Hello everyone! Thanks so much for all the great replies.
My name is Rob. I live in Northern VA.
The potting medium is a mixture of potting soil, sphagnum and peat moss, and orchid bark. Florida Hill Nursery recommends a 50/20/20/10 mix.
I followed Hetty's advice and placed the planters in trays on top of stones with water in the tray.
These planters do not have the bottom sitting in the water reservoir like the water spa planters. They are 8" planters.
The water is drawn up to the roots via two pieces of cloth.
So, while I may think I have not over-watered them and that I do not have a case of root rot I will do as Evan and Lin suggested.
I'll check the roots today when I get off from work :-).
Evan had asked if these have ever been outside and the answer is no. They were placed in temporary pots when I got them from the nursery and put near an artificial light.
Once the self-watering planters arrived I re-potted them making sure that I kept the sane ratio of potting medium.
I agree with Evan about raising them as indoor plants being a pain. My wife is going to beat me if I kill another one :-)
Most of my experience has been with Clivias.
I really like colocasias bur have never had any luck with them but the Marine in me will not allow me to quit :-)
Thanks again for all the great advice. I will post my findings later this evening.
Rob
