The edges of my elephant ears are turning a yellowish brown then black. They did the same thing last year. I have them planted in a large pot. Last week I cut them back to the bulb and replanted. What am I doing wrong?
This could be as simple as a watering issue. To much or to little. Make sure the pot is well draining. You don't want the roots and bulb sitting in soggy soil. This will cause root rot.
