Diatomaceous earth natural diatoms for plants is a natural repellent and a fertilizing and moisture-retaining ingredient. Diatomaceous earth used in agriculture or at home will provide plants with silicon necessary for their proper growth and development...


Plants in the early stages of growth contain silicon (Si) in the form of silicic acid. The concentration of this acid decreases with the age of the plant, approaching zero in mature plants due to the covering of SiO2 particles with organic polyphenols. Drying of the plant also results in the isolation of silicic acid, which leads to a marked reduction. 

Why are diatoms (diatomaceous earth) for plants so important?

  • Structural role: Si contributes to increased compressive strength and stiffness of plant cell walls that participate in photosynthesis by improving the ability to capture light. It also makes the plant more resistant to drought. The presence of Si reduces evaporation, contributing to the maintenance of water in the tissues.
  • Physiological role: increased stiffness of oxygen channels in tissues facilitates the penetration of oxygen through the roots.
  • Protective role: Si increases resistance to pathogens, insects and molluscs. It also protects plants against the toxicity of excess metals such as manganese and iron by increasing their distribution throughout the plant and contributing to their easier dissolution. Silicic acid is also formed into silicates surrounding the microparticles of oxides of these metals, increasing their stability.
  • Role of pest repellents: natural repellent: unique structural properties make diatoms for plants a remarkable natural remedy against unwanted plant pests. Cylindrical diatom shells mechanically damage the pest coatings, repel them and limit reproduction.
  • The fertilizing and irrigation component: diatoms for plants, due to their high porosity and sorption properties, they keep the moisture level in the soil longer, so essential for the proper functioning of plants, including vegetables. Cover the plant with diatomaceous earth for plants. Your fruit trees, vegetables and other plants will grow better and be tastier. 



In the case of small house pots, sprinkle the soil under the plant with a thin layer of diatoms. In the case of garden cultivation, use larger quantities at your own discretion. Plot the plants in the morning or evening.

Diatoms (diatomaceous earth) as a natural repellent – natural protection of plants against garden or wood pests.

Sprinkle with diatoms on both sides of the leaves. Avoid using diatoms on flowers, as they can damage beneficial insects such as bees. The diatoms do not kill earthworms if we carry them to the surface of the earth without deeper soil penetration. Sprinkle or spray the tree trunk with a solution of diatoms (1/3 glass per 1 liter of water) to prevent the pests from re-infesting the tree.

Recommendations and precautions

Do not allow the product to get into your eyes, as it may cause them to dry out. Avoid long-term inhalation of high concentrations of the product, as this may lead to irritation of the respiratory system. Wear a face mask and / or proceed with caution especially when you have problems with your lungs and respiratory system, eg asthma. Never use crystalline diatoms or those that do not have food quality. They can be dangerous to the health of living organisms.
