现撒了草种的地方长了很多这样的草。
长得飞快。1个星期就开始结籽了。
应该是weed的一种吧?怎么杀啊?
今年开春的时候scott的Crabgrass Preventer和那个Weed and Feed都撒了的

I did some more reading and found that the 'absent of ligule' claim in
Kentucky Bluegrass (KBG) is incorrect. KBG could have ligule as well, but
it is short and like a collar which is kind of squared, while the Poa Annua'
s ligule is longer and pointed. Poa Annua is generally light green in color
(easy to spot) and has thin and weak stems.
