How should I use activated charcoal in my terrarium or mossarium?
For terrariums or mossariums, you can either mix a small amount of activated charcoal with the soil to improve moisture and odour control, or place a thin layer at the bottom before adding soil to help with drainage and prevent mould growth.
Is activated charcoal suitable for all types of houseplants?
Yes, it’s suitable for most houseplants, especially beneficial for those requiring good drainage and odour control. Mixing activated charcoal into the soil can help absorb excess moisture and nutrients, releasing them slowly to prevent root rot and nutrient burn.
Can activated charcoal help with the smell of my indoor plants?
Absolutely, activated charcoal is excellent at absorbing odours. Adding it to your plant’s soil or directly in decorative pots helps neutralise smells, making it ideal for indoor environments where air quality is a concern.
