Hey yall! I purchased my first elephant ear plant, its not hardy in my zone but I planned out putting it in a planter so it can sit outside in the summer months then come in during the winter. My issue is the edges of the leaves are becoming brown and flaking off. I've followed the label so far, keep moist and it sits in a spot on my covered porch where it can get indirect sunlight. Any tips on what I can do better?
