Lawn Weeds #264301

Asked July 23, 2015, 12:50 PM EDT

Mr. Stensaas brought in these two plants from his lawn.  We decided one was clover but are there varieties and what can be used to kill?   The second plant is either crabgrass or brome grass. We couldn't decide. If it is crabgrass, does preventer need to be put down in spring or fall?  Thank you.

Hello,

You are right about the clover and the other is crab grass. I have attached the Lawn  weed control guide.  The second page has a table that will help you decide what and when to spray on the lawn to control both of these weeds and for future reference for any other weeds that may become a problem.

Thanks,

Connie
