Break the clumps up with your foot or hands so they are open. Leave the clumps to dry for 8 hours. Once dry, they are easier to spread.
Rake the dry clumps into a pile with a regular garden rake. If you are going to use them as mulch, rake the pile close to the garden.
Pick up a pile of clippings using both hands and walk the yard, dropping them in a thin, even layer over the grass. If you are using them as mulch, spread the clippings by hand around the base of your garden plants in a layer no more than 1 inch thick.
