To do so, blend a small quantity of charcoal with your potting soil, ensuring that it is evenly dispersed throughout the mix.

The specific ratio of charcoal to soil may vary depending on the type of plant being grown, but a general guideline is to use one part charcoal to three parts soil as a rule of thumb.

2. To Absorb Odors

Charcoal is an excellent absorbent for bad and strong odors, which makes it more beneficial for use in indoor plants.

Charcoal can act as a natural water filter by adsorbing contaminants and chemicals, such as chlorine and heavy metals.

Simply place a layer of charcoal on top of the soil or in the bottom of the pot to filter the water as it passes through, providing cleaner water for your plants.

4. To Prevent Mold and Mildew

Charcoal’s natural antifungal properties make it effective in preventing mold and mildew growth in potted plants.

You can crush a few charcoal pieces and sprinkle them on top of the soil or mix them into the potting mix.
