What is composting important for in horticulture?

Composting is vital in horticulture primarily because it enriches the soil and promotes overall plant health. This process involves the decomposition of organic materials, such as kitchen scraps and garden waste, which results in a nutrient-rich amendment known as compost.

The addition of compost to the soil enhances nutrient availability, improves soil structure, and increases microbial activity. These factors contribute to better water retention and drainage, which are crucial for healthy root development and the overall vitality of plants. Additionally, compost supplies essential nutrients in a slow-releasing form, which helps sustain plant growth over time.

While preventing pests, enhancing growth speed, and adding visual appeal to the soil can all be beneficial aspects of healthy horticultural practices, they are typically secondary effects rather than the primary purpose of composting itself. The core benefit lies in the nutritional and structural improvements to the soil, which is essential for thriving plant ecosystems.
