Use a mulching blade on your lawn mower.
Mulching the grass while you mow will save a lot of time and money!! If you mow often enough you won't need to rake the grass! (Saving time and your energy.) And there won't be any clumps of dead grass killing your growing lawn. Instead, the small pieces of cut grass will fall through to the dirt below and help fertilize it. (Saving $$$!)
