What is the maximum lethal soil temperature when sowing tall fescue. I am in Australia where soil temps can exceed 30-35C.
Hello, I did some research and found that the maximum high lethal temperature for cool season turf grasses is 40C to 44C (104F to 112F) and low-temperature kill is around -3C t0 -29C (26F to -20F). There are a lot of other factors like root, shoot, heat & chill stresses to consider with different temperatures. Click here for more information. I hope this was helpful.
