property ends at the sidewall

Hi. Sorry for posting so many questions. This is my first house.

So my house is the last rowhouse on the block and its sidewall is exposed to the rear side of the backyards of the houses around the corner. So our property ends at the sidewall and the neibours backyards starts at that very point. As you can see from the picture two neighbors built boxes for the plants right on the my sidewall. Instead of the original design with grade sloping away from the house. I assume they will dump water into the box and this water will go right into my basement. I suspect there was no hydro isolation put between their soil and my wall.
What would be my options in this situation?

Should I leave it as it is (since it was like this for many years and the house did not fail yet)? Should I ask them nicely to disturb their soil and put the watertight membrane again the wall? Any other way to deal with this?

Also you can see on the picture there is a massive tree grows ~4′ away from the wall. I afraid that its roots will damage the foundation. Should I convince myself, that this tree was there longer then I was alive and go around my business. Or should I freak that the tree’s roots will push the foundation and house will crash?

Or maybe the best way to deal with this is to call a foundation specialist or a structural engineer for inspection. Can you recommend somebody in this field? Of course I need an objective concussions, not a sales pitch for the expensive repair work.
thanks.
