soil for good tasting onions?
I grew yellow sweet and red onions last year (sorry, no clue the variety, got sets at the local wally-world). I put them in raised beds amended with potting soil, peat moss, soil condtioner and conpost. My native soil in the back yard is a taupe/grey slimy clay. The onions grew happily, and I harvested in the same vein, but the eating was not fun!! They were both so strong, we ended up using very few, with my husband begging me to serve "store onions". I am willing to build raised beds on the top of my soil from scratch from anything I can find or buy (within economical reason), but can't find a good guide. What would y'all recommend?
