Repot, repot, repot!
It's only been recently (the past few days) that I've realized how horrible my poor orchid's root systems were! I never bothered repotting them after I bought them at Lowes, etc., and had to cut away tons of rotted roots from all the ones I've done so far. All of them had some healthy roots, too, mostly little ones growing out near the top of the pot where I assume it dries out quickest.
Darn you sphaghum moss!!!
As an aside, I wonder if some sphaghum somewhere around the orchids could help keep the humidity up? My little orchid terrarium's a far cry from ready and I want my little guys to thrive in the meantime.
Everybody's trimmed, repotted, and should be happier, now. We'll just see!
