Composting 101: Turn Waste into Garden Gold

Composting is one of the simplest and most impactful things you can do for your garden. By turning kitchen scraps, fallen leaves, and garden clippings into rich humus, you create a free, nutrient-packed fertiliser that improves soil structure, retains moisture, and feeds beneficial microorganisms. Best of all, it reduces the waste going to landfill.

Start with a simple three-bin system or a single compost bin in a shady corner of your garden. The golden rule is to maintain a balance of green materials (nitrogen-rich) and brown materials (carbon-rich) at roughly a 1:2 ratio. Greens include vegetable scraps, coffee grounds, fresh grass clippings, and manure. Browns include dry leaves, cardboard, straw, and sawdust. Layer them alternately, keep the pile moist like a wrung-out sponge, and turn it every two to three weeks to speed up decomposition.

Within three to six months, you'll have dark, crumbly compost ready to mix into garden beds, potting mixes, or lawn top-dressing. Avoid adding meat, dairy, oily foods, or diseased plant material, as these attract pests and can introduce pathogens. In South Africa's warm climate, composting accelerates during summer, so you can expect faster results than in cooler regions.
