Goodmorning,, My name is Nisar with Green Lawn Fertilizing. Today I completed your Round 1 Application. This application consists of a pre-emergent crabgrass control which is designed to form a barrier under your soil that will help prevent the germination of crabgrass seeds in your lawn. I’d really appreciate if you could leave me a review on my service today. It would help me a lot with my work and future improvements. Thank you and have a blessed day.
