Good Article on Poa Controll
Not sure if this has been shared before - But I stumbled upon an article from March 2015 about controlling Poa from sports turf online.
Controlling Poa Annua in Sports Turf
First off, thanks for sharing the article -- it was a good read and provides a lot of helpful info.
Secondly, my primary attack against
Poa annua is hand-pulling every time I mow, which works pretty well on a lawn of no bigger than ours (12.5 ksqft) where there is only limited
Poa annua and I also use a pre-emergent at the end of summer and during the fall to try to prevent as much of a new crop as possible.
Lastly, though, your posting tickled one of my pet peeves -- referring to any specific kind of grass as just "
Poa" as this isn't the name of just one species of grass.
"
Poa" is actually a genus (broader category) of plants, with about 500 species of grasses which grow all around the world. See https://en.wikipedia.org/wiki/Poa
There are some species of
Poa that many of us like to have in our lawns (e.g.
Poa pratensis, which is Kentucky bluegrass), and also some species that are weeds for most of us (e.g.
Poa annua and
Poa trivialis). Just calling a grass "
Poa" leads to a lot of confusion when talking about control techniques, as the ways these different Poa spread and reproduce are quite different, meaning controls need to be different, too.
I think some of the confusion people on this forum and other places have about how to control "
Poa" is because they may be reading advice that somebody wrote about their "
Poa" which may have actually been about
Poa annua and try to use that technique to control the "
Poa" in their lawn which may actually be
Poa trivialis, and thus won't work.
My suggestion is not to refer to any grass species as just "
Poa." If it is too many words to type
Poa annua or
Poa trivialis and you need to abbreviate these, you will spread less confusion by referring to them as "annua" or "trivialis" (or even just "triv") instead of "
Poa".
Oops, I better step off the soap box again...
