Fall Fertilization of Evergreens

Fertilization can be important for healthy growth of landscape evergreens. Trees and shrubs in a landscape setting often do not have access to the nutrients that wild trees do. But timing is an important consideration; a poorly-timed application of fertilizer can cause problems for your plants.

  1. Timing

    • The University of Minnesota recommends fertilizing evergreen trees and shrubs in early spring or late fall. If you choose to fertilize in fall, be sure to wait until late in the season after evergreens go dormant.

    Considerations

    • Fertilizing too early in the fall can cause new growth that will not be not hardy enough to withstand the upcoming winter. This is less of a problem for southern growers, but if you live in an area where winters are warm, it is best to wait until spring anyway to avoid damaging your trees.

    Tips

    • Evergreens do not always need fertilization, especially if they are healthy, adult trees. Plants that need fertilizer will give signs such as stunted growth or off-color needles. If you plant an evergreen in fall, do not fertilize it until the following spring.
