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

Pozzolan Bag (20 L): Sustainable and Natural Mulching for Your Plants ?

At Multitanks, we know that landscaping your garden is an investment of time and energy. That's why we offer you pozzolan, a mulching solution that is both aesthetic, effective and incredibly durable. Coming directly from volcanic rocks, this rot-proof material is the secret of experienced gardeners who seek to limit watering and reduce the number of weeding that is constantly renewed.

This 20-litre bag of pozzolan, ready to use and with a studied grain size (7/12 mm), is a great ally for the health of your plants. It acts as a natural thermal insulator . Underneath its protective layer, the soil remains cool in summer and less prone to temperature fluctuations, which is especially beneficial for heat-loving plants, such as those used in rock gardens or dry gardens. In addition, its raw composition (100% pozzolan) and its UAB approval (Usable in Organic Farming) make it an environmentally friendly choice, aligned with sustainable gardening practices.

The Undeniable Advantages of Pozzolan for Your Garden ?

There are concrete and measurable benefits to using pozzolan as mulch. Unlike organic mulches that degrade quickly, this volcanic rock ensures peace of mind for years to come. It does not require frequent replacement. Its neutral pH (around 7) and low conductivity ensure that it does not alter the quality of the soil or disturb the balance of your plantings.

Here are the benefits you'll quickly see:

• Drastic Reduction in Weeding : By forming a physical barrier, pozzolan prevents the germination of weeds, saving you precious time.

• Substantial Water Saving : It reduces the evaporation of water from the soil, maintaining essential moisture at the roots. Ideal for dry regions or hot summers.

• High-performance thermal insulation : It protects the roots from temperature extremes, frost in winter and overheating in summer.

• Sustainable and Clean Mulch : Rot-proof and non-degradable, it does not create mud and retains its decorative appearance year after year.

• Usable Anywhere : Compatible with organic farming (UAB), it is safe for your vegetable crops and fruits.

• Alternative to Drainage : It can effectively replace clay pebbles or gravel at the bottom of pots and planters for optimal drainage .

Placement and Specific Applications of this Volcanic Mulch ?

The use of pozzolan is simple and adaptable to various projects. For optimal results and maximum efficiency, the preparation of the ground is essential. Start by weeding the area carefully and making sure the soil is clean.

The instructions for use vary depending on the application:

• Beds, Flowerbeds, Trees and Hedges : A 4 cm thick layer is recommended for effective protection against weeds and moisture retention. A 20 L bag will cover about 1 m² with this thickness.

• Potted Plants and Planters : A thin layer of 1 to 2 cm on the surface is sufficient for a decorative and insulating role. For drainage, cover the bottom of the pot for a few centimetres before adding your potting soil.

• Ground Cover and Dry Gardens : To create a dry garden (with cacti, grasses, drought-resistant plants), the thickness must be more substantial. We recommend a minimum of 8 to 10 cm. The pro tip: spread a geotextile film (unwanted weeds will develop even more difficult) before the pozzolan, leaving the places for your future plants.

The best time for installation is in the spring, once the soil has started to warm up slightly. However, its non-perishable nature and insulating properties allow it to be planted all year round, especially when planting your perennial plants.
