How to Grow Ornamental
Grasses

Ornamental grasses have become extremely popular in the past
ten years or so, and if you buy them at a garden center they
are kind of pricey. Learning how to grow them yourself is
actually quite easy. They can be grown from seed, but I
won’t pretend to be an expert at that for several reasons.
One, I don’t know anything about growing them from seed, and
two, I have no desire to propagate them from seed because
seedlings require too much care.
The easiest and most effective way to propagate them is
through simple division. Of course you will need at least
one parent plant of each variety that you would like to
grow. If you shop around you might be able to find some 4”
inch pots at a fair price.
One of each variety is good for a start. I find that the
best time of the year to divide them is in the spring, just
before the new growth emerges. If you buy the stock plants
in the early spring, you might be able to divide them right
away. If you buy them at any other time of the year, just
plant them in your garden or other suitable location,
knowing that you are going to dig them up in a few months,
or a year or so.
When spring arrives you can divide them at any time as long
as they are not well into putting on new growth. The earlier
the better. To divide them simply dig up the root mass and
start dividing it into pieces. The divisions do not have to
be to be very large. It’ difficult to describe, but as long
as you have some roots, the new plant is likely to grow.
If you have small young plants you can probably just tear
the root mass apart with your hands, but if the root mass is
very big then you are going to need some tools. You might
need some heavy duty tools!
Last spring I divided several grass plants that had been in
my landscape for a few years. When I dug out the root mass
it was much larger and more dense than I expected. Using a
very good digging spade and some real elbow power I was able
to chop the root mass into quarters, and I replanted the
quarters back into my landscape. That still left many clumps
that I wanted to divide into very small plants that I could
pot up in 2 quart containers.
The root mass was too dense to tear apart with my hands, so
I literally got a hammer and a 4” wide mason’s chisel and
chiseled off pieces. It worked and I now have a couple of
hundred beautiful little grass plants in 2 quart containers.
Since then I have talked with a friend of mine who works for
a large wholesale grower, and he told me that you never want
to let an ornamental grass plant get that big if you intend
to divide it. He said they plant small divisions in the
field in the spring, and dig them up the following spring
and divide them again. He assured me that if you get them
just 12 months later, they can be easily torn apart by hand.
That sounds like a lot more fun than what I went through! |
