There is a big tree in front of the doors and windows. Does it affect feng shui?

First, the big tree is not in front of the gate, so there will be no big problem. Please rest assured.

Second, the tree is in front of the window, but it is flourishing. As long as you don't block all the sunshine and make your home feel dark, there will be no problem. If it continues to grow and makes you feel dark at home during the day, you can ask the other party to cut off some branches that extend to your home.
