I've got to go look at mine Rocks, maybe there is something hanging. They are over an inch in diameter, but only 3rd or 4th leaf. Post some pics of them if you have them, I'd love to see 'em!I've had some burrs start putting out small amounts of acorns after 6 years or so. Trees aren't hardly an inch in diameter. Not even sure if hybrids but just some ones from a local chapter of NWTF. Posted some pics of 'em on a forestry forum a few years back and they thought looked mostly like a regular ole burr oak and not hybrids (but had good roots and looked to be in great shape when planted as a bareroot).
