andy I had a similar situation with a parlor palm, kind of similar growth habits. I would bring the palm inside in a nice bright window, but not so close to the window that you burn the palm. Let it dry out between waterings. When you do water it, let the water drain thru and then dump whats in the saucer.

Sounds like at least one of yours has resprouted. I had a clump in ground ( that froze solid when the heater failed in the GH ) After cutting them off at ground level, two of them have regrown. The other stems/ roots shouldn't be a problem, maybe just cut them down to soil level.

Thank you guys. I don't have a saucer below it. I have it next to my lilac tree so it wouldn't bake in full sun. The one plant that's making a comback is pushing out its 5th frond since May. It is loving all of this rain that we keep getting. I'll try treating the funky parts with a fungicide.

If you fellows are discussing Chamaedorea cataractarum, it grows on cataracts in rapid streams and is difficult to overwater. The best specimen I ever had was under a propagating mister with no attempt at draining. My apologies if not cataractarum. - merrill

Merrill-
It is exactly the one you mentioned. I guess I'll just see if the other three grow out. It dose look a little silly with only one of the four still standing. That one though is reaaly making a great comeback.

P. S. to andyandy:
My cataractarum suckered heavily; probably ten meristems. - merrill

Merrill-
Do you think it may be 1 plant not 4?

andyandy:
If some meristems are sick and some not, you may have separate plants. - Good Luck, merrill

They were sick because of neglect. It (they) were sitting in a grocery store parking lot getting, no water, food, or sun. I bought it in October so there was no summer left to bring it back. That one keeps going gang busters though.
