Yes, grasses used for lawns might be smothered by excess leaves, but it’s much better to mow right over them to create mulch than to blow them away. The resulting shredded leaves will settle in to the grass providing nutrients and reducing the need for fertilizers, weed killers and insecticides. Mow mulching is a simple affordable alternative for the use of leaf blowers. Leaf mulching requires more strength from your mower, so not all mowers are suitable for leaf mulching, but most regular mowers will do. When fall arrives switch to mulching blades and make sure your mower deck’s exit chute is closed, so that the leaves stay in the deck for another rotation so they get chopped into smaller pieces. Leaf mulching on lawns has many advantages. Mulched leaves will add nutrients to the soil, and create a better soil structure. Sometimes the mulching takes a little longer than regular mowing, and with a thick layer of leaves you might need to mow more often. But the lawn will be healthier and won’t need as much fertilizer or water. Discuss this practice with the yard owner. If there are many trees on the property, more labor might be required. Try to mitigate the labor costs with the savings on fertilizer or hauling costs, or maybe even suggest a size reduction of the lawn.
