They sound over watered to me. I would just leave them alone and not water them until they are dry again. If you expect rain, move them to a covered area so they don't get more water. I doubt cinnamon would prevent a bulb from rotting. The ones that have already started to rot can't be saved. You could try sliding the whole plant, dirt and all, out of the pot and leave unpotted to dry. Plant or slide back into the pot again once they are dry. I wouldn't plant in front of your sago palm either. A three foot sago palm is not large. I have one that is taller than I am (I'm 5'1") in front of my patio and I know it will get even larger. In a few short years your sago is going to be much taller and wider. I have a couple of callas in the ground that come back every year (I've lost a few too, but these two have been coming back for about 10 years) and I have two pots that I bought last year and they are in the same pots and are coming back up now. The potted callas spent the winter in the garage, but when they started sprouting a week ago, I moved them back outside. They didn't get any water all winter. Gardening is a lot of trial and error. For a $1 a pot, the lessons are worth the money especially if any survive. Callas are gorgeous and the cut flowers last at least three weeks. Good luck!

We are exspecting rain and I just moved them all into my greenhouse earlier today.

So it won't hurt them to leave out of the pot until they dry out? Should I at least pull the soil portions away where I had to pull rotted ones out?

I've tried to grow them years ago with no luck.....I'm sure that I over cared for them :( Thanks, Jeannie :)

Here's a few of the spotted leaf ones:

Thanks, Jeannie :)

Wow. You got a deal!!! Mine thrive on benign neglect. Some in the ground and some in 16 inch deep clay pot. Because of our unusual heavy rain this winter they are stronger (bigger leaves, taller) than ever. Shortly their leaves will begin to turn brown and they go into summer dormancy. Are you giving them deeper pots? And the ones that rotted --- were their tubers mush? Good luck.

I'm also z9aTexas. Callas here in South Texas are susceptible to the bacterial disease Erwinia that causes the bulbs to turn to mush. If they start to smell awful that is a sure sign of Erwinia. I have noticed that many of the ones sold at box store garden departments are infected on the shelves, I think mainly from overwatering (soak every morning whether they need it or not) and growing in too heavy a potting soil.

First thing you should do is move the unhealthy plants well away from the healthy ones (other side of the house). I have saved some by blasting them clean of soil, cutting away the mushy parts,letting them dry and then dipping in 3% solution hydrogen peroxide from the grocery or pharmacy and letting them dry again. This won't work if the entire top of the tuber has gone soft and all of the eyes are dead.

Incinerate or send out both the plant and potting soil with the garbage rather than throwing them on the compost pile.
