Bermudagrass and other weeds cropping up in Zoysia

Yes, you can spray that in zoysia to control bermuda. It will be a constant battle and will yellow your zoysia. Focus on that before mixing something to control broadleafs. You throw something like celsius or msm and you'll start damaging your zoysia.

Should I spot treat the areas that I'm seeing the bermuda or should I treat the whole yard? So far it's isolated to a couple of areas. I guess spot treating those would make more sense. But can I treat a large area (like 100 sq ft) or do I need to really isolate it to where I see the growth? Sorry for the questions. This is my first effort to ever really maintain a yard.

And should I do this on a schedule like every 4 weeks? From my understanding, I'm just managing the bermuda at this point. So it'll need to be a routine. Just really don't want to flush my sod money down the drain by putting something stupid on my yard.

Tifway, you're right. It is just one of the native weeds that were at this house before I bought it. The previous owner HATED being outside in any fashion. So he just let it all grow and when he did mow, he would mow it as low as he could.

The soil is really not great here. We're about 2 blocks from where they were mining gravel. I walked back to where the mine was and it's literally an 80' sheer ledge and the entire ledge is gravel and rock. I really want to plant some trees but I'm going to have to dig as big of a hole as I can and backfill with good dirt before planting any trees.

I sent off a soil sample last week to see what all I'm lacking. I suspect the soil is alkaline, and lacking a lot of nutrients. I'll post the results when I get them.

I would do a test spot. Treat the bermuda area and check it in 3-4 days. If it isn't starting to yellow then treat all of the bermuda areas. I suggest only treating where the bermuda is. No since in over treating areas. While zoysia tolerates these herbicides it is key to remember the word tolerate doesn't equal loves it.

Grass issues are so odd from one person to the next. My parents have Empire Zoysia and it’s growing into their neighbors hybrid bermuda and chocking it out. I didn’t think you were supposed to fertilize zoysia with 29% nitrogen? The turf farm told my dad to use something along the lines of 15-0-15 and don’t put it out more than twice a growing season.

That bermuda loves high nitrogen fertilizer. Turns it green and makes it go go go.

So I just got my soil sample back. What can I do for now that won't hurt the yard?

Thanks man. Overall I'm really happy with it so far outside of the bermudagrass being a PITA. It seems to have slowed down in this heat so hopefully the zoysia has time to choke it out a little more. Think I sourced mine for $270 a pallet also. It was priced at $300 but a buddy works for a landscape company and I got their discount. It's mostly growing like wildfire but I do have a couple of spots that are concerning. Not sure what is different about this particular area but it's just kinda struggling. The lighter green area is what I'm talking about. The brown spots are where the dogs have peed. I'll have to pull a couple of plugs to get those healing up.

The lighter green spot might just be lacking water in this heat. Try to hand water just that area and see if it helps. You should see a difference in about 2 days if it’s just lacking water.

Yes, there are risks with fertilizing in the heat. Temps over about 85 degrees is stressful for the lawn already, so just keep that in mind. Organic (or slow release) would be better than synthetic ferts right now.

Pee spots suck, I trained my dog to do her business in one section of my lawn that is out of sight. She destroyed the grass so I let the weeds grow…better than dirt! Just be mindful that those thin or dead spots are prime real estate for weeds and that Bermuda to grow.
