I’ve seen a lot of highways in Thailand. Highway medians are sodded with manilagrass (Zoysia matrella) as a matter of course (more about the cost of that below). I’ve seen some impressive vistas of this work in past years, but for safety reasons haven’t been able to get any photos.
Last November I saw a creeping bentgrass nursery in Japan. The nursery had been fumigated to kill seeds in the soil before the bentgrass seeds were planted.
I was surprised to see, scattered across the nursery, plants with big leaves that clearly were not creeping bentgrass.
