1. Boost Azaleas
After mowing the lawn, lay some of the grass clippings out to dry. Then spread a thin layer of clippings around the base of azalea plants. As the grass decays it leaches nitrogen into the soil, supplementing regular feeds. Many gardeners find this ‘something extra’ speeds the growth of azaleas and darkens the leaves. Be careful, though: piling the grass clippings too thickly may make them slimy and, in turn, expose the plant’s stems to disease.
