Store-bought potting mix suggestions?
This past spring I repotted all my aroids in Scotts with something for root growth because the mix I was using before was going dry too fast between waterings. I think it was Schultz.
Well, the Scotts is too.
I need suggestions for store-bought potting mixes that'll keep my syngoniums, monsteras, scindapsus', aglaonemas, anthurium, ZZ & philos happy in the high desert, supposedly alkaline environment.
Would Miracle Gro Moisture Retention be too heavy?
