S.S.
I had an elderly neighbor years ago who gave me this advise about africian violets, first "old maid don't have babies" meaning don't use the outside older leaves for sprouting new plants. Second was "They don't like to go to bed with wet feet" meaning don't water them at night. She had a lot of violets, so it must have worked. Mine do well with north windows, light but not direct light, and I remember my neighbors word almost every time I water them.
