What “Compost” Really Means in Malta

When you search for compost in Malta, you probably expect one thing: a natural material that improves soil, feeds plants, and supports long-term growth.
But here’s the reality, many products sold as “compost” are not actually compost in the traditional sense.
In fact, a large portion of products found under “compost” categories in Malta are peat-based potting mixes, coconut substrates, or general growing media. These can still be useful, but they serve a completely different purpose.
Understanding this difference is one of the most important steps you can take as a grower.
Why Most “Compost” Products Are Not What You Think
Many retail products labelled as compost are designed for convenience, not soil regeneration.
These products often include:
Peat-based blends
Coco coir substrates
Fertilised potting soils
Lightweight growing media
They are primarily made to:
Hold moisture
Support roots in pots
Provide short-term nutrient availability
But they are not always designed to build soil over time.
That doesn’t make them bad, it just means they are often misunderstood.

Compost vs Potting Mix: The Key Difference
It’s easy to confuse the two, but they serve very different roles.
Compost
Fully decomposed organic matter
Rich in humified carbon
Supports microbial life
Improves soil structure long-term
Used to build and regenerate soil
Potting Mix
Engineered growing medium
Designed for containers
Focused on water retention and aeration
Often peat or coco-based
Used for plant support, not soil building
If your goal is healthy soil, resilience, and long-term fertility, compost is the foundation.
Why This Matters for Malta’s Soil
Malta presents unique growing challenges:
Low organic matter soils
Fast drainage and water loss
High summer temperatures
Soil fatigue from repeated use
In these conditions, simply using potting mixes is not enough.
To build strong, resilient growing systems, you need materials that:
Increase organic matter
Improve water retention naturally
Support beneficial microorganisms
Stabilise soil structure
This is where real compost becomes essential.
What Real Compost Looks Like
A genuine composted soil improver has clear characteristics:
Dark brown, soil-like appearance
Rich, earthy smell (like forest soil)
Stable, mature organic matter
Biologically active and balanced
Produced through composting and curing
For example, properly composted materials are created through controlled decomposition, turning, and fermentation processes over time, resulting in a stable and plant-friendly product.
Our ACV Green Composted Soil Improver follows this type of process and is suitable for organic agriculture, providing humified organic matter that supports soil life and root development.
How to Choose the Right Compost
Before buying any product labelled as compost, ask yourself:
Is it a peat-based mix or real compost?
Does it mention composting or just blending?
Are there technical values (organic carbon, C/N ratio, etc.)?
Is it suitable for organic agriculture?
Is it designed to improve soil or just grow plants in pots?
These simple checks can help you avoid confusion and choose the right material for your goals.
A Better Way to Think About Soil
At TerraSoil, we believe growing starts with the soil, not just the plant.
That means:
Feeding the soil ecosystem
Supporting microbial life
Building structure and stability
Creating long-term fertility
Compost is not just another input, it’s one of the most important building blocks in any organic or regenerative system.
Final Thoughts
Not all compost is the same and in Malta, the term is often used very loosely.
Many products sold as compost are actually growing media designed for pots and short-term use. That’s fine if that’s what you need.
But if your goal is to improve soil, increase resilience, and grow better over time, then choosing a real composted soil improver makes all the difference.
FAQ
Is compost the same as potting soil?
No. Compost improves soil health and biology, while potting soil is designed mainly to support plants in containers.
Can I use peat compost to improve soil?
Peat-based mixes can help short-term, but they are not as effective as real compost for long-term soil improvement.
What is the best compost for Malta soil?
A mature, biologically active compost with stable organic matter is best suited for Malta’s dry and low-organic soils.
