The lawn weed, crabgrass (Digitaria spp) is a warm-season annual weed, which means it reproduces by seed. People often ask me how to kill crabgrass. The short answer: applying preemergent herbicides at the right time is the best way to kill crabgrass.看了一下网站,说他是annual的,今年不管了,等明天春天做 好预防工作吧。太难除了,现在。
root won't die, and very hard to kill

In temperate climates, the crabgrass will grow two years. It also spreads by putting out runners, w
