Well it has been planted for about 6-7 weeks now. It has been mostly surprisingly cool weather for the Memphis area with a good amount of rain. That combined with the sprinkler system in this yard this palisades zoysia has been getting a very good amount of water. So I'd expect this could be a fungus problem? But first of all the areas that stay the MOST drenched/swampy and get the LEAST light have been consistantly the most healthy out of all of them. So that doesn't make sense to me... but furthermore about 3 weeks ago I sprayed a good solid fungicide and haven't seen any significant rebound. So now I'm left wondering what's going on and am watching quite a few of these completely or 95% dead looking zoysia sod patches wither away into flaky bits of 'hay' while they get overtaken by the relentless hybrid bermuda which was weed-whacked and scalped back completely before placement of the sod and has since managed to not only regrow with zero sunlight (being covered up) and with zoysia sitting on top of it, but has managed to pierce through the sod and is now overtaking these 'dead/dormant' sod pieces. Have a look for yourself - I took pics of a variety of them. I'd say about 1/3rd of them range from 95% dead/dormant to 100% - they may show some green but it's entirely or at least mostly bermuda taking over. The other 2/3rds range from completely healthy looking to at least mostly growing to a couple with some yellowish tint to the blades, which concerns me but so far is very limited. I guess I didn't get any good clear pics but there are areas where almost dead sod is literally 2 feet from flourishing healthy sod... I'm thinking should I wait or just rip this stuff up and replace it with a second round of palisades?
