-
Seeds - Although
technically,
roses could be reproduced by seeds,
that is rarely the method chosen by the home
gardener. For one thing, since seed is the
mixture of two sets of parents, you don't always
know what you are going to get. Also, it would
take a fairly long time from seed to get a
flowering plant that you could judge for value
as a landscape plant.
-
Cuttings - Perhaps
the most commonly used propagation method for
backyard gardeners is through cuttings. You can
cut off a small piece of new-growth cane and
stick it in
perlite or
vermiculite. You might
add a little rooting
hormone such as rootone to
help the process. Keep the media moist to ensure
rooting. Remember that, if you are dealing with
hybrid tea roses, this method may have some
problems. Hybrid teas are generally not cold
hardy on their own roots. That is why almost all
of them are
grafted onto a hardy root stock. So,
new plants created from cuttings of hybrid tea
roses may not make it through winter at some
point down the line.
-
Grafting - This is
the process of taking a piece from a cane or a
bud of a rose i.e. the scion, and joining it
with a root stock of another type of rose. Most
often, this is done because the roots of the
hybrid tea are not cold hardy so they are
grafted onto the roots of a "wild type" rose
which is not noted for its flowers but has a
very hardy root system.
