13-13-13 isn't for your lawn, you'll feed the weeds more than anything. Not saying you won't/can't achieve a beautiful lawn by using it, but you stand a risk of some serious weed issues if your yard goes under stress, such as a drought, cutting the yard too short etc.

a weed and feed combination isn't good either

Centipede requires a high nitrogen fertilizer but getting above 20 is considered high. I would stay around a fertilier with a rating of 16-4-8 as this is all the lawn needs. Avoid buying at box stores too, as they will not carry a fertilizer like this, normally. Sure, they will carry a grade that is high in nitrogen but all you are doing is giving your lawn a short high boost of energy. It will green up like it's on steroids but it isn't healthy in the long run. Reason being, grass can get addicted to this grade of eating habit and will have a weak immune system if you will. Any lack of water, change in weather or whatever, and your yard will suffer. Best to stay with something in the range I indicated. Anything above this you are only killing my beloved fish. The overage of nitrogen goes into the estuaries and causes something to the effect of being called algae blossom, not good.

Pre-spring, spread a weed pre-emergent killer to baiscally keep the weeds from ever seeding out. Water your lawn with one inch of water a week and try avoid watering every day. Water once a week, as mentioned, at least once inch worth in growing season. Let your centipede grow high, like to the tune of 4" high. Takes some getting used to but once done for a while it will become thicker and much more beautiful. The shade provided by the grass blades will subside weed growth as well.

this isn't a very good pic of my grass, but it shows enough, I think. This lawn was planted in January, from seed, using a blend of rye grass (to hold my other seeds), bermuda (to hold my centipede seed) then centipede. Year or so later, the entire yard is covered and thriving

find one of these local to you and use them
