How do soil, drainage, sunlight, temperature, and pests affect plant selection?

In garden and landscape design, environmental requirements are fundamental to the selection, arrangement, and maintenance of plants. These factors dictate which species will thrive in a specific location:1

• Soil and Drainage: Soil properties determine a plant's ability to access nutrients and oxygen. Proper drainage is essential, as plants forced to absorb excess water may suffer from root drowning. Designers must assess soil composition—such as clay versus sand content—to determine if the site requires surface or subsurface drainage systems to ensure plant health.23
• Sunlight: Plants are selected based on their specific light requirements, ranging from full sun to shade.1
• Temperature: Plant hardiness zones are used to select species capable of surviving local temperature extremes, particularly minimum winter temperatures. In temperate zones, many plants rely on a winter resting period to survive.45
• Pests: Designers consider a plant's susceptibility to pests and diseases. Effective management involves choosing resistant varieties, practicing good garden hygiene, and ensuring proper air circulation through pruning to prevent outbreaks.16
