AP News - There are a lot of leaves outside my window, and I’m guessing your view might be similar. This carpet of dead foliage is often viewed as a nuisance, but it can be an important component in the garden.
I’ll push a 3-inch (7.6-centimeter) layer of them into beds and borders to serve as root-protecting and insect-sheltering winter mulch. When they decompose, they’ll also add nutrients to the soil, which will fortify my plants in spring.
Others will make it into the compost pile, which, along with food scraps, weeds and spent annuals and perennials, will cook into what we gardeners call “black gold.” But there’s another use for fallen leaves that might have escaped your notice: leaf mold.
Simpler than compost but similarly beneficial, leaf mold contains only one ingredient — leaves. It helps increase moisture retention in sandy soil, improve drainage in clay soil, regulate soil temperature and suppress weeds when applied over the soil in beds and borders.
As far as nutrients go, compost wins, but leaf mold is no slacker. It supports earthworms, beneficial insects and soil microbes, and boosts the health and vigor of plants
