This excerpt from "Notes on Gardening (Part 677): Optimizing potting mix from local materials for cost saving" offers guidance on optimising garden substrate creation by sourcing local ingredients to reduce expenses, particularly for professional growers or dedicated hobbyists. The author, Ang, suggests that while commercial mixes are high-quality, mixing one's own potting medium is more economical when purchasing materials in bulk. The text highlights several key components found in most formulated potting mixes, including garden soil, rice husk, red soil, and coco coir, which improve drainage, aeration, and water retention. By using these readily available materials, especially rice husk as an alternative to perlite and red soil for its iron content, nurseries can maximise profits due to lower transportation and material costs. The author concludes by recommending the addition of a slow-release fertiliser to the final homemade blend, even though a basic mix is suitable for general-purpose use.
