Dave, mine did the same thing, so I left mine floating for a while until
they recovered and then only planted a small portion of the roots. It
appears to be doing OK will know more later.

My lobelia cardinalis plants were rotting at the base of the trunk...they
formed reddish brown blotches on the trunks where leaves used to be. One
plant was detatched from it's "trunk" and floating, the other plant came
out
easily from the substrate (these plants were planted about a month ago)
The
third one seemed to be anchored down securely so I left it...hopefully it
has established good roots. I pinched some daughter shoots off one of the
plants and planted these. It's weird why they were rotting since the tops
were growing slowly but well. I trimmed the rotting stuff off the trunks
and
replanted. Why did this happen? Did I bury too much of the trunk? (2
inches)

Thanx for any opinions and help!
