Quick answer: what is Molly's Succulent Mix?

  • For: succulents, cacti, bonsai, Haworthia, Echeveria, Sedum, Jade, and any arid-environment plant.
  • What's in it: high-mineral gritty blend of pumice, lava rock, and crushed bark. Low organic matter by design.
  • Why it works: succulent roots are built to drink fast and dry out fast. The gritty structure drains in seconds and holds zero standing water, so roots don't rot.
  • Pre-rinsed and pH-balanced straight from the bag. No salt flush required.
  • Bonsai-safe. The grit profile matches what serious bonsai growers blend by hand from akadama, pumice, and lava.

More plant-specific guidance: Ultimate guide to growing succulents indoors, Potting soil vs potting mix.

Succulents and cacti evolved in arid, mineral-rich environments where water moves through gritty substrate in seconds. Their roots are built to drink fast and dry out fast. Standard potting soil holds moisture for days, suffocates the roots, and rots them from the bottom up. The fix is a high-mineral, low-organic, gritty mix.

Molly's Succulent Mix is engineered to mimic native desert and rocky-slope substrates. A blend of pumice, lava rock, and a small amount of organic matter that drains in seconds and forces the soak-and-dry watering rhythm succulents need.

The gritty-mix philosophy

Most "succulent soil" sold at garden centres is regular potting soil with sand mixed in. That's not what these plants want. The right mix is roughly 70% mineral aggregate (pumice and lava rock) and 30% structural organic (coir, charcoal). Water hits the surface and runs through within seconds. Roots get a brief, intense drink, then dry conditions for the next 1 to 2 weeks. That's how succulents stay alive in pots.

What's in the bag

  • Pumice (volcanic, lightweight): the mineral backbone. Holds a tiny amount of water inside its porous structure, but lets the rest drain freely.
  • Lava rock (red lava): chunky drainage and heat retention. Roots love the warmth differential it creates.
  • Coir fiber (small percentage): just enough organic to retain a little humidity and prevent the mix from drying to a brick. Not enough to compromise drainage.
  • Horticultural charcoal: filters salts from tap water (succulents are surprisingly sensitive to mineral buildup).
  • Calcitic limestone (trace): buffers pH to the slightly alkaline range (6.5 to 7.5) most desert succulents prefer.

Low peat content, no worm castings (succulents don't want a nutrient flush), no commercial fertilizer. The whole mix is intentionally lean.

Plants this is for

Designed for succulents and cacti:

  • Echeveria, Sedum, Crassula (jade), Sempervivum: the classic rosette succulents.
  • Haworthia, Gasteria: they prefer slightly more shade but want the same gritty drainage.
  • Aloe (vera and others): medicinal succulents, this mix prevents the rot they're prone to in heavier soils.
  • Most cacti: Mammillaria, Echinopsis, Opuntia, San Pedro, golden barrel.
  • Lithops (living stones): require fast drainage to stay alive year-round; this mix is well-suited.
  • Bonsai with high drainage needs: juniper, pine, and certain deciduous bonsai work well.
  • Caudex plants: Adenium, Pachypodium, and other swollen-stem species that need fast drainage at the base.

Not for: tropical "succulent-looking" plants like Hoya, Christmas cactus (Schlumbergera), or Easter cactus, which actually prefer humidity-retaining mixes. For those, use Molly's Aroid Mix.

Watering with gritty mix

The right rhythm: soak and dry. Water deeply, then wait until the mix is bone-dry before watering again.

  1. Wait until the top 2 to 3 inches feel completely dry. For most succulents in standard 4 to 6 inch pots, that's every 10 to 21 days indoors.
  2. Water until liquid runs clearly out the drainage holes. Don't dribble. Soak.
  3. Discard any water in the saucer. Do not let the pot sit in standing water.
  4. Wait. The plant will let you know when it's thirsty (slight wrinkling of leaves, lighter pot weight).

In winter, water roughly half as often. Most succulents go dormant or semi-dormant.

FAQ

Why is this so heavy compared to other succulent soil?

Because it's mostly minerals, not peat or coco coir. The weight is what makes it work. Light bag means light drainage, which is the opposite of what succulents need.

Can I use this for bonsai?

For tropical bonsai, no, they want a moisture-retentive aroid-style mix. For drought-tolerant bonsai (juniper, pine, certain deciduous species), yes, this mix or a 50/50 blend with finer organics works well.

Will the mix break down or stay porous over time?

Stays porous. The mineral components (pumice, lava rock, charcoal) don't decompose. The small organic fraction breaks down slowly. Most succulents in this mix can go 2 to 3 years before repotting.

Should I add fertilizer?

Sparingly. Succulents are slow growers and don't need much. A diluted (~1/4 strength) cactus-specific fertilizer once during the growing season (spring) is plenty for most species.

Not eczema skin friendly
Size: 5.5 Ounce (Pack of 1), Size: 5.5 Ounce (Pack of 1)
Since I didn’t remember which sunblock spray I had previously purchased (that was super awesome), I got this one with a few other ‘kid’ sunblock spray and stick. I had grabbed this one for a splash pad birthday party this weekend only to find out it’s messy and not eczema skin friendly. Either we got a defective bottle or it’s just the way it sprays: runny goops of sunscreen that takes awhile to dry properly (see photo). And when it dries it really does stick onto your skin as advertised (aka not breathable, pore clogging, will irritate sensitive/eczema prone skin). My youngest has eczema prone skin (that’s been flare up free for 3 years) had a severe break out on her arms after using this. And even for the sake of photo demonstration for this post my own sensitive skin got red/irritated. So does it stick-yup. Is it messy? Definitely. Easy to apply? No (your kiddos have to stay put until it dries). Did it provide sun protection? Maybe…? Sensitive skin friendly? No. Eczema skin approved? Definitely not. Recommended? Nope. We threw it away and requested a refund.

10/10 sunscreen spray
I have combination skin that can get oily throughout the day, and I was excited to try the Naked Sundays SPF 50 Golden Glow Shimmer Setting Spray because I loved the idea of having sunscreen and a setting spray in one product. The first thing I noticed was the packaging. The ombre gold to purple container looked so luxurious and intentional. The spray mist was fine and even, making it perfect to apply over my makeup with a smooth finish. I love the scent. It smells fruity and delicious, which is such a refreshing change from the typical sunscreen smell that many other sunscreen sprays have. Overall I loved this spray and it exceeded my expectations. It kept my makeup looking fresh all day long and gave my skin a beautiful, glowing finish. I would definitely recommend and I will 100% be purchasing it again!

Easy Spray Sunscreen with No Greasy Hands & No Harsh Smell
Really impressed with this sunscreen. The spray nozzle makes it incredibly easy to apply without getting my hands greasy, which is a huge plus. It feels lightweight on the skin and doesn’t leave a sticky or heavy residue. One thing I loved is that it doesn’t have that typical strong sunscreen smell, it’s much more subtle and pleasant. I’ve also worn it during workouts, and it didn’t run into my eyes or cause any stinging when I was sweating, which is rare for me. It layers well over makeup and gives a nice, subtle glow without looking greasy. Overall, it’s convenient, mess-free, and something I’ll definitely keep using for easy SPF reapplication throughout the day.

Nozzle doesn’t work on a $30 sunscreen!!
I’d give this zero stars if I could. While I imagine the glow is amazing, I wouldn’t know because the spray nozzle on this doesn’t work. Not a single spray. I’m assuming it’s clogged with glitter and I’ve tried everything unclog it but for $30, I shouldn’t need to decant or switch this into another bottle. I will end up doing that, so I can hopefully use it, but my complaint remains. It is also not eligible for returns or replacements. Cute but useless packaging.
