Denver is a city on the plains east of the Rocky Mountains in Colorado. The city averages about 5,280 feet in elevation. Denver gets good sun most of the year. Because of the area's climate and elevation, some years it can be difficult to ensure that your lawn gets adequate water for optimum health. A healthy lawn can resist most problems better than a lawn that is stressed.

Water

Denver is a semi-arid area that gets rain in the spring, with more arid periods in the summer and fall. In the spring, rain is usually adequate for most lawns. However, as summer arrives, providing your lawn with an inch or two of water early in the morning every day or two can prevent its natural browning. In years when there isn't enough rainfall, Denver and surrounding cities and counties may implement watering restrictions. Violating those restrictions can result in fines. Restrictions can range from prohibition of watering during the heat of the day to a complete ban on lawn watering.

Weeds

The Denver area has problems with broadleaf weeds like dandelions and clover. Proper mowing and watering can keep your lawn thick, making it more difficult for the weeds to take hold. What constitutes proper mowing and watering depends on the type of grass in your lawn and the amount of natural rainfall. In general, however, cutting your lawn to between 1 1/2 and 3 inches tall and giving it an inch or two of water two or three times a week will help keep it healthy. Once the weeds are in the lawn, an herbicide followed by feeding and seeding can help to reduce their number. Liquid spot treatments that target only the weeds usually work better than an overall application, according to Colorado State University. The university says the most common herbicide for controlling broadleaf weeds is 2,4-D, or 2,4-D combined with other chemicals.

Diseases

Lawn diseases in the Denver area are all fungal problems, according to Colorado State University. Soil in Denver is often heavy clay. That soil tends to quickly become saturated and retain a lot of surface moisture. Common fungal problems in the Denver metro area include ascochyta leaf blight, which affects the tips of grasses in dry areas such as near sidewalks; leaf spot, which is indicated by elliptical spots tinged in purple, and dollar spots. Dollar spots are dead areas about the size of silver dollars in your lawn. Powdery mildew can also affect grass in shaded areas. The best way to avoid problems like these is to properly maintain your lawn, including watering in the morning so that excess water evaporates in late morning and afternoon sun.
