Lawn Care@Ninomaru Park in Kummaoto Castle
On January 20, 2025, we were walking around Ninomaru Park in Kumamoto Castle. Sprinklers were watering the grass in the park. Location: https://maps.app.goo.gl/XnUMPDhFE6zTQikT9 The watering was part of the lawn renewal work. We learned that this kind of tedious work is necessary to maintain a large lawn. I think that this walk was a wonderful field study for us. Watering Photos A whitish soil has been spread all over the square. If you get closer, you can see that it's also sprinkled with lots of small blue granules. After researching online, I found that the small blue granules appear to be granular fertilizer. This is a fertilizer developed in the US specifically for lawns.
