Many people assume composting comes to a halt during winter, especially when cold mornings and short days make the garden feel like it’s gone to sleep. But truthfully, winter is a great time to keep your compost ticking along if you know how.
Whether you’ve got a full compost heap or a small bin tucked behind the shed, Hobart’s cool, damp climate actually makes it possible to compost garden waste through the winter months. You just need to make a few adjustments. That includes understanding what to compost, how to layer materials properly, and how to insulate something our gardening services in Hobart can help with if you’re not sure where to begin.

It might feel like everything slows down in the colder months, and your compost pile does too. But composting doesn’t stop. The microbial life that breaks down your scraps just moves a bit slower when it’s cold.
That’s actually a good thing. It gives your compost more time to mature and balance itself out, producing a richer mix by the time spring rolls around. Plus, continuing your composting habit means less garden waste ends up in landfill. It’s good for your plants and the planet.
So whether you’re dealing with pruned branches, fallen leaves or veggie scraps, keeping them out of the bin and in the compost heap is still worth it, even in July.
Composting is a biological process. Microorganisms and insects break down organic material, turning it into crumbly, nutrient-rich compost. But in winter, those microbes slow down due to cooler temperatures. This means:
If your compost is too small or exposed, it may cool down completely and go nearly dormant. That doesn’t mean it’s not working, just that it’s working very slowly. With a few simple tweaks, you can keep things going just enough to avoid a complete stall.

Composting in winter uses the same basic principle: a balance of carbon-rich “browns” and nitrogen-rich “greens.” But what you add, and how you add it, makes a difference in colder months.
If you’re unsure what’s suitable, stick to simple kitchen and garden waste. And always chop larger items into smaller pieces to help the process along.
You don’t need fancy equipment or a science degree to keep compost going in winter. Just a little common sense and consistency.
The larger your compost pile, the more heat it can retain. A small bin might cool down fast, but a pile at least 1m x 1m x 1m will insulate itself enough to keep microbial life moving.
Layer greens and browns as you go. Top with a thick carbon layer (like straw or cardboard) to prevent smells and sogginess. If your bin has open sides, wrap it in cardboard, bubble wrap or an old rug to hold in warmth.
A compost lid or tarp keeps excess rain out and helps maintain a stable temperature. This is especially helpful in Hobart’s wetter winter months.
Unlike summer composting, winter piles don’t need constant turning. Turning can let out heat. Turn once every few weeks at most, just to mix things up and prevent compaction.
Cut the waste into smaller pieces before adding. This gives microbes more surface area to work on and helps materials decompose faster.
This pairs well with other sustainable garden practices that help your garden thrive even in colder months.
If you’re in a rental, townhouse or just don’t have room for a full compost bay, don’t worry. You can still compost effectively with these alternative methods:
Perfect for patios or even under the sink. Red wriggler worms eat food scraps and turn them into rich castings. Keep them insulated and out of the wind in winter.
Dig a small trench in your garden bed, drop in food scraps, and cover with soil. By spring, it will have broken down into plant-ready nutrients.
These sealed buckets use microbes to ferment food scraps quickly. They work indoors and are ideal for homes with little outdoor space.
These systems are compact, low-maintenance, and ideal for Hobart’s cooler months, especially if you want to avoid trekking into the yard on a rainy morning.
For more efficient gardening, these simple lawn tips can complement your composting routine too.
Even with the best intentions, compost can occasionally go off-track. Here’s what to look out for, and what to do about it.
Fix: Add insulation, more brown material, and cover it up. Don’t turn until it thaws slightly.
Fix: Mix in shredded newspaper, dry leaves or cardboard. Add layers to soak up the excess water.
Fix: Overly wet or nitrogen-heavy piles can stink. Add more carbon-rich materials and stir gently.
Fix: Bury food scraps in the middle and avoid meat or dairy. Cover exposed waste with straw or dry leaves.
These kinds of maintenance issues are also covered in our guide to hiring a professional gardener, especially when you don’t have the time to manage compost or garden waste yourself.
Come early spring, your compost might be ready to use or at least close. Here’s how to tell:
You can:
Got more compost than you need? Share with neighbours, or use it to top up raised beds. And if your pile still looks half-finished, just let it mature through early spring.
