Hello! I'm looking to work a little harder at my colocasia this year and have decided to start fertilizing them. Does anyone have any recommendations of brands they've used and really like? I've got a diamond head, redemption, waikiki, hawaiian punch, black coral, illustris (in a pot), white lava, pharaoh's mask, and a jumbo green planted outside. I live in zone 6b. Thanks!
