We have experienced our first few killing frosts of fall and deciduous trees, such as oaks, ash, hickory, etc., have been dropping their leaves profusely. While leaves can become excellent mulch or compost, they should not be left intact on your lawn. Leaves lying on the turf canopy reduce light and air circulation necessary for healthy turf. With a layer of leaves covering the lawn damage from diseases and insects can easily go unnoticed until the turf is totally destroyed. A blanket of leaves covering the turf will trap moisture between the soil and the leaves providing an ideal environment for the proliferation of pathogens such as large patch (rhizoctonia solani) and other diseases most prominent with the moderate temperatures of fall. Therefore, leaves should be periodically raked from the lawn or at least mulched down into the thatch with a good mulching mower.
While a good pair of soft work gloves, a nice large lawn rake, and a lightweight tarp are ideal tools to get leaves off the lawn, leaf blowers and bagging mowers can make the work go a lot faster and much easier. However, with these modern machines you don’t quite get the full benefits of great exercise and sore muscles to reward you from this chore.
