Dumb Cane Care My dumb cane has recently been turning a little yellow. i watered him last on 6/2 so i watered him again this morning. i want to make sure that the yellowing is due to underwatering opposed to overwatering. he gets light throughout the day, id assume where he is on the window sill is in light for at least 6-8 hours a day.
