Very similar to and adapted to the same conditions as Kentucky Bluegrass, but is more tolerant of shade and wet soils. It has a shallow root system. Excellent in seed mixtures for lawns in shady areas where soil moisture is adequate. Does not tolerate drought. Poor wearability when seeded alone.
Seeding rate 3 to 5 lbs/1000 sq.ft.
Rough bluegrass is capable of forming a reasonable turf under certain limited environmental conditions and careful management. It is fine-textured turfgrass developing a high shoot density under cool, moist conditions. It is capable of withstanding a considerable amount of shade if sufficient moisture is present. It is one of the most winter hardy turfgrasses with very good low temperature tolerance. The major weaknesses of rough bluegrass include poor wear, drought and high temperature tolerance. It is sometimes included in a seed mixture with Kentucky bluegrass because of its shade tolerance. However, due to its tendency to produce bright yellow-green patches, it does not blend well with Kentucky bluegrass . It responds vigorously to fertilizer and irrigation, and under conditions where water is supplied too frequently, it becomes intolerably aggressive and smothers out the Kentucky bluegrass. During July and August patches of rough bluegrass wilt and brown-out markedly unless careful attention is paid to its water requirements.
University research has shown that using a blend of different varieties of Poa trivialis can benefit the superintendent and golf manager in a number of ways. Three different, unrelated varieties increases the genetic diversity on the turf surface, allowing for better ability to withstand any unexpected stress or pest organism. Germination results and seedling vigor will be enhanced when planting different varieties together. University research, as well as trials by Seed Research of Oregon’s Director of Research, have shown that mixtures of Poa trivialis germinate better and faster, resulting in higher density and turf ratings once established.
