Perennial Ryegrass

Also read: Gray Leaf Spot

Common perennial ryegrass usually only lasts one season. Germinates quickly and can be used as a temporary ground cover while the slower growing bluegrass plants take hold.

The ryegrasses are best adapted to moist, cool environments where temperatures are not extreme in the winter or summer. In the United States, the northeastern and northwestern states are well suited to ryegrass. In the transition zone, perennial ryegrass may provide a permanent turfgrass. But in the southern states, both species serve as cool season annuals.

Of all turfgrasses used in the South, ryegrass probably has the highest maintenance requirement.

Perennial Ryegrass SeedheadMowing, watering, fertilization and pest management needs of ryegrass are higher than for any southern turfgrass. Ryegrass has a rapid growth rate in the spring and requires twice weekly mowing at the taller heights - above 1"; mowing at 2 3 day intervals at heights around 1" and daily mowing at heights below an 1".

Ryegrass is the least drought tolerant of the southern turfgrasses and needs frequent watering in the spring and early summer. In many golf course situations, daily watering is not unusual on ryegrass greens and fairways. Even on lawns, ryegrass is the first grass to show symptoms of drought stress.
