Hi Valencia, I think I'm having same problems here too with many plants LOL. Was tempted to take some outside yesterday with 80 F temps, but today it's 40F!!
I would either keep it in a darker area & on dry side (no ferts)., or just let it grow as it is in the pot & when temps are right, plant outside.
I forgt that Callas have to be dug up in fall. I usually just planted them out in spring before they started growing, but aren't we anxious to see our flowers?!!!!
