I get 4-6 large bails each spring. I try to find the large bails but sometimes I have to settle for more smaller cu ft sizes. I have an old fur shed that I store them in for the summer months.
I slit open across the top of the plastic bags and push a rebar down into the the bails a foot of more to break up the compacted peat. I get most of it dry by summers end from evaporation.
Then I sift it all and spread it over a large tarp over our shop hardtop and rake it frequently until bone dry. Shovel it up and store it in clean barrels, drums , old clean feed sacs,or some large burlap bags I bought for that purpose.
I hang them from the beams of another barn until needed. I store all my grass clippings the same way in empty feed bags or large burlap bags. I have bags stored all over my place so I have enough air/out dry time and weather protection. I have a few dozen bags stored in my firewood building.
