Best soil amendment for enhancing drainage and promoting healthy plant growth.
This horticultural charcoal is a versatile soil amendment designed to enhance plant health and soil quality.

Know before you buy
Horticultural charcoal is pure, untreated carbon without the lighter fluids, additives, or chemicals found in grilling charcoal. It is specifically processed to be safe for plant roots and soil microbiology.
Yes, it is highly recommended for closed-system terrariums. Because it absorbs odors and filters impurities, it helps maintain a fresh environment in containers that lack drainage.
For general soil conditioning, a ratio of about 10% charcoal to 90% potting mix is usually sufficient. You can adjust this based on your plant's specific drainage needs.
Horticultural charcoal is generally pH neutral, though it can help 'sweeten' the soil by absorbing acidic buildup and toxins. It is a safe amendment for almost all plant varieties.
You typically do not need to remove or replace the charcoal once it is mixed into the soil. It remains effective as a long-term soil conditioner throughout the life of the potting medium.
