In Japan, grass isn’t a very common thing in yards. There are parks with grass, but most of them are covered in dirt and concrete with flower beds. Any grass tends to either be left to grow very tall or cut down too short.
Take this picture, for example.
This is next to the park near our home. It was once covered with grass, but now seems to be bare soil. The city workers cut the grass so short that they were cutting into the soil. It’s as if they were intending to kill the grass. But you can see the effects easily. Clumps of soil have fallen out and the slope is beginning to collapse. At the top is a playground. If they destabilise the ground even more, a heavy rain storm could cause a minor landslide. All because they cut the grass so much that it’s nearly all gone. Don’t they know anything about the stabilising effects of grass roots?
Unfortunately, I see this all over the place. These workers are not landscapers or gardeners, that’s for sure. They have no clue what to do with grass.
