Composting Mastery: Bins, Ingredients, and Methods for Black Gold

Composting is gardening's highest-ROI habit: free fertilizer, waste recycling, soil transformation. Choose your system and feed it right.

Bin Options

• DIY chicken wire cylinder: Simple but leaks fines, loses heat.
• Reclaimed timber boxes (2–3 bays): One "cooking" while others fill. Carpet lid retains heat; slotted front boards ease turning.
• Self-turning dual-bin: Small can inside large. Layer brown (shredded paper/cardboard) + soil + green (veg waste). Drill drainage holes. Shake inner bin 2×/month—no fork needed.
• Microbe composter (Bokashi): Indoor, microbe-accelerated, no heat.
• Wormery: Earthworms process kitchen waste → castings.
• Robotic composter: Auto heat/mix. 5 lbs/day including meat/dairy/fish. High upfront + energy cost.

What to Compost (and Avoid)

Yes: Garden green waste (no pernicious weeds/diseased material—burn those), kitchen veg/fruit waste. Mix browns + greens. Shredded newspaper layers prevent slime. Aged horse manure enriches (never fresh—too acidic).
No: Meat/fish/dairy (conventional systems), diseased plants, invasive weeds.

Sweet, dark compost = dramatically better flowers and yields. Worth every turn.
