Elevate Your Gardening with Diatomaceous Earth 1kg

Experience the numerous benefits of Diatomaceous Earth (DE) in your garden, a natural, non-toxic, and incredibly absorbent silica rock formed from fossilised diatoms. DE is versatile enough to be used as a growing medium in hydroponic gardening, as an insecticide, and as a source of silica for soil mixes. With its high level of porosity, it helps retain water for plants while providing excellent drainage and breathability to the soil.

Features and Benefits

  • Natural and non-toxic: DE is a safe choice for gardeners looking for organic solutions to improve soil and eliminate pests.
  • Highly absorbent: With excellent water retention, DE keeps plants well-hydrated and reduces the need for frequent watering.
  • Improved soil porosity: DE's unique properties promote aeration and breathability in the soil for healthier root growth.
  • Insecticide properties: DE's microscopic sharp edges effectively control pests by damaging their waxy exoskeletons, leading to dehydration.
  • Soil enrichment: DE provides a valuable source of plant-available silica, promoting stronger and healthier plant growth.

How to Use

  1. For potting soil mix, combine 1 cup of DE per 25L of soil. Increase the percentage up to 15% if you aim to enhance the water holding capacity further and reduce watering needs.
  2. When reusing soil after harvest, mix in an additional 1/8th cup of DE.
  3. For organic pest control, sprinkle DE on the soil surface, around the base of plants, under potted plants, or in areas with high pest presence.
  4. Use a flour sifter, garden duster, or fine mesh strainer for even application of DE.

Aqua Gardening Suggests These are Best For

Diatomaceous Earth is ideal for both experienced and novice gardeners who embrace organic gardening practices. It is perfect for those looking to improve their soil's water retention, breathability, and overall health while also controlling pests through a natural, non-toxic method. DE is an excellent choice for hydroponic gardening enthusiasts and landscape gardeners who aim to establish strong and healthy plant growth from the very beginning.


Is Diatomaceous Earth safe for my plants?

Yes, Diatomaceous Earth is safe for plants and is often used to improve the soil quality, enhance water retention, and provide an organic method of pest control. Mixing DE into your potting soil or garden beds enhances the health and growth of your plants without causing any harm.

Can Diatomaceous Earth be used as a pesticide?

Absolutely! Diatomaceous Earth is an effective natural insecticide. Its microscopic particles work by damaging the exoskeleton of insects, causing them to dehydrate and eventually die. Simply sprinkle the DE on the surface of the soil, around the base of plants, and other areas where pests are present to protect your plants without using harsh chemicals.

Will Diatomaceous Earth harm beneficial insects like bees and ladybugs?

Diatomaceous Earth is not selective when it comes to killing insects, so it is possible for it to harm beneficial insects as well. To minimise harm to beneficial insects like bees and ladybugs, try not to apply DE directly onto flowers or plants that they are known to visit often. You can also choose to apply DE during times when beneficial insects are less active, such as early morning or late evening.

How often should I apply Diatomaceous Earth in my garden?

The frequency of applying Diatomaceous Earth in your garden depends on various factors such as the severity of the pest infestation and weather conditions. If you are experiencing persistent pests or heavy infestations, you may need to apply DE more frequently. In general, reapply DE every 1-2 weeks or after heavy rain or watering, as it can become less effective when wet. Remember that DE might affect beneficial insects, so careful application is important.

Can I use Diatomaceous Earth indoors for houseplants?

Yes, Diatomaceous Earth is suitable for indoor use with houseplants. Adding DE to your potting mix can help retain moisture and improve overall soil quality. To use DE for indoor pest control, simply sprinkle it on the surface of the soil and around the base of your houseplants.

Is Diatomaceous Earth safe for pets?

Diatomaceous Earth is generally considered safe for pets. However, it is essential to use food-grade DE for any application where your pets might come into contact with it. Avoid using DE that is labeled for industrial applications, as it may contain harmful chemicals. As always, it is best to consult your veterinarian if you have concerns about your pet's safety regarding DE exposure.
