I was going to link directly to your pics but they are huge. If you can make them smaller (like 800 px wide max), then use the following code to link them directly The quotes are important. Your links are good, just too big for this forum. Looks like too much shade and/or water. Near the patio that could be urine damage. Usually it is a much more well defined spot, but your grass is so thin. Where do you live? If you live in the south, would you consider St Augustine?

Zoysia is glacially slow to refill once it has been killed by disease. Just out of curiosity, why did you decide to buck the system and not go with St Augustine? You will do yourself a huge favor in terms of minimizing future hassle, time, and cost if you just resod with St Aug right now. Get it over and done with. Otherwise you'll be sodding zoysia over and over to keep up with the brown spots. Every time I see a zoysia lawn go in in my neighborhood, I put it on the calendar. So far only one lawn has gone over 2 years. They are just starting their third year with no problems at all, so I guess I need to find out what their secret is.

"I am looking to buy a self-propelled mower to cut my zoysia lawn. I want to bag the clippings." RB> There are several mowers that will do an excellent job of bagging. Look at models from Toro, Lawnboy, Snapper, John Deere. My personal favorite is the Toro Super Recycler. "Most importantly, I need the mower to be able to walk through the lawn and cut the thick zoysia lawn." RB> You will have a much better chance of finding a mower that rolls through the lawn. Most any mower from one of the major manufacturers listed above will easily cut wiry heavy grass without bogging down if you keep up with a regular mowing schedule. "Suggestions on which mower, RB> See above. approximate cost, RB> Probably looking at $550 +- for a good Toro Super Recycler. Models from the other companies listed above will have similar features and be comparably priced. "and where to buy would be greatly apprecicated." RB> Your location is shown as USA, so it's kinda hard to pick a dealer for you. Just check manufacturers websites for dealers close to you. You will get a better grade of mower and service if you buy at a local dealer.

You search "Zoysia Grass" on GOOGLE. What you do now? has already been answered: NOTHING NOW IT IS TOO LATE and YOU OVER FERTLIZED so all you can do is wait till next Spring. Next Spring when you start to see it green up, whack it down as low as you can, and rake up all the debris. Then you will need to de-thatch the lawn with a Vertical Mower (aka Power rake). After verti-cutting remove all the debris again. From this point you can top-dress with top soil or compost if you wish to further break down any remaining thatch. Once you see it about 75% green, apply a complete slow release urea fertilizer with a 3-1-2 or 4-1-2 ratio fertilizer like 15-5-10 or 20-5-10, at a rate of 1-pound of nitrogen per 1000/ft2. Repeat one more fertilizer application 8-weeks later with just plain ole straight slow release urea. After that you are done for the year until next spring with fertilizer. If you go to some place like Lesco and buy a 50-pound bag of 15-5-20 (product number 500258) and 39-0-0 (000777) will cost you about $50. With a 3000/ft2 lawn that should last you many years (7-years for the 15-5-10, and 19 years for 39-0-0), that works out to be less than $5 per year. How much does ScottÂs charge per year or a single application? What you use as a fertilizer; organic, synthetic, or synthesized organic (urea) is not near as important as proper fertilizer timing, mowing and watering. Get these three right and things will work out. If you go the organic route plain ole soybean meal is the best IMO in terms of effectiveness and economics. If you go the Soybean route it is about 300% more than the synthesized organic route of using slow release urea. Considering the size of your lawn of 3000/ft2 not a lot of money to consider. Using a commercial organic product will be considerably more and less effective than soybean meal. For 3000/ft2 lawn you will need 1 50-pound bag of soybean meal for each application which depending on local prices may be as high as $12 due to the ethanol hoax. Mowing is straight forward. For Z-52 it needs to be maintained between ¾ and 1-1/2 inches and no higher. The height you choose depends on what kind of mower you have. If you have a reel type you can go down to ¾-inch. Otherwise as low as you rotary mower will allow without scalping. Watering is simple. Z-52 is very drought and heat resistant. All you need to do is water when needed at a basic rate of 1-inch per application without run off. Sounds like you already are on track to know how much time it takes to apply 1-inch. Now all you need to do is figure out when by letting the grass tell you when it needs watering. Simple; you look at it and walk on it. That is all there is to it. Each spring check on the thatch build up as Zoysia is notorious for thatch build up especially when over-fertilized and allowed to grow too tall. General rule of thumb is Zoysia needs de-thatched every 2-years or every year if over-fertilized.
