Horticulture is a broad field that encompasses the cultivation of a wide variety of plants, including:

* Fruits: Apples, oranges, strawberries, etc.

* Vegetables: Tomatoes, carrots, broccoli, etc.

* Ornamental plants: Flowers, shrubs, trees, etc.

* Herbs: Basil, rosemary, mint, etc.

Horticulture involves understanding the science behind plant growth, including:

* Soil science: The composition and properties of soil.

* Plant physiology: How plants grow and develop.

* Plant nutrition: The nutrients plants need and how to provide them.

* Pest and disease management: Identifying and controlling pests and diseases that affect plants.

* Irrigation: Providing water to plants in an efficient and effective way.

So, while you might hear people talk about "vegetable gardening" or "fruit growing", the overall science behind it all is horticulture.
