Hi all -

Looking for some advice for my month-old Zoysia sod. Last October, my entire yard was laid with Zoysia. I am located in North Texas, and we had a very rainy few months, followed by a few icy nights. The grass never rooted or greened over and was VERY splotchy (pictures below). They ended up coming out and re-sodding almost the entire yard 4 weeks ago, claiming that it looks as though it had developed a lawn disease likely due to the weather and time of year it was planted. I was also told AFTER the new sod was laid that I had grubs and was instructed to sprinkle Bayer Advanced Fungus Control for Lawns which I did myself (I wish they would have spread that directly on the dirt prior to laying the new sod). That also helped with my pill bug problem, there were dozens finding their way into my apartment every day.

It has been 4 weeks since the new sod was laid and the yard looks MUCH better. However, there are some brown spots and a few seams look to have not grown together quite yet. I do have a dog, but the company told me that her urine wasn't what had done the damage - however, I now sprinkle some water from a watering can over the area right when she goes so that the grass doesn't get burned.

They also left one area of the yard alone as the original grass had rooted. That grass hasn't taken over it's entire spot though, so there are quite a few muddy areas. From the original picture I am including below, it looks as though they just pulled-up the dead grass in that area, hoping the healthy grass would spread.

I have a large tree in my yard, but the entire yard gets full sun for at least an hour per day. Everywhere except under the tree gets another 3 or so hours of full sun per day. The areas with the brown spots actually get the most sun.

I watered 2x the week the sod was laid, and now water 1x per week when it feels dry. We have been getting some unseasonal drizzle days, so I am trying to take those into account when I decide if it is time to water or not. I don't have a sprinkler system, so I water it with a mobile hose sprinkler for 20-30 minutes. I live in an apartment complex where they are supposed to care for my yard (I pay for that amenity that I don't seem to be getting, as I paid to have my own sod laid when I moved in to a full mud-yard), but I have no idea what their schedule is because I haven't seen them once since the new sod was laid 4 weeks ago.

Questions I have:
1. Do I need to get a few pieces of new sod to place in the muddy areas, or will the grass that is there spread? Should I just fertilize? With what?
2. What do I do about the brown spots? Are these dead or dormant from too much heat or another environmental factor?
3. Can I use a lawnmower on my yard yet or should I just use a weed wacker? I had been told not to cut the grass for 4 weeks after the new sod was laid. The grass is looking like it should be cut now, especially the grass that wasn't replaced.
4. Should I use some sort of fertilizer on the brown areas?

I am including multiple pictures of the yard:
1. Original diseased sod
2. Immediately following new sod being laid
3. Full yard (current)
4. Close-up of brown spots (current)
5. Close-up of area with original sod that wasn't replaced (current)

I appreciate any help or advice! It seems silly to care much about a lawn for an apartment rental, but I spend a lot of time on the patio and outside with my dog and want to have a green, healthy yard.

Thanks!

I don't want to be a downer, but you are really going to struggle growing zoysia or any other grass in your yard. These are the issues I see:

Those spots are definitely dog urine burn areas. I water where my dog pees also, which helps, but it only minimalizes the damage. Also, I know people say that zoysia can withstand some shade... But the main word being withstand.. It will not thrive. In my experience, Zoysia really struggles when it doesn't have sun for most of the day and also struggles when it has to compete for water/nutrients from tree roots from below the ground. The wooden fence also isn't helping matters with it blocking out a lot of your sun.

I love my dogs to death, but I only let them go in a small area of my yard where I don't care what happens.

That is what I was afraid of. However, she is a little dog and the area with the spots isn't where she goes the most so why would just those spots be the only ones affected? I follow her and water immediately after she pees, not awhile after. I moved into this apartment strictly for the yard for my dog, so I don't necessarily want to restrict her to a certain area of the yard - also knowing this apartment isn't long term, I'd just have to train her to go in a certain spot somewhere else when I move.

I hadn't lived here in the Summer months before, so I had no idea how much of the yard the tree would shade. My neighbor has no tree and has full sun all day. She was able to plant St. Augustine that has held up quite nicely, but that wouldn't survive in my yard. These troubles explain why the apartment complex stopped laying sod for my stretch of units though since the same grass can't seem to survive in all of the yards.

Is there any treatment for burn marks in grass? Are you sure they aren't dollar spots or fungus?

@kadddd it definitely looks like urine issues. I have two female dogs, and every year there are spots that never green up. I'm assuming this is something that occurs either due to multiple visits by one or both dogs, or could be something that is related to the spring transition.

I would recommend either artificial turf or perennial rye. Perennial rye is literally "throw and grow". It doesn't like shade or urine, but throw out a few more seeds when bad spots surface.

Thanks @Spammage . As you said it is a throw and go seed, can i just sprinkle it right on the areas or do I need to prep the areas first?
Keep in mind that I'm talking about giving up on the zoysia. I'm just not convinced that it can endure given the circumstances. If it persists, then great! But if it doesn't, a perennial rye plan could keep you in real grass. PRG doesn't do very well with shade or urine, but is cheap and easy to continue to get new growth. It likely will be a different color (darker) than the zoysia too. TTTF might give you a more sustainable long term grass, but I don't know that it will survive shade where St Augustine won't.
