10 . It is late autumn—millions of gardeners across the northern hemisphere, pulled on their thickest sweaters, spent hours clearing large piles of leaves and packed them into plastic bags at the end of driveways.

In the US alone, nearly 10 million tonnes of garden waste go to landfill every year. That is a large amount of effort, not just from an environmental viewpoint but from that of our aching backs, too. So where does this advice come from? Well, it largely comes from the belief that thick fallen leaves can make plants under them unable to breathe, especially shorter grass. They shut down important photosynthesis (光合作用) and get in the way of the growth of the shorter grass. However, this received wisdom has recently been questioned by researchers at Wisconsin University.

The key finding of their new research was that although clearing fallen leaves is one of the most common gardening practices, it makes very little sense. In natural ecosystems, fallen leaves help return nutrients necessary for healthy plant growth to the soil, which greatly improves soil condition. Removing leaves year after year breaks this ecological (生态的) balance. Letting some leaves stick around to cover your garden is a great way to help your grass and the local ecosystem.

They further explained that if up to 50percent of your grass lawn (草坪) is covered by fallen leaves, you might as well go back indoors and put your feet up. The advantages of this light leaf coverage far outweigh the disadvantages—the leaves will quickly break down and help next year’s lawn grow far better than if you had cleared them. Only at over 50 percent coverage do the Wisconsin researchers recommend clearing.

So why not consider leaving the leaves? Save time, carbon and effort, and in exchange get a healthier lawn from this garden waste—that seems like a pretty good deal. And how many plastic bags could be saved by simply not binning fallen leaves every year? In the US alone, about 700 million.
