Proper tree care is essential for promoting healthier trees and ensuring their longevity. Through practices such as appropriate pruning, pest management, proper watering, and nutrient management, trees can thrive in their environments. Healthy trees are more resilient to environmental stressors, diseases, and pests. They can also enhance the ecosystem by providing shade, improving air quality, and supporting wildlife.

The first option suggests that proper tree care ensures trees grow faster than their natural rate, which is not a realistic expectation as tree growth rates are influenced by genetics, species, and environmental conditions. Similarly, making trees immune to all diseases is an idealistic claim; while good care can reduce susceptibility, it cannot eliminate all diseases. Lastly, proper tree care does not inherently reduce the need for soil testing; in fact, understanding soil conditions is often a critical part of ensuring that trees receive the appropriate care they need to thrive. Therefore, promoting healthier trees and longevity is the most accurate representation of the benefits of proper tree care.
