annual and member of the grass family, Foxtails can sometimes be found
in lawns that do not see proper cultural practices, meaning the grass
tends to be cut very short, the soil is dry and compacted and lacking
nutrients. A mature Foxtail plant can grow as high as 3 feet tall, and
tends to grow in clumps, rather than spreading like some weeds like to
do. Its leaves spiral and are long, and its flower heads are yellow and
bushy, like the tail of a fox, hence the name.
its membership in the grass family, a broadleaf weed control product
will not control this weed. Options are to dig out the weed and replace
the soil and grass, or treat chemically with a non-selective herbicide.
Any herbicide containing glyphosate will work. The problem with using
these herbicides is that they are NON-SELECTIVE meaning all growth with
chlorophyll (anything green) in it will die once it comes in contact
with the herbicide. We cannot stress this fact strongly enough.
If you are determined to use a herbicide with glyphosate to control
Foxtail you MUST BE EXTREMELY CAREFUL not to come
in contact with any growth other than the Foxtail. If you apply a
non-selective herbicide to the entire lawn to control the Foxtail, your
entire lawn WILL DIE.
