Black stuff on roots?
I have a couple of plants aerial roots that have black on them. I doesn't
just wipe off? Any thoughts on what to do? Cheers Wendy |

C'mon Wendy. You know the response: "describe the conditions," etc., etc.
"Black stuff" that doesn't wipe off isn't all THAT helpful. -- Ray Barkalow - First Rays Orchids - www.firstrays.com Plants, Supplies, Books, Artwork, and Lots of Free Info! .. . . . . . . . . . .

Uh....Wendy....were you spray painting the lawn furniture black again?
Could it be mildew? "Wendy" wrote in message news:hKPYa.40514$Ne.39623@fed1read03... I have a couple of plants aerial roots that have black on them. I doesn't just wipe off? Any thoughts on what to do? Cheers Wendy |

*g* Oh yes Gene, that's what it looks like the mildew that you see on patio
furniture! It is not powdery like mould & won't just wipe off? So what do I use for mildew? Cheers Wendy "Gene Schurg" wrote in message hlink.net...

I'd start with something like physan or maybe a weak bleach mix.
Physan we know is safe and bleach is generally safe. Maybe someone else has an idea of what concentration would be safe. Or if the plants aren't suffering just let them grow and when the weather gets dry the mildew will die.

Thanks guys, will try the Physan, I always have a diluted solution in a
spray bottle hanging around. If it doesn't work, I try the Daconil? Cheers Wendy "Jim S" wrote in message news  try daconil "Wendy" wrote in message news:hKPYa.40514$Ne.39623@fed1read03...

Hi, Wendy,
You might try a tiny drop of Physan 20 (most nurseries have this) in a pint spray bottle. Spray the roots and then be sure to wash off (although I have never had any ill-effects from spraying the greenhouse walls with diluted Physan). .. . .
