I purchased caladiums and while planting them a small bulb broke off. It had a tiny little leaf on it so I brought it inside to try and get it to grow a little larger before I put it in the ground. The leaf started to die so I placed the entire thing in water and added a little peroxide. It has done really well and even has new leaves coming out. I tried to put it in a little seed starter pot with soil and it started to die again, so I placed it back in the water. Now I don't know what to do with it. It's about an inch long from top to bottom so like I said it's really little. Any suggestions??
