The arborvitae is an evergreen tree that is found over many parts of eastern Canada and the northeastern United States. It is a member of the cypress family and has soft scale-like leaves. This tree doesn't like hot, humid climates and actually prefers cool summers. Like all plants, proper fertilization is key to achieving a healthy looking evergreen. Miracle-Gro Evergreen Fertilizer Spikes are an effective method of fertilizing arborvitaes because they only have to be applied twice per year and deliver a constant slow-release fertilizer to your tree.
Water the entire root zone of the arborvitae until the soil is moist. The root zone will extend from the trunk outward to the edge of the outermost branches.
Place the provided plastic cap on top of a fertilizer spike and drive it into the ground with a hammer at the edge of the drip line (outermost branches). Remove the plastic cap and hammer the spike until it's 2 inches below the soil surface.
Repeat the above process and drive Miracle-Gro fertilizer spikes into the ground around the entire drip line at a distance of 3 feet apart.
Apply the spikes twice each year--once in the early spring and once in mid-fall.
