Pozzolan 20 L: Sustainable Volcanic Mulch for Dry & Solid Garden

The Pozzolan bag (20 L) is the mineral and rot-proof mulching solution from volcanic rocks. Thanks to its 7/12 mm calibration and UAB approval, it is ideal for sustainable gardening. It acts as an excellent thermal insulator to protect roots and limit watering by reducing evaporation, while also forming a physical barrier that reduces weeding. Ready to use, it can be used in layers of 4 cm for flower beds and up to 10 cm for dry gardens (ideally on geotextile film). It is also a great drainage material for your pots and planters. Choosing pozzolan means opting for a perennial, clean and effective mulch all year round for a garden requiring less maintenance.
