What to Put in a Compost Heap and How to Maintain It

A compost heap is a great way to turn kitchen scraps and yard waste into a nutrient-rich soil amendment for your garden. It's easy to set up and maintain, and it's a great way to reduce waste and create a sustainable gardening practice.

To start, you'll want to add a mix of "green" and "brown" materials to your compost heap. Green materials like food scraps, grass clippings, and fresh leaves are high in nitrogen, while brown materials like dried leaves, twigs, and shredded newspaper are high in carbon. Aim for a mix of 2/3 brown materials and 1/3 green materials.

This balance of green and brown materials will help your compost heap break down quickly and efficiently. If you add too many green materials, your compost heap may become too wet and smelly. On the other hand, if you add too many brown materials, your compost heap may not break down at all.

As you add materials to your compost heap, be sure to turn it regularly to keep everything aerated and breaking down. You can use a pitchfork or shovel to turn the compost heap every few days, or you can use a compost turner tool for easier turning.

Composting is a way to help food trash and other organic items decompose into a substance that can be used to alter the composition of soil so that it's more nutritious for plants.

The composting process starts with adding certain bacteria activators to the organic material to create heat.

Heat is what causes the organic material to decompose more quickly than it would in nature.

This process is a natural and efficient way to turn waste into a valuable resource for gardening and agriculture.

Setting up a compost heap is a straightforward process, but it's essential to do it right to get the best results.

You can build a compost heap in your garden to process large amounts of waste.

To create a compost heap, you'll need to have a space that's at least one cubic metre in volume.

This allows for the necessary green and brown layers, which will enable 'hot composting' to occur.

Hot composting builds up heat through biological processes, accelerating the composting process and even killing weed seeds.

Just be sure to contain your compost heap in a rodent-proof structure, as using it for food scraps can attract unwanted pests.

Compostable items are a crucial part of a thriving compost heap. You can add a variety of materials to your compost bin, including egg cartons, hair and nail clippings, old natural fibre fabrics, and brown cardboard.

Some items to consider adding to your compost bin include 'Greens' (nitrogen-rich ingredients) such as grass cuttings, young weeds, and nettles, as well as 'Browns' (carbon-rich ingredients) like cardboard, waste paper, and bedding from vegetarian pets. You can also add urine, but ideally it should be diluted 20:1.

Some other compostable items include wood ash, in moderation, hair, nail clippings, and egg shells.

Composting is all about balance, and the golden rule is to have at least 50% brown materials. Brown materials are old, dry stuff like dead leaves, wood chips, straw, and plain brown cardboard.

Autumn leaves are an abundant and free source of brown material. They're a great addition to your compost bin.

To achieve the right balance, you'll want to mix in a variety of materials. Here are some examples of 'greens' and 'browns' you can add to your compost bin:

Cutting up big stems and crushing eggshells can help your compost break down more quickly. This will give your compost a helping hand and make the process more efficient.

Composting can be a breeze, and it's amazing what you can add to your compost bin. Egg cartons, for instance, are a great addition.

You can also compost hair and nail clippings, both from pets and humans. Old natural fibre fabrics like worn pure cotton or linen bed sheets can be composted, but be sure to cut them into small pieces and avoid seams with polyester thread.

Brown cardboard is another item that can be composted, as long as you remove any sticky tape or staples and tear it into pieces. Cardboard toilet rolls can also be added to your compost bin, just rip them up first.

Other items that can be composted include tissues and paper towel, cotton buds with wooden or paper stems, and shredded office paper. Even certified compostable packaging can be tried at home, although some may require commercial composting conditions.

Here are some examples of compostable items:

You can also add 'greens' and 'browns' to your compost bin. 'Greens' include grass cuttings, young weeds, nettles, comfrey leaves, and uncooked fruit and vegetable peelings. 'Browns' include cardboard, waste paper, junk mail, paper towels and bags, bedding from vegetarian pets, and tough hedge clippings.

Some other compostable items include wood ash, hair, nail clippings, egg shells, and natural fibres like wool and cotton.

When you're setting up your compost bin, it's easy to get excited and throw everything in there. But, some things are best left out. Animal products like meat, bones, and dairy should be avoided, unless you're sure they're fine in small amounts.

Fats and oils are also a no-go, as they can attract pests and create odors. And don't even think about adding plastic fruit stickers, rubber bands, or other produce labels – they're not compostable.

Some types of paper and cardboard are also off-limits, like glossy paper and cardboard with a coating. Treated timber or its sawdust should be kept out too, as they can harm microorganisms in the compost.

Diseased plants and weed seeds should be avoided, as they can spread disease and contaminate your compost. And, if you have pets, it's best to use a specialist worm farm or your council green waste bin for their poo.

Here's a quick rundown of what not to compost:

Compost heaps for large gardens can be built to compost significant amounts of garden waste. It's essential to create a structure that's at least one cubic metre in volume to allow for 'hot composting' to occur.

Biological processes in the heap build up heat, which accelerates the composting process and can even kill weed seeds. This is especially beneficial for gardens with weeds.

Unless your compost heap is contained in a rodent-proof structure, it's not suitable for food scraps, as it may attract unwanted guests.

Adding items to the compost heap is a crucial part of the process, and it's essential to know what can and can't be included. For 'greens', which are nitrogen-rich ingredients, consider adding grass cuttings, young weeds, nettles (not roots), comfrey leaves, and uncooked fruit and vegetable peelings.

You can also add 'browns', which are carbon-rich ingredients, such as cardboard, waste paper, junk mail, paper towels and bags, bedding from vegetarian pets, and tough hedge clippings. These items will help balance out the compost and create a healthy environment for the microorganisms to thrive.

Here's a list of some of the items you can add to your compost heap:

Keeping your compost heap damp is crucial for the health of the beneficial microbes and insects that break down the organic matter. In hot weather, you may need to add water to your compost to keep it damp.

The ideal moisture level for your compost is like a damp sponge - not soaking wet, but not dry either. This will help the microbes and insects thrive and do their job efficiently.

Adding items to the compost heap can be a fun and rewarding experience. It's amazing how quickly they break down into nutrient-rich soil for your garden.

To start, you'll want to add a mix of 'Greens' and 'Browns' to your compost bin. 'Greens' are nitrogen-rich ingredients like grass cuttings, young weeds, and comfrey leaves. These add a boost of energy to the composting process.

'Greens' can also include uncooked fruit and vegetable peelings, tea leaves, and coffee grounds. I like to add these to my compost bin after breakfast, it's a great way to reduce waste and create something useful.

On the other hand, 'Browns' are carbon-rich ingredients like cardboard, waste paper, and junk mail. These add structure and help balance out the 'Greens'.

Here are some specific items you can add to your compost bin:

You can also add other compostable items like wood ash, hair, nail clippings, and egg shells. Just be sure to add them in moderation, as too much can throw off the balance of your compost heap.
