RPR Regenerating Perennial Ryegrass

RPR (Regenerating Perennial Ryegrass)

RPR is the first commercially available creeping perennial ryegrass that is so revolutionary that it is placed in a category by itself. Being the winner of the 2011 STMA (Sports Turf Managers Association) Innovative Award, and used at professional sporting complexes nationwide, it is an excellent choice for lawns and sports fields looking to establish a cool season stand.

Seeding Rate

RPR is seeded at a rate of 300 lbs per acre or 7 lbs per 1000 SQ FT. RPR can be seeded as an individual variety or mixed with various cool season grasses, like fescues or annual ryegrasses, as well.

Planting & Soil Preparation

Prepare a smooth firm seedbed free of weeds, sticks and large clods. Plant at 1/4 of an inch deep, or broadcast and pack or lightly rake seed in. The soil should be kept moist but not to the point of standing water. Under ideal conditions, germination should take place within 7-14 days.


Perennial ryegrass takes relatively little fertilizer compared to grasses like bermudagrass. Fertilizer applications should be made starting in February at a rate of 1/2 to 3/4 lbs of actual nitrogen per 1000 SQ FT. Fertilizer applications can be made monthly through the month of May.


Mowing heights can vary on perennial ryegrass depending on the type of activities that may occur on the grass. In most instances, perennial ryegrass looks its best when kept mowed at a height of 1 1/2 inches. If a tighter, more dense turf is desired you can mow the grass down to height as low as 1/2".
