I've been using either "planting mix" or "potting mix" (mostly the former) mixed 50/50 with fine redwood bark. I highly recommend saucers under the pots during warm/dry weather. No need for added sand/perlite/vermiculite (maybe a different story if you are potting in clay or heavy soil).
Evaluating an iris seedling, hopefully for rebloom
