It's not my intention to "scare" anyone, but, my on going rot problems were all "soil related", so it's wise to "proceed with caution" as far as amendments go ! I believe, considering my experiences over the last three years ( and considering that I made those beds with a "trucked in, highly organic soil mix) that I would, if I were you...and had any doubts about the quality of my soil, or the need for any amendments.... contact my local County Extension Agent....they will help you get soil sent off for testing....it's not expensive, at all(at least here, two samples were sent @ $18 per)....then, you will know WHAT the soil needs as far as fertilizers, lime, humus...everything ! No 'guessing' needed !
There are "home tests" that you can do (info can be found by computer search), for nutrients, ph, and organic content.....but , having it done by "experts"is probably best for beginners. IMHO
