At this time of year, many homeowners rake up withered plants and
fallen leaves out of habit. But nature puts those dead leaves and withered
plants there for a very good reason. A moderate amount should stay right where it is. They're a natural source of carbon and other nutrients.
For years, I’ve shredded excess plant debris into tiny
pieces, and put it right back on the landscape, using my lawn mower. Birds, butterflies and small animals utilize this
plant debris. Harmless insects do too!
They serve as food (remember the
food chain?) for the aforementioned birds as well as encouraging frequent
visits by migrating species.
Bare, exposed ground actually encourages “weeds”. Normal plant debris, left on the ground,
becomes an organic humus, resulting in looser soil and giving your soil an
ability to hold more water and nutrients, and resist weedy growth. Plant debris also acts like mulch.
Water doesn’t evaporate as fast, so your water bill should be lower. Your
plants will grow bigger and better. You can buy humus in plastic bags every
year, or let it accumulate naturally for free. It’s your choice.
Please keep in mind that I’m talking about a “normal” amount of
plant debris and leaves. If they pile up by an outside wall or on a sidewalk,
by all means clean up. (If you own a rake, which I don't)
