When it comes to growing vibrant plants, it’s all about the quality of the soil. Pumice rock is an ideal growing medium. Pumice rock has a variety of characteristics making it useful throughout your garden. Providing excellent aeration to the soil, it loosens heavy clay soil and retains moisture well.

Pumice rock is a type of igneous rock which is formed from molten or partially molten material. These types of igneous rocks are classified as volcanic. Because of the rapid cooling process, mineral deposits in the rock are trace or nonexistent. These rocks are classified by
texture and color. Pumice contains many small vesicles, which is the primary reason it is so light in weight. Pumice rock is mined throughout the world in regions with volcanic activity and Pumice deposits.

The roots of plants are living organisms requiring a continual supply of oxygen, the introduction of air into the soil even though it is wet is very important. Likewise, roots are constantly releasing carbon dioxide, which must be removed from the root zone. Plants require that these gases be supplied or exhausted via soil pores. Thus, a good soil must be porous to permit the exchange of gases while also adequately retaining water to meet the needs of the plant. Additionally, the plant must obtain more than a dozen elements from the soil for its growth.
