Fall leaves are a bounty for gardeners


Leaves contain 50-80 percent of the nutrients the trees drew from the earth before the leaves fell to the ground. You can use them to replenish the soil and nourish all that grows within it.

As lovely as hardwood trees appear with their leaves in glorious shades of red, yellow, orange and rust, my favorite part of this season is after they have fallen. The now brown leaves begin to blanket my lawn and beds and I know that it is compost time!

Where most people see leaf debris as just that, along with hours of raking, bagging and hauling, I see garden beds blanketed in rich organic compost. These leaves contain 50 percent to 80 percent of the nutrients those trees extracted from the earth before they fell to the ground. I will use them to replenish the soil and nourish all that grows within it.

Earthworms will feast on this debris, then burrow deeper into the soil depositing that matter as castings, adding even more valuable nutrients, oxygen and drainage in the process. Beneficial fungi and bacteria will assist in the decomposition process, consuming this raw leaf material and returning it in a nutrient-rich form that can be utilized by plant and tree roots more efficiently and effectively than anything man has ever created.

Mere months after these shredded leaves are applied around my garden, they’ll transform into matter that promotes the life of soil dwelling organisms which in turn fortify my plants and trees to be more pest and disease resistant. And have you ever stopped to consider that no matter what condition soil is in, compost will help make loose soil retain moisture and compacted soil drain better?

I also see the opportunity to reduce landfill waste by 20 percent – since that is how much space our yard debris occupies of these facilities. Rather than viewed as unnecessary trash, these leaves and other grass clippings could be going into our own gardens to enrich the soil while reducing the need for supplemental fertilizers and other harmful chemicals.

Yes, in a few weeks, I’ll be gathering up and shredding not only the leaves falling from my trees, but from my neighbor’s as well. I also have the landscaping crews ready to bring me the leaves they’ve collected from their jobs too.

What leaves I don’t spread into the beds, I’ll store somewhere else in my yard. I’ll worry about that later. But for now, bring me all you have. It’s my organic fertilizer, multi-vitamin and soil conditioner all-in-one; it’s plentiful and it’s free. It doesn’t get any better.
