What should be regularly monitored to maintain a healthy landscape?

Monitoring plant growth and pest activity is crucial for maintaining a healthy landscape because both factors directly impact the overall health and aesthetics of plants. Regular observation of plant growth allows for the early detection of any growth abnormalities, nutrient deficiencies, or environmental stresses. Additionally, monitoring pest activity is essential to identify any invasive species or outbreaks that could threaten the health of the plants. Addressing these issues promptly helps prevent more extensive damage and contributes to the proper management of the landscape.

Other variables like soil pH, pest signs, and fertilizer levels are important aspects of landscape management, but they do not encompass the full spectrum of what's required for holistic landscape health. By focusing exclusively on soil pH or fertilizer levels, one might miss signs of stress or pest infestations that could quickly escalate if left unchecked. Therefore, a comprehensive approach that includes both plant growth and pest activity offers a more effective strategy for maintaining a vibrant and resilient landscape.
