There are two kinds of winter gardening. The first
method usually starts in January as the gardening catalogs begin to
arrive in the mail. This type of gardening is as easy as sitting in
your favorite chair, browsing the catalogs, and either dreaming about
what you're going to do this spring, or actually drawing designs for
the gardens you intend to work on.
The second type of winter
gardening is to actually get out in the yard and do a little work. Of
course if it's bitter cold, you'd be better off waiting for a good day.
Winter is a good time to do some pruning if the temperatures are around
30 degrees or so. I don't recommend pruning if it's considerably below
freezing because the wood is brittle and will shatter when you make a
cut.
One of the advantages of pruning during the winter is that
you can see much better what needs to be cut out and what should stay.
At least that's true with deciduous plants. The other advantage is that
the plants are dormant, and won't mind you doing a little work on them.
Ornamental
trees should pruned to remove competing branches. Weeping Cherries,
Flowering Dogwoods, Flowering Crabapples etc. have a tendency to send
branches in many different directions. It is your job to decide how you
want the plant to look, and then start pruning to achieve that look.
But
first stick your head inside the tree and see what you can eliminate
from there. This is like looking under the hood, and when you do you'll
see a lot of small branches that have been starved of sunlight, that
certainly don't add anything to the plant. They are just there, and
should be cut out.
Any branch that is growing toward the center
of the tree where it will get little sunlight should be cut out. Where
there are two branches that are crossing, one of them should be
eliminated. Once you get the inside of the plant cleaned up, you can
start shaping the outside.
Shaping the outside is actually quite
easy. Just picture how you want the plant to look, and picture
imaginary lines of the finished outline of the plant. Cut off anything
that is outside of these imaginary lines. It is also important to cut
the tips of branches that have not yet reached these imaginary lines in
order to force the plant to fill out.
For the most part plants
have two kinds of growth: Terminal branches and lateral branches. Each
branch has one terminal bud at the very end, and many lateral branches
along the sides. The terminal buds grow in an outward direction away
from the plant. Left uncut they just keep growing in the same
direction, and the plant grows tall and very thin. That's why the trees
in the woods are so thin and not very attractive.
When you cut a
branch on a plant, the plant sets new buds just below where you cut.
When you remove the terminal bud the plant will set multiple buds; this
is how you make a plant nice and full. Don't be afraid to trim your
plants, they will be much nicer because of it. The more you trim them,
the fuller they become.
Lots of people have a real problem with
this. They just can't bring themselves to prune. Especially when it
comes to plants like Japanese Red Maples. It kills them to even think
about pruning a plant like this. Just do it! You'll have a beautiful
plant because of it.
Look at the plant objectively. If you see a
branch that looks like it's growing too far in the wrong direction, cut
it. If you make a mistake it will grow back. Not pruning is the only
mistake you can make. I hope this helps and doesn't get you in trouble
with your significant other. Many a family feud has started over
pruning.
