Horticultural Charcoal

by Dirt Bar


Horticultural charcoal (also called “activated charcoal”) is antimicrobial and absorbent, making it a perfect choice for layering at the bottom of pots that lack drainage to help your plants stay healthy and avoid root rot. Perfect for cachepots (decorative pots with no drainage), terrariums, or any other planting project where drainage is an issue. Always take care not to overwater and repot your plants as you normally would once your layer of charcoal has been added. You can also mix charcoal into your soil for other planting projects for the added antimicrobial benefits and to increase aeration.
