Best Cedar Hedge Fertilizer
Fertilizing a cedar hedge should be done using at least three essential minerals for their health: phosphorus, nitrogen, and potassium. In the first two years after planting, phosphorus aids in root development and root growth while improving disease resistance. Orange or red spots on foliage indicate phosphorus deficiency.
Nitrogen is necessary for the development of stems and foliage of adult cedars. Pale green or yellowish foliage is a sign of nitrogen deficiency. Underdeveloped cedar can also be another sign of nitrogen deficiency, which is responsible for protein production.
As for potassium, it strengthens your cedars and makes them vigorous and resistant. However, too much potassium should not be given to avoid blocking nitrogen assimilation. Fertilizing your hedge soil with a blend of essential minerals (also including iron, magnesium, and sulfur) is an excellent treatment for your cedars.
