You can get a cheap test for your soil to see if you need lime or take a sample to a county extension office. Get an organic fertilizer which releases nutrients over time as opposed to most chem types. (also causes less salt build up in the soil than the chem types ) Spread it as directed (usually spring and fall.) Get a bag of milky spore and spread it two years in a row for grubs (could be why you have bare spots). You also might try nematodes this season as they will immediately kill this years grubs. You might get 2 or 3 years where you don't have to do anything for grubs after you get those things established. Keep the grass about 3" long to out compete the weeds. If the bare spots are pretty big, you might till them and add a layer of compost and re-seed. Do these things and you will have a nice healthy lawn that is safe for you, pets, kids and anything else that goes in it. One of the main problems in our waterways and estuaries is lawn chemicals, so if you can live with a nice yard that has some clover and stuff mixed with the grass it is worth it. Also, if you have enough compost, you can spread a thin layer over the grass and not need any other fertilizer. Less fertilizers = more fluke
