Activated Charcoal

$ 12.50

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.

I love it!

I started to use activated charcoal recently and it is definitely has outperformed lava or pumice rocks. Pistils nursery offers the purest form of activated charcoal and it's antimicrobial qualities help to prevent root rot. While pumice and lava rocks don't look good anymore as time goes by, especially in terrariums, activated charcoal still shines! Would definitely buy again.

Horticultural benefits aside, I would like to add that the cut of these pieces and the cleanliness of this product are quite pleasing. The biodegradable brown sack this comes in is a plus. And, to echo others, a larger quantity, especially at this price point, would be much appreciated.

A game changer!

I absolutely LOVE this activated charcoal- I have a couple of planters with no drainage holes, and this stuff is magical for making sure my plants stay happy and not overwatered. I love that the packaging is so eco- friendly, and as with EVERYTHING I have purchased from Pistils so far, it is excellent quality! I have bought two bags so far!
