What is the purpose of leaf litter? Leaves, twigs and pieces of bark that have fallen to the ground make up leaf litter. Leaf litter is an important component of healthy soil. Decomposing leaf litter releases nutrients into the soil and also keeps it moist. It also serves as great nesting material, hiding places and protected spots for animals.
What does leaf litter do to soil? Leaf litter can be a critical element of soil. Leaving leaves to decompose replenishes soil by releasing carbon, nitrogen, phosphorus and other inorganic compounds. The decomposition process can also foster interesting forms of life, like fungus, which often thrive in decaying leaf material.
Is leaf litter good for grass? Mulching lawn mowers are used to shred leaf litter into tiny bits. This natural mulch will eventually turn into a compost rich in nutrients such as nitrogen. Leaves left to build up on the grass over the course of a season will do damage to the lawn and will be hard on the mower when it’s finally mulch.
Is leaf litter bad? There is a cycle of life contained in the leaf litter and we destroy many forms of wildlife every time we remove these leaves. Trucked in mulch is not necessary when the leaves are left to cover the soil because the leaf litter acts as a natural blanket of mulch, controlling soil moisture and temperature.

Make your leaf heap as large as possible to hasten decay, and moisten it periodically if it becomes dry. Most leaves take about two years to break down.
What nutrients are in leaf litter?
Both leaf litter macronutrient [phosphorus (P), nitrogen (N), sulfur (S), calcium (Ca), potassium (K), magnesium (Mg)] and micronutrient concentrations were quantified throughout a 4-year period. Leaf litter [P], [N] and [K] varied significantly among soil types.

If you don’t have lawn under your trees, you can leave the leaves where they fall. The “leaf litter” will slowly decompose and over time will become mulch and fertilizer for your trees.
Does raking leaves destroy ecosystems?
“The leaf layer is its own mini-ecosystem,” the NWF says. “Many wildlife species live in or rely on the leaf layer to find food and other habitat.” Yep, raking leaves can destroy the seasonal housing accommodations that these species need to survive.
Do leaves decompose in lakes?
Wherever leaves fall, they decompose and restock the soil with nutrients and organic matter. Don’t “leaf” it up to someone else to solve this problem! Here’s what to do with your autumn leaves so that they nourish the soil and not unwanted algae.

Plants also store starches for future food creation, to provide sustenance in case of cloudier weather when photosynthesis cannot be used to generate glucose. In this case, the plant metabolizes starches in its roots to produce glucose and continue producing energy.
Should you remove leaves from flower beds in spring?
It’s also a good idea to keep layers of leaves off of beds of fall- and winter-interest plantings like pansies for the same reason. A thick layer blocks sun and risks disease in wet weather. But leaving leaves and mulching over top of them in spring is an acceptable and ecologically safe option.
Is it OK to leave leaves on grass over winter?
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.
