I talk to my patients about the analogies of life and plants. It is no coincidence that these comparisons are so easily followed and applicable in our day to day lives. People understand too much of a good thing rule... too much water, too much fertilizer, too much sun (and not enough sleep or darkness), and too much wind (versus no air circulation/stagnancy).
Horticulture Therapy is fertilization for woundedness. As a horticulture therapist, my goal is let the plants heal what is wounded by others.
