Or Brun Pumice Stone Mulch 20L | Slug Barrier & Pot Drainage

The Or Brun Pumice Stone Mulch 20L (Reference: OBRPPOU20) is a mineral amendment of volcanic origin essential for enhancing and protecting your crops in pots, containers and planters. 100% natural and ecological, this porous and inalterable rock constitutes a permanent mulch solution that does not degrade over the seasons. Ideal for urban gardeners as well as outdoor space enthusiasts, it creates a stable and secure environment for the harmonious development of all your plants.

Natural barrier against slugs and thermal insulation

On the surface, the rough and abrasive texture of pumice stone acts as a formidable physical barrier against slug and snail invasion, thus preserving the integrity of your young shoots and plantations without any recourse to chemical products. Beyond this defensive mechanical action, it effectively insulates the root system from brutal temperature variations. It stores heat during the day to release it at night, protecting your crops from winter frost and summer heat waves.

Dual action: Perfect drainage and moisture management

This versatile mineral substrate fulfills two complementary functions essential for proper water management within your containers. Placed at the bottom of pots in a 2 to 3 cm layer, it optimizes drainage and improves aeration, prevents water stagnation and prevents root asphyxiation. Used on the surface in a 3 to 4 cm layer, it significantly reduces natural evaporation, maintaining constant freshness in the soil while reducing the frequency of your watering.

Simplified weeding and decorative mineral aesthetics

The installation is easy and drastically limits weed development by blocking the light necessary for weed seed germination, thus lightening the weeding chore. Aesthetically, its natural brown color and raw texture bring an impeccable contemporary mineral touch. It beautifully enhances the greenery of your houseplants, balcony flower compositions or vegetable gardens while maintaining the cleanliness of your outdoor spaces.

Certified quality and respect for Organic Agriculture

Compliant with the strict requirements of quality standard NF U 44-551, this mineral growing medium is entirely usable in Organic Agriculture (UAB). Its porous and rot-proof structure guarantees exceptional durability, unlike organic mulches that require annual replenishment due to decomposition. Not acidifying the soil, its total chemical neutrality makes it perfectly compatible with most flowering plants, shrubs and ornamental vegetables.
