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.

emotional. heart warming
Format: Kindle
It was a good book, the relationships with the friends a main part of it. I do wish there was more spice because she slow burned us to death and then gave us this a closed door. Lol But it was well written and poignant.

I am begging you to read this book
Format: Kindle, Format: Kindle
A group of women trapped in a temple during an invasion who pretend to be sacred priestesses to avoid being killed and it actually works. That is the setup. That is the whole brilliant premise behind the title and honestly it had me from the first chapter. But what keeps you reading is Edie. She is not a chosen one, not a warrior, not a princess. She is older, she has already lived a full complicated life before this story starts, and that history shapes every decision she makes. When everything falls apart and she ends up somewhere she never expected to be, she does not transform overnight. She reads the room, adjusts, and keeps going. It sounds simple but it is so refreshing compared to what fantasy usually gives us. The women around her are just as important. They do not instantly become a perfect found family. They figure each other out slowly, earn each other's trust over time, and what builds between them ended up being one of my favorite things about this entire book. The romance is slow burn done right. Not manufactured tension, not two people being stubborn for no reason. Real yearning, real patience, real payoff. The magic and world building are present without being overwhelming. There is a nature and ritual element running through everything that gives the story a distinct feel without stopping to explain itself every five minutes. The final stretch of this book is something I was not prepared for. By that point you are so invested in these characters that everything carries weight it would not have had on page one. If you want wall to wall action this is not your book. If you want fantasy that actually makes you feel something, this is exactly your book. One of my favorite reads in a long time. When I was finished reading it, I just kinda sat there... trying to savor every moment of it. Five stars. I recommend this to everyone I know.

BLEW ME AWAY! Loved every moment
Format: Kindle, Format: Kindle
My new FAVORITE BOOK! Priestess by Kara Reynolds blew me away from start to finish. This is a beautiful story about feminine power, sacrifice, self-worth, friendship, found family, healing and love. And the SLOW burn romance is excruciating and exquisite in the best way (“I am beyond temptation, I have been tempted and I have surrendered”). It was especially wonderful to find a fantasy novel with an FMC in her late 30s that is very relatable. It explores the topics of finding love later in life, fertility and the struggles women have with attaching self-worth with motherhood (My mother says all women are mothers in different ways, that we all give birth, just not all to children. Some women give birth to revolutions, to movements, to sanctuary, to art, to brilliance.”) GAHHH love this. I felt so seen. The twists and turns had me on the edge of my seat, dying to turn the pages faster to know what happens and at the same time wanting to slow down and enjoy Reynolds beautiful prose and savor each chapter. The ending was perfect and the authors note made me cry. I CANNOT wait to read Illuminator and Pilgrimess which will be out April 28th!!!! Kara Reynolds is def on my auto-buy list 💚

Take a jaunt to Tintar, a city of blue abalones and black stone set above the angry sea...
Format: Paperback
Edie is a clever, gutsy heroine, who is lucky to be surrounded by a crew of likewise interesting ladies. Their tender moments in the bath and at the bar alike were very lovely, and the themes of female friendship were refreshing. My favorite parts had to do with the magic of this world, which is very novel. Often there's elemental magic, earth gets the short end of the stick. Not so here. The power of earth in this seaside landscape cannot be underestimated, and I really enjoyed that twist. Earth signs, at least, will rejoice in seeing their element treated with real consideration. All of the scenes of magic and old gods were A+, and I loved the weirdness of the rocks first coming to her in the forest, then erupting from the ground to let her know without a doubt what her strength was, and finally forming majestic creatures to rescue her new home—all based on the women who had supported and loved her. The final conflict was excellent. There was a real sense that Edie was going to sacrifice something that she did not want to let go of, which you don't get that often. (Plus, it was pretty funny when a certain someone got tossed over a wall.) Finally, given the themes of womanhood in this book, I am going to pull a word from the big reviewers' lexicon and say that this book is /timely/. What it says about what women are and are not, how it explores Edie's feelings about her body, were thoughtful and illuminating and, yes, timely and given the political climate we are now in—I will even add /necessary/ to that list. It's a rich, femme-centric fantasy epic that made me think about womanhood (and motherhood) in a new light.

Woman's experience and the power of female friendships
Format: Kindle
This story was amazing, and had several elements currently lacking from the genre. It was mature, wise, experienced, and empathetic. It was wonderfully representative of women's experience, with the bonds and friendships between them serving as the balm for life's hurts. **Spoiler alert/warning: Reynolds tackled SA, infertility, teenage pregnancy, and more. Her representation of infertility is the most true-to-form capture of that awful journey that I've ever seen in literature (AND it wasn't "cured" by the love of the "right" man - something that drives me crazy in 99.99999% of stories that try to touch on infertility). She even included the realness of the older infertile woman's response to the teenage pregnancy in a raw and unfiltered way. Another review said it but I'll back it up: Kara knows. And she shows you that she knows. Thank you for your empathetic writing, Kara Reynolds. Thank you for seeing women and our experiences and representing us on the page. I was touched, moved, inspired, and comforted by the power of female friendships and found family. The romance was gorgeous, even in its predictability. Because it was clear that the true loves of her life were those enduring women who walked life alongside her. Amazing story.
