Product description
What is Biochar? Biochar is a type of charcoal made from plant materials such as hardwoods, grasses, and agricultural and forest residues that are decomposed at high temperatures, often during renewable energy production. During the process, the physical and chemical properties of the plant material change into a porous, stable, carbon-rich by-product known as biochar. Why use it? Biochar has been used in agriculture for many centuries. Adding biochar to soil has the potential of increasing soil carbon, soil nutrient content, increased water retention and water-soluble nutrients, and increased beneficial microbial life. DIRECTIONS Best results are achieved when adding this mix to your soil at least 5-7 days BEFORE planting. However, this can be used at any time in the planting process. Optimal ratio for most gardeners is 5-10% biochar in the top 6 inches of their soil. (1 part Bio Char to 9 parts planting soil). Indoor Plants(container plants, seeds, cuttings, transplants): Use a small rake or spoon and hand-mix this product around the plant within your desired container. Best results are adding close to the root zone. You can also just layer a light dusting on the top and water in as usual. Outdoor Plants (Gardens, Bedding Plants, Ornamentals): Use your conventional tiller and rake and till directly into the soil. Adding more over time can increase product performance. Trees and Shrubs: Best when applied to the root zone area. Rake into this area and water as desired. Compost Mix: Mix as needed within your compost process - use as desired as you would your final compost. This product is not intended to be used as a soil substitute.

5.0 out of 5 stars A Must-Have for Healthy Plants—Superior Quality & Versatile Use
Verified PurchaseIf you’re serious about healthy plants, better drainage, and preventing root rot, Harris Horticultural Charcoal is an absolute game-changer. I’ve tried several brands, but this one stands out for its high-quality, fine yet effective texture and multiple uses in both gardening and home applications.
🌿 Improves Soil & Prevents Root Rot
As a plant lover, I use this horticultural charcoal in my indoor and outdoor pots to help with moisture control. It absorbs excess water while still allowing soil to retain the right amount of hydration—a lifesaver for plants prone to overwatering! Since using it in my orchid and succulent mix, I’ve noticed healthier roots and less risk of fungal growth.
💨 Odor Absorption & Air Purification
Beyond gardening, I’ve also used this charcoal as a natural deodorizer in my home. It works amazingly well at absorbing moisture and odors in areas like the bathroom, fridge, and even my compost bin. If you’re looking for a chemical-free way to neutralize smells, this is a fantastic solution.
✅ Premium Quality & Great Value
The fine, uniform pieces make it easy to mix into potting soil, and it’s not overly dusty like some lower-quality alternatives. A little goes a long way, so this bag offers excellent value for the price.
🌎 Eco-Friendly & All-Natural
I appreciate that this is 100% natural charcoal, free of additives or fillers. It’s a sustainable choice for both gardening and household use, and it doesn’t have that artificial or chemical-laden smell that some other charcoals do.
Final Verdict:
Whether you’re a plant parent, terrarium enthusiast, or just looking for a natural deodorizer, Harris Horticultural Charcoal is a must-have. The quality is top-tier, the benefits are undeniable, and the versatility makes it a staple in my home. I highly recommend it—this is one of those products you don’t realize you need until you try it!
💡 Pro Tip: Rinse before use to remove excess dust, and mix it with potting soil for optimal results.

5.0 out of 5 stars Good for my plants
Verified PurchaseThis horticultural charcoal is a good product. The pieces are small & not too dusty. It’s beneficial for houseplants, as it aerates the soil, & protects the roots & soil from bacteria & fungus. I mix up my own potting soil blend, & this brand of charcoal is the one I always have good luck with. I highly recommend it.

5.0 out of 5 stars Great for Vivarium builds and Springtail cultures
Verified PurchaseI used this for my all my Vivarium and Bioactive reptile enclosures. This is by far the best I could find anywhere for Horticultural grade charcoal. Bought multiple times and will again.
