Excessive leaf matter on your lawn going into winter is bad for several reasons. First, it will smother the grass and if not removed very soon in the spring it will inhibit growth. Second, it can promote the snow mold diseases. And finally, turf damage from critters (voles, mice) can be more extensive in the spring.

Second, it can promote the snow mold diseases. And finally, turf damage from critters (voles, mice) can be more extensive in the spring.
Leaves can smother your lawn and eventually kill it.
This can quickly kill your lawn if the leaves are not picked up for several weeks and create a breeding ground for certain insects and pests. As the leaves begin to rot, there is also an increased chance for fungus and mold growth.
Yes, grass can grow back over leaf piles. The leaves will eventually decompose and provide nutrients to the soil, helping the grass to regrow. However, if the leaf piles are very thick, they may block sunlight and prevent grass from growing beneath them.
Leaves are biodegradable, meaning that bacteria or other living organisms can decompose them. While whole leaves take a longer time to break down (about two to three years), cut up leaves decompose faster (about one year) and can provide plenty of nutrients for the soil.
"Leaves naturally break down and they turn into soil, so by composting you're speeding up that process so that you can get to that end point more quickly."
Phosphorus and potassium are just two examples of the elements that dead leaves can contribute to your lawn after they break down. By letting leaves decompose into the soil in your yard, you will be saving yourself time and money on fertilizer for the next season.
It's best to rake leaves while they are dry and before the frost and snow begins. Many individuals like to keep up with leaf maintenance by raking or mulching them as they fall, while others may wait until all the leaves have fallen to the ground before raking.
Dormant grass can start to green up within 7–10 days with proper watering and care. If the grass is dead, it requires reseeding, fertilization, and consistent maintenance, which could take weeks or even months.
Mowing your leaves - also known as mulch mowing - into tiny pieces on your lawn, is healthier for your lawn and soil than piling or bagging them to be removed.
Pro: It's Good for Your Soil
Mulching leaves into your lawn allows them to break down and boost the soil quality. Maple leaves, for example, have even been shown to reduce weed seed germination. Other leaves, like honey locust, are high in nitrogen, which helps grass and plants grow.
Compost them
If you have a designated compost pile, dead leaves are a great addition to the mix. Again, they'll decompose faster if you shred them first. “The leaves, combined with other materials, can create a wonderful compost pile that you can then use in your flower beds or gardens come springtime,” says Engledow.
Broadleaf, deciduous trees lose their leaves in fall to conserve water during colder months. Coniferous trees' needles are much better at retaining water, so they keep them year-round (a trait that has earned them the moniker of “evergreen”). One of the best defenses that trees have against the elements is their bark.
Long grass provides a meal for insects and small animals, such as voles, who will feed on the grass under snow cover throughout the winter season. This puts your lawn at risk of disease, providing an opportune place for mold and bacteria to take over.
Thatch, a layer of dead grass and root matter, can impede water, nutrients, and air from reaching the soil if too thick. Regular raking breaks apart and thins the thatch layer, which allows for enhanced grass root health and overall lawn vitality.
As temperatures drop, fallen leaves and the soil underneath offer crucial habitat for all kinds of creatures, including salamanders, frogs and rodents. Shepherd noted that this shelter is especially important for the smallest animals, mainly insects and other invertebrates.
If your grass is actually dead, there's nothing you can do to bring it back other than plant new grass. Brown grass, however, can green up following proper care. Oftentimes, that just means water, nutrients, and cooler temperatures for northern lawns and warmer temperatures for southern lawns.
Cool season turfgrasses like Kentucky Bluegrass, Perennial Ryegrasses, and Tall Fescues can tolerate a period of drought in the summer. Grass blades turn brown as they lose available moisture. If the drought doesn't last beyond 3-4 weeks, most of these areas can re-grow new, green blades when wet conditions return.
If you have dead grass, fertilizer will do nothing to bring it back; you are essentially pouring high-quality fertilizer down the drain! But we understand that some homeowners aren't sure if their lawn is dead or just dormant, so they fertilize to test.
Leave them
To best support wildlife and soil health, experts say leaves should be left where they fall. A hearty leaf cover provides a habitat during the cold winter months for critical pollinating species such as bees, butterflies and moths.
When you see dead leaves, dormant stems, or brown parts of leaves, cut them away. It's fine to pluck dead leaves or stems with your hands when possible, just don't pull too hard, or you may damage the healthy part of your plant. For tougher stems or to remove brown leaf tips and edges, use scissors or pruning shears.
Most of the time, however, you'll be doing your garden more harm than good by exceeding recommended speeds: rocks and dirt flying everywhere, destroyed grass and tears of dread. Treat leaf blowing the same way you would any other garden job. Take your time and do it right; Your lawn will appreciate the effort.
Fallen leaves that cover the surface of the soil act like a blanket and help to protect the soil. Leaves that fall from trees in the forest help to insulate the soil and protect it from rapid temperature changes.
If fallen leaves are left on new grass seed for too long, they can block access to necessary sunlight and kill it or prevent sprouting. Once the grass seed has germinated and grass blades have grown an inch tall, you will not disturb the soil significantly if you walk on the lawn.
