What is the main purpose of fertilizers in floriculture?

The main purpose of fertilizers in floriculture is to provide essential nutrients for plant growth. Plants require a variety of nutrients to thrive, including macronutrients like nitrogen, phosphorus, and potassium, as well as micronutrients such as iron, manganese, and zinc. These nutrients play critical roles in various physiological functions, including photosynthesis, energy transfer, and overall development.

While enhancing the aesthetic appearance of plants may be a desired outcome of proper fertilization, it is not the primary function of fertilizers. Instead, the focus is on supplying the nutrients that allow plants to grow healthily and robustly, which in turn can lead to better blooming and improved overall appearance.

Although preventing plant diseases and pests is crucial in blooming and maintaining plant health, fertilizers specifically do not serve as direct disease or pest control agents. Similarly, regulating soil pH levels is important in horticulture, but pH regulation is typically achieved through other amendments rather than fertilizers. Therefore, the correct answer highlights the essential role of fertilizers in providing the nutrients needed for successful floriculture.
