Sample CH - Certified Horticulturist Practice Questions

Try these questions from our free CH - Certified Horticulturist practice tests. The correct answer and an explanation follow each question.

  1. A soil test reports low potassium. Which symptom would you most likely observe on affected plants?

    • A. Purple discoloration of young leaves
    • B. Brown scorching along leaf margins of older leaves
    • C. Pale green color of entire plant
    • D. Stunted root growth only

Answer: B. Brown scorching along leaf margins of older leaves

Potassium deficiency typically causes marginal scorch (brown edges) on older, lower leaves because potassium is mobile and redistributed to younger tissue.

  • A distribution uniformity (DU) test for a sprinkler system measures:

    • A. Soil moisture at various depths
    • B. How evenly water is applied across the irrigated area
    • C. Water pressure at each head
    • D. Flow rate from each emitter
  • Answer: B. How evenly water is applied across the irrigated area

    DU compares catch-can volumes across the irrigated zone to determine how uniformly water is distributed; low DU indicates dry spots requiring over-irrigation elsewhere.

  • What is the primary sign of powdery mildew infection?

    • A. Water-soaked lesions on leaves
    • B. White, powdery coating on leaves
    • C. Brown or black leaf spots with yellow halos
    • D. Webbing on plant stems and leaves
  • Answer: B. White, powdery coating on leaves

    Powdery mildew is a common fungal disease easily identified by its distinctive appearance on plants. The primary sign of infection is a white or grayish powdery coating that forms on the surface of leaves, stems, and sometimes flowers and fruits. This powdery substance is composed of fungal spores and mycelia, making it a clear diagnostic symptom.

  • Soil compaction during landscape installation is best prevented by:

    • A. Watering soil heavily before equipment use
    • B. Restricting heavy equipment to designated access routes and protecting root zones
    • C. Rototilling compacted areas after installation
    • D. Adding sand to clay soils
  • Answer: B. Restricting heavy equipment to designated access routes and protecting root zones

    Limiting equipment access to designated lanes and placing matting over root zones prevents compaction of soil pores, preserving aeration and drainage around plants.
