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.

Quality booties that don’t fall off
Size: 0-3 Months Infant, Color: Ivory Sherpa, Size: 0-3 Months Infant, Color: Ivory Sherpa
Love these booties - super cute, quality made, and they don’t fall off even when we’re passing the baby around. We put these on without socks; the booties are not lined with fleece but has a firm sole. I got the 0-3 months size for my 3 month old and there’s still a little bit of room to grow. Easy to put on baby’s wiggling feet and there are two snap buttons to select for fit. There’s really no grip on these so not sure how they hold up for walking. The fleece is plush and seems to keep baby’s feet warm.
