Kentucky bluegrass is mainly used for pasture grazing and it makes a great lawngrass and grass for waterways. Hay use is limited. It is highly nutritious and is grazed by most livestock and wildlife. It can tolorate close frequent grazing better than most grasses. By grazing it to a height of 1-2" you will favor productivity and allow it to maintain a dense sod. It will survive under low fertility, but is not highly productive unless well fertilized and grown with a legume.

Kentucky bluegrass has six major pests. The grub, bluegrass billbug, sod worms, chinch bugs, friut fly, and the greenbug aphid can be serious pests and will reduce production or even injure stands.
