Grasses with this type of growth habit do not readily recover from damage or fill-in bare areas on their own. Rhizomes are stems that grow horizontally underground. Stolons are horizontal stems that grow above the soil surface. Grasses with either of these types of growth habit can readily fill-in adjoining bare areas and also recover more readily when damaged. Kentucky bluegrass is by far the most popular species used in home lawns in northern Illinois, due to high quality appearance, hardiness, and recovery ability.
Kentucky bluegrass spreads by rhizomes.
Kentucky bluegrass prefers full sun, although a few cultivars have tolerance to light shade. Kentucky bluegrass is slow to establish by seed, and is also readily available as sod. Fine fescues require less maintenance and many adapt to shade. The fine fescues include red and chewings fescues, sheep fescue, and hard fescue. Maintenance levels are generally low, especially fertilizer needs, and fine fescues may decline in full sun when mowed frequently.
