You can tell that Summer is almost here when the grass starts to grow. Last mown in April, the lawn lay dormant throughout Winter and sprung* to life in September, requiring a thorough mowing by mid-October. Not even four weeks later and the grass is overgrown and badly needs a mow. Weather permitting this will have to be done on Sunday.
Perhaps you are becoming bored with my discussion of mowing, but this post is about a question. I was thinking this morning: every year we remove many kilos (dry weight) of lawn clippings. The matter that makes up the lawn comes from the ground, we haven’t used fertiliser or anything. So if we are constantly removing matter from the yard, why doesn’t the surface level drop?
Now you have a small window into my mind.
