I still have my jar of Rotenone back from 1970. *

Slightly different chemical.

I have kept it clean
by putting a little of the powder onto paper, using that on the
cuttings, then discarding the paper. The directions say not to dip
cutting directly into the jar (makes sense). *


Spreads disease. Better just to waste 1/2 tsp than a tray
of the cuttings you thought were worth the effort to root.

I have tested the
effectiveness using coleus cuttings and it is still good.


Coleus is already fast. It rooted faster with Rootone?
