Autumn is a season of visual splendor as leaves transform into vibrant hues. Yet, once the show is over, those leaves tumble down, often becoming a nuisance for homeowners. This has sparked spirited debates about the best methods for managing those fallen leaves.
According to the U.S. National Wildlife Federation’s Leave the Leaves Report, homeowners usually fit into one of three categories: those who leave the leaves as they are, those who rake them up, or those who mulch them.
Leaving the Leaves
Each option has its pros, cons, and environmental ramifications. Despite what its name suggests, “leaving” the leaves is more than just letting them lie where they fall. The National Wildlife Federation describes it as intentionally arranging leaves and other yard waste to support wildlife, in garden beds or under trees, for example. Simply letting a thick layer of leaves accumulate on your lawn isn’t advisable, as grass requires sufficient light for healthy growth.
Opting to “leave” your leaves is an easy way to recycle them, benefiting your plants. Leaves are nutrient-rich and, when they decompose, those nutrients enrich the soil, reducing the need for additional fertilizers. However, this method does mean your lawn will miss out on those advantages.
Mulching
Mulching, a slightly more labor-intensive process, involves chopping the leaves with a lawnmower, which hastens decomposition. The benefit here is that mulched leaves enrich the soil more rapidly. Mulching enhances soil structure by aiding in the formation of aggregates, small clumps of soil with pores that retain water and air.
Mulching is also practical for those concerned about leaves scattering from their property. Unlike store-bought mulch, which decomposes slowly and can form a water-repellent crust, leaf mulch is quicker to break down and more eco-friendly. It may not transform your lawn overnight, but it’s a step in the right direction.
Raking and Bagging
Raking and Bagging Leaves: A Closer Look Raking and bagging leaves may be the most labor-intensive approach to leaf management, but it comes with its own set of benefits and drawbacks. Stashing these leaves in your own compost pile not only enriches your compost but also reduces the overall organic waste, which otherwise could take much longer to decompose at a landfill.

Yet, it’s not all straightforward when those leaves are taken to a waste facility. The National Wildlife Federation (NWF) points out that leaves and yard waste make up over 13% of the country’s solid waste. While they are natural, these materials can have negative environmental impacts. Due to limited oxygen, these leaves can produce methane gas, a greenhouse gas that the U.S. Environmental Protection Agency (EPA) says is 25 times more potent than CO2.
The method you choose is really a matter of personal preference and how much work you’re willing to invest. While “leaving” the leaves is easier, it’s not the best option for grass health, since it needs light to grow. Mulching offers a middle-ground solution, allowing you to simply mow over the leaves. Raking and bagging leaves is a time intensive task, but these raked leaves can also be a valuable addition to your compost pile.
When making your decision, it’s also worth rethinking the traditional view of lawns as just expansive green spaces that stretch from one property line to another. Instead, consider the lawn as a functional area that serves specific purposes, such as a surface for walking and other activities. Besides being a space for leisure and social activities, your lawn can also serve as a more effective ecosystem. Landscape beds with various plants can significantly improve water filtration and are more efficient at absorbing CO2. By rethinking how you view your lawn’s role in your property and the environment, you can make a more informed decision that aligns with your lifestyle and sustainability goals.
