What is the best herbacide to use to spot treat and kill the foreign grass?
You will need to first identify exactly what species of grass it is that you are trying to eliminate. We can not make a recommendation based solely on the information you provided as each herbicide can be extremely specific to the needs of your lawn. Take a sample of your lawn to a local lawn company or master gardener in your area to get it identified. Once you know what you are trying to eliminate, we can find a product to meet your needs.
