This year I experimented with a few growing mediums. Some I used just because I had an overabundance and wanted to see how they performed.
I tried
1) Orchid mix & Miracle Grow potting soil
2) Miracle Grow potting soil alone
3) Cactus Mix & Miracle Grow potting soil
4) Cactus Mix alone.
I think #1 has produced the best results.
What have you tried?
