Activated charcoal is our preferred base layer for planting in pots without drainage holes. Sometimes called horticultural charcoal, it is "activated" by processing it at very high temperatures. This increases its absorptive properties, which can help protect plants from over-watering. Charcoal is naturally anti-microbial, with a great capacity to absorb impurities and other toxins, helping protect soil and roots from bacterial and fungal growth.
Perfect for terrariums, cachepots, and other closed planting vessels and suitable for use with all houseplants! Add a ¼" - ½" layer at the bottom of vessels without drainage holes, and then pot following normal procedure using clean potting soil. Take care not to over-water.
12oz bag, sufficient for use in 3-4 four inch pots or 2-3 six inch pots. Ships in a biodegradable bag.
Due to customs restrictions, Activated Charcoal cannot be shipped internationally.
I liked the size of the pieces. It was nice to work with.
Love this activated charcoal - you can put in on the bottom as a drainage layer, or you can mix in throughout the soil to keep it "sweet." The only this I'd wish would be that the bag was a little bigger. When I repot, I always make sure I have some of this on hand.
Seems to be working well for my planter that doesn't have a drainage hole!
