Which Composting Method is Best?

Posted by Catherine Wainwright, on March 15, 2024.

There are several methods of composting, which can generally be split into three categories: cold composting, hot composting, and vermicomposting. Cold composting is relatively low-maintenance and decomposes organic matter slowly over time. Hot composting is a more intensive process that accelerates decomposition, producing compost quickly. Vermicomposting uses worms to break down kitchen scraps. Each method has its advantages — the best method is the one that suits your needs, environment, volume of organic waste, and intended use.

Cold Composting

Cold composting is a passive method that involves layering or mixing organic materials like kitchen scraps and yard waste in a compost bin or pile. This method relies on natural decomposition processes over time. While it may take longer to produce finished compost, it is ideal for those seeking a low-maintenance approach or during colder months when temperatures are unsuitable for hot composting. Despite its slower pace, it effectively recycles organic waste into nutrient-rich compost with minimal effort required from the gardener.

Composting Bin

Composting bins are ideal for those seeking a low-maintenance method that looks tidy in the garden. At Garantia we have a range of compost bins to suit your gardening needs. Our composters are specifically designed to make composting hassle-free and efficient. With features like aeration vents and dual filling hatches, Garantia compost bins provide a controlled environment that protects your compost from rain and pests, ensuring optimal decomposition.

Garantia’s thermo range of compost bins are crafted from patented Thermolene plastic, setting them apart with innovative features designed to revolutionise your composting experience. This unique material is not only durable but also boasts exceptional thermal properties, regulating compost temperature to accelerate decomposition. This means you’ll enjoy efficient and faster composting, with minimal effort required on your part.

Simply add your kitchen scraps and garden waste as they accumulate, and let the bin do the rest. With minimal effort required, you can enjoy nutrient-rich compost to nourish your plants and enrich your garden soil.

Compost Heap

It is possible to simply pile organic material directly in the garden and allow it to slowly decompose. This method can take longer to yield mature compost than using a bin and may not look attractive in your garden. It is also worth considering that exposed compost heaps can attract pests, particularly if it includes kitchen scraps. During wet weather, protect your compost heap using cardboard, carpet, or polythene sheeting.

Hot Composting

Hot composting is a fast process that produces compost in several weeks. This method requires a large quantity of organic materials to begin the pile, encouraging microbial activity that generates heat. These high temperatures kill pathogens, weed seeds, and harmful bacteria. Hot composting piles or bins should be at least 1 metre squared and require regular turning, which can be tiresome work. This method is not suitable for those with small amounts of waste or limited space, but it is a great option for producing large quantities of high-quality compost in a short amount of time.

Vermicomposting

Vermicomposting uses worms to break down organic waste into a rich compost and a liquid fertiliser. Wormeries can either be shop-bought or homemade, with pre-made options often including stacked trays that make the compost easier to collect. Vermicomposting is relatively low-maintenance but requires attention to temperature, moisture, and quantities of kitchen scraps. Vermicomposting is ideal for those with limited space, as it can be done indoors or in small outdoor spaces.
