Is this bent grass mixed with Kentucky Bluegrass? #879645
Asked July 31, 2024, 5:41 PM EDT
We had this sod laid down last August and this is what it looks like. The company that put it in says it is Legend, Blue Note and Prosperity Kentucky Bluegrass. We had the Lawn Doctor come out and he said it had a mixture of Bent Grass which is not suitable for lawns and is usually for golf courses. I need to really know what is causing this as it should be under warranty, and if they put in the wrong type of sod then they need to replace it. But now I don't know who to believe. Please help if you can.

Sue,
I can't seen the individual grass plants clearly enough to ID to species. In any event, that looks like heat stress which would not be unexpected given how hot and dry conditions have been plus the fact that your young lawn is baking next to an asphalt street.
If you want to pursue an ID on the grass, bring a fresh sample to the Denver County Extension office, roots and all. Call first to make sure someone is available to help you,

Thank you I may just do that and bring a sample. However, our neighbors lawn doesn’t have this problem next to the street and has full sun, theirs revived after increasing their water as it was looking like ours early in the summer, but is fine now.

Your lawn's discoloration may or may not be the same problem as your neighbor's. Even assuming you have the same species of grass, the timing is different, spring and summer weather conditions are different, and I'm assuming (maybe incorrectly) that your neighbor's turf has been growing longer than yours which suggests that it has thicker roots than your new lawn. All that can make a difference in what's going on. The fact that upping the water seemed to green up their grass does suggest a drought or winter-drought problem but without additional information, I wouldn't want to speculate.
