My lawn has bare spots and areas where grass is very thin. I don't want to do a total lawn renovation. Can I just rake lawn real good and apply some grass seed and then a light top dressing? I could not find a Bulletin or fact sheet for this. Also, any recommendations on grass seed?

If you want to convert to a different type of lawn, have an overabundance of weeds, or need to amend the soil due to poor soil quality, construction or compaction, then a complete renovation would be best. Otherwise, overseeding an existing lawn is good for bare spots and turfgrass that is showing signs of thinning.
Thoroughly core aerate the lawn, ensuring holes are 2" apart. Overseed the lawn after aerating. See the section of CSU Fact Sheet 7.241 on types of seed and what can and cannot be overseeded into your existing lawn species. After seeding, follow the recommendations on caring for the new seed. Provide frequent, light watering to keep the seed moist, but not saturated. Below is the link to CSU Fact Sheet 7.241 on lawn renovation. Since you are doing only a partial renovation, skip steps 1-4.
