Many gardeners ask if it is necessary to rake leaves off of lawns or out of the gardens. Some leaves, such as those from red maple trees, are stunning lying on the ground, and are all-natural, which seem to be indicators to leave them where they are. Then, the sight of perfectionist neighbors raking leaves off of rock lawns are cause to wonder.
Garden Health, not Just Tidiness
There is a healthy reason for blowing leaves out of the gardens or off of lawns that is far more important than a tidy landscape. Plants need to breathe, and they can be suffocated if buried under a pile of leaves. With days becoming shorter, layers of leaves covering plants make it difficult for them to get as much sun exposure as they need.
If a thick layer of sycamore leaves is left smothering your garden without being shredded first, it's an open invitation to earwigs, pillbugs, cutworms, and other pests. When leaves are left on a lawn, brown patch, mold, and grubs are sure to follow.
A thick layer of pine needles or leaves often forms a barrier blocking water and nutrients from entering the soil. It also reduces airflow from getting down into the root systems of lawns and perennial beds. Matted leaves over your patch of wildflowers can prevent new seedlings from emerging next spring.

Mountain lawns are most active when the weather is cool. Fall and early spring are when bluegrass, rye, and fescue are most active, needing sun, water, and nutrients to strengthen their root systems. A mat of leaves blocking the sun will cause damage quickly. This is why a fall feeding with 7-4-4 All Purpose Plant Food is so effective.
It isn't necessary to rake every last dry leaf out of our gardens. Homeowners that hunt down every last leaf from their lawns are worried about maintaining perfectly manicured landscapes. A few leaves hanging out in a perennial bed, or tucked between yucca blades are not going to damage the plants. Only a thick layer of leaves will do that.
If you plan on mowing your lawn again this fall, the mower blades will shred any remaining leaves. A mulching mower shreds leaves, so they can lie between the blades of grass, becoming fertilizer for the lawn. I use the bag attachment on my mower for my Autumn mow to collect the shredded leaves and grass. I add the shredded mixture to my compost bin (How to Compost) or spread a layer of shredded leaves over next year's vegetable gardens.
Small-leafed trees are easier to clean up after. If you are planting a new tree this fall, you might factor in this variable. Leaves fallen from trees like golden locust, crabapple, ginkgo, and purple robe locust don't have the vibrant red colors of oak or blaze maple leaves, but they simply are blown away by the wind!
