The noise is maddening! I hate it. The commercial landscapers around here have really pushed the season in the last 30+ years. Used to be April through November. Now, it’s March through December. Over the years the landscaping industry seemingly decided en masse to add another month on either end of the growing and mowing season. In NYC and Nassau County where I now live, the law states that lawn maintenance with noisy a$$ machines may not commence before 8 AM. My next door neighbor’s gardener arrives every Friday morning at 7:40 and wakes me the F U.
The problem with starting cleanups too early is that many insects are still gestating and are in various stages of development until the temperatures are consistently above 50°F for a week. If you wait until then, usually sometime in April, the little buggers will live, birds will feast and thrive, flora will be naturally propagated and you’ll have a thriving ecosystem.
That said, probably some thirty five years ago NASA and NOAA scientists determined through direct and repeated observation over the course of many, many years that along the east coast of North America, the landscape “greens up” (I don’t know the correct terminology) eight minutes earlier every year. That was then. I don’t know if that’s changed since the report. Man made global warming has left a clearly observable and measurable impact on the environment.
