I know this has been discussed somewhat before but just had to post my excitement. I dug up a 6" tall tree growing from an acorn when I was a kid at my aunts house, brought it to my parents and we planted it on their farm. 15 years later "fall of 2013" they were building a new house and the tree had to be removed so I had it moved to my house down the road. It had been producing acorns a couple years at that point. I kept a few acorns back and in early 2014 I planted them in rootmaker 18s and in late may that spring I put them in tubes at my house. This spring, I discovered small acorns on one of the tubed trees. Basically 5years in the ground from seed and I have acorns on it They are either bur or schuettes oak trees, never have decided but I was happy to see it! Especially considering how bad the weather has been here the last few years and the tree is only a 7.5ft whip basically.
