What kind of grass is in my lawn? | Olympia & DuPont Lawn Care Company
Most of the lawns in our area start out as a 3-way blend of Perennial ryegrass (Lolium perenne L.) (PRG). Perennial ryegrass is a cool season grass that thrives in our moist and cool climate. PRG has a rapid germination rate and vigorous seedling growth. It prefers full sun but will tolerate some shade. It grows best in non-compacted, well drained soil. The fine leaf texture, dark green color and excellent wear tolerance makes for a beautiful lawn.
Over time Annual bluegrass (Poa annua L.) (Poa) starts to establish. Poa is a cool season grass that is adaptable to moist, cool and shaded areas. It can grow in all soil textures including compacted soil. Poa has a fine leaf texture, lighter green color with shallow root depth resulting in poor wear tolerance. Poa withstands close and frequent mowing and is able to produce seed heads even at 1/8” mowing heights. Individual plants can produce between 1,000 and 2,500 seeds in a season.
Here are some things you can do to encourage Perennial ryegrass and discourage Poa annua encroachment:
-Aerate, De-thatch, Lime and Over-seed with 3-way Perennial ryegrass in the Spring or Fall to relieve compaction and increase turf density.
-Irrigate deep and infrequent to encourage root development in PRG. Overwatering in shady areas encourages Poa.
-Avoid mowing too low or scalping the lawn. Poa can tolerate low mowing heights.
-Remove clippings when Poa is producing seed heads.
