Rose Propagation
So, you have a huge, well-established, beautiful rose bush growing in your
yard. It is a unique bush, and has been producing a profusion of blooms on
a regular basis for years. This year's blooms are no exception. Life is good.
There is only one problem.....you are about to move.
A fully grown rose bush is not an easy item to move. This is just one example
of many, where plant propagation comes in handy. Propagation is simply the
act of reproduction, a common term in the plant world. Roses are propagated,
or reproduced, either by seed or by taking cuttings from an existing bush.
Either method is effective. Seeds will take on a genetic mixture of two mated
plants. The pollen that fertilizes the flower might not have come from the
plant with the flower on it. A cutting however, is an exact genetic
replica of the plant it was taken from.
Taking a cutting from an existing bush, is by far the most common method
of propagating roses. Although you can do it, growing new rose bushes from
seed, is largely in the realm of commercial growers and horticulturalists.
We will focus upon the first method.
How to grow new roses from cuttings:
Propagating roses from cuttings is best done in the spring, when the plants
are vigorous and the weather is cooler. Select a young, tender shoot . Old,
woody stems will seldom root well. Look for one that does not yet have a
bud on it. If there is a bud, snip it off carefully. With a sharp knife,
cut the shoot four to six inches long. Plant the cutting one to two inches
deep in your flowerbed in an area clean of weeds and other plants. Ideally,
it should be placed where you want it to permanently reside, and avoid the
possibility of transplant shock from moving it at a later date. Water it
well, and cover with a glass or plastic jar or container. The jar acts as
a mini-greenhouse, encouraging better growth by keeping the temperature higher,
especially at night, and retaining moisture and humidity.
The success rate of cuttings can be low for a number of reasons, especially
for new and inexperienced growers. We recommend you start three or four cuttings.
If they all develop, you can replant the extras, or give them to a greatful
friend.
Check on your new rose bush every several days to make sure there is enough
moisture in the soil. Water if the soil appears dry. Remember, the new roots
will not be deep. Use of a little liquid fertilizer will help, but is not
a requirement. Remove the jar from the plant during the daytime, if the
temperature approaches 75 degrees or higher.
Do not worry if the shoot appears dormant for a while. All of the activity
is really happening underground. It is focusing upon developing a root system,
and does not have the energy or root support to develop new growth. After
a couple of weeks, the shoot will begin to grow.
Once the new rose bush has begun to grow, you can remove the jar you placed
over it. Follow normal care and maintenance for
the new bush from this point forward.
Important Note: Just so you are aware, while propagation is commonly
practiced, it is actually against the law to propagate a patented hybrid.
Propagation from Seeds:
Yes, like other flowers roses produce seeds. Many people are not aware of
this, as the rooting of cuttings is by far the most popular way of propagating
new rose bushes.
Leave a spent rose on the bush, and around bulb-like "Rose Hip" will
form. The seeds are inside of the rose hip. Let the rose hip completely dry
out before harvesting seeds.
We recommend starting rose seeds indoors in late winter or early spring.
As the weather warms, you can plant rose seedlings outdoors in their permanent
home.
