acce, You didn't inquire about this, but your tree looks to me to be in a questionable location. From the shadows, floor litter, and trees in the background, it looks to be in a shady area. If that's the case you're fighting an uphill battle. Not only will the shade make things more difficult, but the competition from roots of other forest trees will add to the stress on your tree. Peach trees aren't like Oak or Maple trees that can be planted pretty much anywhere and grow without care. Instead for peach trees to thrive, they must be planted in a sunny location with good drainage, and little root competition. At least that's my experience.

Is the "hump" perhaps due to some subfloor issues? If you have a basement,and the ceiling on it isn't finished, check to see if the floor frame below may be the cause. I had a similar issue, but the floor had delveloped a bit of a "dip". The heating duct ran between the framing and because of that, the stabilization strapping (usually seen as "X's" between the 2 X 10's was missing where the ducting was. That caused the flooring to "give" a bit in that exact area in the upstairs room. Your issue may (or may not) be related. Doesn't hurt to check it.

I don't see "minor cracks" so can't offer any advice on that. Do you mean "fix" with other plants? If so, the only room you have is for small plants .... annuals, groundcover, low perennials, etc. Or maybe you mean "fix" by filling in the planting bed with pavement ...? Sometimes, when you have a very skinny strip of landscape space, it may be better to eliminate it. We can't see how this space fits into the larger scene so it'd be hard to advise on that.

I just had my floors installed. The floor looks nice except it dips and moves in some areas. High traffic areas! I researched for two years on the proper install for this type of flooring. My sub floor which is concrete was very uneven, especially in the high traffic area. I discussed with the hub and watched countless videos on the proper install: level the floor first! We hired a guy who insisted that an underlayment under the flooring will fix the problem. I disagreed d/t my research but my hub thought “good idea”. We will save time this way. Again I disagreed but didn’t win the argument. Now the floor is down and there are very noticeable dips when I walk in certain areas. The installer suggested that we only wear soft sole shoes or socks in the area (high traffic area!!!!). As if it’ll prevent the floor from eventually pulling apart or breaking. He does not feel he should get paid for the job and neither do I but he did put in a lot of hours. What is the best way to fix the areas that are messed up?
