FAQs
What plants is the Cactus & Succulent Potting Mix best for?
Cacti, succulents, and other arid-loving plants like aloe, jade (Crassula), Haworthia, Euphorbia, and most desert cacti. It’s designed to keep roots airy and dry out fast between waterings.
What’s actually in the Cactus & Succulent Potting Mix?
A mineral-forward blend built around pumice (aeration), perlite (drainage), and zeolite (nutrient holding and pH buffering). No hidden fillers or mystery compost.
What size are the particles?
Screened to roughly 2–6 mm so roots don’t suffocate and water can move through quickly without pooling.
Is the Cactus & Succulent Potting Mix peat-free?
It’s a mineral mix focused on pumice, perlite and zeolite rather than peat-heavy ingredients.
Will the Cactus & Succulent Potting Mix help prevent root rot?
Yes—fast drainage + lots of air around roots = fewer soggy-soil problems. The big win is avoiding the constant moisture that cacti and succulents hate.
Indoor or outdoor?
Both. Indoors it keeps overwatering dramas in check; outdoors it sheds heavy rain quickly (still make sure your pots have drainage holes).
Do I need to add sand or extra perlite?
No. It’s ready to use straight out of the bag. If you’re an ultra-gritty grower or a heavy waterer, you can cut in extra pumice/perlite or a coarse grit to make it even faster draining.
Can I use the Cactus & Succulent Potting Mix for lithops and other ultra-dry species?
Yes, but most lithops people bump up the grit even more. Mix in additional pumice or a coarse grit to suit your watering style.
What about tropical succulents like Hoya?
Hoya prefer a chunkier aroid-style mix with bark. This product will drain well, but they often want more organic chunks than cactus types do.
Is the Cactus & Succulent Potting Mix suitable for aloe?
Yep. Aloe appreciate the same free-draining, airy conditions this mix provides.
Is the Cactus & Succulent Potting Mix okay for jade (money plant)?
Perfect. Jade are notorious for rotting in regular potting soil—this mix fixes that by drying down faster.
Can I use the Cactus & Succulent Potting Mix for bonsai succulents?
You can. For bonsai styling, some growers add more grit or akadama alternatives (pumice/diatomite/zeolite) for even tighter control over moisture.
How often should I water in the Cactus & Succulent Potting Mix?
Water thoroughly, then wait until the mix is fully dry before watering again. That might be every 10–14 days indoors in summer and much less in winter. Always go by the dryness of the mix, not the calendar.
Should I bottom-water or top-water?
Either works. Top-watering helps flush salts; bottom-watering can keep the top layer drier (handy for fungus-gnat prevention). Just let the pot drain fully.
What pot type is best—terracotta or plastic?
Terracotta breathes and speeds drying; plastic holds moisture a little longer. Pick based on your environment and how often you want to water. Drainage holes are non-negotiable.
Do I need a layer of rocks at the bottom?
No. “Drainage layers” actually raise the perched water table. Fill the whole pot with this mix and rely on the pot’s drainage holes.
Do I need to rinse or pre-wet the mix?
Not required. If you want to reduce initial dust, you can lightly moisten it in a tub before potting.
How tightly should I pack it?
Firm enough to support the plant, but don’t ram it in. You want air pockets—gentle tamping is fine.
When should I repot?
Every 12–24 months, or when you see circling roots, slow growth, or the mix is breaking down. Spring is ideal for most succulents and cacti.
Can I reuse the Cactus & Succulent Potting Mix?
Yes—if it’s clean and not compacted. Shake off old fines, add some fresh mix and a bit of new pumice/perlite to restore structure.
Does the Cactus & Succulent Potting Mix come fertilised?
It’s a nutrient-smart, mineral-forward medium. Feed your plants lightly during active growth with a succulent/cactus fertiliser (liquid or slow-release both play nicely with this mix).
What pH does the Cactus & Succulent Potting Mix run at?
Neutral-leaning and stable thanks to the mineral ingredients. If you’re chasing exact numbers, test with a soil pH kit—results vary with your water and fertiliser.
Will the Cactus & Succulent Potting Mix attract fungus gnats?
Mineral mixes are far less attractive to gnats than peat-heavy soils. Keep the top layer dry and avoid overwatering. A thin top-dress of grit or diatomite makes the surface even less gnat-friendly.
Is the Cactus & Succulent Potting Mix sterile?
It’s made from clean, high-grade minerals rather than composted organics. If you need lab-sterile (e.g., for seed starting), pasteurise at home or use a dedicated seed-raising medium.
Is the Cactus & Succulent Potting Mix safe for pets?
The ingredients are inert minerals, but it’s not food. Keep pets from chewing or ingesting the mix. As with any dusty product, store sealed and use common-sense handling.
Any dust I should worry about?
Mineral mixes can have a little dust. Open the bag gently and avoid breathing it in—use outdoors or in a ventilated area.
How much do I need for my pot?
Use the soil volume calculator on the product page—enter your pot shape and dimensions and it’ll tell you how many litres to buy.
What if my plant still looks sad after repotting?
Check light first (most succulents want bright, indirect to several hours of direct light), then watering cadence. If growth is pale/leggy, increase light; if leaves are mushy or translucent, you’re watering too soon.
Can I mix the Cactus & Succulent Potting Mix with bark or compost?
You can, but you’ll slow the drainage. If you need more organic matter for a specific plant, add a small percentage at a time and watch the dry-down rate.
Is the Cactus & Succulent Potting Mix good for terrariums?
Closed terrariums stay too humid for most cacti/succulents. For open, dry dish gardens it’s fine—just keep them in bright light and go easy on water.
Will the Cactus & Succulent Potting Mix stain patios or decks?
The minerals themselves don’t stain, but leachate can leave marks on porous surfaces. Use saucers or lift pots slightly for airflow and cleanliness.
Does the Cactus & Succulent Potting Mix break down fast?
Mineral ingredients hold structure much longer than peat-heavy soils. You’ll still repot eventually, but the mix won’t collapse quickly.
What fertiliser schedule do you recommend?
Light, infrequent feeds during active growth (spring–summer). Half-strength liquid every 4–6 weeks or a low-rate slow-release pellet at pot-up is plenty for most succulents and cacti.
Can I use the Cactus & Succulent Potting Mix straight for seed raising and cuttings?
For chunky cuttings—yes. For tiny seeds, most growers prefer a finer seed-raising medium or sift this mix to the smaller fraction for better seed-to-soil contact.
Is the Cactus & Succulent Potting Mix okay for balcony gardens with heavy rain?
Yes—just ensure pots have drainage and consider terracotta or a slightly grittier blend if your site gets constant downpours.
Anything else I should pair the Cactus & Succulent Potting Mix with?
Optional but handy: a top-dress of coarse grit/diatomite to keep the surface drier, yellow sticky traps as a gnat early-warning, and a gentle succulent fertiliser for the growing season.
