Keiki Paste vs Keiki Booster Spray: Which Grows More?
If you've shopped for a way to force new growth on your orchids, you've probably run into two very different formats: a thick paste you dab on a single node, and a liquid or spray you mist over the whole plant. They sound like they do the same thing, but keiki paste vs keiki booster spray is really a question of precision versus general vigor. Paste is a targeted, high-contact application that reliably wakes up a specific node to make a keiki. Booster sprays and liquids — often seaweed-based blends — spread a lower dose across the whole plant to support overall growth, and only sometimes trigger a keiki. Here's how each actually works, and which one belongs in your routine.
Two Formats, Two Philosophies
Keiki paste is a concentrated cytokinin (typically BAP) in a lanolin or cream carrier. Because it's a paste, it does two things a liquid can't: it delivers a strong, localized dose exactly where you want new growth, and it stays put on the node — clinging through waterings so the hormone stays in contact with the tissue for days. That high, sustained, targeted contact is why paste is the reliable choice for deliberately cloning a chosen node.
Keiki booster sprays and liquids come in a few flavors. Some are dilute cytokinin solutions; many popular "boosters" are seaweed or kelp extracts, which naturally contain a mix of growth substances — auxins, cytokinins, and gibberellins — plus micronutrients. You dilute them and either spray the foliage or water them in. The point of a spray is breadth: supporting root development, waking back bulbs, and encouraging general vigor across the whole plant rather than forcing one specific node.
So the honest framing isn't "which is stronger" — it's targeted cloning (paste) versus whole-plant support (spray). They're solving different problems.
Where Paste Wins: Reliable, Targeted Cloning
If your goal is "I want a keiki from this node," paste is the better tool, for three reasons:
- Dose and contact. A dab of paste puts a high local concentration of cytokinin directly on the scored node and holds it there. A spray delivers a much lower dose that mostly lands on leaves and runs off.
- Placement control. With paste you choose the node — a lower node for a keiki, a higher node for a bloom spike — and treat only that one. A spray hits everything indiscriminately.
- Water resistance. A water-resistant paste survives your normal watering schedule. A foliar spray is gone with the next mist or rain and has to be reapplied on a schedule.
This is why nearly every "how to clone your orchid" tutorial reaches for paste. When you want a predictable result at a specific spot, concentration and staying power beat broadcast coverage.
Where a Spray or Liquid Fits
Booster sprays and liquids aren't a worse paste — they're a different job, and a legitimate part of a propagation routine:
- General vigor and roots. Seaweed-based products are widely used to start the growth cycle in spring, support root development on seedlings and divisions, and encourage new growths from back bulbs.
- Whole-collection maintenance. A dilute foliar feed is easy to apply across many plants at once — useful upkeep, not targeted cloning.
- Supporting a keiki after it forms. Once paste has started a keiki, gentle overall nutrition helps it grow out.
The catch: because a spray spreads a low dose across the whole plant, it's unreliable for producing a specific keiki. It may nudge a node, or it may just green things up. If your aim is a clone from a chosen point, that unpredictability is exactly what you don't want.
Side-by-Side Comparison
| Feature | Keiki Paste | Keiki Booster Spray / Liquid |
|---|---|---|
| Typical active | Concentrated cytokinin (BAP) | Dilute cytokinin or seaweed blend (auxins + cytokinins) |
| Application | Dab on one scored node | Mist foliage or water in |
| Dose at the node | High, localized | Low, spread out |
| Stays put? | Yes — water-resistant | No — reapply on a schedule |
| Best at | Cloning a chosen node reliably | Whole-plant vigor, roots, upkeep |
| Produces a specific keiki? | Reliably, with prep | Occasionally, unpredictably |
| Precision | High | Low |
What We Recommend
If your goal is to actually clone a plant — get a keiki from a node you choose — paste is the tool that does it reliably, and a good jar lasts a long time because you use so little per node. A booster spray is a fine complement for overall vigor, but it's not a substitute when you want a predictable result at a specific spot.

Frequently Asked Questions
Is keiki paste or a booster spray better for making a keiki?
Paste, if your goal is to clone a specific node. It delivers a high, localized dose of cytokinin and stays on the node through watering, which makes it far more reliable than a spray. Sprays spread a low dose across the whole plant and only occasionally trigger a keiki at any given node.
What is a keiki booster spray made of?
It varies. Some are dilute cytokinin solutions; many popular boosters are seaweed or kelp extracts that naturally contain a mix of auxins, cytokinins, gibberellins, and micronutrients. They're aimed at general vigor and root support more than targeted node cloning.
Can I use both a paste and a spray?
Yes — they complement each other. Use paste to force a keiki from a chosen node, and use a dilute booster or seaweed feed for overall plant vigor and to help a new keiki grow out. Just don't expect the spray to reliably produce a keiki on its own.
Why does paste work better on a single node?
Because cloning depends on concentration and contact time. Paste puts a strong dose right on the scored node and holds it there for days, while a spray delivers a diluted amount that mostly lands on foliage and washes off. For a predictable result at one spot, paste wins.
Do I still need to score the node if I use paste?
Yes. Whatever the format, cytokinin has to reach the living cells at the node. With paste you expose and lightly score the node first so the hormone can make deep contact — that prep is a big part of why paste is so reliable.
