I'm getting ready to plant my first Colocasia Big Dipper. It will be planted in a large pot on my porch. I'm wondering if this plant likes any particular kind of potting medium. I have the typical Miracle Grow potting soil, peat moss, and pearlite. I was going to do a mix of about 1/3..1/3..1/3 of the three. How does that sound? Help please.

Thanks!

Linda
