FAQs
What exactly is the Cactus & Succulent Soil Builder?
A DIY mineral kit you blend into regular potting mix to turn it into fast-draining, airy, cactus/succulent-friendly soil.
How much soil does the Cactus & Succulent Soil Builder kit make?
About 35 L of finished mix when combined with 25 L of potting soil.
What do I mix the Cactus & Succulent Soil Builder kit with?
Use a high-quality peat-based potting mix (no big bark chunks or wood fines). That combo delivers structure + drainage without going waterlogged.
What’s inside—does the Cactus & Succulent Soil Builder kit have fertiliser?
It’s a mineral/aeration blend (think drainage stones and lightweight porous media). No added fertiliser—feed separately if your plants need nutrients.
What’s the perlite percentage?
Perlite is a major component—roughly half the kit by volume—because it keeps the mix open and free-draining.
Why not just use straight “cactus mix” from the hardware store?
Most off-the-shelf cactus soils are still too peaty and compact over time. Soil Builder spikes the potting mix with extra grit and pores so water runs through and roots can breathe.
Can I use the Cactus & Succulent Soil Builder kit by itself with no potting mix?
No. It’s designed to be blended with potting mix. On its own, it doesn’t hold enough nutrients or moisture for healthy growth.
What ratio should I use if I don’t have a full 25 L bag of potting mix?
The kit-to-potting-mix ratio is ~10:25 (0.4:1 by volume). Example: for 10 L of potting mix, add ~4 L of Soil Builder.
Will Cactus & Succulent Soil Builder kit work for both indoor and outdoor plants?
Yep—great in pots indoors or outside. Just adjust watering to conditions (outdoor heat and wind dry pots faster).
Does Cactus & Succulent Soil Builder kit help prevent root rot and fungus gnats?
Yes. Better drainage + lower soggy organic matter = fewer rot issues and less gnat-friendly habitat.
Is the Cactus & Succulent Soil Builder kit suitable for seedlings and cuttings?
Yes—many growers use it for cactus seedlings and succulent cuttings. For tiny seedlings, sift out the very largest bits or top-dress with a finer layer so they seat well.
Will the Cactus & Succulent Soil Builder kit change my soil pH?
It’s designed to be pH-stable when used as directed. Your final pH mostly depends on the potting mix you blend it with and your water source.
What pot type works best with the Cactus & Succulent Soil Builder mix?
Terracotta breathes and pairs perfectly with gritty mixes. Plastic and ceramic work too—just water more carefully since they hold moisture a bit longer.
How often should I water after switching to the Cactus & Succulent Soil Builder mix?
Water deeply, then wait until the mix is dry through the root zone before watering again. In warm seasons that might be weekly; in winter it can stretch to every few weeks. Always let the pot tell you—don’t follow a fixed calendar.
Do I still need fertiliser?
Occasionally, yes. The kit improves nutrient retention (so feeds don’t flush straight through), but it doesn’t supply nutrients itself. Use a gentle, low-nitrogen feed during active growth.
Can I blend the Cactus & Succulent Soil Builder kit with the ready-made DRGT Cactus & Succulent Potting Soil?
You can if you want it even grittier. Add small amounts at a time and test drainage—most folks find the ready-made soil doesn’t need extra unless they’re heavy waterers.
How does the Cactus & Succulent Soil Builder kit compare to adding just perlite or just pumice?
Single ingredients help, but this kit combines several pore-forming minerals with different textures and pore sizes, so it drains fast yet still holds a smidge of moisture where roots can access it.
Is the Cactus & Succulent Soil Builder kit good for Lithops, Haworthia, or other “touchy” species?
Yes—especially species that sulk in peat. For ultra-dry growers (Lithops/Conophytum), go heavier on the mineral side by blending in a bit more kit than usual.
Can I use the Cactus & Succulent Soil Builder kit for bonsai or tropical houseplants?
It’s built for arids. You can use small amounts to open heavy mixes for bonsai or aroids, but they generally want more moisture than cacti.
What size particles are in the Cactus & Succulent Soil Builder kit?
A purposeful mix of coarse and medium granules. If you prefer a very uniform texture, you can sieve to your taste—keep the chunky fraction for bigger pots.
Does the Cactus & Succulent Soil Builder kit compact or break down over time?
Much slower than peat-heavy mixes. The minerals are structurally stable, so the mix stays open longer and repot intervals stretch out.
Can I reuse the mix when I repot?
Usually, yes. Pick out old roots, refresh with ~25–40% fresh Soil Builder, and top up organic content with fresh potting mix if it’s been years.
Is the Cactus & Succulent Soil Builder kit safe for pets and kids?
It’s an inert mineral blend, but it’s dusty—keep out of reach, don’t inhale dust, and wear a mask/eye protection while mixing. Not for consumption.
Any tips to reduce dust while mixing?
Lightly mist the components before blending and mix outdoors or in a well-ventilated area.
Will the Cactus & Succulent Soil Builder kit make my pots lighter or heavier?
Similar or slightly lighter than gravel-based gritty mixes. It won’t weigh a pot down like pure stones, but it’s not as feather-light as straight peat.
Can I use the Cactus & Succulent Soil Builder kit in very humid climates?
Yes—this is where it shines. In humid/coastal spots, the extra airspace helps the root zone dry properly between waterings.
What about very hot, dry summers?
It still works—just water more deeply when you do water, and consider a slightly higher proportion of potting mix (or a mulch/top-dress) to slow evaporation.
Will the Cactus & Succulent Soil Builder kit improve nutrient efficiency?
Yes—the mineral blend increases cation-exchange capacity so fertiliser sticks around longer instead of leaching straight out the drain holes.
Does the Cactus & Succulent Soil Builder kit contain wood chips or compost chunks?
No—avoid chunky wood/compost in the base potting mix you choose. The kit itself focuses on mineral structure.
Can I use the Cactus & Succulent Soil Builder kit for large landscape beds?
It’s designed for pots/containers. For beds, you’ll burn through bags quickly; buy bulk mineral amendments for beds and copy the same principles.
What’s the best way to test if I’ve got the ratio right?
Soak a pot, lift it, and time the dry-down. You want water to run through fast and the pot to feel noticeably lighter within 24–48 hours, with the root zone drying in several days (species and pot size dependent).
Does the Cactus & Succulent Soil Builder kit ship compacted or loose?
It’s bagged as a loose blend. Settling during transit is normal—just fluff it before use.
Storage instructions?
Keep sealed and dry. If it gets wet in storage, let it dry fully before blending so you don’t trap moisture in the bag.
I water heavily—should I tweak anything?
Yes—blend a touch more Soil Builder than the standard ratio for extra margin of safety.
I’m a chronic underwaterer—will this be too dry?
Use the standard ratio and a slightly deeper pot or plastic/ceramic pot. You can also add a bit more base potting mix to hold moisture longer.
Can I combine the Cactus & Succulent Soil Builder kit with akadama, lava rock, or extra pumice I already have?
Sure—advanced growers often tune texture with those. Add small amounts and trial on a few plants first.
Will the Cactus & Succulent Soil Builder kit help with salt build-up from tap water?
Regularly flush pots with plain water until it runs clear. The open structure makes flushing easier and helps prevent crusting at the surface.
Any special potting technique with the Cactus & Succulent Soil Builder kit?
Don’t over-tamp. Backfill gently, tap the sides to settle, water once to seat the mix, and top-dress with decorative grit if you like.
