Spiders, huh? I didn't have any of those either. Now where I live now, I could really use a bushel of those things, even though this is new construction, or maybe because it's new construction, I don't know.Knobbyoaks, I'd always heard they repelled spiders. The wood from those trees is some of the hardest around and many a fencepost was made from them in early settling of the country, I understand. Horse apples are extremely dense, hard and heavy. We had one in the yard where I grew up.
