Hi friends -- Last year I planted my first two ornamental grass plants ever
in a border bed in my back yard, and I guess because of all the rain we've
gotten this year, they have grown much wider in circumfrence than I
anticipated.. The two of them together are really too wide for the bed
they're in, so I'd like to decrease their size around the middle. What
would be the best way to accomplish this? Should I divide them in halves
and transplant the other halves elsewhere in my yard? If so, when would be
the best time? I'm in the Washington DC metro area, zone 7; the seed tops
have begun to separe, but as far as I can tell they haven't released any
seeds yet. My soil is heavily clay, but I've amended all of my beds so
everything I've planted has done very well with the exception of a couple of
dwarf euonymous bushes. The grasses currently get full sun exposure for
most of the day from late spring to early fall; I have two other beds in on
my property to which I could move some of the divisions. One is up against
the house (light colored vinyl siding) and gets full sun most of the day,
and the other gets full sun in the morning and filtered sunlight in the
afternoon. Any suggestions for me as to how to
trim/divide/transplant/whatever these grasses? Thank so much!
Better a bleeding heart than no heart at all.
This is a list of grasses which they can be. I recommend you do a search on the
cultivation of those grasses once you find out what you have. Some ornamental
grasses are very invasive and spread by runners. Some are clumping grasses
which max out in size, but can still get very large. I have a Miscanthus
sinensis 'Zebrinas' which is 8 feet tall. Here are some things for you to
search for photos and see if you can identify them.
Okay, Miscanthus is a clumping grass. The base can range in size two feet, to 5
feet in diameter. The upper spray of foliage much larger. My advice is to
leave them in place over winter. Do not cut anything off and just enjoy the
winter interest of the pale, tan grass plumes. In early spring you will notice
signs of life emerging. At that time, you can cut the whole plant to about a
foot tall. Take a good, strong garden fork and pry the whole plant up. With a
very sharp knife, cut out sections and pot them into containers or plant them
elsewhere, but in a small area, you may not be able to have two plants of this
size. You can give some away, or put them on the compost pile. Either way, you
can do this work in the spring.
Another tip on growing ornamental grass is to do what called "combing" the
center. Every few years I have to go in and comb out the center of my
ornamental grasses. In the center there may be some rotting stems or the stems
may be so bunched together it can prevent any new foliage emerging. I
especially do this on plants known as sedge, but are also referred to as
grasses. Cutting those to the ground is almost like killing the plant! They
should ONLY be combed and not cut back.
Anyway, I may be confusing you.

When you search, enter "ornamental grass cultivation"and you will find a lot of
I'm in zone 7, the Washington DC area. We don't get all that much snow, but
it does snow usually a couple of times during the winter, just not all
winter long, and we rarely have snow on the ground for an extended period of
time. What do you think?
