Container planting spacing of Elephant Ears
This past spring I bought two elephant ear (Colocasia) corms and inadvertently planted them together in a container in my garden. They did well this season and I am hoping to see them grow for many years to come. Do I need to do anything about the lack of space between the corms? Should I dig one up and move it to the other side of the container or another container? If so, when? Now or late winter? Or should I leave well enough alone since they both semed to do well this season and just leave them planted where they are? Thanks.
You could separate the bulbs when they go dormant.
