Frost And Golf Courses Don’t Mix

Los Alamos Golf Course staff would like to inform our Community about the importance of staying off frosted grass. 

Frost is nothing more than frozen dew that crystallizes on the grass. Being composed of 90% water, a grass blade freezes very easily, thereby making the normally pliable grass rigid and inflexible. Once frozen, the simple act of walking on a frosted course will cause the grass to 

break and rupture cell walls. The problem lies in that once the membrane is ruptured; future re growth of the grass blade is significantly hindered. Golf course grass, mowed shortest on fairways and greens, are therefore less robust than longer patches and are naturally most susceptible to breakage. 

When frosted grass is walked, jogged, or driven on, immediate damage is not seen until about 48-72 hours after the damage has occurred, causing the grass to turn brown and die. The destruction of the grass, especially on the putting surface, opens the door for the growth of weeds and disease, thus compounding the issue and further devolving the overall condition of the course. 

As the community enjoys the golf course area, whether playing golf, jogging, walking their dog, etc., please be aware of frost on the golf course. When the grass is frosted, please remain on the cart paths that connect throughout the entire golf course. The most common months for frost delay are October through March. 

Los Alamos County Golf Course Staff enjoy managing this beautiful space for the Los Alamos community and appreciate each of you helping in our efforts to maintain healthy grass and a quality experience for all.
