I have an Oak tree that has several holes at the top where the main trunk gets divided to 4 and 5 branches. How can I prevent the damage to the tree? Please advise.
Keep in mind the holes probably won't cause the tree to die, and filling them may actually cause more harm than good. This article will help you determine whether or not to fill them, and how: https://www.gardeningknowhow.com/ornamental/trees/tgen/patching-tree-hole.htm
I have a tiny (few inches tall) oak sapling that sprouted from acorn in March. It got burnt in the sun, and the leaves are brown but with a little green still left on them. Can it be saved and, if so, HOW? Many thanks... Sdx
It will just depend on the severity of the leaf damage.
Wait and see if new leaves continue to sprout.
Here is an article that may help.

My young oak tree has some bark damage caused by rabbits. About 2/3 of the circumference by 10 cm high. The trunk is about 7cm deter. Will the size of the damage stay the same size, or will the damage grow in proportion to the size of the tree? It looks a big wound now, but in 20 years would it be tiny??
Allow the air to circulate around the wound but make sure to watch for insects or disease.
The wound should heal and it will not increase in size as the tree grows.

We have several small burr oak trees growing in flower beds. Should I put them in pots or transplant them elsewhere? My husband wants them to grow in our yard.
Unless the trees are in a part of the yard that you want to grow a large tree, it would be best to remove them or you can certainly try transplanting.
This link has great information on this task.

Can I top and how to trim a "Castle Green Oak" tree?
It looks like this is a relatively new columnar oak variety. Here is more information about these trees:

Letting the tree grow in its natural shape is the best option, and topping is to be avoided. But, here is an alternative approach recommended by a university extension agent for someone who had a similar question:
I'm looking for a shade tree to provide some respite from the sun for our front porch. Can you tell me how much yard space (radius) a Southern Red Oak needs and how far from our house we should plant? We have a small yard so I want to make sure a Southern Red Oak will fit before purchasing. Thank you!
Southern Red Oak is a relatively large and fast-growing tree. It has a canopy spread of 60-70 feet and a height of about 70-80 feet at maturity. It should be planted at least 20 feet from the house.
