My grass was perfect two weeks ago--thick and green with a few weeds. All of a sudden it has random yellow dried out spots that are semi-circular in the front and back. I haven't done anything different to the grass--same watering schedule. What is wrong with it? It is insects under the grass like grubs or something?

There are plenty of conditions that can lead to yellow lawn patches. Here are the top five causes:
Drought - Lawns need water, or they lose their green. If you have sandy soil, which drains like a sieve, your lawn may require more water than you think. The best lawn care bet for this is a nice deep watering in the early morning, once or twice a week.

Nutrient Deficiency - Lawns lacking in nutrients will develop a sickly yellow look. If you haven't fed your lawn in a while, you should suspect this culprit. The lawn care solution is a bag of fertilizer.

Chemical Burn - If you misapply fertilizer, insecticide, or any other chemical to your lawn, you can end up burning it. Preventative measures, like following the instructions exactly, are critical, but once the damage is done, the best lawn care answer is watering and waiting.

Animal Damage - Your dog, your neighbor's dog, a pesky rabbit that crawls through the fence--any number of animals can leave urine burns on your lawn. If keeping animals off your lawn is not possible, watering in urine before it can burn or flushing existing burn circles is the best lawn care action.

Lawn Disease - Lawn fungus can lead to yellow spots in your lawn. If nothing else seems to explain your lawn's yellowing, you should be suspicious of this cause. For a sure diagnosis, take a sample to your local extension office.

Once you discover your lawn care problem, you can get cracking on a lawn care solution.
