Hello, I am going to be trying a Quartz mountain live oak. I will be receiving the tree within the next 5-10 days. This is the quartz mountain live oak, which is listed as zone 4-8. It is more likely zone 6 -9. I have faith in it as THE MOST HARDY of LIVE OAKS in the USA. But, when the growing months, of this summer are over, which are many months from now. I will, quite frankly need to protect this tree over it's first winter here in zone 6 Pa. If I could get some burlap and put the burlap around a protective fence, will that be okay? I don't want to put a solid barrier over it, (like a plastic garbage can,) cause it would not allow air to the tree, and one night may be cold, and the next day may be breezy and just mildly cool, and the tree would need some cool air to prevent rot or fungus. Should I get some burlap to wrap around a fence, so it doesn't touch the tree leaves, but, the wind can still prevent rot? This situation is several months off. But, I will need to protect this oak tree eventually, a full hardiness zone colder than it is used to. Most of the Live oaks I have tried have done fine in the fact that they come up from the roots. I just need to have my current Live oak, Quartz mountain Live oak be hardy enough to retain it's top growth for several years. So, this winter, winter 2015-2016 I will likely need to protect the Quartz mountain Live oak, in my yard so that it can continue to be a source of shade and a healthy tree in my yard in Pa. I think that wrapping the Q.M. L.O. in Burlap around a wire fence will help.
