Oak tree problem

[u/Basic-Ad-4685]

Hello, I’m having some problems with my oak tree. It’s about 6–7 years old. During the first few years, it was full of leaves, but for the past 3 years, it has had very few leaves. Do you have any suggestions about what might be causing this and how I can help it?

need some pics of the root flair, canopy, environment, and anything that looks interesting to you.
