Expanded clay as drainage for flower pots

A layer of expanded clay placed at the bottom of a pot helps drain excess water and improves air circulation in the root zone. This solution is particularly useful for plants sensitive to excessive moisture, as well as in large planters, boxes, and garden containers.

Expanded clay as a soil additive

Expanded clay can be mixed with soil or other growing media to increase its permeability and prevent excessive compaction. The looser structure facilitates air access to the roots and more efficient drainage of excess water.

The amount of expanded clay should be adjusted according to the type of plants and the required drainage of the mixture.

Expanded clay for mulching

When spread over the surface of the growing medium, expanded clay creates a durable and decorative mulch layer. It helps reduce moisture evaporation and weed growth, while also providing an attractive finish to the surfaces of pots, planters, and flower beds.

Unlike organic mulches, expanded clay does not decompose quickly and can retain its properties for many seasons.

How to use Biovita expanded clay?

As drainage: pour a suitable layer of expanded clay onto the bottom of a pot or container, then fill it with the appropriate growing medium.

As a soil additive: mix expanded clay with soil, adjusting the amount according to the plants’ needs and the desired drainage of the mixture.

For mulching: spread an even layer of expanded clay on the surface of the growing medium around the plants.

Before using expanded clay in hydroponic cultivation, it is recommended to rinse it thoroughly with clean water.
