I have been using buckets of raked leaves to build the soil around my fruit trees.
Would love to sell some of those buckets to Yuppies in Suburbia land, could probably get $10 a packed bucket.
Leaves raked from the forest, just like Trump recommended.
though actually from a fire point of view, leaves are the easiest thing to have on fire. they don't actually need to be raked.
It's the 1000 pound accumulations of dry wood that a homeowner or fire-fighter can't put out with a bucket of water that need to be removed.
I have never taken a leaf or stick to the curb. My yard has gained about 9 inches in depth in 11 years. You can see it perfectly along my privacy fence. It grows a very nice garden for a city lot. And has worms that look like small snakes.
