Karl and others, if you go back in the medit plant archives, I think
you will find a messge that someone sent about a research project
that had been done on euc leaf mulch. The results showed that the
mulch actually stimulated growth rather than inhibited, disproving
the long-held myth that leaves produce growth inducing hormones.
The study also (and I don't recall how) suggested that the roots
inhibit growth by way of their being so dense and close to the
surface rather than by synthesizing an inhibitory compound.
