I have an oak branch growing on a cotoneaster stand tree. Would this damage the tree?
How do you grow an oak tree from seed?
Find a batch of acorns.
To test if they are any good, put them in a glass of water.
If they float, they will not grow.
If they sink, they are viable.
Peirce a small hole in the end of a tin can large enough for a sapling's stem, but not large enough for a squirrel to grab the nut.
During autumn, select an area where there isn't much competition, and that's slightly shaded then dig a hole and plant the acorn.
Fill the hole with the dirt you've taken out, and sink the tin can into the ground over the covered hole to protect it.
Let the nut stratify over winter, and let the tree grow naturally.
If deer and rabbits are a threat you may also protect the young sapling with a wire fence.
The metal from can will rust and decompose over time while the roots grow down and out the open base.

I recently received information from our lawn care company that our trees had various "infestations. " He made it sound critical, but everything I have read indicates the issues are purely cosmetic. We live in a suburban area surrounded by lots of trees. We have been here for 25 years and most of our trees are very well established. What he said is our oaks are infested with mites and leaf hoppers (there are about 8 trees that exceed 40 feet), lilac is infected with powdery mildew, and the maple is infected with leaf spot and weevils. If he means the Japanese Maple, it is looking better this year than any previous year and it is still less than 4 ft high. If he means the sugar maple - well that tree is gargantuan and there is no way the whole tree can be treated; it is simply too tall. He said nothing about our boxwoods, burning bushes, forsythia, or barberry bushes. I can't help but think this guy is out for a good buck. Would you agree? Is there anything we could do without using a treatment company that would be effective? I remember my mother using soapy water on some plants to treat pests. . . would that work?
Both insecticidal soap sprays and Neem oil work well on a host of insect pests. Since Neem oil also doubles as a fungicide, this would also help treat the powdery mildew and leaf spots.
My oak tree has what my mom calls galls on the branches. They are big knots that grow on them.

Believe it or not we found that hanging a bird feeder in the tree did help stop the problem, along with hanging a wasp trap in the tree in another location as well.
Can a tree's growth of acorns be stopped in some way? I shoveled bags upon bags of acorns in the fall, and now I am digging the acorns I missed out of my yard. It is so much work but my trees are very mature and healthy.
No, unfortunately not. You cannot stop Mother Nature from doing what it's meant to do. While I realize it is tedious (I have oaks in my own yard), this is what these trees are supposed to do - it's their purpose. The older they get, the more you will see. However, squirrels and many birds love acorns, so they should be helpful in getting some of them up for you too.
I have a young oak tree that is still alive even though the bark has been eaten off it by field mice/gophers. How can I keep the creatures from eating the bark off this tree and killing it? I've seen trees painted with something white in orchards. Is this a way to keep the creatures from eating the bark off the tree? If so, is this just plain white paint, and can I use it to save this oak tree?
Do you know for certain that these are in fact the pests attacking the bark? How high up is the damage? Most likely your culprit is due to rabbits. Rabbits feed on and damage the bark and twigs of landscape plants. Their chewing can permanently disfigure or even kill a tree. As long as the tree is thriving, it should be fine. However, removing or reducing the vegetative cover around your tree will help deter these pests, and placing plastic or metal cylinders around the base of the trees (bury them a few inches below soil) should help alleviate any future damage.
