Sometimes the trouble planing or scraping around knots and rising grain is that the fibers coming out of the wood in wild grain aren’t well consolidated and resembles the end of a broom on microscopic scale. You won’t get good results regardless the work method if the fibers move around.
I have sometimes been able to get good results by flooding the area around wild wood with thin CA glue or even shellac before planing.
It doesn’t seem to affect staining the wood, as fresh fibers are exposed during scraping or planing.
The first time I did this was years ago on my workbench, when in desperation I used I part West Sytem epoxy thinned with 2 parts acetone.
I’ve never had an issue again with the area despite several rescrapings of the top.
