Mow leaves into the lawn this fall and be rewarded with healthier soil for the lawn next spring. If you use a bag attached to the mower to catch the chopped leaves, spread those chopped leaves as a mulch around trees and shrubs, and also in your perennial beds. The leaf-grass mix can also be added to the vegetable garden or, of course, your compost pile. Healthy leaves in garden beds can be left in place now, or, if you are a neatnik, rake leaves off beds, chip them up by running over the leaves repeatedly with your mulching mower, and return them to the beds. They will return the nutrients to the soil over the winter. If you are into neither mowing nor raking, spread a layer of compost over the garden beds and let Mother Nature do all the work of breaking down your leaves.
