What is the role of Plant Health Care (PHC) in landscape maintenance?

• A. PHC focuses only on chemical control of pests.
• B. PHC emphasizes proactive cultural practices to maintain vigor, prevent pests and diseases, and apply targeted treatments when needed.
• C. PHC is about irrigation scheduling.
• D. PHC replaces the need for pest management.

Answer: (B)

Plant Health Care is about keeping landscape plants healthy by preventing problems before they start and supporting their vigor. It emphasizes proactive cultural practices—selecting appropriate plants for the site, improving soil and drainage, proper irrigation to avoid stress, mulching, timely fertilization, and pruning that maintains structure and airflow—to help plants resist pests and diseases. When issues do arise, treatments are targeted and used only as needed, after monitoring confirms a problem, which reduces unnecessary chemical use. This approach is broader than just chemical control or irrigation scheduling, and it doesn’t replace pest management; it integrates ongoing plant care with selective interventions to maintain overall plant health.
