A Beginner's Guide to Composting at Home
Composting is one of the simplest ways to cut household waste and feed your garden for free. But it's also one of the easiest things to get wrong — and getting it wrong doesn't just mean a bad smell. It can mean pest infestations, mould, and in some cases genuine safety hazards around your home. Here's what you need to know before you start, and what to do if something goes wrong.
Why Compost?
Composting turns kitchen scraps and garden waste into nutrient-rich soil. It reduces landfill waste, cuts your bin costs, and improves soil health without chemical fertiliser. Done right, it's low-maintenance. Done wrong, it becomes a problem fast.
Getting Started: The Basics
1. Choose your setup. A simple open pile, a closed bin, or a tumbler — pick based on space and how much waste you generate.
2. Balance your "greens" and "browns".
Greens: fruit and veg scraps, coffee grounds, grass clippings (nitrogen-rich)
Browns: dry leaves, cardboard, straw (carbon-rich)
Aim for roughly 1 part green to 2–3 parts brown.
3. Keep it moist, not wet. The pile should feel like a wrung-out sponge.
4. Turn it regularly. This adds oxygen and speeds up decomposition.
5. Know what NOT to compost. Meat, dairy, oils, pet waste, and diseased plants attract pests and disease — leave these out.
Common Issues Beginners Run Into
"My compost smells terrible." Usually caused by too much moisture or too many greens, creating anaerobic (airless) conditions. Add dry browns and turn the pile to introduce air.
"It's attracting rats, flies, or other pests." This is one of the most common — and most urgent — complaints. It's almost always caused by meat, dairy, or cooked food scraps in the pile, or an uncovered bin. Switch to a fully enclosed bin and remove any offending material immediately.
"Nothing is breaking down." Usually a browns overload, poor moisture, or a pile that's too small to generate heat. Add greens, water lightly, and turn.
"There's mould or white fuzz on the pile." Generally normal fungal activity, but if it's excessive it can indicate the pile is too dry or too undisturbed. Turn it and monitor.
"My tumbler bin has stopped turning smoothly or the mechanism feels stuck/damaged." Stop forcing it. Composting equipment with moving or mechanical parts can cause injury if forced or if a part fails under pressure. Don't attempt to dismantle or repair the unit yourself if it feels unsafe — get it looked at.
Safety Notes — Please Read
Never compost near electrical equipment or outdoor power sources unsupervised. If your setup uses an electric shredder, aerator, or powered tumbler, always disconnect it from power before clearing blockages or doing any maintenance. Damp organic matter and electrical components are a genuinely dangerous combination — if a cord, plug, or unit looks damaged, worn, or has been exposed to moisture, stop using it and have it checked by a qualified electrician before plugging it in again.
Never attempt to modify plumbing or drainage to manage compost liquid runoff yourself. Some people try to divert "compost tea" or excess liquid into household drains or greywater systems. This can cause blockages, contamination, or damage to your plumbing system. If you're dealing with liquid runoff or drainage issues related to your compost setup, speak to a professional rather than improvising a fix.
If a pest infestation, mechanical fault, or drainage problem escalates, don't try to solve it with a workaround. Some fixes people attempt online are genuinely unsafe. When in doubt, stop and get it assessed properly.
When to Call in Help
Most composting hiccups are minor and self-correcting. But if you're facing any of the following, don't wait:
A pest infestation that's spreading toward your home
A powered composting unit with electrical damage or a fault
Drainage or runoff issues affecting your property
Any setup that feels structurally or mechanically unsafe
This is not the time for a DIY fix found in a forum thread. Get it looked at properly, and get it looked at now.
