How low to mow your lawn in the fall really depends on what type of grass you have! Here’s a definitive guide to the optimal fall lawn length for your final cut this season!

Before You Mow Low, Remember This!

Not too short: The blades of grass act as a shield protecting its roots from inclement weather. Cutting a lawn too short will expose the roots to the harsh cold, throwing your lawn into shock. This means your dormant lawn may not come back in full swing and instead spend the spring recovering.

Not too tall: Leaving grass too long going into winter will result in a tangly, matted lawn. This is the perfect breeding ground for unwelcome bacteria and fungus to grow. Bacteria = lawn disease and lawn disease will quickly take your fab grass, to drab grass!

Just right: Regardless of the grass you have, when it comes to fall lawn length, you want to shoot for mid-length grass. The best way to protect your lawn going into winter is to find a balance!
