Yes, you can DIY either core or liquid aeration for your lawn. You can use a manual core aerator or rent an automatic one. Just be sure to mark off yard obstacles like sprinkler heads before you start. Liquid aeration is easier—just hook up a garden pump sprayer, although some are able to be attached to a hose. While liquid aeration is not as laborious as core aeration, you will need to focus on an even distribution of the solution across your entire lawn for it to be effective. Of course, if you are unsure about doing both, call a pro.

Whether or not grass will fill in bare spots itself depends on the type of grass you have. For example, grass with rhizomes (e.g., Bermuda grass) and stolons (e.g., Saint Augustine grass) will naturally fill in bald spots as it spreads laterally. However, clump-forming grasses will not spread. 

It’s best to fix lawn depressions during late spring. You want to wait until after your last frost date and when the yard is not too wet. This also allows ample time for new grass growth once you reseed.

Start your search for a good lawn care company by finding some landscapers in your area; it might be a good idea to research companies that already work on your block, as they’re more likely to be able to fit you into their schedules, given your proximity. Next, conduct a search online to see if they have positive customer reviews, and try to avoid companies that have poor scores or a history of complaints with the Better Business Bureau. Finally, make sure to ask each company about pricing, contracts, scheduling, and any add-on services.
