OK ,the list you posted I was looking for trees here in southern okla. and found the black walnut and hickory on it and red oak was there n at the bottom if I didn't read it wrong.
No, I really don't. One member who read your post pust a place to click on about trees to tap and red oak was one on the list. I'll have to do some reading on the subject before I try tapping any. The trees here are all leafing out now.
