With a few of my paphs I have the following problem: the new roots coming from the base of the plant start out OK and then the growing tip goes brown and the root stops growing. Usually this means the end of this new root. This usually happens when the root is only about 1 cm (half an inch) long. What follows usually is the root slowly becomes darker spreading back up to the base of the plant ... then this black crusty growth covers the surface ... which I guess is some fungus. Mostly this doesn't lead to basal rot but surely the plants that get this are not happy.
I have only been able to come up with a few guesses as to what causes this:
(1) somehow the "chemistry" of the medium is wrong and the root tip gets "burned" ... although I tend to under-feed my plants.
(2) mites bite the root tip ... I do have mites but the only ones I've seen with my lens are the larger fast moving predatory kind ... then fungus attacks the root.
(3) some sort of black fungus attacks the roots without the help of mites ?
I'd be grateful for any suggestions.
Cheers,
Tim
