Elephant ear bulb not doing anything.
I've had this "mammoth elephant ear" bulb in moist soil for nearly a month. It's not doing anything. It's in a pot, in a sunny location, the soil has been kept moist. I dug it up yesterday, no roots, shoots, nothing, nadda, it's exactly as it was when I planted it. Not squishy either, no rotton smell when I dug it up.
Did I do something wrong? How do I get this thing to grow?
