Excessive leaf matter on your lawn as winter approaches is undesirable for several reasons. It will first smother the grass and, if not removed quickly in the spring, will inhibit growth. Second, it has the potential to spread snow mold diseases. Finally, critter damage to turf (voles, mice) can be more extensive in the spring.

It’s true that lawns go dormant in the winter, and the decomposing leaves won’t cause harm during that time.

If you still think that a leaf-covered lawn looks cluttered or messy, or you live in a community that requires you to keep your yard leaf-free, it’s best to rake them up and compost them.
Will grass grow back after it leaves?
If the grass has only been dead for a short period, it is possible to revive it. This is because the roots of most plants are still alive and can regrow. To revive the grass, remove the leaves blocking sunlight and preventing moisture from evaporating. You may also need to water the grass seed in the morning and avoid walking on new growth.

How long does it take for leaves to break down in a compost pile?
It can take months to a year for leaves to break down and become compost. The time frame depends on the type of leaves and the compost pile conditions. A pile of unshredded leaves with no nitrogen sources may sit for years before decomposing completely.
