@guidedbywire Yep. Sphagnum seems both "easy" yet tricky (I just started with it this year). Like- it can take things (absorb minerals, tannins, etc.) up to a point and still look healthy for a while, and then suddenly collapse, turn black and die at the growth points. That is interesting about dormancy and I'm curious too if it helps with the type I have (outdoor grown controlled cultivation from central Europe according to the seller).
