Wormery vs. Compost Bin: Which is best for Gardeners?


Wormery vs. Compost Bin: Unraveling the Debate for Eco-Conscious Gardeners

In the realm of eco-friendly gardening practices, composting stands as a beacon of sustainability. But amidst the array of composting methods, two stand out as the frontrunners: wormeries and traditional compost bins. While both aim to transform organic waste into nutrient-rich soil amendments, they differ in their processes, outcomes, and suitability for various gardening scenarios.

Is a hot composter faster than worms?

Due to the increased heat allowed in a hot composter and without the need to keep worms alive at lower temperatures, a hot composter can be faster to decompose waste. 

What composter is best for dog poo?

Both will give you liquid you can dilute and feed to pot plants. Compost bins are good for creating soil you can use in the garden; worm farms can be used for cat and dog poo.

Is worm composting smelly?

Expect a good, earthy smell. It shouldn't smell much different than rich garden soil. You might expect worm waste to smell, but it simply isn't the case.

What are the top mistakes of having a worm farm?

  1. Mistake #1: Overfeeding
  2. Mistake #2: Too Wet or Too Dry Composting Bedding
  3. Mistake #3: Wrong Food
  4. Mistake #4: Too Hot or Too Cold
  5. Mistake #5: Forget to Harvest Worm Castings

How often do worms breed?

27 days from mating to laying eggs. Worms can double in population every 60 days.

Key differences of hot composters and wormeries?

  • Due to worms’ highly specialized digestive process, their waste contains bacteria and enzymes not present in compost. This is a more concentrated product of nitrogen, phosphorus, and potassium.
  • Worms can specialise in nutrients: 
    • Bacterial-dominant castings and compost are best-suited for annuals and grasses
    • Fungal-dominated castings and compost provide the most value to perennials and woody plants (e.g., trees and vines).


Wormeries: A Microcosm of Nature's Recycling Magic

At the heart of a wormery lies an army of tiny red wiggler worms, tirelessly devouring food scraps and other organic matter. These tireless workers break down organic matter into a rich, fertile compost called vermicompost. Unlike traditional compost bins that rely on heat and oxygen, wormeries thrive in a moist, neutral pH environment, making them ideal for indoor use or for those with limited space.

Benefits and Drawback of Wormeries.

Pros of Wormeries:

  • Compact and Space-Efficient: Wormeries are typically smaller and more manageable than traditional compost bins, making them suitable for apartment dwellers or those with limited outdoor space.
  • Faster Composting Cycle: Wormeries produce compost much quicker than traditional compost bins, often within a few months.
  • High-Quality Vermicompost: Vermicompost is considered to be of superior quality compared to traditional compost, containing higher levels of nutrients and beneficial microorganisms.
  • Less Odor: Wormeries generate minimal odor due to their controlled environment and the absence of odorous decomposition processes.

Cons of Wormeries:

  • More Demanding Maintenance: Wormeries require more frequent monitoring and adjustments to ensure optimal conditions for the worms.
  • Limited Waste Input: Wormeries can only process a certain amount of organic matter, making them unsuitable for large amounts of food scraps or yard waste.
  • More Sensitive to Environmental Factors: Wormeries are more susceptible to disruptions in temperature, moisture, and pH balance, which can affect worm activity and compost quality.

Traditional Compost Bins: A Versatile Composting Option

Traditional compost bins provide a larger and more versatile option for composting organic waste. They typically consist of open bins or tumblers, allowing for air circulation and natural decomposition by microorganisms. These bins can handle a wider range of organic materials, including yard waste, food scraps, and even some non-organic items like shredded paper.

Benefits and Drawback of Composters

Pros of Traditional Compost Bins:

  • Handles Larger Volumes: Traditional compost bins can accommodate larger volumes of organic waste, making them suitable for households with more food scraps or yard waste.
  • Versatile Material Breakdown: Traditional compost bins can break down a wider range of organic materials, including yard waste, food scraps, and some non-organic items.
  • Less Maintenance: Traditional compost bins require less frequent monitoring and adjustments than wormeries.
  • Nourishes Beneficial Microorganisms: Traditional compost bins provide a habitat for beneficial microorganisms that play a crucial role in nutrient cycling.

Cons of Traditional Compost Bins:

  • Slower Composting Cycle: Traditional compost bins typically take longer to produce finished compost, often around 1-2 years.
  • Odour Emissions: During the composting process, traditional compost bins may emit some odor, especially in the initial stages.
  • Larger Footprint: Traditional compost bins occupy more space, making them less suitable for small gardens or limited outdoor areas.

Choosing what's best for you, worms or no worms?

The choice between a wormery and a traditional compost bin depends on individual needs and preferences. For those seeking a compact and space-saving solution with faster compost production and high-quality vermicompost, a wormery is an excellent choice. However, for those with larger quantities of organic waste, a traditional compost bin offers a more versatile and robust composting option. Ultimately, the best choice aligns with the individual's composting goals, available space, and lifestyle factors.

Whether you opt for a wormery or a traditional compost bin, both methods contribute to sustainable gardening practices, reducing household waste, and enriching soil health. By embracing these eco-friendly techniques, gardeners can foster a harmonious relationship with nature while cultivating thriving gardens.
