Easy Fall Propagation Techniques |
As a
home gardener, fall should be a very
special time for you. Fall is the best
season of the year for plant
propagation, especially for home
gardeners who do not have the luxury of
intermittent mist. The technique that I
am going to describe here can be equally
effective for evergreens as well as many
deciduous plants.
The
old rule of thumb was to start doing
hardwood cuttings of evergreens after
you have experienced at at least two
hard freezes. After two hard freezes the
plants are completely dormant.
However, based on my experience it is
beneficial to start doing your evergreen
cuttings earlier than that. So instead
of doing “by the book” hardwood cuttings
you’re actually working with
semi-hardwood cuttings. The down side to
starting your cuttings early is that
they will have to be watered daily
unless you experience rain showers. The
up side is that they will start rooting
sooner, and therefore are better rooted
when you pull them out to transplant
them.
To
prepare an area in which to root
cuttings you must first select a site.
An area that is about 50% shaded will
work great. Full sun will work, it just
requires that you tend to the cuttings
more often. Clear all grass or other
vegetation from the area that you have
selected. The size of the area is up to
you. Realistically, you can fit about
one cutting per square inch of bed area.
You might need a little more area per
cutting, it depends on how close you
stick the cuttings in the sand.
Once
you have an area cleared off all you
have to do is build a wooden frame and
lay it on the ground in the area that
you cleared. Your frame is a simple as
four 2 by 4’s or four 2 by 6’s nailed
together at each corner. It will be open
on the top and open on the bottom. Just
lay it on the ground in the cleared
area, and fill it with a coarse grade of
sand.
This
sand should be clean (no mud or weed
seed), and much coarser than the sand
used in play box. Visit your local
builders supply center and view each
sand pile they have. They should have
different grades varying from very fine
to very coarse. You don’t want either.
You want something a little more coarse
than their medium grade. But then again
it’s not rocket science, so don’t get
all worked up trying to find just the
right grade. Actually, bagged swimming
pool filter sand also works and should
be available at discount home centers.
Once
your wooden frame is on the ground and
filled with sand, you’re ready to start
sticking cuttings. Wet the sand the day
before you start, that will make it
possible for you to make a slit in the
sand that won’t fill right in. In this
propagation box you can do all kinds of
cuttings, but I would start with the
evergreens first. Taxus, Junipers, and
Arborvitae.
Make
the cuttings about 4” long and remove
the needles from the bottom two thirds
of the cuttings. Dip them in a rooting
compound and stick them in the sand
about an inch or so. Most garden
centers sell rooting compounds. Just
tell them that you are rooting hardwood
cuttings of evergreens.
When
you make the Arborvitae cuttings you can
actually remove large branches from an
Arborvitae and just tear them apart and
get hundreds of cuttings from one
branch. When you tear them apart that
leaves a small heel on the bottom of the
cutting. Leave this heel on. It
represents a wounded area, and the
cutting will produce more roots because
of this wound.
Once
the weather gets colder and you have
experienced at least one good hard
freeze, the deciduous plants should be
dormant and will have dropped their
leaves, and you can now propagate them.
Just make cuttings about 4” long, dip
them in a rooting compound and stick
them in the bed of sand. Not everything
will root this way, but a lot of things
will, and it takes little effort to find
out what will work and what won’t.
This
is a short list of just some of the
things that root fine this way. Taxus,
Juniper, Arborvitae, Japanese Holly,
Blue Boy/Girl Holly, Boxwood, Cypress,
Forsythia, Rose of Sharon, Sandcherry,
Weigela, Red Twig Dogwood, Variegated
Euonymus, Cotoneaster, Privet, and
Viburnum.
Immediately after sticking the cuttings
thoroughly soak the sand to make sure
there are no air pockets around the
cuttings. Keep the cuttings watered once
or twice daily as long as the weather is
warm. Once winter sets it you can stop
watering, but if you get a warm dry
spell, water during that time.
Start
watering again in the spring and
throughout out the summer. The cuttings
should be rooted by late spring and you
can cut back on the water, but don’t let
them dry out to the point that they burn
up.
By
fall you can transplant them to a bed
and grow them on for a year or two, or
you can plant them in their permanent
location. This technique takes 12
months, but it is simple and easy.
