When to Fertilize

Trees and shrubs growing in their natural habitat survive very well without supplemental fertilization. Leaves, needles and fallen branches decompose on the ground and recycle nutrients. In the urban environment, landscapes are kept neat, and leaves and branches are removed. Soil is packed by human and vehicular traffic. Buildings often reflect heat, creating additional stress…
