So my calathea's, specifically rufiabarba has gotten quite large. It's not quite at the point where it needs to be repotted but it's not far off.
The problem is I've read heaps of recommendations for the soil needed for these and I'm not sure which one to go with.
The most frequent mentions are African violet potting mix and a home blend of potting mix, peat and perlite.
Can anyone help me out from your own experience?
