I seed my yard twice a year as I'm suppose to, I also water and fertilize as
directed. Lately I'm noticing the grass blades in some areas are no longer
the nice tall thin blades, but more to the short fat blades. I'm concerned
because A: it doesn't look nice and B: I'm hoping its not some sort of weed
growing. Can anyone offer me some advise?
If it is a light green grass, it is probably crabgrass. It's important
to use a liquid crabgrass killer now before the weed drops its seeds.
Those seeds will sprout next year, so use a pre-emergent crabgrass
killer in the early spring, too.

Sorry. I can't tell you what happens when you mix these things. I use
the liquid crabgrass killer in a pump sprayer so I can walk around and
be very selective about the application. Three applications are needed
about 7 to 10 days apart.

this what Fescue looks like? If so, how do I get rid of it?
A pic would be *most* helpful.
If it's fescue, I can't understand why you'd want to get rid of it.
Besides, you most likely planted it. But, you haven't stated *what* seeds
you planted. Looking for something to spray all over your lawn without
having a *positive* ID on the plant, is just plain rediculous.
Again, a pic is really needed.

It's an annual. It will die when it gets cool. You could go to the trouble
of treating it, which will take a couple weeks. Then you'll have this nice,
yellow/brown crap all over your yard for a few weeks until it would have
Next spring, put down a good pre-emergent for it.
how much physical labor are you willing to
apply in order to have a nice green lawn?
the reason I ask is because there are several
approaches to control and eradication.
1: to pull up by the roots
if you end up making the choice to use a selective herbicide
at this stage of the growth shown in your pictures, you'll end
up with one ugly lawn. the treated crabgrass will first go yellow
and then go brown. then, after the crabgrass is dead you'll have
a bare spot for awhile since most selective herbicides used on
fescue retard the growth and spreading of the fescue.
if you work your fingers under the crabgrass you'll find several
runners all going back to the same root source. after several
mowings of crabgrass the runners will put down roots of their own.
if the runners have not put down roots pulling the source root is
not all that difficult. takes some time. wet the ground and it
will be somewhat easier.
if all the above seems to be the incorrect choice for you. do an
over seeding with fescue seed in the early fall when you notice the
HOT weather crabgrass beginning to go DORMANT. pamper your new seed
with some starter fertilizer and adequate water. in the very next
spring before your air temps get high enough to bring the crabgrass
out of it's DORMANCY, as well as sprout all the seeds it made and
dropped into your lawn, apply a good quality at the correct quantity
of a pre-emergent designated for crabgrass.
good lawn care is always filled with choices.
I agree that at least some of it looks like crabgrass, though I'm not
sure it's all crabgrass. There may be some other weed type grass there
as well. Af riend of mine has a rough blade type grass growing here in
NJ that goes from brown to green this time of year. And whatever it
is, it's not crabgrass.
I agree with Jim, if you kill it now, it will look bad for a few weeks
as the crabgrass dies. The optimum time to kill any crabgrass that
escaped pre-emergent treatment was a few weeks ago, when the plants
were still small and easier to kill.
On the other hand, leaving it there, it will continue to grow, still
look pretty bad and choke out desirable grass until first frost. So,
it's a mixed bag as to what to do.
Acclaim is effective and what I use, but at this point you will need 2
treatments to kill it. Also, don't apply any herbicide when it 85+ out
or the grass is stressed from lack of water.
I agree with others, re crabgrass, with maybe some other coarse fescues.
I wish my crabgrass/fescue/clover/weed lawn looked as nice and green as
yours. If I were to kill the crabgrass & clover now, what little green I
have would be gone.

Crabgrass,Crabgrass, Crabgrass and Crabgrass. Keep it cut to keep it
from seeding. Old man winter will kill the plants you see. Since you
have a good crop of it, there more than likely are plenty of
ungerminated seeds that will haunt you in the next early summer. Apply
a pre-emergence herbicide of your choice to keep them from
germinating. Always areate in the fall because the seed that you
expose will die because of cold weather. If you areate in the spring,
you will have a bumper crop of crabgrass. Hope this heps!
