Kentucky Bluegrass

Poa pratensis

Plant Details:

Plant Type: Lawn & Blends
Plant Family: Poaceae
Plant Description: Cool-season turf-grass with attractive blue-green foliage. Most popular turfgrass in Utah. Grows best when temperatures are cool but will struggle during the summer. Requires a significant amount of water to remain green during the summer but will be healthier if watering is applied at the proper amounts. Proper irrigation typically involves decreasing irrigation frequency while increasing system run-time.
Plant Care: Mow regularly so that not more than 1/3rd of the leaf is removed each time. Most grasses, especially bluegrass and fescues, should be mowed at a height of 2 ½ to 3 inches to provide for healthy root growth and to help compete with weeds. Provide adequate water, but avoid overwatering. Fertilize 1 to 2 times per year. Fall is the most effective time to fertilize whereas spring can be optional. Aerate once a year, especially in compacted soils. If aerating, ensure aerator tines are clean. Dethatching is not necessary except on highly maintained areas such as sports fields and golf courses. Most weeds can be controlled through maintaining a healthy and competitive lawn. Otherwise, use appropriate weed control methods including hand pulling and appropriate herbicide use.
