Using
the Propagation Technique Known as Budding to Grow Beautiful
Ornamental Trees

Flowering
Dogwood trees can be easily grown from seed, however 99.9999% of
the seedlings that sprout will be Cornus Florida, which is White
Flowering Dogwood. It doesn’t matter if you collect the seeds
from a White Dogwood or a Pink Dogwood, the seedlings are likely
to be white.
The only
predictable way to grow a Pink Dogwood, Red Dogwood, or one of
the beautiful Dogwoods with variegated leaves, is to bud or
graft the desired variety onto a White Dogwood seedling.
That’s why the botanical name for Pink Dogwood is Cornus
Florida Rubra. Cornus means Dogwood, Florida indicates White,
Rubra indicates Red or Pink. Cornus Florida Rubra indicates Pink
Dogwood grown on White Dogwood rootstock.
Between budding
and grafting, budding is the most common technique used in the
nursery industry. Grafting is usually done in the late winter
months when the plants are dormant. When you graft a plant you
remove a small branch (4 to 6 inches) from the desired variety,
trim the end of the branch to expose the tissue under the bark
and then trim a taper on the end. You then trim the seedling in
such a way to match and receive the branch you are grafting on
to it. Timing, temperature, and humidity are all critical to the
success of the procedure, which is usually done in a greenhouse.
Budding is much
easier, and does not have to be done in a controlled
environment. Most budding is done later in the summer when the
bark on the seedling slips easily. That means that when a cut is
made in the bark of the seedling it can be easily pulled away
from the tissue layer under the bark. This tissue is known as
the cambium layer. Here in the north Crabapples and other fruits
are usually ready to bud around mid to late July, while Dogwoods
are not ready until late August.
Unlike grafting
where you use a small branch to attach to the seedling, when you
bud you insert a single bud under the bark, budding is usually
done down low on the seedling, very close to the soil. You can
bud up higher, but any new growth that appears below that bud
must be removed because it will be identical to the rootstock
and not the desired variety.
The budding
process is quite simple. Just clip a branch from the tree of the
desired variety, this is known as a bud stick because it has
many buds that can be used for budding. The buds can be found at
the base of each leaf. Look closely where the leaf emerges from
the branch and you will see a very small bud. In the fall when
the tree goes dormant the leaf will fall off, and bud will
remain. The following spring the bud will grow into a new
branch.
When you slip
that bud under the bark of a compatible seedling, it will grow
the following spring just as if it were still on the parent
plant, with all of the qualities of the desired variety. All
most all fruit bearing and ornamental trees are grown this way.
Just make a
“T” shaped cut in the bark of the seedling. A horizontal cut
about ¼” long, with a vertical downward cut about ½” long.
The two cuts should intersect at the top of the “T”. Don’t
cut into the cambium tissue, just slice the bark and open it up
slightly with your knife or razor blade. Now you are ready to
remove the bud from the bud stick.
First clip off
and discard the leaf from the bud that you are about to remove.
When you remove the leaf, leave the stem attached to the bud
stick, just remove the leaf itself. The stem makes a nice little
handle to hold on to. To remove the bud from the bud stick just
cut into the bark and under the bud, it should pop off easily.
Again, don’t cut into the cambium tissue, but make sure you
are under the bark so you don’t damage the bud. Along with the
bud you will have a small piece of bark shaped like a tiny
banana peel, and the stem from the leaf.

Holding the bud
by it’s handle (the stem) slide it into the “T” shaped cut
you made on the seedling. Make sure you put it in right side up.
The stem and the leaf should protrude through the slit, and the
stem should be pointing toward the sky at an angle. Push the bud
all the way down into the slit by catching the bark, (Not the
Bud) with the tip of your knife.
Now cut a rubber
band so that it is no longer a loop and wrap it around the
seedling to close the opening so dirt, water, air, and insects
can’t get in. Make a wrap below the bud, and a few wraps above
the bud. Use a rubber band approx. ¼” wide, and be careful
not to wrap too close to the bud, nor to tight.
You don’t want
to strangle the seedling, it needs to be healthy and happy so
the new bud will bond to the cambium layer. Leave the rubber
band on until early spring, at which time you should remove it,
and clip off the top of the seedling just above the bud. As the
plant comes out of dormancy the bud will begin to grow into a
new branch just as if it is still attached to the parent plant,
except that now it is going to grow upright and form the stem of
a tree.
When this new
growth reaches a height of 3 to 4 feet, clip the tip off, this
will force it to start putting on lateral branches. Once these
lateral branches are 18” long or so, you can remove all the
growth from the stem below where the lateral branches start. Now
the plant should look like a beautiful little tree. And that
makes you the proud parent!
With all of that
said, today it is possible to grow Pink Dogwoods by rooting
cuttings under intermittent mist, however, it is tricky, and my
few attempts have failed. ??? Most nurseryman still bud them.
