I haven’t bought my supply yet this year, may stop tomorrow, but price for last purchase was about $30 for a 50 lb bag (24-2-11) - excellent price per pound.

You in Texas or LA? Seems fine to me, maybe a little high in phosphorus (P) but it seems to be what Texas A&M recommends? Are Texas soils often low in Phosphorus?

Anyway recommendations by the LSU AgCenter for St Aug and Bermudagrass base lawn fertilizer recommendation on nitrogen N, using 1 pound of N per 1000 sq ft, (1/2 pound per 1000 sq ft per application for centipede and Zoysia) and that equates to 6.6 lbs of 15-5-10 per 1000 sq ft (100 divided 15 = 6.6). I can’t read the label on that bag in regards to what they say should be applied per 1000 sq ft. I see that fertilizer does provide supplemental iron.

Anyway, I don’t see any reason why it wouldn’t be good. I’ve used LESCO 15-5-15 on centipede, but have now switched to LESCO 24-2-11 but my lawn soil is not deficient in P (middle number). Excess P over time more than required can sequester iron which helps to provide your lawn with that nice deep, green color.

Would be a good idea to have your lawn soil tested for soil fertility to see if your lawn needs a P supplement, and if not, going forward you should consider lawn fertilizer with a lower amount of P than the 5% contained in that product.

Phosphorus is low in North Dallas. Not sure about the Houston area though.

What about Lafayette with St Aug? Would I be wise to go with the 15-5-10 or or do I not need the phosporus and can go with Scotts Southern Lawn Food (32-0-10)

15-5-10 isn't a bad mix. 32-0-10 is a strong mix for St Aug. 32% nitrogen is high. The amount you put out can be adjusted of course but not a big margin for error.

Craw can tell you more about phosphorus levels in Lafayette because I haven't dealt with lawns in South Louisiana in 4-5 years.

Ever deal with Zoysia? I have Palisades in my front and going to put out 1/2 lb N probably using what Crawdude with the Lesco 24-2-11. One thing I've been told is to go really light and spoon feed zoysia so you don't create a thatch monster.

Zoysia is the woman of the grass types. It doesn't do what you want it to do, it does what it wants whenever it feels like, and it can have an attitude. From what I have experienced Zoysia will look great the first year you install it, it will have a sophomore slump, and then you can really start to manage it.

I’d just apply the 15-5-10 for your first application. In the meantime you can pull some soil sample from the lawn for analysis by the LSU AgCenter and make any adjustments if needed for later lawn fertilizer applications, if you plan to make 1 or 2 additional lawn fertilizer application this year.

In the rich alluvial soils of Baton Rouge/Lafayette - non-piney wood areas of south LA - pretty uncommon to see soils deficient in phosphorus. But that said you can’t always count on that.

For example, my lot in BR the front yard is (was) a bit low in P and a soil test calls for P in the lawn fertilizer even for centipede which does better in lower P soils, but the backyard requires no P - and this is 90 x 180 residential lot, not acres of land. But when the subdivision was built in a old dairy pasture, streets were cut down so that homes would have about a 3 feet or so elevation above street level. That excess street soil was spread on empty lots changing normal surface soil characteristics. Hence why having a soil test analysis on a home lawn for baseline info is helpful.

What fertilizer ratio do you like on zoysia?

16-0-8 for granular and 17-2-5 if liquid. I’d love if some gave me their zoysia lawn and said do what you want. There is a lot I’d like to test on a zoysia lawn.

Just go with Lowe’s 15-5-10 as indicated in the other post for LSUDBrous90 and apply 6 3/4 lbs per 1000 sq ft to obtain the 1 lb of N per 1000 sq ft recommended by the LSU AgCenter for St Aug. In the meantime pull some soil samples from the lawn have analyzed by the AgCenter. Based on the results, you can adjust the fertilizer type/composition for future fertilization applications.

I know most on lawn forums mow with reel mowers but for now my JD Rotary will have to do with sharp blades. I just wish I could get the HOC down to under 2 inches but not going to happen without major leveling.

I used LESCO 24-2-11 last year and have some left. I could return the 15-5-10 to Lowes. Which would I benefit more from polluting down now that I have the choice and not knowing soil conditions?
