Carpetgrass is a low-maintenance grass requiring little fertilization that thrives in subprime growing conditions. However, regular mowing is necessary to avoid the growth of unsightly seed stalks, and you may have to water it frequently to prevent drying out the soil. That includes watering the grass over dry winters to help keep it healthy, and it may start dying out in particularly cold climates where it grows poorly. Carpetgrass can also be vulnerable to some types of turf fungus, so it’s important not to overthatch. 

Water your yard a little more deeply after a drought for about two weeks (while still avoiding overwatering). Continue to water in the early morning hours before 10 a.m. You'll also want to invest in some high-quality fertilizer to get more nutrients to your roots and help them grow back stronger and quicker. Look up your grass and soil type, or do a soil test, to see what type of fertilizer you need.

Technically, yes—and you may have some successful growth—but this isn’t the ideal way to fill in sparse areas. By clearing leaves and debris, amending the soil, and aerating it properly before you lay the seeds, you’re providing the most ideal conditions for them to germinate.

You can try that, but it isn't likely to yield results. It's like watering potted plants without putting the seeds in. Most of the tossed grass seeds sit on top of the soil or existing grass blades and never germinate. The seeds need to make it into the soil, just like growing a potted plant. The best way to accomplish this is to aerate your lawn first, then overseed.
