Which practice should be prioritized as part of sustainable landscaping according to FNGLA?

Prioritizing water conservation techniques is fundamental to sustainable landscaping because these practices address the essential need to utilize water efficiently, thereby preserving this vital natural resource. Sustainable landscaping aims to create a balance between maintaining aesthetic landscapes and protecting the environment. By implementing water conservation techniques, landscapers can significantly reduce water waste, enhance the resilience of plants, and ensure healthy ecosystems.

Techniques may include installing drip irrigation systems, using drought-resistant plants, mulching to retain soil moisture, and utilizing rainwater harvesting. These methods not only lower water usage but also promote biodiversity, improve soil health, and result in lower maintenance costs over time.

In contrast, using chemical fertilizers exclusively can lead to soil degradation and water pollution, while high-frequency watering might encourage shallow root systems and increase evaporation losses. Planting exotic species only can disrupt local ecosystems and negatively impact native flora and fauna. Thus, focusing on water conservation aligns perfectly with the principles of sustainability in landscaping.
