I planted 2 elephant ear bulbs in containers, and I'm wondering if I should repot them. Last year none of the elephant ears that I planted sprouted so that's why I started in containers this year. They are the ordinary green elephant ears. Is there a "standard size" container for one elephant ear bulb/plant? I'm zone 4/5 so I would have to dig them up in the fall and would rather keep them in containers if possible.
Other than planting annuals, I'm new to container gardening.
