Grassy Weeds


Crabgrass

Crabgrass is a summer annual grassy weed. Seeds usually begin to germinate in late April to early May. Pre-emergent applications made prior to this time are generally effective in controlling this weed. We often see a good crop of crabgrass and other annual grasses in late summer, as pre-emergent applications begin to weaken and fail. This is why two applications of pre-emergent, properly timed, are usually recommended. A short mowing during summer can also lead to an outbreak of these weeds. Crabgrass dies in the fall.

Foxtail

Foxtail is a summer annual grassy weed. It is easy to identify by its seed head. It also has a reddish color at the base of the plant that can identify it when the seed head is absent. Foxtail seed germinates later than crabgrass but is also one of the annual grassy weeds that can be controlled with properly timed pre-emergent applications.

Goosegrass

Goosegrass is a summer annual grassy weed. It often appears in compacted areas. This weed is commonly seen on high traffic areas at a golf course. It has a white color at the base, and will tend to lie flat when young. It can be controlled with a properly timed pre-emergent application.

Nutsedge ("Nutgrass")

Nutsedge is a common weed problem. It is actually not a grass, but belongs to the sedge family. It's called watergrass, nutgrass, and a number of unprintable names. It is noted for it's shiny green color, and exhibits a rapid growth rate. It often sticks out like a sore thumb soon after the lawn is mowed. This weed is most common on well watered lawns, but can pop up anywhere when good soil moisture is present. It's native habitat is wet and marshy areas. There are now good products available for Nutsedge control, but it still requires vigilance to fully eradicate.
