Something like a 15-0-15, 16-0-8, close to that - little or no phosphorus. Applied at 1/2 lb of nitrogen per 1000 sq ft.

Where you located - just to help you source it.

You plan on fertilizing it now? Getting a little late in the year to fertilize centipede - if your lawn looks good, I might suggest you hold off until next spring.

Mandeville

I only fertilized once in early spring and did so with straight nitrogen (dumb) and have some areas that took a beating (brown) from the summer heat. That area probably also needs to be aerated because too hard and will probably put some seed down. Thinking I need to get started and not sure of the best order but hoping we are about done with above 90 degree temps. Looks that way for next 10 days or so

Mandeville - you have Site One Landscape Supply (only 2 in the state) - their pricing is very good and it’s where I buy fertilizer and lawn chemicals. I’d suggest LESCO 15-0-15, 15-5-15, or maybe 18-0-18, if they have one of those 3 in stock. If using the 15–x-x or 18-x-x apply 3 lbs per 1000 sq ft but try to do it ASAP.

Usually end of July is the recommended cut off for centipede fertilization as it goes dormant sooner than the other warm season lawn grasses.

I wouldn’t recommend putting out centipede seed this late in the year. Aerating the hard areas - of course do that.

Good to know. I was about buy and lay down another round of fertilizer for my centipede lawn.

I use one of the local companies for fertilizing, herbicides etc. They came out 3 or 4 weeks ago to put out some herbicide. About 3 acres total. My backyard and half of my front yard is all centipede that I sodded 6-12 months ago. The other half of my front is a mix of weeds, st Aug, Bermuda, carpet grass, etc. after this last treatment the centipede is fine but a lot of the rest has a lot of browning. Looks like the grass is stunted. Any clue what happened? They want to fertilize next week to try to get it back going. Good idea or no?

This picture is a small sample of what I’m referring to.

5-0-31. Do it now. I’ve run that until late September and no trouble

I’d start by asking you if they provided with you a work sheet of what herbicide they applied and at what rate? Of course, trying to assess if they used a herbicide at an application rate that wasn’t compatible with the other non-centipede grasses.

Yes when I stated earlier that the cut off date for centipede fertilization is usually by the end of July that applies to higher nitrogenous fertilizers that accelerate grass growth.

The 5-0-31 low nitrogen, high potassium fertilizer is a winterizer fertilizer designed to strengthen and harden off turf grasses for the upcoming winter and certainly acceptable and often recommended, and it can be applied in August/September.

Winterizer fertilizers are applied in early fall when the grass is still in active growth but well before the turf becomes dormant.

No they didn’t, my fault for not requesting. I’m going to find out Monday.
