Leaf mulch

Those of us in deciduous forest habitats (and with lots of deciduous trees in our gardens and neighborhoods) have plenty of free organic mulch.

First, save your own leaves -- don't let any of those go to the curb.

Second, snag your neighbor's leaves.  We collect bags full of them.

Finally, corral the leaf-vacuum trunk (if available) and have them dump a load or two in your driveway!

Why buy hardwood or pine bark mulch for your garden when leaves are free?
