Yeah. TBH I have yet to see a situation in which “tons of compost, mulch, and other organic material” is not a good answer. In clay/silt, it helps to break things up so they drain better and pack less. In sand, it helps to retain moisture so it doesn’t drain too quickly. And generally it feeds and introduces those ever-important microbes, on top of the usual nutrients. Really can’t go wrong. There was even a master gardener a century or so ago whose entire care regimen was simply to add mulch to about knee-high continuously (IIRC she didn’t even water).
