1. Site constraints: The landscape design must be adapted to the site conditions, such as topography, soil type, climate, and available resources. This requires careful planning and site assessment.
2. Water management: Water is a critical resource in sustainable landscape design, and managing it effectively is a challenge. This includes rainwater harvesting, greywater reuse, and effective irrigation systems.
3. Plant selection: Choosing the right plants for the site and climate is key to a sustainable landscape. Native plants, drought-tolerant species, and low-maintenance cultivars are preferred for their ability to thrive with minimal inputs.
4. Soil health: Soil is the foundation of any landscape, and promoting its health is critical to a sustainable design. This may require soil amendments, composting, and other strategies to improve soil structure, fertility, and water-holding capacity.
5. Maintenance: A sustainable landscape must be maintained with minimal inputs, which requires careful planning and design. This includes strategies such as integrated pest management, composting, and natural pruning techniques.
6. Community engagement: Sustainable landscape design must engage the community, including stakeholders and residents, to ensure the design meets their needs and reflects their values. This requires communication, education, and participation in the design process.
