If anyone wants to go an organic route on their lawn I have been having amazing success with the following products. I'm using this in my 5000 sqft fenced in area for my small dog.
Purely Organics for lawn fertilizer. Available at Home Depot. I believe its made from recycled grain from a brewery. Works similar to Milorganite with the soil and you can't burn your lawn with it. I use 3 bags a year.
$31.97 for 25lb bag that does 5000 sqft.

I don't use much of any herbicides. A healthy established lawn doesn't really need any. I will walk around and spot treat with a sprayer using some Tenacity which is semi organic made from Mesotrione derived from the bottle brush plant.

I also use this organic one that is just Iron HEDTA.

For ticks and insects I spray wondercide every 30 days. Its just cedarwood oil. I also have had amazing success putting their cedarwood oil on my dog for ticks.

For grubs I drop a bag of Grub Gone. Its active ingredient is Bt, a naturally-occurring soil bacterium
