Hello, I have 3 questions: 1)What should be done with trees that were just paved next to? Is there any care that should be taken? 2) what is a general rule of thumb for water needs of a mature tree, I realize all trees and situations are different but I am just looking for a general rule of thumb. Through some research these are the 2 things I read. - One to three inches of water a week - 10 gallons per inch diameter of trunk a week 3) I was asked this question and I have no idea; What can be noticed when a pine and oak are planted next to each other, I believe the question was asking in terms of figuring out what type of problems/diseases one may get and the other will not Thank you for reading and any help you can give.
