Conservationists and scientists say that to have better grass, people should mulch the leaves into their lawn rather than rake them and haul them away.
According to the National Wildlife Federation, taking away the leaves provides no benefits for the lawn in the long-run.
David Mizejewski, a naturalist and spokesperson for the National Wildlife Federation said that people should leave the fallen leaves on their property.
Researchers at Michigan State University conducted studies in the early ‘90s on the effect of leaves on lawns. They found that lawns that had been covered in leaves were the first to become green in the spring.
Dr. Thomas Nikolai, a specialist at Michigan State University’s plant and soil science department said that leaves are certainly not a problem. Of course, it is safe to say that big piles of leaves can hinder grass growth and may even kill the lawn.
However people can avoid that by mowing the leaves into small pieces that can do no harm, and will actually increase the lawn’s natural fertility by enriching the soil, Dr. Nikolai suggested.
In addition, maple leaves contain a chemical that prevents crabgrass and dandelions form growing, Nikolai added.
Robert Fulghum, an American author and former Unitarian Universalist minister, wrote in his book – published in 1989 – called “All I Really Need to Know I Learned in Kindergarten” that:
“Mine is the only yard in the neighbourhood with leaves. I like the way it looks very much. The gardening magazine does not like it. Leaves should be raked. There are rules.”
People can use mulching to fix the aesthetic problem of leaving leaves on the lawn. According to Rebecca Finneran of Michigan State University who received a Bachelor of Science in Horticulture with emphasis in Landscape Design, shortly after mowing the lawn the small pieces of leaves will disappear into the grass.
Felder Rushing, a 10th-generation American gardener, wrote for the Home and Garden Television (HGTV) – a U.S. cable and satellite television channel – that leaves do not have to be raked entirely. People can instead spread a thin layer of cut up leaves over the lawn which will act as an organic fertiliser, providing nourishment for the lawn.
