What is a major focus of horticultural practices?

The major focus of horticultural practices centers around the cultivation and management of plants for food, beauty, and functionality. This encompasses a wide range of activities including growing fruits and vegetables for consumption, developing ornamental plants for landscaping and aesthetic appeal, and utilizing plants in functional applications such as erosion control and environmental mitigation. Horticulture emphasizes not just the biological aspects of plant growth, but also the art and science behind creating sustainable, productive landscapes that enhance both human experience and the environment.

While other choices like creating artificial landscapes or the industrial production of flowers reflect aspects of horticulture, they represent narrower applications rather than the broader, holistic focus of horticulture. Studying plant diseases is an important area within horticulture but is primarily concerned with plant health rather than the overall cultivation and multifunctional use of plants. Thus, the correct answer encapsulates the comprehensive nature of horticultural practices in enhancing human life through plant management.
