Completing the certificate in Advanced Horticultural through AG IDEA was a valuable and motivating experience. As a property manager and landscape designer, the diverse coursework required by the certificate was immediately applicable to my daily work decisions. In addition, I was exposed to a deepening of knowledge that allowed me to incorporate new management programs and horticultural practices that will develop over the seasons to follow. This is important, because as landscapes change and grow, so too should our knowledge of work in horticulture fields evolve. The AG IDEA certificate program helped me greatly in this regard.
