Question: I was unable to find information
on two problems we're having with our
lawn. The nutgrass seems to be uncontrollable and multiplies
like crazy, and we have.....I believe it's called Dollarweed,
or dollar clover? It, too
spreads. We have St. Augustine grass. It's likely we've
added to our problem by not bagging the grass and rather
using the mulching feature on the mower. Seems to me that
only spreads the seeds around. I do have one other weed
I would like help with, so I would be happy to contact you
if you will give me a phone #. Any suggestions on how to
get rid of these menaces? Thanks in advance for your help.
After I sent you the last email, it dawned on me to send
you a picture
of the weeds I'm describing. Particularly the one on the
right with what looks like a "burr" at the top.
I'm thinking this is also nut grass, but I haven't seen
the burr on the nutgrass in my flower beds, only on the
ones in my St.Augustine.
Answer: The one weed with the round leaf
blade is definitely dollarweed.
Unfortuntely, this is a very difficult weed to control.
applications of the three-way herbicides such as Ortho's
Southern Grasses will do a fair job. There is a herbicide
or Blade which will do a pretty good job on this weed. At
this time I
am not aware of any products sold in garden or retail stores
these chemicals in them.
The weed with the little bur is one of the sedges, probably
Kyllinga. Either Image or Manage can be used to control
Kyllinga. I hear that the Image works a little better on
than Manage. Be careful to not over apply the Image, because
discolor or burn your St. Augustinegrass.
