If you had driven past my house in recent days, you might have thought you were watching a movie in reverse. There I was, opening trash bags, dumping out leaves and spreading them over the ground.

These were bags left curbside for me by neighbors near and far.

It does seem crazy, doesn’t it, gathering up all these bags and dumping out all those leaves? But dried, dead leaves contain stored energy, the sun’s energy. Put them on or in the soil, as I have been doing, and they release their energy to support the growth and activity of fungi, earthworms and other soil organisms. Mostly, these are friendly creatures, and nurturing them allows them to thwart unfriendly organisms, such as those causing some plant diseases.

Besides disease prevention, when leaves are gobbled up by soil organisms, the nutrients in them are being released. Think of all those minerals taken in by a tree’s wide, spreading and deep roots. Just falling to the ground all around you, leaves are, pound for pound, about as rich in minerals as is manure.

NOT FOR EVERYWHERE

Of course, spreading leaves over the ground or just leaving them there in the first place is not an option for every site.

I have spread leaves over a hayfield in which I’ve planted chestnut trees. In coming years, these trees will shade out the grass; I’m just helping the ground become the leaf-blanketed forest floor that it will eventually turn into.
