Q.Do Elaphant Ears Need Lots Of Sun Tom Start Sprouting?
So this is my very first go-around with colocasia esculenta AKA Mammoth elephant ears. I have planted and successfully grown caladiums and coleus. I planted my tuber about a month ago and at the same time I also planted my caladiums. Within a week and half I started seeing my little spout “horns” and another week they opened (untwisted)to form beautiful green and red colorful foliage. I planted them on the south side of my porch because it is mostly shaded and a few feet away I planted my ears. The caladiums I planted surrounding my ears have not sprouted yet either. That specific spot has even more shade than the spot about two feet away from the spot that is producing. Could it just be lagging behind due to less light or will they not thrive at al? I read to plant them in a well shaded area because too much sun can scorch their leaves. The soil is well draining yet stays moist and I lightly mulched after planting all my tubers.

You did the right thing by planting is a shadier spot, but the heat may be getting to them. They won't appreciate the harsh heat without some humidity. They may peak out at the next cool snap, but will likely stay dormant until the weather is more cooperative.
