Please Save my Elephant Ear!!!!
I have a nice elephant ear pictured below that a friend gave me about 8 months ago, planted as is with the bulb exposed. It has thrived and become one of my favorite plants, I know it needs to be repotted, but since I never got around to it I was going to wait till spring.
All of a sudden, yesterday, I touched it and to my dismay found that part of the exposed bulb had essentially disappeared under the papery shell - it felt hollow! Thankfully the majority of the plant is still hard as a rock, and producing tons and new leaves and seems happy, but I don't know what's going on? Is it rotting, is the concavity going to spread? Do I need to cut that part out? I haven't broken through the "shell" to see what is inside (should I?) but I stuck a pen through a small hole, it is like 2/3 and inch deep, and about all the way up (from about 1/2 inch above the soil line) on one side, but not a full half, of the bulb. I assumed rot would have started at the soil, but it actually seems firm right at the soil line?
It had a battle with mealy bug before, but I thought I had it under control. Can anyone help me rescue this beloved plant? (Should I cut away the hollow part and sterilize? if so, how?) Should I leave it alone cause it otherwise looks happy? Please help! (Picture taken just 5mins ago - sorry for the size, I can't seem to get it to reformat)
