Practicing Professional Horticulturist (PPH) Soil pH management and nutrient cycling form the technical foundation you’ll need solid grounding in before taking PPH. Candidates who’ve worked with perennials, annuals, or turf systems grasp the exam faster, but even experienced growers sometimes miss the depth of integrated pest management protocols and landscape design principles the exam covers. Prerequisite knowledge of USDA hardiness zones and plant propagation methods helps considerably.
