Do not use Hormone Rooting Powder on Pelargonium it can have side

I wouldn't dream of it, but can you tell us the side effects? I
haven't heard about that.

With Pelargoniums it causes splitting and rotting of the stem base, plus if
used incorrectly hormone rooting powder can act like weedkiller, I have
found during the season its not really necessary but often has a fungicide
in with it that is of benefit. To be any use at all it has to be fresh.
