Hey all-

After a couple years in, my perennial callas are finally setting some "baby tubers". My question is- how long should I wait before harvesting them and potting them up? Until the sleeve browns up? When the fruit browns up?

One of the neighbors (not one of my regular gardening mentors), suggested fertilizing them in fall, which I am hesitant to do without some endorsements from you guys. Thanks in advance! lemonbird
