Nutrient Deficiency
All plants need nutrients and can benefit from a regularly scheduled fertilization treatment. Ask a professional to analyze your trees and shrubs for a nutrient deficiency if you see these signs:
a slow rate and low amount of annual growth on twigs and trunk,
smaller than normal foliage,
off-color foliage,
increased amounts of dead branches,
tip-die back in branches,
and increased rates of disease and insect problems.
