Grassy weed identification

Asked August 18, 2020, 12:32 PM EDT

Is it crabgrass? Most is not the clumpy stuff I'm used to. Or other? It appeared this year (1st time in 18 yrs) all over our townhome community. We are wondering whether landscaper failed to apply pre-emergent last spring.

This looks like crabgrass based on the photos. If the landscaper applied a crabgrass preemergent, it is possible that it may have leached out due to all the rain we received this season.
Other factors include how many applications were applied according to the label, etc. Here is our page on crabgrass and management in lawns https://extension.umd.edu/hgic/topics/crabgrass
