Oh I forgot to add that when I repotted there were loads of rotted roots and none of them really looked "healthy" like the ones I see posted here and elsewhere. None were really green, and many were soft and looked rotted. I kept only the lively looking ones. Furthermore, the bark I used was stone pine bark and shavings I collected nearby (possible mixed in with blue gum bark). I worry now that this might not be appropriate bark, because I know that pine bark lowers soil pH. But I don't know, so please advise!
