Extended Product Information

FAQs

Is this product safe for my indoor plants?

Yes, it is 100% natural, non-toxic, and specifically designed for use in potting soil and houseplant containers.

Can I use this with chemical fertilizers?

Yes, it is a physical soil amendment and does not react with standard fertilizers.

How often do I need to reapply the top dressing?

Reapply whenever the 0.5cm layer is disturbed or becomes mixed into the soil during watering.

Does it contain added nutrients?

No, it is a physical soil improver that helps with structure, drainage, and moisture retention rather than providing chemical nutrients.

Will this work in my compost bin?

Yes, adding it to your compost can help maintain the moisture balance and keep the material aerated.

Is this harmful to earthworms?

No, it is safe for beneficial soil organisms like earthworms.

Troubleshooting

The top dressing layer is sinking into the soil after watering

Water your plants gently from the side or using a watering can with a fine rose to avoid displacing the layer.

Fungus gnats are still present after application

Ensure the top dressing is at least 0.5cm thick and that you are not overwatering, as fungus gnats are attracted to consistently saturated conditions.

Pros and Cons

Pros

  • Prevents soil compaction in container plants
  • Improves moisture retention and drainage simultaneously
  • Effective at discouraging fungus gnats as a top dressing
  • Safe, non-toxic organic material
  • Highly versatile for both houseplants and garden soil

Cons

  • Requires manual mixing for optimal 10-20% ratio
  • Top dressing layer needs to be maintained at 0.5cm to remain effective
  • Product is lightweight and can be messy if handled in windy conditions

Setup, Compatibility & Care

To integrate this improver into your gardening routine, follow these guidelines:

  1. Mixing: For potting soil or compost, calculate 10-20% of your total container volume and fold the diatomaceous earth evenly into the mixture to ensure roots have contact with the particles.
  2. Top Dressing: To deter pests, clear the debris from your soil surface and apply a consistent, level layer approximately 0.5cm thick. Reapply if the layer is disturbed by watering or physical movement.
  3. Compatibility: This product is fully compatible with most organic and inorganic potting mixes. It is especially recommended when transitioning plants to peat-free alternatives.
  4. Storage: Keep the bag in a dry location. If the product gets wet in the bag, it will still be effective but may be harder to measure accurately when dry.
