What is one result of improper plant selection in landscape architecture?

Improper plant selection in landscape architecture can lead to higher maintenance costs because the chosen plants may not be well-suited to the local climate, soil conditions, or overall environment. Plants that are not optimal for a specific site may require more frequent watering, fertilization, pest management, and pruning to thrive. This additional care can significantly increase both time and financial resources spent on maintaining the landscape. Well-selected plants, on the other hand, are more likely to establish successfully and thrive with minimal intervention, promoting a more sustainable and cost-effective landscape design.
