St. Aug Annual Maintenance Plan
Posted on 8/11/21 at 4:43 pm
Posted on 8/11/21 at 4:43 pm
Has anyone (i.e. Ronk/CrawDude/anyone else) put together an annual plan broken down by month for pre-emerg / fertilizer / post emerg / etc. for St. Aug lawns? I've searched the threads (there are many) and cannot find something that has been laid out all in one place.
Thanks!
Thanks!

January-spot treat with atrazine and certainty for grassy weeds and trimec for broadleaf.
End of February-barricade pre em. Same weed treatment as before.
End of March/beginning of April-barricade. Manor for broadleaf and nothing for grassy.
Tax day-25-3-5 granular fert.
End of May-25-3-5. Spot treat with Celsius for broadleaf and grassy weeds. If grey leaf spot is present don't apply fert. Apply iron and propiconizole.
First of July-25-3-5 or iron. Celsius
Mid August 25-3-5 or iron. Celsius
First of October-specticle if that is too pricey then simazine. Trimec for broadleaf
Mid November-if you did specticle then nothing. If you did simazine then do simazine again. Trimec for broadleaf
December-I put down potash but a lot don't.

I can email you a plan that I built if you want it. I don't know how to add the document on here lol. I fertilize every month during the growing season but only with a half pound of nitrogen with micronutrients applications as well. I also do an annual soil test so I know what to put down. My St augustine looks awesome I might add.

What's a plan like that cost roughly, out of curiosity? I ask because I obviously have St. Aug and wanted to start taking better care of it.
If you had to narrow that plan down to the bare necessities, what would it look like?

That is a pricey plan but a plan to make the neighbors stop and ask what you are doing. A cheaper version would be:
January-March=spray weed free zone on all broadleafs
Tax day=25-3-5 spot treat with msm
June=milorginite and MSM
August milorginite and MSM
October=simazine
January-March=spray weed free zone on all broadleafs
Tax day=25-3-5 spot treat with msm
June=milorginite and MSM
August milorginite and MSM
October=simazine

I'm sorry man. I'm completely new at this. I'm assuming the bolded parts above are brands? Or are they chemicals that various brands make? Also, what is "25-3-5 spot treat"?
Remind me to buy you a beer or three if we ever meet...lol.

Weed free zone is an over the counter product. It works well but should not be sprayed at high temps. Fertilize with a product that has roughly 25% nitrogen, 3% phosphorus, and 5% potassium. Spot treat=only spray the weeds. MSM=metsulfuron methyl. It is a really cheap and highly effective herbicide. Milorganite is a low nitrogren organic fertilizer. Simazine is a chemical name. It is a pre emergent.

ronk - you got a schedule like that for Centipede?
Posted on 8/25/21 at 11:21 am to Bayou
Spot treat weeds. Put down a spring and fall pre emergent and then don't do anything. Centipede hates a healthy soil to be honest. If it looks bad maybe throw some milorganite on it.

Just got my bottle of simazine per your rec to combat the insane amount of rescue grass I had earlier this year.
Planning to spray this weekend (DFW)

I’d wait. Rescue won’t be germinating for some time. Unless the temps change drastically I’d do an app 30 days from now and 60 days after that.

Ronk - still good to put down Simazine spray this week?
Posted on 9/19/21 at 7:29 pm to Azazello
Yes. Temps seem to be headed south. Poa will be germinating soon.

Ronk, was wondering the same for centipede. I can’t find a guide like this for Louisiana.
Also, can we mix sedgehammer in any of these to save a trip?
Thx for your advice.

I was halfway joking about the do nothing plan for centipede. A plan would look similar to this: January-prodiamine. 6 weeks later prodiamine. When the grass is 75% greened up I’d use a granular fert with N in the teens at 3lbs per thousand. 2-3 iron applications after that. Simazine I’m October

How much Atrazine per gallon of water? I couldn't find it anywhere on my bottle.
