New ryegrass with improved resistance to grey leaf spot, brown patch, & other diseases.
HAVEN turf-type perennial ryegrass is a newly released variety focused on providing improved disease resistant turfgrass, specifically in the areas of grey leaf spot, brown patch, and red thread. HAVEN is ideal for use on fairways, athletic fields, home lawns, high traffic areas, and other locations where additional disease resistant perennial ryegrass is needed. HAVEN has an attractive dark green color that balances well with today’s bluegrasses and tall fescues, making it an ideal candidate for blending as well pure stands. The following performance data demonstrates why you should make HAVEN your next perennial ryegrass:

Planting Instructions
For ideal turf, plant HAVEN on fertile, neutral pH soils during the cooler seasons of the year, such as spring and fall. If needing to plant during other times, plan on additional overseeding. For a thick, lush turf, the following seeding rates are recommended:
| New Planting | Overseeding | |
|---|---|---|
| Home Lawns | 5-8 | 7-10 |
| Athletic Fields | 9-15 | 12-18 |
| Greens | - | 25-35 |
| Tees | 9-15 | 12-18 |
| Fairways | 225-350* | 300-425* |
