Collected Quercus virginiana

Growing well in the bed. Wabbit threat not yet eliminated but will be soon.

So now I have 5 live oaks that hold a lot of promises. This is super exciting.
 
Incredible growth by my collected live oaks.
Collected a short while ago, this one has shoots that are 1/2” in diameter.

This one's only $20 K pick up in La. only

$20K huh. Well then my 5 live oaks are my Roth IRA.
 
Here comes the big question for me.
Can I keep live oaks in zone 7? Normal range for live oak is 8-11. I am doing it banking on the idea of somehow giving them some winter protection to keep them alive.
Never mind. I was lazy and didn't search as I should have.

Not sure about zone 7, but I tried and failed in Wisconsin. Tropicals were good inside. Hardy trees good outside. Broad leaf evergreens that were out of their comfort zone - no good. I didn't have the space for a second, "not quite tropical" grow tent or greenhouse.

I'd say it depends. I have quercus fusiformis--the upland, inland, tougher cousin of the Southern Live Oak--quercus viginiana--here in Zone 7. If you're at elevation away from the coast, the more protection you will need. The closer to the coastal plain you are the better the species will do. It is native up into the Tidewater of Virginia, although it doesn't grow with any of the stature it gets in along the Gulf Coast. Up here it is mostly a shrub, but there are larger, older trees around.

Bottom line, you will likely need substantial winter protection for them--not just mulch in the backyard or a cold frame. Early cold in November (like below 24) can mean disaster as they're generally still active. We've been getting very deep, very cold, prolonged cold snaps more and more in mid-November these days. While a night in the low 20s followed by a day in the 50's probably isn't going to do much. But a string of nights in the mid-20's followed by a string of days that don't make it out of the 40's can mean roots and soil can be frozen through. That doesn't discount the deep cold of Jan.-Feb. I had a small fusiformis (about two inches of trunk, chopped to about 8 inches tall) for a while. The tree would push vigorous new buds in the spring, even get two foot extension growth that I wired into initial branching. Then come winter I mulched it into the garden bed. Come January, the cold would kill off the branching. The following spring the tree pushed new growth from the trunk. That went on for three or four years, until the trunk died as well.

So, yhey may likely withstand some winters where you're going, but over time, they will likely decline or simply be very sluggish in growth. That's what mine did before I started storing it in a cold greenhouse for the winter. I believe that if I hadn't begun doing that, the tree would be long gone (and remember, fusiformis is more cold hardy than virginiana).
 

I also planted one in my parents' front yard, which has survived three winters there in Cecil County, Maryland.
I've seen articles like this before. I don't put too much stock in them--until I see a live oak in Pa. in the ground that's older than 20. There's landscape live oak on the grounds of the National Arboretum-both Virginiana and Fusiformis. Been there for years, but they struggle. The trees in the link were planted at the Arb. in the 1980s, making them 40+ years old. They're awfully small for 40.

The evidence is what it is. That is to say, there's not much evidence live oaks can live in zone seven, but there is a little bit of weak evidence, and that's worth sharing, if only because it's interesting.

Aight!
Even if Ser Clegane manages to live after being beheaded and delimbed, he may not survive Winterfell. Duly noted.

That's what I'm getting at clumsily, unfortunately. I'm of a mind that my live oak could probably get by in-ground here in Zone 7 in an optimal full sun site that is sheltered from the North wind.

In a container, it probably would fade and die after six or seven winters--less if there's early deep freezes and the tree is still active. Keeping live oak above the Mason Dixon can be done, but it depends on what you're willing to invest to do it. FWIW, my live oak is one of the most responsive bonsai subjects I have. It's tough as nails other than the winter sensitivity (and it does snow in its native range). It can take full summer sun all day. It backbuds reliably and vigorously for the most part when hard pruned. It pushes roots like mad (it outgrew its original container) and no real pest issues (other than gall wasps in the summer which are easily removed).

If you want to provide substantial shelter for the trees you have, your live oaks will probably behave similarly. It boils down to what you're willing to put up with.
