Keiki Paste vs Rooting Hormone: Which Is Better for Plant Propagation?
If you're trying to propagate orchids or houseplants and you've stumbled onto the keiki paste vs rooting hormone debate, you're not alone. Both products help plants reproduce, but they work in completely different ways — and using the wrong one for your situation can mean waiting months for results that never come. Here's the real difference between keiki paste and rooting hormone, and exactly when to use each one.
What Is Keiki Paste and How Does It Work?
Keiki paste is a cytokinin-based compound — typically containing benzylaminopurine (BAP) — that triggers dormant growth nodes on a plant to develop into a new plantlet called a keiki (Hawaiian for "baby" or "child"). Instead of stimulating roots, keiki paste stimulates cell differentiation at the shoot level. You're essentially telling a dormant node: wake up and grow.
The primary use case is orchids, where keiki paste is applied directly to a node on a flower spike to produce a genetically identical baby plant. But it works on many houseplants too — pothos, philodendrons, monsteras, and hoyas all respond well to cytokinin applications anywhere there's a visible node.
Here's the sequence of events when you use keiki paste:
- You identify a healthy node (the bump or eye on a stem or flower spike)
- You apply a small amount of paste directly to the node with a toothpick or included applicator
- The cytokinin disrupts the plant's apical dominance, redirecting growth energy to that node
- Within 2–6 weeks, a new shoot or plantlet emerges
- The keiki continues growing until it develops its own root system (usually 2–4 more months)
- Once the keiki has roots at least 1–2 inches long, you can safely separate and pot it
The critical distinction: keiki paste creates a whole new plant (shoot first, then roots). It does not help an existing cutting grow roots — that's a different biological process entirely.
What Is Rooting Hormone and How Does It Work?
Rooting hormone is an auxin-based compound — most commonly indole-3-butyric acid (IBA) or naphthaleneacetic acid (NAA) — that stimulates root cell development at a cut stem surface. Where cytokinins say "make shoots," auxins say "make roots."
Rooting hormone is used on cuttings: you take a stem cutting from a plant, dip the cut end in rooting hormone powder, gel, or liquid, then plant it in a moist growing medium. The auxin concentration at the wound site signals root cells to proliferate faster than they would on their own, turning a cutting that might naturally take 6–8 weeks to root into one that roots in 2–3 weeks.
Common forms of rooting hormone:
- Powder: Easiest to use, longest shelf life. Dip the cutting, shake off excess, stick in medium.
- Gel: Clings better to the stem and may stay more concentrated at the wound site.
- Liquid concentrate: Can be diluted for a soak or used as a root stimulator soil drench around newly potted cuttings.
What rooting hormone cannot do: create new shoots, trigger nodes, or produce keikis. It accelerates root development on cuttings that already have leafy growth and a fresh cut end.
Keiki Paste vs Rooting Hormone: Head-to-Head Comparison
| Feature | Keiki Paste | Rooting Hormone |
|---|---|---|
| Active ingredient | Cytokinin (BAP) | Auxin (IBA/NAA) |
| What it creates | New shoot/plantlet | Roots on existing cuttings |
| Primary use case | Orchids, node propagation | Stem cuttings |
| Application method | Directly to node on mother plant | To cut end of removed stem |
| Result timeline | 2–6 weeks to see shoot growth | 1–4 weeks for roots |
| Plant stays attached during process? | Yes, until keiki is ready | No — cutting is removed first |
| Works on orchids? | Yes — the preferred method | Not applicable |
| Works on pothos/philodendron? | Yes, via node stimulation | Yes, via cuttings |
| Produces genetic clone? | Yes | Yes |
| Risk of failure | Low with proper application | Moderate (cutting may rot) |
The most important takeaway: these products are not interchangeable. They solve different propagation problems. If you have an orchid you want to propagate, rooting hormone won't help — orchids don't root successfully from cuttings the way most houseplants do. You need keiki paste. If you have a pothos stem cutting sitting in water, keiki paste applied to an already-severed stem won't do anything useful — you need rooting hormone (or just patience).
When to Use Keiki Paste
Propagating orchids — This is the scenario keiki paste was designed for. Monopodial orchids like Phalaenopsis can't be divided like sympodial types (Cattleya, Oncidium). Keiki paste applied to a node on a spent flower spike is the standard, proven method for getting a new Phalaenopsis plant without harming the mother.
Node propagation without cutting — If a pothos has a long bare stem with multiple nodes but you'd rather not cut it, keiki paste lets you stimulate those nodes while the stem stays attached. The mother plant feeds the developing keiki the whole time.
Multiple simultaneous propagation points — You can apply keiki paste to several nodes on one plant at the same time, potentially producing multiple babies from a single mother plant in one season.
Rare or irreplaceable plants — Since the keiki grows attached to the mother until it's developed enough to survive on its own, there's no risk of losing a cutting to rot or drying out. This matters a lot when you're working with an expensive orchid or a hard-to-find cultivar.
When to Use Rooting Hormone
You already have cuttings — If you've already taken stem cuttings and want to improve their rooting success rate and speed, rooting hormone is the right tool.
Species that propagate readily from cuttings — Pothos, wandering dude, coleus, basil, tomatoes, and most tropical foliage plants root well from cuttings and benefit from rooting hormone.
Woody plants and shrubs — Rooting hormone is especially useful for semi-hardwood and hardwood cuttings from shrubs and trees (roses, hydrangeas, boxwood, fruit trees), which need more chemical stimulation to root successfully.
High-humidity propagation environments — Many rooting hormone powders include a fungicide, which helps prevent stem rot in humid propagation chambers — a real practical benefit.
Can You Use Both Together?
In some workflows, yes. A few advanced growers use keiki paste to generate a keiki, and once that keiki is separated and potted up, apply a very diluted auxin solution as a soil drench to help the young plant establish roots more quickly in its new pot. This is a legitimate technique — just rarely necessary. Keikis typically establish roots well once separated, especially if potted in a well-aerated orchid mix and kept in appropriate humidity.
What you should never do: apply keiki paste to a cut stem expecting it to root, or apply rooting hormone to a node on an intact plant expecting a keiki. These compounds work on entirely different biological pathways.

Frequently Asked Questions
Can I use keiki paste on a pothos instead of rooting hormone?
Yes, but they produce different results. Keiki paste applied to a pothos node will stimulate that node to grow a new shoot while the vine remains attached to the mother plant. Rooting hormone is used on a cutting that's already been removed. If your goal is node propagation without cutting, keiki paste is the right choice. If you already have cuttings ready, use rooting hormone or simply root them in water.
How long does keiki paste take to work on orchids?
Most growers see visible bud swelling at the node within 2–4 weeks, with a recognizable keiki (with small leaves) emerging by weeks 4–8. Root development on the keiki usually takes another 2–4 months before it's ready to separate from the mother plant. Results vary with species, temperature, and light level. Warmer conditions (68–80°F) and bright indirect light accelerate the process considerably.
Does keiki paste work on plants other than orchids?
Yes. While orchids are the most common use case, keiki paste works on any plant with accessible nodes and a response to cytokinin. Popular non-orchid applications include pothos, philodendron, monstera, hoya, and even some succulents. Berkland Keiki Cloning Paste is specifically formulated and tested for use across this broader range of houseplants.
What's the difference between keiki paste and cloning gel?
Cloning gels are typically auxin-based products (rooting hormone in gel form) used on stem cuttings. Keiki paste is cytokinin-based and applied to intact nodes on the mother plant. Some products use the word "cloning" loosely — if the directions say to dip a cutting, it's a rooting product, not a keiki paste.
Is keiki paste safe for all orchid types?
Keiki paste is most reliable on monopodial orchids like Phalaenopsis (moth orchid). It can also work on Dendrobium and some Epidendrum species. Results are less predictable on sympodial orchids (Cattleya, Oncidium), which are typically propagated by division rather than keiki production. For Phalaenopsis — by far the most common home orchid — keiki paste is the go-to propagation method.
