Container mix for blueberries
Mixing up a bunch of 5-1-1 mix for various potted plants that don't fit in my in-ground beds. After reading through the big thread on 5-1-1 it seems that the only switch for blueberries would be to swap the garden lime for gypsum... problem is, I haven't been able to find gypsum locally.
Then I started thinking about what the guy from the blueberry farm told me about planting media and how different it is from 5-1-1. When I bought my first blueberry plants a few years ago, I recall him saying to use a mix of playground sand and sphagnum peat moss and I think that was it.
So, what's a good container soil for blueberries? At this point, I just need to get these new plants potted and don't have much time/money to go out and search for new stuff... I mean, if I have to I will, but I'd rather not. I have available, pine bark much (pretty fine, I can sift it), sphagnum peat moss, perlite, mushroom compost, topsoil, Dynamite 15-5-9 CRF, and garden lime.
