How can I tell how big my ginkgo tree will get before I plant it. I don’t know which species I have. Can you help me identify it?
The dwarf plants look a bit different from the standard ginkgo and yours looks like the standard gingko, which can get to 80 feet tall.

the tree. Plus I have a competing branch at the top. Is it OK to do some pruning right now I’m planning to sell the house, and I won’t be here in the fall. I also have a similar question about pruning my skyline locust. I’ve also attached a couple of photos of that tree. The locust was planted a year ago.
You can do light pruning now since you are moving, such as removing the competing leader at the top of the Ginkgo. I don't see photos of the locust, but light pruning should not hurt it either.

Hello, I live in Cornville, AZ near the Cottonwood/Sedona area, so it gets quite hot in the summer and can go to 15 in the winter nights. A friend just gave me a 15 year-old potted Gingko Tree, which has been kept outside in a large pot, and is quite straggly and sparse. I placed it under a pine tree where it gets morning sun and filtered light the rest of the day. I'm concerned that being in full sun all day is way to hot for this Gingko. I want to plant it in the ground this fall. Because of where I live, do you have any suggestions as to the best way to plant, water and feed the tree.
You may have a weeping and/or dwarf variety. Gingko trees do best in zones 3-9. Your location is in zone 8b so the tree should be adaptable to the climate, but afternoon dappled shade may help as you suggest. They do prefer moist soil but can withstand occasional drought. Here are care tips for planting your tree in the ground:

I recently transplanted a 6 ft tall ginkgo tree that had been planted in the shade 25 years ago. I wanted to move it to a sunny location in my yard. During the transplant The tap Root broke off. I am hoping it will survive with the remaining part of the tap Root and all of the smaller roots in the root ball. Should I prune the top back to accommodate fewer roots? And if so, how do I do this? I don't know whether to trim the top leader or only the side branches which there are not many. Thank you
The tap root's purpose is to stabilize the tree, so if you got the feeder roots, it may be okay. You would have needed to cut the tap root anyway. This article tells in-depth how to transplant a tree and it doesn't say to trim the branches. You never want to trim the leader. However, it may have helped to root prune a few months before transplanting.
I have these two pups growing at the base of my ginkgo biloba tree. I am wondering if I can cut them dip in root hormone and propagate them. If so, when is the best time to do it?
Suckers always should be removed from a tree. If the tree is grafted, you won't get an identical tree if you grow the shoot. The best way to propagate a ginkgo is though cuttings to be sure you get the same attributes as the parent tree. But you can try growing a sucker shoot, unless the tree is grafted. Fall is the best time. Here is more:

I have 2 seventy five year old gingko trees. Although healthy very tall. Is it safe to prune or top these trees. Both are beautiful but so big.
You wouldn't want to top the trees, that will bring out the ugly water sprouts. It's too late for reduction pruning, too. At this stage, the only real pruning they need is to remove dead or broken branches. If they have become a safety hazard, it is best to remove them. Here is more:
