After your lawn is established, fertilize each year when the grass is actively growing using 4 to 6 pounds of nitrogen fertilizer per 1, square feet of grass. The active growing time for the grass depends on your location and climate. In California, for example, the active growing time ranges from late February to late May and again in October and November.
Kentucky bluegrass is susceptible to pests, disease and weed problems. Some weeds that may infest your grass include crabgrass, clover and dandelions.
Common pests include white grubs and sod webworms. Apply insecticide if you notice any signs of insect damage. Diseases that may affect your grass, especially if the grass is not properly cared for, include leaf spot diseases and powdery mildew.

During the active growth period, Kentucky bluegrass will thrive with fertilizer that has anywhere from four to six pounds of nitrogen per 1, square feet. Apply organic matter such as rotted manure or compost tilled to eight to ten inches to improve soil structure and fertility. Different types of grasses thrive at various heights. Kentucky bluegrass, for example, works best when mowed to a height of one-and-a-half to two-and-a-half inches.
Set your first few mowings at a lower setting with a sharpened blade. This allows sun, water, and nutrients to continue penetrating the base of your grass and stops the tips from turning dull and brown.
From there, raise your mower height every one to two weeks until it hits about two-and-a-half to three inches. This added height will protect the root system from the sun. In case you experience a hot or dry summer, this will also help retain moisture.
