I was in a propagation fever the other day, so
I trimmed a lot of my leggy scenteds. I was out of peat and potting soil,
so I just used pure vermiculite.
It was a disaster. I have never had
black leg before, and now more than half the cuttings--maybe more--have
died. Is this a common problem with vermiculite only rooting? Could
it be the lack of bacteria from the peat and potting soil that allows the fungi
to grow? Geesh.
