Combiosoil Underground Mini Composter 25 cm, Black

The practical underground composter COMBIOSOIL, 25 cm high, turns kitchen and garden scraps into nutrients right at the roots of your plants. Thanks to its perforated walls it ensures excellent aeration, fast odor-free composting, and easy access via the lid. Ideal for vegetable beds, herb spirals, and flower borders.

Efficient composting directly in the soil

Perforated walls allow airflow and the entry of earthworms, which speeds up the breakdown of bio-waste and naturally nourishes surrounding plants.

Easy filling and maintenance

The removable lid with a handle provides convenient access. Add kitchen scraps without disassembling the composter.

Durable, well-ventilated design

Sturdy plastic with ventilation slots is designed for long-term outdoor use and stable airflow without clogging.

The Combiosoil underground mini composter is a smart solution for localized soil enrichment. Install it directly in a bed, where soil microorganisms and earthworms gradually break down organic scraps. Side perforations ensure optimal airflow and direct nutrient release to plant roots.

Thanks to its compact 25 cm height and removable lid, handling and refilling are easy. The robust plastic resists moisture and weather, enabling year-round use without issues. Suitable for vegetable and fruit peels, coffee grounds, small plant waste, and crushed eggshells.
