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.

A Comprehensive Balanced History of the Guadalcanal Campaign -- Must Read!
Format: Hardcover
I've read a number of good books on the Guadalcanal campaign, and always thought that "Neptune's Inferno" by Hornfischer was the absolute best. I was wrong. Although Hornfischer does a superb account of the Navy and its travails and triumphs, Inferno doesn't delve deeply into the Marine (and Army) land battles. This book does both. Moreover, it provides a continuous timeline of both, and does so in such a way that the reader better understands both as related actions. For instance, I was never really aware that for the first three and a half months the Americans controlled the seas during daylight, and the Japanese at night (sounds a little like Viet Nam). The November 13 sea battle between Americans and Japanese -- in which US cruisers took on Japanese battleships and two American admirals died -- was in fact a clash of a major last ditch effort by the Japanese to reinforce their troops and destroy Henderson Field, which would have allowed them to control the seas both day and night. By that time there had been multiple bloody battles ashore between the Marines and Japanese, with the balance favoring the Marines, but if the Japanese had wrested control of the airfield and seas that would have been old history. The book includes a good view from the Japanese perspective, and some little known historical tidbets as well, e.g., Guadalcanal received its name from the Spanish home town of a ships officer who accompanied Spanish explorer Don Alvaro Medana, who discovered the island during a 1568 expedition to discover the fabled King Solomon's gold mines. Who knew? :-) Bottom line: I highly recommend this book, both for its balanced coverage of the entire campaign, land and sea, and even more for its integrated narrative -- you know what was taking place (or had taken place) on almost a day-by-day basis, which allows the reader to fully appreciate how actions ashore influenced those at sea, and vice versa. IMO, a must read, even for those who thought (like me) that they knew it all!

The Island Of Death
Format: Hardcover
On August 7th, 1942, American Marines stormed ashore on Guadalcanal. What lay before them was a six-month odyssey of fighting against the best of what the Japanese had to offer. In this fine book, author Joseph Wheelan describes the battle that turned the tide in the Pacific War. The Japanese had started construction of an airfield on Guadalcanal. If completed, Japanese aircraft would be able to harass American convoys and threaten Australia. The Americans seized the airfield and eventually, planes from the Cactus Air Force began attacking the Japanese. Throughout the book, the reader learns about all phases of the Guadalcanal campaign, including the battles of Alligator Creek and Bloody Ridge. On the sea, the Americans and Japanese slugged it out at Savo Island, as well as the great naval battles of November, 1942. Names such as Chesty Puller, John Baslone, "Archie" Vandegrift, Joe Foss, and "Bull" Halsey became household names in the United States. Each side lost many men, ships, and planes, but the tenacity and, finally, the industrial might and the ability to rapidly replace losses, led the Americans to victory. Never again would the Japanese regain the offensive in the Pacific War. "Midnight in the Pacific" is a very good book, and the author has done a good job of describing all of the main points of the battle. Each chapter is broken down into a single month's worth of action, and the narrative is well-written. Highly recommended.

Good Narrative History
Format: Hardcover
The account of the Guadalcanal campaign was well-written. It has several good maps but it falls short with the two carrier battles associated with the action. There should have detailed maps for the Battle of the Eastern Solomons and the Battle of the Santa Cruz Islands. Aside from this shortcoming, the book provides an excellent, readable history of a crucial confrontation between the US and Japan.

A Very Thorough Accounting of One of the Most Savage Battles of World War 2
Format: Kindle
My father served in the United States Marine Corps during World War 2 and fought in the first offensive battle by the US during the war, the battle for the island of Guadalcanal. He was seriously wounded there and evacuated back to the states where he spent a year in a naval hospital. As a result, I have read many of the books about this battle. This book was particularly interesting because the author described the battle from the perspective of both the allied forces and the Japanese, drawing from historical records and other books. It was a very thorough accounting and demonstrated what a monstrous battle this was. I only wish my father were still alive so that I could have discussed it with him. His experience at Guadalcanal was not something he would often talk about, but considering savagery of what he saw and endured, I understand. If you are interested in Guadalcanal, I recommend this book.

Excellent book on the Campaign!
Format: Hardcover
I highly recommend this book! I have read many books on the Guadalcanal Campaign and I rate this one at the top. It has just the right blend of stragity and personal accounts to keep the story interesting. It is actually a real page-turner, which is rare for a non-fiction work. Wheelan writes in a style that reminds me of the books I read in my teens by Cornelius Ryan and John Toland, which captured my interest in WWII and history. The book jumps right into the invasion, no multiple chapters concerning the planning and build up, but this info is covered later. All phases of this campaign are covered; ground, air and sea. The maps are okay. There are never enough. The author skims over much of the U. S. Army battles after the Marines are relieved, but that seems to be a trend in all of the books on Guadalcanal that I have read. Overall, this is an excellent book for those who want to learn about the campaign and those who need a re-fresher after reading Starvation Island and Guadalcanal by Frank in years past.
