What is a common technique to promote sustainable landscaping practices?

Utilizing compost and organic fertilizers to enrich soil is a fundamental practice in promoting sustainable landscaping. This technique enhances soil health by adding nutrients naturally, improving soil structure, and supporting microbiological activity. Organic compost acts as a natural fertilizer, releasing nutrients slowly and reducing the need for chemical fertilizers, which can leach into water systems and cause pollution. By enriching the soil, plants can thrive, resulting in a more resilient landscape that requires less water and is better equipped to withstand pests and diseases. This practice exemplifies sustainable landscaping as it not only supports the health of the plants but also contributes to the environmental well-being of the surrounding ecosystem.

Other options such as conventional plowing, paving garden spaces, and reducing plant density do not align with sustainable practices and can have detrimental effects on the environment, such as soil erosion, water runoff, and loss of biodiversity.
