The weed has been spreading in my yard quickly. I used a general weed
control liquid bought from Wal-Mart last year, but seems not working.
What kind of weed is this? Do we have to use something special to handle it?
It's not crabgrass which has barely begun to germinate in much of the
US and doesn't look at all like your picture. Crabgrass won't appear
this size till late summer. Yours looks like some type of rough
grass. Which is the bad news, because with some specific exceptions,
there aren't herbicides that will kill the undesirable grass without
killing the good grass too. As you've already found, the typical
broadleaf weedkiller doesn't work, because it's not a broadleaf weed.
You can take a sample to a local agricultural extension service, if
they have one in your county for identification. IF you do, take as
large and mature a plant as possible. But, assuming it's a perenial,
it's very likely that the only way to get rid of it will be to use
Roundup to kill everything and re-seed. If it's just a few plants,
you could also dig it out. Hopefully it's not all over your turf.
Very hard to tell from the picture, but it looks a lot like perennial
rye grass. A neighbor planted some a few years ago to have a green
lawn over winter. Now it's spread over the whole neighborhood & I've
been fighting it all spring. Broadleaf weed killer doesn't phase it.
Thank goodness it's shallow rooted so it can be pulled up by hand.
It's not Perennial Rye grass - which is distinguished by having a very
shiny surface - amongst other things. (Looks a bit like a
'Holcus' (Yorkshire Fog her in the UK :-) )
If there is not toooooo much of it about, a neat little trick is to
bunch up the weed gradd into a tube - dpending upon the size of the
clump, then spray Roundup (Glyphosate) down the tube onto the weed
grass. Sure. a little will probably find its way onto surrounding
grasses, but nothing that some overseeding can't sort out. Otherwise,
just bunch it up and cut it down into the guts of the root system. You
may then find that it is not quite the massive job to dig out the
Hope this helps
For isolated weeds, put on a surgical glove, then a disposible cotton
glove over that. Wet the cotton glove with the chemical, and carefully
wipe your hand over the weed. You have lots of control this way.
For widespread weeds, wrap a flat-ended rake with old cloth, dip the cloth
in the chemical, and carefully rub it over the weeds. This only works if
you let the weeds get taller that the surrounding plants. It will also
require multiple applications, because you aren't getting the chemical
over the whole plant.
Many years back Ortho made a wax based bar impregnated with
herbicide. You attached it to your mower and dragged it as you cut
the grass. It worked very well but didn't stay on the market very
long. Guess someone had a problem with getting weed killer on their
