While Linn Perennial Ryegrass has been used to winterseed dormant southern turf, it is most often found in the north where the production of turf of exceedingly high quality is not a requirement. For decades the annuals have been used to winterseed greens, fairways, tees and roughs in the southern United States. Seeding Rates Seeding rates will vary according to specific needs, density desired and personal experience and preference. In general, the following seeding rates are recommended for the various golf course greenways. An annual application of 35 lbs. of nitrogen per 1,000 square feet is recommended for all of the ryegrasses.
Application is usually most effective when applied in equal parts in the spring and fall.
In some regions an application of phosphorus and potash may be desirable to maintain quality. A soil pH of 6.5 is ideal for ryegrass, but it will also perform in a range of 5.5 to 8.5.
