Hello everyone. This coming season I will be growing a large container garden. I want it to be cost effective and get more out of the garden then what I put into. Growing everything from greens to tomatoes, I need a lot of containers which I will pick up at a local nursery for free hopefully. I will be doing some plants in the 5-1-1 but I have to sift out mulch to get the fines. I cant find sifted bark fines anywhere so i just get pine mulch. Here is the big question, can I use the mulch and peatmoss without perlite as a grow medium, provided I take some huge nuggets out and ballance ph with lime? I want a very economical mix that will perform just as well as store bought potting mix. Thanks!
