Which of the following is the primary purpose of granular fertilizer for trees?

1. To attract pests

2. To prevent drought

3. To enhance growth

4. To provide shade

The correct answer is: To enhance growth

The primary purpose of granular fertilizer for trees is to enhance growth. Granular fertilizers contain essential nutrients, such as nitrogen, phosphorus, and potassium, which trees need for various physiological functions. These nutrients support critical processes like photosynthesis, root development, and overall biomass increase. When applied appropriately, granular fertilizers release nutrients gradually, making them available to the tree's root system over an extended period. This method of fertilization is particularly effective for promoting strong, healthy growth and improving the tree's resistance to diseases and environmental stressors. While attracting pests, preventing drought, and providing shade are relevant aspects of tree care, they do not represent the main goal of fertilization. Attracting pests can actually harm the tree's health, while preventing drought is more related to irrigation and water management practices. Providing shade is a benefit of healthy trees but is not the primary purpose of using granular fertilizer. The focus on enhancing growth highlights its importance in supporting the tree's health and vitality.
