I have had problems over the years with a stump rot which starts with a
foamy watery solution oozing from the main root. It continues to ooze and
eventually stops, and by that time the main root has rotted. I have talked
to a few growers who have had it also. Don Black told me he thinks it is
caused by overhead watering which splashes up some nasty fungus on the main
root, causing the infection to start. Howard Shelley had it on one of his
plants this year. I water overhead so I think that is probably the cause.
From now on when I water overhead I cover the main stump first. It seems to
be working. I have not been able to find anything about this oozing
condition in any books. If anybody knows anything about it I would
appreciate their input. Pete Glasier
