Benefits of HortiChar

• Detoxifies Soil: Absorbs impurities, toxins, and harmful microbes to keep the mix "sweet" and healthy.
• Improves Soil Structure: Adds lightness and airflow to prevent compaction and support healthy root function.
• Enhances Nutrient Retention: Holds onto essential nutrients and releases them slowly as plants need them.
• Supports Root Health: Reduces risks of rot and disease by improving aeration and creating a healthier root zone.
• Boosts Microbial Activity: Provides porous surfaces where beneficial microorganisms can thrive.
• Great for Indoor Mixes: Ideal for aroids, hoyas, terrariums, propagation, and moisture-sensitive plants.
• Long-Lasting & Eco-Friendly: Breaks down slowly, remaining effective in soil for years.

Safety Tips

Wear gloves and a mask when handling charcoal, as it can be dusty. Lightly moisten before use and wash hands after potting.
