Succulent cuttings rot before they root more often than any gardener expects. The difference between a mushy leaf and a plump new rosette usually comes down to the concentration of indole-3-butyric acid (IBA) you apply. Too strong a dose burns the delicate stem tissue; too weak a formula does nothing. That is why the best rooting hormone for succulents uses a low IBA percentage—typically 0.1% to 0.5%—and a medium that clings without drowning the cut.
I’m Mohammad Maruf — the founder and writer behind Gardening Beyond. I’ve spent years dissecting propagation chemistry, comparing IBA concentrations, cytokinin ratios, and carrier gel viscosities across dozens of brands, and cross-referencing thousands of owner reports on what actually triggers root emergence on fleshy cuttings.
This guide filters down the options so you can pick the exact formula that works for your propagation style. Whether you prefer a gel that seals the cut, a powder for dusting, or a liquid drop for water rooting, we’ve covered the options to find the ideal rooting hormone for succulents.
How To Choose The Best Rooting Hormone For Succulents
Succulent stems and leaves are thicker and more water-dense than most houseplant cuttings. That cellular structure demands a lighter touch with synthetic auxins. Choosing the wrong concentration or formula can kill the cutting before the first root nub appears. Focus on these three factors.
IBA Concentration — The Danger Zone Above 0.5%
Indole-3-butyric acid (IBA) is the active ingredient in virtually every commercial rooting hormone. Standard powders for woody shrubs pack 0.8% to 1.0% IBA. On a succulent, that strength scorches the pithy stem core and causes a brown ring that stops root emergence cold. Look for formulations labeled 0.1% IBA (Hormex #1 level) or up to 0.5% IBA (like the Cloning Gel). The lower percentage encourages cell division without necrotizing the flesh.
Carrier Type — Gel, Powder, Liquid, or Paste
Each carrier changes how the hormone adheres and how long it stays active. Gels seal the cut and prevent air pockets from forming at the base of the stem — excellent for single-stem succulent cuttings. Powders are messier but work well if you dip and then shake off the excess. Liquids are ideal for water propagation because they mix directly into the reservoir. Pastes (keiki paste) are designed for node stimulation on orchids and monsteras, but they use cytokinins rather than auxins, so they are not a direct substitute for a true rooting hormone on fresh succulent cuttings.
Added Nutrients and Anti-Fungal Properties
Some formulations include vitamin B-1 (thiamine) to reduce transplant shock or trace nutrients to support early growth. While not essential, these extras can improve survival when rooting in plain tap water or dry succulent mix. Anti-fungal additives like sulfur or copper are less critical indoors but matter if you propagate outdoors where soil-borne pathogens attack the cut surface.

In‑Depth Reviews
1. Hormex Rooting Powder #1 (0.10% IBA)
The Hormex #1 formulation sits at exactly 0.1% IBA — the sweet spot for succulent and other soft-tissue cuttings. Many rooting powders aimed at woody ornamentals push 0.8% or higher, which burns through the watery interior of a jade or echeveria stem. This powder gives the cutting just enough auxin signal to initiate root cell division without the chemical burn that causes dieback.
You receive a full pound of powder, which is far more product than most hobbyists will use in several seasons. The low concentration also makes it safer for beginners who might accidentally leave the cutting dipped too long. Simply dip the moistened stem base into the powder, tap off the excess, and plant into a dry succulent mix. The powder clings well to dry surfaces but dissolves quickly once the medium is watered.
One caveat: the powder can cake if stored in a humid environment. Keep the lid sealed tight and add a silica gel pack inside the container if you propagate in a greenhouse or indoor grow tent. The large size means you can afford to portion some into a smaller shaker bottle for daily use without risking contamination of the main supply.
What works
- Low 0.1% IBA concentration is ideal for delicate succulent stems
- Bulk pound format offers outstanding value for frequent propagators
- Easy to apply with the dip-and-tap method
What doesn’t
- Powder can clump in humid storage conditions
- Not compatible with water propagation since powder washes off
2. Root Drops – Liquid Rooting Hormone
Root Drops shifts the paradigm entirely: instead of coating the stem, you add the hormone directly to the propagation water. Two drops per cup of water is the recommended dose for succulent cuttings that root in a glass jar or vase. The liquid formula disperses evenly, so every millimeter of the submerged stem receives the same auxin concentration without the risk of over-application at the cut site.
This method excels for pothos, monstera, and philodendron, but it works just as well for succulent stems that prefer to root in water first. The all-natural formulation includes vitamins that reduce transplant shock when you eventually shift the rooted cutting into soil. Because the hormone stays in solution, you must refresh the water every 4-5 days to maintain potency — that slightly increased maintenance is a tradeoff for precision control.
The 4-ounce bottle delivers hundreds of doses, making it economical even at a mid-range upfront cost. For anyone who primarily propagates in water or semi-hydro media like leca and pon, this is the most category-specific tool available.
What works
- Perfect for water, leca, and moss propagation methods
- Precise dosing eliminates the chemical burn risk
- All-natural formula with vitamins reduces transplant shock
What doesn’t
- Requires a strict water-change schedule every 4-5 days
- Not the best choice for direct-to-soil propagation
3. Clonex Rooting Gel (100ml)
Clonex is the gel that serious propagators reach for when they need a physical barrier plus hormonal stimulation. The gel consistency is thick enough to coat a succulent stem end completely, forming a protective seal that prevents air from entering the vascular tissue. This seal is valuable for cuttings with thicker stems — think jade, portulacaria, or adenium — where the exposed pith can dehydrate within hours if left uncovered.
The IBA concentration in Clonex is higher than what Hormex #1 delivers, so it works faster on species that respond aggressively to auxin. For the most tender succulent varieties (lithops, haworthia, or delicate crassula types), you should use a very light dab — just enough to film the cut surface. The gel does not drip or run, which keeps the application zone exactly where you want it without accidentally dosing the leaf scars higher up the stem.
The 100ml bottle lasts through dozens of propagation sessions even with regular use. Once opened, store the bottle upright in a cool spot to prevent the gel from thinning in heat. If you prefer one product that handles everything from woody cuttings to soft succulent stems, Clonex provides the versatility without needing multiple bottles on the shelf.
What works
- Gel seals the cut and prevents stem dehydration
- Strong IBA formula speeds root initiation on responsive species
- No mess or drip during application
What doesn’t
- Higher IBA concentration can burn the most delicate succulents if over-applied
- Gel may thicken in cold storage and become hard to squeeze
4. Cloning Gel with Rapid Rooter (0.5% IBA)
This gel splits the difference between the ultra-low Hormex #1 and the mid-strength Clonex by using a 0.5% IBA concentration. It also includes vitamin B-1 (thiamine), which helps the cutting manage stress during the first week after separation from the mother plant. The dye-free formulation avoids staining leaves or fingers — a minor but welcome detail for anyone who handles multiple cuttings in one session.
The vitamin B-1 content matters most when rooting succulents in cooler environments or during winter dormancy windows. Thiamine supports the energy metabolism of the cutting while it lacks roots to absorb nutrients from the soil. Combined with the moderate IBA concentration, this gel gives a gentle push rather than a hard chemical jolt, making it a safe choice for mixed batches of succulent and tropical cuttings.
Because the gel has a slightly thinner consistency than Clonex, you need to apply it carefully and let it cling for a few seconds before inserting the cutting into the medium. The thinner gel also penetrates small cracks in calloused leaf cuttings better, which can help coax roots from leaves that have already sealed over. For budget-conscious propagators who still want the benefits of a gel carrier and added vitamins, this option delivers solid results without stretching the wallet.
What works
- Vitamin B-1 reduces transplant shock and supports early energy needs
- Dye-free formula keeps hands and foliage clean
- 0.5% IBA is a safe middle ground for most succulent varieties
What doesn’t
- Gel consistency is thinner and may drip off vertical stems
- Not ideal for water propagation since it washes off quickly
5. Berkland Keiki Paste (0.5 oz)
Keiki paste operates on a different biological pathway than IBA-based rooting hormones. It uses cytokinins — hormones that stimulate shoot and bud formation rather than root growth. For succulent propagation, this means you don’t apply it to a fresh cutting. Instead, you dab a rice-grain-sized amount onto a dormant node on an established plant to trigger a new offset or branch. On succulents like echeveria or graptopetalum that produce pups from the stem, this paste can accelerate offset production.
The 0.5-ounce jar from Berkland claims coverage for over 100 nodes, and that number feels accurate given how little paste each application requires. The paste stays put after application without running down the stem, so you can target specific nodes on a tall succulent stalk. Results typically appear within 2-4 weeks if the plant is actively growing and receiving adequate light.
The critical distinction: this is not a replacement for a rooting hormone if you are starting from a bare cutting. The cytokinin signal tells the plant to grow leaves or pups, not roots. Pair it with a rooting hormone like Clonex or Hormex on the cut end to get both root initiation and new shoot development simultaneously. For experienced propagators looking to maximize yield from a single mother plant, the combination of a rooting gel and keiki paste creates a powerful one-two punch.
What works
- Highly effective at stimulating dormant nodes on established succulents
- Small jar covers over 100 application sites
- Paste consistency stays in place without dripping
What doesn’t
- Cytokinins promote shoots, not roots — does not replace true rooting hormone
- Results depend heavily on the plant being in active growth phase
Hardware & Specs Guide
IBA Concentration — The Active Ingredient
Indole-3-butyric acid (IBA) is the synthetic auxin that triggers root initiation. For succulents, keep the concentration between 0.1% (like Hormex #1) and 0.5% (like the Cloning Gel). Concentrations above 0.5% risk burning the fleshy stem tissue. Powders, gels, and liquids all carry IBA, but the carrier affects how much of the hormone actually reaches the cambium layer. Gels offer the most controlled delivery, while liquids provide even distribution in water propagation.
Carrier Medium — How the Hormone Delivers
Each carrier serves a distinct propagation style. Powder coats the stem surface but washes off in water. Gel forms a protective collar around the cut and stays put in soil. Liquid dissolves completely into the propagation medium, requiring regular water changes to maintain potency. Paste (keiki paste) uses a cytokinin base instead of an auxin base, so it is designed for node stimulation rather than root generation from cuttings. Match the carrier to your propagation method rather than trying to force one format into a mismatch.
