Kentucky Bluegrass

Kentucky bluegrass is a cool-season grass that grows best during the fall, winter, and spring months when temperatures are cool. Its growth slows during the warm summer months. Kentucky bluegrass prefers full sun, but will tolerate some shade. This species is used widely throughout the U.S. where it is well adapted, but it has a poor summer performance in areas with warm to hot temperatures. When stressed by temperatures, lack of water, or poor soils, Kentucky bluegrass can be susceptible to disease and weed invasion. It can tolerate cold winters, but has a relatively low tolerance for heat and is only moderately drought tolerant. During the summer months, if stressed for water, Kentucky bluegrass can go dormant. It has moderate wear tolerance, recovering quickly from some abuse.

Kentucky bluegrass provides a dark-green, medium-textured turf. Grass color ranges from bright green to deep bluish green. This species spreads by underground rhizomes that can self-repair injured, worn, or damaged spots. Kentucky bluegrass produces a dense turf. It is moderate to high maintenance and makes beautiful home and sports grasses.

Aggressive Type

This group is recognized for its aggressive lateral growth habit and development of a turf with very high shoot density. Examples are Limousine, Julius, P-104 and Touchdown.

America Type

Within the Compact Type a number of varieties exhibit growth and performance similar to America.These varieties have fine leaf texture and higher tiller density than other compact type varieties. America types in contrast to Midnight compact types have good resistance to powder mildew.

Bellevue Type

Turf with medium to low growth, medium to wide leaves and medium density. Excellent cool-season vigor exists in this group, which is evident by excellent color retention and turf quality during winter and early spring green-up.This group has good recovery to summer stress, good resistance to stripe smut disease but is highly susceptible to bill bug damage.

BVMG Type

Baron,Victa, Merit, Gnome types:This group has high seed yield potential and generally produces medium to good quality turf in the absence of stripe smut.The BVMG types generally are very stemmy in early spring.This group also has poor winter color, long winter dormancy and suffers from significant billbug damage.

CELA Type

Challenger, Eclipse, Liberty,Adelphi Cheri Type They will produce a turf of medium-low growth and medium density with medium wide leaves.These cultivars have moderate resistance to stripe smut and are moderately
susceptible to dollar spot. Seed yield potential of these cultivars is relatively high.

Common Type

Generally erect growing types with narrow leaf blades.All common types are susceptible to leaf spot disease and may be extensively damaged by this disease during the cool, humid conditions of winter and spring.

Compact Type

Low compact growth and good leaf spot resistance.This group has long winter dormancy (except P-105) and good stripe smut resistance. Examples are Diva, Moonlight, P-105, Blackstone,Apex, Glade,Alpine. Julia Type These cultivars form a high quality turf, but have moderate winter performance.They also exhibit good resistance to leaf spot but can be damaged significantly by brown patch.

Mid-Atlantic Type

This group forms vigorous turf of medium density with deep, extensive root and rhizome system.This group has moderate susceptibility to leaf spot, but has excellent ability to recover from leaf spot and other stress due to the deep extensive rhizomes system.This group has great tolerance to heat and summer stress. Examples: Eagleton, Preakness, and Livingston.

Midnight Type

Within the Compact Type family, this group has very long winter dormancy, late spring greenup, very dark green turf color, good heat tolerance, but are susceptible to powdery mildew. Examples are Ginney,Alexa, Midnight, NuGlade, Quantum Leap,Total Eclipse,Award and others.

Shamrock Type

Similar to the BVMG types with high seed yield potential, but unlike the BVMG types, Shamrock types exhibit good resistance to stripe smut. Examples, Guinness, Champagne, Brooklawn.
