I used Lesco 0-0-7 in the Spring.
What do y'all use?
I'm looking to lay it in a month from now.
I never did get to put a 2nd drop of fertilizer on my centipede this year due to weather.

I spray prodiamine. Has worked well for me for a few years. Probably have to put it down late this year according to some reports of it being warm for longer.

Do you live elsewhere or still put it down while hot?

0-0-7 isn’t a pre em unless it has a chemical you didn’t list.

Yes, he’s not saying he applied LESCO granular Dimension that has a little potash in it. Unless it’s LESCO Stonewall (Prodiamine) that also has 0-0-7 NPK.

I got a bag of this last week at Site One and plan to put it down at the end of the month/beginning of October. St. Aug. in Baton Rouge. Ronk/Crawdude, is this what I should be using?

This is on sale at Lowe's, but of course my Lowe's does not have any. This is what I used last year.

Yes, it’s a good pre-emergent and that is an appropriate time for fall application for S LA - be sure to water it in the absence of rain.

As craw said you can use it. I use it in the spring for crabgrass. Specticle in the fall.

For south Louisiana, typically in the first 2 weeks of February. You want to apply it and water it in before soil temperature hits 55 F, the germination temperature for crabgrass.

I really liked The Anderson's fertilizer I used a year ago so I just ordered their Barricade granular while it's still 10% off this weekend LINK

Here is a soil temp gauge you can bookmark for your area

Ronk, Crawdude, and other experts: for pre emergents

I see that Lowes offers Lesco 0-0-7 Stonewall .68%

on the other hand, Siteone offers Lesco 0-0-7 Stonewall .43%

Is there a big enough difference in these that it matters which I pick? Lowes is def a more convenient drive for me.

When exactly do you put pre-emergent down in the fall in south Louisiana? In the next 4-6 weeks?

For a lawn planted in mid-July, is it safe to apply preemergent this Fall, or should I wait until the Spring? If I apply in the Fall, it would be last week of September/first week in October going off of historical soil temperature in my area. I'm guessing the grass is too young.

AFtigerFan, others are more expert than I but nevertheless I say wait till Spring. Better safe than sorry. Get after things in Spring once fully established.

I had about 20 pallets of Tifway 419 Bermuda planted at the very end of May this year and I plan on doing a fall pre-emergent.
