Soil & Substrates

Soil & substrates-matching mix to plant type

• Range: ready-made blends for aroids, Goeppertia and Maranta, Hoya, Ficus, cacti, palms, carnivorous plants, terrariums and more.
• Base vs specialist: base and universal mixes work as starting points; more demanding plants benefit from tailored recipes.
• Components: pine bark, coco coir, perlite, pumice, expanded clay, sphagnum, sand, vermiculite and worm castings let you tune drainage and water-holding.
• Fast-draining options: cactus, succulent and bonsai substrates dry quickly and keep more air around roots.
• Moisture lovers: Calathea, Maranta, terrarium and carnivorous blends hold moisture evenly without turning into sludge.
• Semi-hydro: mineral and inert options suit setups where nutrients come from solution rather than from the soil itself.

Soil & Substrates, where root comfort actually starts

Soil and substrates decide how a pot dries. If mixes stay heavy for days or turn to dust within 24 hours, watering will always feel like guesswork, no matter how careful you are with the watering can at home.

Here you can compare ready-made potting mixes for common plant groups, plus components like bark, pumice, mineral grit, coir and semi-hydro substrates so you can tune how fast water moves through the root zone.

Substrates by root style

• Aroid & tropical foliage mixes: airy, moisture-holding blends for climbing and forest-floor foliage that like damp but oxygenated roots.
• Calathea, Maranta & terrarium blends: finer textures that stay evenly moist yet breathable for moisture-loving and cabinet plants.
• Cactus, succulent & bonsai substrates: mineral-heavy mixes that drain fast and dry quickly for arid plants that dislike lingering moisture.
• Carnivorous plant mixes: low-nutrient, airy substrates paired with rainwater or distilled water only.
• Base mixes & components: neutral starting blends plus bark, grit, coir and inert substrates so you can adjust water-holding versus drainage yourself.

Ingredient behaviour and mix design are unpacked in The Ultimate Guide to Houseplant Substrates; here the aim is simple: pick the mixes or components that match how your plants behave at the roots.

When mix, not watering, is the problem

• pots stay heavy and cool long after watering,
• water pools on top instead of soaking in evenly,
• substrate has compacted into mud or fine dust,
• roots form a tight outer ring with little growth inside.

In those cases, changing the schedule will not fix things. Roots either need more air, or for moisture-lovers, a mix that holds water evenly instead of in random pockets.

How to shop this Soil & Substrates range

Start by sorting each plant into jungle, terrarium, arid or semi-hydro territory, then choose either a ready-made houseplant mix or a base plus components. Repot in active growth, let excess water drain fully, and use the substrate to make drying speed predictable rather than a permanent surprise.
