Combat Extreme™ Northern Zone - Tall Fescue & Kentucky Bluegrass Seed

Combat Extreme™ Northern Zone

Combat Extreme™ Northern Zone - This tall fescue and Kentucky Bluegrass mix produces fine to medium leaf blades which allows a dense turf to form. This grass seed mix uses lower-growing cultivars which means that mowing requirements and clipping yields can be reduced up to 30 percent. Combat Extreme™ Northern Zone grass seed establishes rapidly when soil temperatures are above 55 degrees Fahrenheit. The varieties of turf type fescue grass were selected due to their ability to withstand hot summer temperatures as well as cold and harsh winters in USDA Zones 4 - 5. Combat Extreme™ Northern Zone grass seed has improved germination which allows it to establish more quickly than other varieties and its lower growth habit significantly reduces the amount of top growth. It does extremely well in full sun or partial shade in USDA Zones 4 - 5. Combat Extreme™ Northern Zone grass has the addition of Kentucky Bluegrass for extra cold tolerance and turf density. Combat Extreme™ Northern Zone grass seed an excellent choice for professional or home use.

Three Combat Blends To Optimize Varieties:

Each Combat Extreme mixture will perform well outside of the given zone. For example, there is no reason you could not use Combat Extremeâ„¢ Transition Zone in USDA Zone 8 or Combat Extremeâ„¢ Northern Zone in USDA 6. These USDA Zones are given as optimal guidelines, but not as fixed rules.Combat Extremeâ„¢ grass seed is one of the few tall fescue grass lawn seed blends available that is 100% weed free!

This lawn seed for cold weather mix consists of 90% turf type fescue and 10% Kentucky bluegrass by weight. By seed count, this is nearly a 50/50 blend. It will contain 2 out of the 5 turf type fescues listed below and Midnight Kentucky Bluegrass.

  • Chanelle Turf Type Fescue Grass
  • Roman Turf Type Tall Fescue Grass
  • Brute Turf Type Tall Fescue Grass
  • Barbarian Turf Type Tall Fescue Grass
  • Annihilator Turf Type Tall Fescue Grass
  • Midnight Kentucky Bluegrass
  • Blue Chip Kentucky Bluegrass
Seed size is much larger for turf fescue than Kentucky Bluegrass; therefore, by weight this is a 90%/10% fescue/bluegrass blend, but by seed count it is a pretty equal blend.

Unlike other turf type tall fescue grass seeds, Combat Extreme has the ability to repair itself. Traditional tall fescue grass will clump together, not filling in the bare spots and producing an uneven lawn. With bare spots, weeds are more apt to take over the lawn. What makes Combat Extreme™ Northern Zone grass seed unique is its ability to fill in these open areas with through aggressive tillering.

This is a new and improved, heat and disease resistant tall fescue variety developed for superior turf quality across a wide area of adaptation. Annihilator is a dark green, moderately fine textured variety that exhibits excellent wear tolerance, improved turf density and resistance to Brown Patch. It quickly forms a strong dense turf because of its rhizomatous root system. Annihilator is endophyte enhanced for added disease resistance.

Chanelle fescue grass is an exceptionally dark green tall fescue. Chanelle is a quick establishing grass with great drought tolerance and good winter hardiness. It will perform well with any top rate fescues in home lawns, park settings, sports fields, or anywhere a permanent high quality turf is desired. Chanelle works well in full sun in the North half of the U.S. or partial shade in the Southern half of the U.S.

These are rugged varieties that perform well in a wide variety of soil types and management regimes without sacrificing turf quality. They have excellent drought performance. Roman and Brute are durable for high traffic and have good shade and cold tolerance as well.

The quality level of these varieties sets a new milestone with finer leaf texture and increased shoot density yet not compromising the wear tolerance. There are no limits to the use of these varieties for mixtures for sports, amenity or extensive purposes - in the private sphere, public areas or for turf professionals!

Probably the most outstanding feature of Midnight Kentucky bluegrass is its unusually dark blue-green color giving it a rich color even under low maintenance conditions. Its high tiller density provides a thick carpet that will stand up to the abuses of athletic fields and high traffic. Sod producers and homeowners alike will enjoy Midnight's dwarf growth characteristics which result in fewer mowings and lower maintenance costs. This outstanding cultivar shows good resistance to leaf spot and stem rust, stripe smut and dollar spot. University trials have documented Midnight's heat and drought tolerance. Kentucky Bluegrass is recommended for use on athletic fields, golf courses, sod blends, parks, professional landscaped, and home lawns areas where Kentucky bluegrass is adapted. Midnight is one of the elite and top selling Kentucky Bluegrasses on the market today. Blue Chip is a Midnight type of Kentucky Bluegrass with the same characteristics.

Another great feature of Kentucky bluegrass is its extreme cold tolerance. That is why we have added it to our regular Combat Extreme blend for the USDA Zones 4-5 where cold tolerance can be of the utmost importance. Bluegrass blends well with turf type fescue and makes it softer in appearance and more dense. Midnight Kentucky bluegrass was also developed with quick establishment in mind. It is wear tolerant and repairs itself by rhizomes and tillering improving its turf density.
