Start Composting Without Mistakes

Avoid the 5 most common composting mistakes and learn step by step how to create your own humus – with scientifically proven knowledge from symbiosis technology.

Which 5 mistakes do composting beginners make most often?

Over 70% of composting beginners fail due to the same mistakes. Avoid these pitfalls and get started right.

1

Wrong Mixing Ratio

The most common mistake: too much green (nitrogen) and too little brown (carbon). The ideal C:N ratio is about 25-30:1. Always mix kitchen scraps with dry leaves, cardboard, or straw.

2

Too Wet or Too Dry

Compost needs moisture like a wrung-out sponge – moist but not dripping. Too much water displaces oxygen and leads to rot. Too dry stops the decomposition process.

3

Wrong Location

A composter in full sun dries out; in deep shade it lacks warmth. The ideal location is partially shaded, wind-protected, and on natural ground so earthworms can migrate in.

4

Impatience

Good compost takes time – depending on the method, 3 to 12 months. Hot composting speeds up the process but requires active management. Patience and regular turning are key.

5

Wrong Materials

Not everything belongs in the compost: meat, dairy products, and diseased plants attract pests or spread disease. Coated paper and treated wood have no place in compost either.

Step by Step: Composting Done Right

1

Choose Location

Select a partially shaded, wind-protected spot on natural ground. The composter should be easily accessible and at least 50 cm from the property boundary.

2

Layer the Base

Start with a 10-15 cm thick layer of coarse material like branches or wood chips. This ensures drainage and aeration from below.

3

Build Layers

Alternate nitrogen-rich materials (kitchen scraps, grass clippings) with carbon-rich materials (leaves, cardboard, straw). Each layer should be 5-10 cm thick.

4

Check Moisture

Regularly check moisture with the squeeze test: compress a handful of compost – a few drops of water should come out, but no more.

5

Turn and Harvest

Turn the compost every 4-6 weeks to introduce oxygen. After 6-12 months, the compost is ready: it smells like forest floor and has a crumbly, dark consistency.

What Type of Composter Are You?

Balcony Composter

Ideal for city dwellers with limited space. Worm bins or Bokashi buckets process kitchen scraps odorlessly and compactly – perfect for Berlin apartments.

Garden Compost

The classic for garden owners. An open compost pile or bin processes large amounts of garden and kitchen waste into valuable humus.

Thermal Composter

For the impatient: enclosed rapid composters generate higher temperatures and deliver finished compost in just 3-4 months – ideal for beginners.

Frequently Asked Questions About Composting

How long does it take for compost to be ready?
Depending on method and materials, it takes 3-12 months. Hot composting with regular turning delivers results in 3-4 months. Cold composting without active management takes 9-12 months.
Does compost smell?
Properly made compost smells like forest floor – pleasantly earthy. Unpleasant odors indicate a problem: usually too much moisture or too little carbon material. The solution: mix in dry material and turn it.
Can I compost in winter?
Yes! Decomposition slows down at low temperatures but does not stop completely. Thermal composters retain heat better. You can continue collecting kitchen scraps in winter – the process accelerates again in spring.
What should not go in the compost?
Avoid meat, fish, dairy products, diseased plants, weeds with seeds, treated wood, coated paper, and ash from treated wood. Citrus fruits and onion skins in small amounts are fine.
