I'm not sure, but I think you need some amendments to the straight compost,
which might compact and get soggy unless you water lightly. Some kind of
inert filler like peat or coco fiber, and some kind of aerating thing like perlite.
Most good mixes have more filler than compost. Here's Big Cedar's recipe:
Thanks for the replies. I live close to a mushroom farm they sell ten cubic yards for $20 so I decided to try planting directly in mushroom compost didn't do so well the compost compacted. The plants where stunted with a woody base the leaves turned lime green except for the veins on the leaf They stayed green. I threw some fertilizer on the plants and they turned green again started to grow and flower. I'm just trying to figure out a way to use this stuff to make the plants thrive. It cheaper then soil cost!
my mother has her raised beds filled with pure compost and does well with most veggies like tomatoes and cukes, but her peppers dont seem to thrive like the others small/few pods. might be too much N or a ph issue. i put 6-8" ontop of my garden in the fall and till in the spring. i'm guessin you access to plenty of sand, might try mixing at different ratios and see how it works.
