they can be in indirect light.
the one i've got a problem with is normally in a north facing window - was fine for almost 5 years in that spot. since it started having a problem i've brought it down to the kitchen where the other one is - and i put it in a different container as the one it was in had some algea growing
in it...i don't know why the algae started growing
-- AHH HA! just had a thought...i know why there's algae in the other container!!! a tree
across the street fell down in a storm during the summer...guess that window gets more light than it used to!
ahh, nice to have the mystery solved! i hope that stalk survives!!
anyhoo, if you've got the plant
in water only, then you should never let it get bone dry...that will cause the leaves to yellow up from lack of water.
