If you plan to seed, establish, and manage ryegrass, you’ll need to plant, fertilize, and irrigate at the right times and in the proper proportions — and start with high-quality perennial ryegrass seed. The tall and thin tetraploid varieties have wider leaves and four sets of chromosomes. ); 90% of which are in the southeastern United States. Do not start in arid or excessively dry locations or conditions. No soil is perfect, especially the poor-draining, low quality sub-soils usually exposed by new construction. Temperatures above 100 degrees Fahrenheit commonly kill ryegrass, especially during a prolonged heatwave. Prepare the bed a few weeks before sowing, modifying the soil as needed, and adding moisture constantly. Ryegrass is naturally a diploid plant, meaning it has two sets of chromosomes. The ryegrass is hairless and has narrow, shiny green leaves. It is considered the best cool season perennial pasture grass in many areas. Ryegrass is also known for its quick germination period and is used extensively for establishing new lawns. This perennial cluster is mainly planted on pasture for grazing, silage and green cutting.
