I need two trees to go on both sides (two total) of my mobile home. One is to mainly provide shade for the bedroom window because the sun hits it hard all day long and heats it up big time. We live in Bakersfield, CA. It's like an oven sometimes. Here are some pictures of where they will be planted.

Some questions that came to mind were: will the roots extend under our neighbors concrete and end up cracking it in the future? Or even our concrete? Is it too close to our house? How long will it take to actually provide shade?

Thank you for your time. :) -Cody
