I put down some prodiamine today . When should I apply a post emergent? I see my Poa annua and some other weeds in my yard already.

What type of grass?

Treat weeds you see growing now with post-emergent - in fact always treat for weeds when you see them, you get better control when they are young and before they produce seed heads. If that is 12 months per year, then so be it.

Poa is a little difficult to control post emergent and atrazine with surfactant is your best bet - I’d suggest using the winter weed cocktail mixture (but not if you have bermudagrass, unless it’s dormant) I posted above for the weeds growing now, which includes the Poa, and expect to re-spray in a few weeks. The key to Poa control is application of pre-emergent this fall, mid-Sept/earlyOct.

P.S. you don’t use that cocktail when temps hit high 80s, it can damage the lawn, you need to use other herbicides that don’t have a temperature restriction.

re: Is it time for pre emergent in South LA?
So I left the store this morning with just some granular Hi-Yield pre emergent and my plan is to use a spreader today. Is this a good plan? As for the shite all in my flower beds, is it better for me to just pull those by hand or should I spray them with something?

Yes indeed it’s a good plan. Flowers beds - your choice, I usually do both. If the weeds are large and easy pulled, I remove my hand, low growing weeds, I usually spray. Then mulch the beds, 3 inches of pine straw (my favorite mulch, at least for street views), and you can sprinkle pre-emergent in the flower beds, but only if you don’t plant flower seeds, and don’t use atrazine in landscape beds.

All I’ll say is apparently MSMA is a great herbicide to use on Bermudagrass for weed control but it is no longer labeled by EPA use on residential lawns, so technically it would be a violation of federal law, unless you have a old supply still labeled for lawn use. Your call.

First thing I learned in pesticide training, “The LABEL IS THE LAW” and it’s the first stated at the top of any pesticide label.

I just applied some Pendimethalin to my yard this morning. First time using it but I got a 50lb bag for free. I have 2 more 50 lb bags of Dimension which I’ll apply in 6ish weeks.

Well, I have been using LESCO granular Dimension 0-0-7 (dithiopyr) with good success, and b/c so many on this board use Prodiamine I thought I’d try it so I purchased granular LESCO Stonewall 0-0-7 (prodiamine) and I applied granular Dimension in my front yard, and granular Prodiamine in my backyard a few days ago.



I came across this and it had good ratings and would like to know if you would please share your thoughts about this product

That’s too expensive you can get Dimension under a LESCO label at HD 50lb bag for $49

Yes the Fertilome Dimension it is an excellent product and it is what I used until last year, when, as OleWarSkule stated, I found the granular LESCO brand Dimension (same formulation) at a significantly lower price, in Baton Rouge at a Site One Landcape Supply. You don’t have a Site One Landscape Supply in Hammond, but there is another one in Mandeville. If I recall correctly the LESCO brand from Site One is about $32 for a 50 lb bag (apply 4 lbs per 1,000 sq ft). But check the website of Lowe’s for LESCO Dimension, OleWarSkule and others have said they carry it, though I’ve not recalled seeing it at the Lowe’s near me.

If you want to take the 45 min drive to Baton Rouge, I can tell you where to get all these products I’ve recommended at 2 stores, including the lawn fertilizer, within 5 minutes of each other, on Siegen Lane between I-10 and Airline Hwy. One trip and you can buy everything you need for the rest of the year. But check for locations that carry these products near you first.

Thanks for all your help bro! I really appreciate it. I live in the Mandeville area now. I'm going to try to see what I can find out in my local area so I can treat the yard this weekend in anticipation for the rain on Sun/Mon. Seems like my local ACE Hardware store has everything for the winter cocktail mix.

re: Is it time for pre emergent in South LA?
Good - then I suggest you go to Site One in Mandeville and purchase granular Lesco Dimension 0–0-7 pre-emergent, and later if you want to switch to a prodiamine granular pre-emergent Site One sells Lesco Stonewall 0–0-7. They also sell a Lesco 15-5-15 lawn fertilizer which would be good for your centipede lawn - I use it. I also purchase a Lesco 14-14-14 controlled release fertilizer I use on shrubs, trees, etc in landscape beds.

Site One will also sell most of the other liquid herbicides mentioned, maybe under different names, but because they sell mostly to landscape/lawn maintenance professionals those products are usually sold in container sizes larger than you will need, so shop for those elsewhere, hardware stores/independent retail plant nurseries, where you can purchase smaller homeowner quantities.

Lastly, I suggest you have your lawn soil analyzed by the LSU AgCenter for soil fertility. Soil sample boxes can be picked up at many retail plant nurseries, or stop by the Hammond Horticultural Research Station - cost is $10 per sample and 3 samples per can be sent in. Instruction and bags in box. LINK Centipede grows best in acidic soil, which you might have in your area but you need to check. My soil in BR needed sulfur addition to lower soil pH suitable for optimal centipede growth. You can also purchase 50 lb bags of elemental sulfur at Site One if soil test results show you need it.

Do you guys think it is safe to put something like image down today, it rains for the next day or two, put down high-yield ornamental turf and grass with dimension on Saturday, and then fertilize on April 1? This is for zoysia.

What kind of Image - there are several different Image formulations. You have a bottle? What does the label say about applying relative to rain?

Putting down the Dimension as soon as you can is OK. I’m not to familiar with zoysia - does it green up fast? I think after you are able to cut the lawn twice after the Zoysia greens up is a good time to fertilize. Centipede is a little slow to green up so April 1 is generally a good target date. Bermudagrass and St Augustine green up earlier so often mid-March is good time for the first fertilization (south Louisiana of course).

re: Is it time for pre emergent in South LA?
I will have to look at the label when I get home. It's the green one, NOT the purple one that is just for St. Aug. I know it is safe for my grass as I have used it in the past. I was more so asking if I could use them so closely together.

Zoysia tends to green up slower. I will definitely wait until a cut or two is needed before I fertilize. I would like to have a 1/2" of topsoil added to the yard or at least have someone help work on some of my low spots.

I'm nothing close to an expert. My yard is complete and total shite right now. I have a thread where I asked for help and Crawdude has been delivering great info. If you are anything like me, that thread should help you. I asked tons of questions and Craw brought good info on everything to do.
