Red Seal Landscape Horticulturist Practice Exam 2025 – Complete Test Prep

Composting green waste is a highly effective practice for reducing landscape waste as it involves the natural process of decomposing organic materials, such as plant clippings, leaves, and other garden debris, into nutrient-rich compost. This process not only minimizes the volume of waste that would otherwise be discarded but also enhances soil health by returning valuable nutrients to the earth. By converting organic waste into compost, landscape horticulturists can improve soil structure, support plant growth, and reduce the need for chemical fertilizers.

In contrast, other options do not contribute to waste reduction effectively. Burning fallen leaves contributes to air pollution and wastefulness of organic materials, while using non-biodegradable materials contributes to long-term waste accumulation in landfills. Discarding plant residues in landfills exacerbates waste issues, as these materials could otherwise be repurposed through composting or mulching. Thus, composting green waste stands out as a sustainable solution for landscape maintenance that aligns with waste reduction goals.
