Thermal Blue is a hybridized bluegrass that combines the turf quality characteristics of Kentucky bluegrass and the drought tolerance of Texas bluegrass. The strong spreading rhizomatous nature of this grass provides accelerated recovery from extreme heat and drought situations. Rhizomes originate from the crown of the plant, the central growing point, and spread laterally underground. From rhizomes, new plants are produced that fill in bare spots and form a thick knitted sod. Thermal Blue is also characterized by an extensive root system that performs better in high heat than traditional Kentucky bluegrass. Similar to Kentucky bluegrass, Thermal Blue will enter dormancy during extended periods of drought.
Growing traits of Thermal Blue include a fine leaf texture characterized by a pleasant deep green color. Thermal blue grows well in a wide range of soil types. The heat and cold tolerance is also excellent. Adaptable to a wide range of climatic regions, Thermal Blue performs well from northern climates to the southern transitional zone. From full sun to moderate shade, Thermal Blue is a uniquely adaptable grass that produces high quality turf.
Maintenance of Thermal Blue is similar to Kentucky bluegrass. Fertilizer applied at 4 to 5 lbs of nitrogen per year will produce a high quality lawn. At reduced fertility, Thermal Blue maintains acceptable turf quality. Fertilization should be applied primarily in the spring and fall to encourage extensive root growth in preparation for summer stress periods.
