Kentucky Bluegrass - Hybrid SPF-30
About...
SPF 30 Heat Tolerant Hybrid Bluegrass - Now Professional Turf managers can add genetic diversity with a high-performance cool season grass cross between Texas Bluegrass x Kentucky Bluegrass! Expanding the area of adaptation for bluegrasses, TX x KBG types have been successful farther south than traditional Kentucky bluegrasses, and are adding heat & drought tolerance and summer performance to northern zone turf. Can be used in full sun or partial shade in USDA zones 4 - 10.

SPF 30 Heat Tolerant Hybrid Bluegrass - Now Professional Turf managers can add genetic diversity with a high-performance Texas Bluegrass x Kentucky Bluegrass cross! Expanding the area of adaptation for bluegrasses, TX x KBG types have been successful farther south than traditional Kentucky bluegrasses, and are adding heat tolerance and summer performance to northern zone turf. SPF 30 produces a high percentage of living ground cover throughout the summer, recovers quickly from drought, and is resistant to brown patch. With its aggressive rhizomes, SPF 30 improves the ability of tall fescue turf to recover when combined in a mixture. SPF 30 is an elite and medium-bladed bluegrass for landscape contractors, sports turf managers, and golf course superintendents who are battling the stress of summer heat. SPF 30 (HB 128) is a sister to HB 129 TX x KBG.
Use SPF 30 hybrid bluegrass in Sod, Sports, Golf Roughs and Lawns, Use SPF 30 in blends with other bluegrasses, with perennial ryegrass, and in multi-species mixes at the rate of 10%-35% by weight to increase density, durability, and genetic diversity. Added to turf type tall fescue at the rate of 5-15%, SPF-30 will increase density, provide brown patch performance, and aid in drought stress recovery. SPF-30 has also demonstrated persistence in partial shade areas in warm-season regions where low light condition are not suitable for Bermudagrass.
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. SPF 30 has shown increased tolerance to many diseases compared to regular Kentucky bluegrass including Rhizoctonia blight.
Not only does SPF 30 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.
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.
SPF 30 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

The varieties that are selected for this blend are chosen for their excellent color, quick establishment, resistance to disease, and their ability to perform under a broad range of weather and soil conditions. Kentucky Blue Grass lawns are known for their fine to medium texture, uniformity of color, and density and durability for traffic. Kentucky Bluegrass has the ability to repair with rhizomes that spread and fill thin, worn areas. Because of this, KGB is excellent for the backyard lawn where children and pets play or on the ballpark field. Kentucky Bluegrass lawn seed typically emerges in 14 - 21 days. First mowing is typically three weeks after emergence.

True Putt is an excellent new perennial bluegrass that is medium green depending on fertility and forms a uniform, dense turf at greens height. This creeping bluegrass is medium to fine textured and forms an extremely dense putting green grass surface. True Putt helps crowd out Poa annua better than creeping bentgrass. This Bluegrass seed germinates rapidly in 5 to 7 days under optimum conditions especially when kept continually moist. It is very vigorous and mixes well with creeping bent grass in a 50/50 mixture. True Putt is a great grass seed choice for the home golf green.
True-putt is drought and shade tolerant and recovers well after water stress events. Tolerates close mowing to 1/8 inch (optimum mowing height on greens is 5/32), but will also perform well at 1/2 inch mowing height. Creeping bluegrass is a deep rooted grass which has exhibited some field resistance to pink snowmold. This putting green grass is well adapted to the cool, moist climate especially in the northern half of the United States.
True-Putt will soon be one of the leading putting green grass varieties on the market. A creeping bluegrass putting green has excellent density, shade tolerance, heat tolerance, wear tolerance, and cold tolerance. True Putt golf grass establishes quickly from grass seed, and it produces a thick turf competing with the grassy weed Poa annua. For those of you who want to build your own putting green, True Putt is a great choice for putting green seed.
