FAQs:
What exactly is Horticultural Potting Charcoal?
A chunky, carbon-rich soil conditioner that boosts aeration and drainage, helps “sweeten” mixes by binding odors/impurities, and supports beneficial microbes in containers, terrariums and living soil setups.
What sizes do you stock and what do they suit?
We’ve got 2–5 mm, 10–15 mm, and 15–20 mm. Go 2–5 mm for aroid mixes/terrariums, 10–15 mm for orchids and general chunky potting, and 15–20 mm when you want maximum airflow in big pots or as a drainage/filter layer.
How much should I add to my potting mix?
Mix in 5–20% by volume. As a guide, a 5 L bag will amend ~100 L of mix at 5%, ~50 L at 10%, or ~25 L at 20%.
Is Horticultural Potting Charcoal okay for aroids (Monstera, Philodendron, Anthurium, etc.)?
Yep—this product is literally tuned for aroids and other tropicals that hate soggy roots. It helps keep mixes airy while holding just enough moisture in its pores.
Will Horticultural Potting Charcoal help with fungus gnats and sour smells?
It won’t “kill” gnats, but it helps keep the mix fresher and less inviting by improving drainage and binding funky odors. Pair it with good watering habits and sticky traps if gnats are already present.
Do I need to rinse Horticultural Potting Charcoal before use?
A quick rinse to remove loose dust is smart—especially for houseplants and terrariums. Tip it into a colander or bucket, give it a brief swish, and you’re good.
Should I “charge” the charcoal first?
Optional but beneficial: soak it for a few hours in compost tea, diluted liquid feed, or runoff from a healthy brew. Pre-loading pores with nutrients means less initial nutrient “soak up” from your soil.
Is the Horticultural Potting Charcoal same as activated charcoal or biochar?
No. Ours is horticultural charcoal (chunky, natural hardwood). Activated charcoal is processed for ultra-high adsorption (great for filtration/medicine), and biochar is made to live in soils long-term for carbon sequestration and CEC. For potting mixes and terrariums, chunky horticultural charcoal is the easy, no-fuss option.
What’s Horticultural Potting Charcoal made from? Any chemicals added?
Pure hardwood charcoal with no chemical additives.
Will Horticultural Potting Charcoal change pH or mess with nutrients?
It’s generally neutral-leaning and helps buffer mixes. It can hold (not steal) nutrients in its pores and make them more available to roots over time, especially if you pre-charge it.
Can I use Horticultural Potting Charcoal in terrariums and bottle gardens?
Absolutely. Add a thin layer under your substrate for odor control and to keep things fresher between maintenance.
Is Horticultural Potting Charcoal safe around pets and kids?
It’s just charcoal, but the dust is dusty—store out of reach and avoid inhalation. Keep pets from chewing the chunks (common sense stuff).
How does Horticultural Potting Charcoal help prevent root rot?
By opening up the mix so excess water drains and oxygen can reach roots. Healthy airflow + microbe support = a less rot-friendly environment.
Can I top-dress with Horticultural Potting Charcoal, or does it have to be mixed in?
Both work. Mixing 5–10% through the potting blend is ideal. A thin top-dress can help with smells and surface souring, but mixing gives the full drainage/aeration benefit.
What plants benefit most?
Aroids, orchids, hoyas, epiphytes, cacti/succulents (in moderation), and any indoor plant that prefers a freer-draining substrate.
Is Horticultural Potting Charcoal okay in hydro or recirculating systems?
Not recommended for recirculating hydro—fines can cloud water and charcoal fragments aren’t ideal in pumps/lines. It’s a substrate amendment, not a hydro media.
How long does Horticultural Potting Charcoal last in pots?
Years. Charcoal is stable; it doesn’t “break down” like bark. You can reuse it when repotting—just rinse and re-mix.
How much does a 5 L bag cover?
Rule of thumb: at 10% in your mix, 5 L will blend into ~50 L of substrate (enough for several medium pots).
Can I use Horticultural Potting Charcoal with coco, bark, LECA, pumice, etc.?
Yep. It plays nicely with aroid staples like coco chips, orchid bark and pumice/perlite. Start with 5–10% charcoal alongside your chunky ingredients.
Does Horticultural Potting Charcoal replace perlite or bark?
No—think of it as another “chunk” in the toolkit. Perlite/pumice = lightweight aeration; bark = structure and biology; charcoal = aeration + adsorption + microbe support. Use together for best results.
Will Horticultural Potting Charcoal make my soil too dry?
No. It actually holds a bit of moisture in its pores while still draining well. If your plant likes it wetter, just use the lower end (5–10%) and keep some finer ingredients in the mix.
Any prep tips for repot day?
Pre-moisten your base mix, rinse the charcoal, optionally pre-charge, then blend evenly. Don’t crush it—those pores and chunks are the point.
Can I use Horticultural Potting Charcoal as a bottom “drainage layer” in pots?
You can, but real drainage comes from the whole mix being well-structured. If you do a base layer, keep it shallow and still build a chunky mix above.
Will Horticultural Potting Charcoal stain or leave black residue?
The dust will—during prep. Rinse outside or over a laundry sink and you’ll avoid black drips indoors.
How should I store Horticultural Potting Charcoal?
Dry, sealed, and out of direct weather. It has an essentially indefinite shelf life.
Is Horticultural Potting Charcoal compostable or garden-bed friendly?
You can mix leftovers into garden beds or compost to add structure and microbe habitat. It’s inert and soil-friendly.
Pickup or shipping options?
We offer both. Local pickup is available from our Bellambi (NSW) location; shipping is calculated at checkout.
What’s the simplest aroid mix recipe using Horticultural Potting Charcoal?
Easy mode: 1 part potting soil or coco base, 1 part bark, ½ part perlite/pumice, ¼–½ part horticultural charcoal. Adjust chunkiness to plant + pot size.
Does Horticultural Potting Charcoal play nice with living soil setups?
Yes. It’s ideal in living soils—gives microbes a porous home, helps buffer moisture, and pairs well with organic inputs.
