it to fill up that hole and I'd like to see leaves re-cover the nude areas.
