About ten years ago, when the yew hedge was about two feet high, a small herd of deer came through and munched the hedge in half. I never saw any deer in New Hampshire for my first decade here but I knew about the toll they could take on the garden from my gardening friends in PA and CT. If you want to keep the deer out, they all said, you need to install a deer fence. I also read that they don't like to be trapped in small spaces. So I installed a deer fence around the perimeter of my property except the side of the garden along the street where there is a picket fence. Then, this winter, I noticed these tracks in the Hall with Balls just inside the picket fence doorway.
That very day, I installed deer fence on the final entry portal to the garden in the Hall with Balls. I didn't want a single deer's tentative investigation to turn into a full blown smorgasbord at the Gordon Garden!!
