Name a sustainable practice that landscape contractors should consider.

Using native plants to reduce water usage is a sustainable practice that landscape contractors should consider because native plants are well adapted to the local climate and soil conditions. This adaptation means they typically require less water, fertilizers, and pesticides compared to non-native or exotic species. By incorporating these plants into landscapes, contractors can help promote biodiversity, improve soil health, and create habitats for local wildlife. Additionally, using native plants significantly reduces the need for irrigation, making them an environmentally friendly choice that can lower maintenance costs over time.

On the other hand, options involving synthetic fertilizers may contribute to soil degradation and water pollution. Installing decorative fountains could increase water usage unnecessarily and might not align with sustainable practices. Planting exotic species can lead to ecological imbalances and potential invasiveness, straying away from the principles of sustainability in landscaping. Thus, utilizing native plants is a responsible and effective method for promoting sustainability in landscape design.
