Can't find bulk compost
I am trying to find some bulk compost to buy in the Tampa area, but have come up short. I need about 3 yards or so, so I didn't want to go buy tons of bags from HD/Lowes. The best I have found so far is a place that has top soil and Potting soil in bulk. The potting soil has a considerable amount of composted horse manure in it.
I was going to use a modified version of Mel's Mix (less peat than he calls for). Any suggestions? I can get some of the topsoil or potting mix, and mix in some bagged compost, vermiculite, and peat, or just use the straight potting soil, as I assume it will have pearlite/vermiculite mixed in, or I could just mix some peat and potting mix/top soil, or FINALLY I could use their top soil in place of compost.
Please help... I'm just not sure what the best approach is. Thanks.
