In general, lawn problems are not a threat to residential lawns located in Colorado. Occasionally, an outbreak may occur after a long period of heat and humidity, but you can expect your lawn to remain relatively disease-free for the most part, as long as it is properly maintained. Sports fields and golf courses on the other hand are more susceptible to lawn diseases, because they are used and conditioned extensively.
However, there are some common problems in lawn care for the Colorado climate.
The lawn, like any other perennial, goes through certain phases of vegetation. In winter, the aerial part dies, resisting only through the roots, from where new growths appear in spring. But what do you do when the blanket of dead vegetation does not allow the appearance of new grass blades?
The first work that is required immediately after the temperatures exceed 15 degrees Celsius and the vegetation develops, is the scarification. Attention: this operation is performed only twice a year – spring and autumn – and allows some superficial aeration and soil decompaction. If the vegetation is high enough, the lawn can be mowed to favor its thickening.
After these operations, it is necessary to fertilize the lawn (using a granular fertilizer with prolonged release and rich in nitrogen or an organic chicken manure fertilizer locally produced).
Irrigation from now on is mandatory, once a day (preferably early in the morning), by using moderate amounts of water. If the ground is very compacted, it is necessary to aerate it once a year.
