Why should I not rake my leaves?
Subsequently, one may also ask, what happens if you don't rake your leaves?
Only a thick mat of leaves that remains on your lawn for weeks is likely to harm the grass. Leaves begin to break down after they fall, and gusts of wind often move them around. If the leaves aren't removed, the grass can die, and in the spring the lawn may have bare patches that require reseeding or resodding.
Considering this, is it better to leave leaves on the lawn over winter?
And while it is at least partially true that excessive amounts of fallen leaves can smother areas of a lawn when they're left in thick piles all winter, leaving the leaves on the ground as mulch can actually be an effective method of building soil and supporting a healthy yard.
Aim for raking leaves before the first frost or snow of the winter season. You can rake whenever leaves have fallen on the ground, but waiting until later in autumn, when most leaves are off trees, is the best time to make your raking chore one and done. The drier the leaves the easier it will be to rake them up.
