A large branch of our mature pear tree is rubbing against our vinyl fence, and will soon break through. I am considering digging under the tree to slightly change the angle so the branch will clear the tree. My wife wants to remove the branch but I would prefer not to. The branch is about 5 inches in diameter and at about a 15 degree angle to the trunk. Is my idea to dig under the tree with a hose and pull it into a different angle slightly a dumb one?
Digging up your tree or attempting to loosen the tree could result in the death of the tree.
It would be best to prune the tree or move the fence.

It may be that it has been very wet, which will lead to a fungal or bacterial infections. This appears to be an infection starting in. My preferred remedy is as follows: First, you will want to prime the ground with dolomitic lime, then spread wettable sulfur to Kill off any infection in the soil. I Also like to spray the plant itself. Mix a few drops of one or more of these ingredients into warm water with a spoonful of coconut oil: Rosemary oil, lavender oil, neem oil, garlic oil, cinnamon extract/oil and for really bad cases, also add clove oil.

Pear trees. Need to get rid of a bug that causes Crystal to form on limbs white and Amber in color. Help.
This sounds like canker disease. This has no cure, unfortunately. The best method is prevention. This can occur from many reasons, but the idea is that there is an injury which introduces the disease to it. The only remedy would be to cut any affected branches, and make sure to clean the counds with peroxide, or any other antiseptic.
