FAQs
What exactly is in this Indoor Plant Potting Mix?
A premium blend of coco coir, perlite, and pine bark — no filler junk, just the good stuff for airflow, drainage and moisture balance.
Which plants is the Indoor Plant Potting Mix best for?
It’s made for a wide range of houseplants: ferns, aroids (Philodendron, Monstera, Anthurium, Alocasia), figs (Ficus), Calathea and more. If it lives indoors and likes moisture with good airflow, it’ll feel at home here.
Is the Indoor Plant Potting Mix pre-fertilised or “charged”?
No explicit nutrient charge is listed. Treat it as a high-quality base mix and feed with your choice of liquid or slow-release fertiliser as you go.
Can I use any fertiliser with the Indoor Plant Potting Mix?
Yep — it’s compatible with all nutrient types (liquid or slow-release). Pick a program that suits your plant and season.
How does each ingredient help my plants?
Coco coir holds moisture without getting swampy; perlite increases oxygen around roots and speeds drainage; pine bark adds chunky structure so roots can breathe. That trio is a proven combo for indoor plants and aroids.
Will the Indoor Plant Potting Mix help prevent root rot?
It helps — the perlite + bark keep the mix airy so water moves through instead of suffocating roots. You still need to water properly and use pots with drainage.
Is the Indoor Plant Potting Mix good for aroids specifically?
Yes. Aroids like chunky, well-aerated mixes. Coco + bark + perlite is a staple recipe in aroid circles because it balances moisture and air.
What pot sizes will 5L fill?
As a rough guide, 5L fills about one 20 cm nursery pot (depending on height) or two 14–15 cm pots. Plan a little extra for top-ups after settling.
Do I need to add anything else to the Indoor Plant Potting Mix?
Not required. Optional tweaks (advanced users): a pinch of slow-release fertiliser, a bit more bark for thirstier environments, or extra perlite if your space stays humid and the mix dries slowly.
How often should I water in this mix?
Water when the top 2–4 cm feels dry. Coco holds moisture well; overwatering is the usual mistake. Frequency depends on light, pot size, season and airflow.
Will this attract fungus gnats?
Any consistently damp potting medium can host fungus gnats. Prevention is about watering: let the top layer dry between waterings, use pots with drainage, and avoid saucer swamps. Sticky traps and letting the surface dry out are simple controls.
What if I already have gnats?
Let the surface dry, bottom-water when possible, add yellow sticky traps, and consider biological controls like Bti if needed. Repot with fresh medium if it’s bad.
Is the Indoor Plant Potting Mix safe for Calathea and other “drama queens”?
Yes — they like consistent moisture without sogginess. This blend holds moisture but still breathes, which is exactly what they want.
Can I use the Indoor Plant Potting Mix for ficus (Fiddle Leaf Fig, Rubber Plant)?
Yes. Ficus appreciate free-draining mixes that don’t stay wet for days; this hits that balance.
Is the Indoor Plant Potting Mix suitable for propagation and cuttings?
For cuttings, many growers use lighter mixes with extra perlite for faster drainage. You can use this as-is or cut it 1:1 with additional perlite for very soft stems.
Should I mix in LECA, charcoal or worm castings?
Optional. Advanced aroid folks sometimes add these for structure or micro-nutrients, but they’re not essential for success with this base mix.
What pH is it?
The product page doesn’t specify a pH. Coco-based mixes typically trend slightly acidic to near-neutral after fertilising, which suits most indoor plants. Feed and flush as per your nutrient schedule.
How long before I need to repot again?
Usually every 12–18 months for actively growing houseplants, or when roots circle the pot, water rushes straight through, or growth stalls.
Will the bark break down?
Over time, yes — all organic components do. That’s normal and a sign to refresh or up-pot.
Can I reuse the Indoor Plant Potting Mix after a plant dies or is repotted?
You can, but sift out old roots and refresh with new mix. If you had pests/disease, discard or solarise instead of reusing.
Does the Indoor Plant Potting Mix work in self-watering pots?
Yes, but watch moisture — coco wicks well. Keep the reservoir smaller at first and let the top few centimetres dry to discourage gnats.
Any special tips right after repotting?
Soak the root ball, water through once to settle the mix, then let the top dry before the next drink. Don’t fertilise heavily for 1-2 weeks while roots recover.
Is it OK for low-light plants?
Yes — but water less frequently in low light because the mix will dry slower.
Indoor vs outdoor use?
Designed for indoor containers. Outdoors it may dry too fast or attract gnats if kept too wet; choose an outdoor blend for garden beds and large patio pots such as our Chunky Potting Soil.
Can I top-dress with compost?
You can, but compost can raise gnat pressure indoors. If you do, keep it minimal and let the surface dry fully between waterings.
Is the Indoor Plant Potting Mix pet-safe?
No specific pet-tox data is provided. The components are common potting mediums, but curious pets can still dig or ingest mix. Keep plants out of reach and consult your vet for plant/animal-specific advice.
What’s the bag size and weight?
It’s a 5-litre bag (volume). Weight varies with moisture content — think in litres for planning.
How many bags do I need?
Rule of thumb: 5 L ~ one 20 cm pot, or two smaller 14–15 cm pots. For multiple plants, add volumes together and round up so you’re not short mid-repot.
Click & Collect available?
Yes — Bellambi pickup is shown on the product page (usually ready in ~24 hours). Availability can change; check the page before you drive.
Shipping options?
Standard site shipping applies; see the Shipping Policy linked in the footer for details and thresholds.
Anything I should NOT do with this mix?
Don’t block drainage holes. Don’t keep it constantly wet. Don’t tuck plants into oversized pots “to grow into” (the mix will stay wet too long).
Quick care recipe for success in this mix?
Bright, indirect light + pot with drainage + water when the top 2–4 cm is dry + steady, light feeding = happy roots and steady growth.
Where can I learn more about indoor potting mixes?
We’ve got a detailed blog on choosing and using indoor potting mixes for Aussie growers — worth a skim if you want to nerd out on ingredients.
Why this mix over a generic “all-purpose” soil?
Generic soils often stay dense and wet indoors. This blend is built specifically for houseplants — airy structure + moisture retention without the bog — which means fewer root issues and more consistent growth in typical indoor conditions.
Any gnat-prevention housekeeping tips?
Let the top layer dry, empty saucers, increase airflow, and use sticky traps during spring/summer. If you bring in new plants, isolate and repot into fresh mix to avoid hitchhikers.
What if I grow in very dry, hot rooms?
Blend in a little extra coco coir or use a slightly larger pot to stretch moisture between waterings — just keep drainage strong.
What if my space is cool and humid?
Up the perlite/bark fraction or water less often so the root zone stays oxygenated.
Is the Indoor Plant Potting Mix ok for beginners?
Absolutely. It’s forgiving, easy to wet, and hard to over-compact — a clean start for new plant parents.
