I regularly exhibit rosemary cuttings in water at the local fair, which
takes place in early September. I strip off the bottom leaves of the eight
inch cuttings before putting them in the water. (A requirement for
exhibition is no leaves below the water.) After sitting in water for five
days in a warm room, usually one or two of the three cuttings has sent out
roots. When put in soil, all the cuttings survived. I keep them inside in
the garage window for the winter. The cuttings will not survive the winter
if planted in the fall.

I found heel cuttings root best in winter in a light porous mix in very
cool
temps. From a cut stem, rip side braches downward taking a piece of the
parent stem with it. I use rooting hormone, stick in a flat that's
probably
half perlite, half peat. Keep the nights above freezing and days in the
40's. Do not allow to dry out or flood. You'll always have some that don't
root, but most will in about 2-3 months.

Does anyone know how to propagate rosemary by stem? I live in
Vancouver, Canada and have tried a few times with no success. The
stem and leaves just turned black after a few days. Thanks in advance
for your feedback.
