No Mow Month 2025
This April, the Cumberland River Compact is encouraging residents of Davidson County to give their mowers a rest and let their grass grow! By participating in No Mow Month, you can improve water absorption in your neighborhood, reduce pollution, cut carbon emissions, and create habitat for wildlife.
Participants will receive a No Mow Month yard sign to display in their yard in the month of April.
Traditionally manicured lawns do not allow enough water to sink into the ground during peak rainfall events. Instead, this water flows over surfaces as runoff and carries with it oils from mowers, pet waste, fertilizers, and other pollutants that are harmful to nearby waterways.
When grass is allowed to grow taller, its roots grow deeper, allowing for more rainwater absorption and filtering out more pollutants. Even just a month of refraining from mowing will reduce erosion and runoff in your yard while replenishing our groundwater supply, helping to keep streams alive during drought periods.
Frequently Asked Questions:
How will I receive my No Mow Month Yard Sign?
If you register by March 15th with a Davidson County address, a No Mow Month yard sign will be delivered to your house at the end of March. More details will be provided after registration.
Will I be fined by Metro Codes if I let my grass grow tall?
No! The Compact is partnering with Metro Nashville on this project; as long as residents keep their grass below 12 inches in height and visibly display their No Mow Month signs in their yards, they will be in compliance with Metro’s High Grass and Weeds code.
Residents are encouraged to check HOA guidelines to ensure compliance with additional neighborhood regulations.
What do I do at the end of No Mow Month?
When it does come time to mow your grass at the end of April, be sure to have a weed eater handy for the first pass over. The grass may be too long for your mower to handle.
Your No Mow Month sign will be collected from your yard during the last week of April. Please place the sign in a visible location at the end of your yard for easy collection.
Do I have to let my whole lawn grow?
Nope! If you’re apprehensive about letting all of your grass get long, try starting with a small section of your yard– perhaps near a downspout, at the bottom of your driveway, or wherever a lot of rainwater tends to accumulate.
What if I am not a resident of Davidson County, but still want to participate?
You’re welcome to participate in this April’s No Mow Month event as a non-Davidson County resident! Signs are $10 for out-of-county participants, and you must come pick up your sign from Compact staff at a designated location in late March. Please complete the registration form to reserve your sign; more details will be provided after registration.
Registration for No Mow Month 2025 is now closed.
If you registered by March 15th, the Compact’s Field Team will deliver your No Mow Month sign directly to your house and pick it up from your yard when April is over. An email with details for No Mow Month sign pick up will be provided to those who registered after March 15th.
