Hi Carl, this is Mike :), who is Rob,
My problem is I have a job throwing out good seedlings. I could end up with more than 50.
Nothing special just the Miracle Grow potting soil for the seedlings and cuttings. I've done some Fuschia cuttings recently and they seem to be doing well in Miracle Grow ($16 for 2 cu ft)
I use the cheaper Supersoil ($8 for 2 cu ft) for mature plants. It tends to be more fiberous although I noticed recently it varies from bag to bag. One bag I had a couple of months ago was almost like sand and would not drain and the latest one has lots of wood fiber in it, but for half the price of Miracle Grow and with the amount I use I have to watch the budget. If I had the time I would probably mix some cinder and orchid wood chips in as well as the Epis like good drainage.
Looking our for the spring specials on potting soil about this time of the year.
Mike
