Elephant Ears often grow in swamps where they're almost always submerged in water, so overwatering is unlikely. In fact, when mine do something similar, it's because they're too dry, so they might be getting too little water. Sometimes the outer leaves will just die because, I guess, they're old and as they do, will take on a similar appearance. As well as if they get too cold (I'm guessing that isn't the case with yours). That's all I know. Generally you stick them in wet ground and you can't stop them from growing everywhere. Perhaps it would rather be outside?

My EEs do well all summer, but had a new experience happen with the black taro that is in a pot right beside it. The BT was failing, no matter what I did it would not thrive, tho the ones in the garden pond and in the ground 15 feet away were doing well. I finally decided to just pull the poor dead plants from the pot and let the rest of the plants take over. To my surprise the roots were totally gone! I have wave petunias, allysum and another foliage plant in that planter and they are all fine, only the taro was struggling. Someone had mentioned earwigs eating roots, think it was Paul James on one of his shows. I have seen a lot of earwigs in the crevices of that plant, do you think they are the culprit? Why only that plant?

here is a pic, leaves are about half the size they were a month or two ago. The plant on left used to be tall and luscious, now almost nothing there.

It's my first try overwintering coleus...I will make some clippings from the mother plant and keep the mother on a windowsill in a cool room and in my guestroom. I had to take the metal stairs in before it gets too wet and so I thought I use the room for plants as well. It's going to be one of my adventures :-) normally my succulents and palms overwinter in that room and so I will see if it is ok for others too. I will also put the smaller EEs on that stairs, I read they can be overwintered that way. The big Pink China I will overwinter as a tuber. Next year this will be my sleeping room and the sleeping room will become my plant room. It has a southward faced window and is much bigger than the guestroom. It's wasted space. I only sleep there and so I can put my bed into the guestroom as well :-) The crazy plant lady is making plans again,lol... I still love my hosta but there are so many interesting plants out there...and after that terrible hot summer I had to find something for the sunny spots and so I bought some succulents. I really like those little aeonium trees and I think succulents will be my next favourite hobby together with EEs. EEs and hosta seem to have the same need for partial shade and a lot of water and so I will mix them up more next year and in my mind it already forms a nice picture, hope it will work out in reality. I'm never at a point where I can say my garden is complete...how boring that would be...I don't want to sit outside and only look at what is growing there...I need to have my hands in the dirt, contact with Mother Earth is very important for me...
