Thermal Blue Heat Tolerant Hybrid Bluegrass - Kentucky bluegrass is a lush, green grass everybody wants in the lawn. Trouble is, it can not survive hot, dry conditions. Scotts has developed an exclusive grass called Thermal Blue Kentucky Bluegrass that can survive heat and drought and spreads like ordinary Kentucky bluegrass. It can survive wherever tall fescue grows.
Hybrid bluegrasses germinate from seed slightly faster than Kentucky bluegrass, but the differences in overall establishment rate have not been significant. Hybrid bluegrass germinates and establishes slower than tall fescue. Hybrid bluegrass survive prolonged heat and drought periods. Another noteworthy feature is the disease tolerance of hybrid bluegrass. Thermal Blue has shown increased tolerance to many diseases compared to regular Kentucky bluegrass including Rhizoctonia blight.
Not only does Thermal Blue stand up to moderate summer temperatures extremely well, it shows outstanding shade hardiness. Hybrid bluegrasses possess a strong creeping growth habit due to rhizomes (underground stems). This creeping growth potential is something that most tall fescues do not possess. This should further improve turf density and provide for recuperative potential if a turf stand is damaged. Thermal Blue, featured in New Heat-Tolerant Blue also outperformed tall fescue when exposed to other summer challenges, including growing well in the shade and a higher resistance to brown patch. Other university studies, from Ohio State University to Kansas State University, had similar results in tests showing Thermal Blue's ability to germinate, withstand heat and disease and establish a thick root system.
With the combination of heat and drought tolerance, shade tolerance, quick establishment, and excellent disease resistance, this grass is one of the best on the market.
Thermal Blue Grass Characteristics:
- Increased shade tolerance
- Increased wear tolerance
- Allows sod to self-repair
- Competitive nature reduces clumping and broadening of leaf blade width that occurs in other grasses with age
- Ideal partner in mixes with turf type fescue
- Aggressive growth habit
- Optimum mowing height of 2 - 5 inches
Seeding Rate & Planting Time
- New turf: 2 - 3 pounds per 1,000 square feet or 80 -120 lbs per acre
- Overseeding: 1 - 1 1/2 pounds per 1,000 square feet or 40 - 60 lbs per acre for broadcast overseeding
- Plant when soil temperature reaches 55 degrees in spring up until a minimum of 8 weeks before frost in fall
