I am sure you can use Oxadiazon/ronstar

 

agree, ronstar g if you want granular. It smells to high hell, and need to read the warnings but it’ll get ya taken care of.

 

Simazine for fall/winter. In Orchards, there are grassy weed pre and post herbicides that will not harm the trees or clover.

 

Thank you guys, I’ll keep the train rolling, smelly is better than crabgrass. Landscapers in my area told me I was nuts to try and seed zoysia, but it’s filling in fast and dang near weed free. Im doing 10-10-10 in steady doses and, Celcius + quinclorac + and certainly cleared house after my 4th mow with very little impact to my grass. I have hard nasty clay that’s been a bigger to improve. I wanted to do a cool season grass but I get 10+ hours of sun, and it gets roasted.

 

Could I use simazine for my spring pre emergent? Or does it vanish too quickly? I prob need 2 good months of growing and the yard will be filled in.

 

Zoysia is very tolerant of moderate rates of Prodiamine. Next spring, you are fine to apply the split rate program for it. Get season long control of grassy weeds

 

I live in the Atlanta area and this fine looking grass always pops up in early spring in my zeon zoysia. I can't think of the name it is called but it looks like fescue. It seems to get burned out during the heat. I have had pretty good luck working with Tony at C.A.L Landscaping here in Atlanta, Ga. 770-891-2245. I just have not had time or the patience of dealing with it anymore. They resodded my yard and maintained it, very reliable and trustworthy.

 

nutsledge is the name

 

Sedges in early spring? Got a pic? I am zone 7 and sedges don’t pop their heads up until we stay above 70ish right after Bermuda greenup around May. They tend to like warm weather is why I ask. Right now and for the next few months I am fighting poa annua and poa triv that broke through the pre ems. Prior to green up of desired turf and would last until around June if nothing was done to it. Just curious.

 

That might be the name I am looking for. I dont have a photo yet.

 

And sedges will not get burned out in the heat as they thrive in heat and spread quickly. I think if you pull up poa annua or poa trivialis you will see the weed you are talking about.

 

Since you have zoysia if it is what I think it is, Poa, Certainty or Negate will be your best affordable options as a homeowner. Certainty is the best option out of those two due to Negate being sold in a per Acre bottle. It Negates is a little cheaper per the sq ft and imo works a bit better but you literally have to have what we call a “drug scale” to measure out the amount you would need. 0.10 oz per 1000 sq ft. Certainty comes with an easy to use scoop for smaller amounts down to one gallon mix that will blanket treat or spot spray 1000 sq ft. So I’d go with the C. Note that either will take dang near a month to work after spraying it. But it will work. Just give it time to do its thing and be patient. Good luck.
