Container gardening soil question [View all]

I've read so much and watched so many videos that I find I'm back at step 1 in trying to decide about potting soil.

I think next year I'll deal with larger volumes and making it myself. But, for now, I'd really appreciate advice regarding a fairly inexpensive bagged potting soil that can be made much better by adding perlite and vermiculite, for example.

I have a real issue with drainage and Miracle Gro hasn't worked out well for me in containers.

I'm not looking for the perfect bagged soil but rather suggestions on fairly inexpensive and available potting soil (organic) that I can amend.

Thanks!
