Why Fertilize Trees and shrubs? Most of the plantings in our local landscape are not native to our area. Those that are, such as evergreens, are living in an environment very different than their natural setting. Fertilizing your ornamental trees and shrubs will make a huge difference in the appearance and vigor of your landscape. When granular feeding is done in the fall, your evergreens will be a healthier color, your fruit trees will produce more fruit, and flowering shrubs will flower with more blossoms! In nature, trees and shrubs rely on the leaves, pine needles and compost to provide nutrients. As homeowners, we normally rake up and remove this compost, leaving our plants no source of food. A quality feeding will replace this much needed void and help to keep all of your plants strong and healthy.
