Leaves contain relatively large amounts of valuable elements, such as calcium and potassium. When they fall to the ground and decompose, they return to the soil part of the elements used to make the tree grow. At the same time, the layer of leaves forms a water-absorbing humus.
It is necessary to remove heavy accumulations of leaves. One of the easiest methods is to run over the lawn with a lawn mower with catcher attached. The shredded leaves will make an excellent mulch around trees and shrubs or can be mixed with other yard wastes in the compost pile where it will take up less space and decompose much faster than unshredded ones.
