What Exactly is orchid cloning paste?
At its core, this substance is a specialized horticultural ointment used to stimulate growth in dormant buds. Most gardeners know it by its more common name: keiki paste.
The word “keiki” is Hawaiian for “baby” or “little one,” which is exactly what you are trying to create. It is a thick, lanolin-based ointment infused with concentrated plant hormones.
The primary active ingredient is usually a cytokinin called 6-Benzylaminopurine (BAP). This hormone signals the plant cells to divide and differentiate into new vegetative growth rather than just more flowers.
Because the paste is thick and waxy, it stays exactly where you put it. This allows the hormones to penetrate the specific node you want to activate without washing away during watering.
Think of it as a localized “wake-up call” for the orchid’s dormant energy. It tells the plant that instead of resting after a bloom cycle, it is time to build a brand-new generation.
The Science of Plant Hormones and Nodes
To understand why orchid cloning paste works so well, we have to look at how orchids grow. Most indoor orchids, like the moth orchid, have “nodes” along their flower spikes.
A node is a small, slightly swollen bump on the stem that is protected by a thin, papery scale called a bract. Inside that node sits a tiny cluster of undifferentiated cells.
In nature, these cells stay dormant unless the main growth point of the plant is damaged. The plant usually focuses its energy on the very top of the spike to produce flowers.
When we apply synthetic cytokinins, we override the plant’s natural hormone balance. We are essentially “tricking” the node into thinking it needs to sprout a new plant immediately.
It is a fascinating process that mimics the natural survival instinct of the orchid. In the wild, if a spike is broken, the plant might produce a keiki to ensure its genetic line continues.
Cytokinins vs. Auxins
In the world of plant growth, there is a constant tug-of-war between cytokinins and auxins. Auxins usually encourage root growth and upward height.
Cytokinins, like those found in the paste, encourage lateral growth and leaf production. Balancing these two is what keeps a plant healthy and proportional.
By applying a high concentration of cytokinins to a single spot, you are creating a temporary “growth explosion” in that specific area. It is a very safe and controlled way to manage plant development.
Choosing the Best Candidate for Cloning
Before you start applying your orchid cloning paste, you need to make sure your mother plant is up for the task. Propagation takes a lot of energy from the parent plant.
Never try to clone an orchid that is currently struggling with root rot or pests. The process of growing a keiki is demanding, and a weak plant might not survive the extra stress.
Look for a plant with thick, leathery leaves and a robust root system. If the leaves are floppy or wrinkled, focus on rehabilitating the plant before you try to multiply it.
The flower spike itself should be green and firm. If the spike has already turned brown and crispy, it is too late to use that specific stem for cloning.
I always recommend waiting until the last flower on the spike has faded. This ensures the plant has finished its primary reproductive cycle and can shift its focus to vegetative growth.
The Importance of Hydration
A well-hydrated orchid is much more likely to produce a successful clone. Water your plant thoroughly a day or two before you plan to apply the treatment.
When the plant cells are turgid (full of water), the hormones can move more easily through the tissues. This increases the speed at which you will see the first signs of growth.
If the environment is too dry, the paste might dry out before the hormones can be absorbed. Maintaining a steady humidity level is key during this initial phase.
Tools and Materials You Will Need
One of the best things about this project is that it requires very few supplies. You likely have most of these items in your home or gardening shed already.
- A small container of high-quality orchid cloning paste.
- A pair of fine-tipped tweezers or a sharp, sterile hobby knife.
- Cotton swabs or a clean toothpick for application.
- Isopropyl alcohol (70%) for sterilizing your tools.
- Latex or nitrile gloves to keep the hormones off your skin.
Sterilization is the most important step in this list. Orchids are susceptible to viruses and bacterial infections that can spread through open wounds on the stem.
Always wipe your tweezers or knife with alcohol before touching the plant. It only takes a second, but it can save your orchid’s life in the long run.
I also suggest working in a well-lit area. The nodes can be quite small, and you want to be precise when you are peeling back the protective bract.
A Step-by-Step Guide to Applying the Paste
Now that you are prepared, let’s get into the actual application. Don’t be nervous! As long as you are gentle, your orchid will be perfectly fine.
Step 1: Locate the Nodes
Examine the flower spike from the bottom up. You will see several small “scales” along the stem. These are the bracts covering the dormant nodes.
I usually recommend choosing the nodes closest to the base of the plant. These are typically thicker and have better access to the plant’s main nutrient supply.
Step 2: Remove the Bract
Use your sterilized tweezers to gently grab the edge of the papery bract. Very carefully peel it away to reveal the tiny green bud underneath.
Be extremely careful not to nick or scratch the green bud itself. If you damage the bud, it may not grow, or it may produce a deformed plantlet.
If the bract is stubborn, you can use a needle to lift the edge slightly. The goal is to expose the “eye” of the node so the paste can make direct contact.
Step 3: Apply the Hormone Treatment
Dip your toothpick or cotton swab into the orchid cloning paste. You only need a very small amount—about the size of a grain of rice.
Dab the paste directly onto the exposed green bud. You want to cover the bud completely but avoid glopping it all over the rest of the stem.
Less is often more in this situation. If you apply too much, the excess can trap moisture and cause the node to rot instead of grow.
Step 4: Label and Monitor
If you are working with multiple plants, it is a good idea to label the spike with the date of application. This helps you track how long the process takes.
Place the orchid back in its usual spot with bright, indirect light. Avoid placing it in direct hot sun, as this can “cook” the paste and the delicate node.
What to Expect: The Timeline of Growth
Patience is a virtue when it comes to orchids. You won’t see a new plant overnight, but the changes will begin happening deep within the stem immediately.
Within 2 to 3 weeks, you should notice the node beginning to swell. It will look like a tiny green mitten or a small triangular leaf pushing out from the stem.
If the growth is pointed and thin, it might actually be a secondary flower spike rather than a keiki. This is a common side effect of the hormones.
While a second round of flowers is beautiful, it isn’t a “clone.” If this happens, don’t worry! You can enjoy the blooms and try again on a different node later.
A true keiki will clearly show small leaves within a month or two. Once the leaves appear, the plantlet will begin the long process of developing its own roots.
Nurturing the Keiki: The “Rule of Three”
Once your keiki is growing, your job is to keep the mother plant happy enough to support two lives. This is where many beginners get a bit over-eager.
Do not try to remove the baby orchid too early. It is entirely dependent on the mother plant for water and nutrients until it develops its own root system.
Experienced growers follow the Rule of Three. You should only consider removing the keiki when it has at least:
- Three leaves that are healthy and firm.
- Three roots that are actively growing.
- Three inches of length on those roots.
If you remove it before it has sufficient roots, the baby will likely dehydrate and die before it can establish itself in its own pot.
I have seen many gardeners rush this step because they are excited. Trust me, leaving it on the mother plant for an extra month is the best insurance policy you can have.
Environmental Factors for Success
While the orchid cloning paste provides the chemical trigger, the environment provides the fuel. Temperature and humidity play massive roles in your success rate.
Orchids love warmth. If your home is consistently below 65°F (18°C), the metabolism of the plant slows down, and the keiki may stall in its growth.
Try to keep the plant in a room that stays between 70°F and 80°F. This “tropical” warmth encourages the rapid cell division required for cloning.
Humidity is also vital. Since the keiki’s new roots are exposed to the air, they can dry out quickly. Placing a humidity tray nearby can make a world of difference.
You can also lightly mist the keiki’s developing roots with water every morning. Just be careful not to let water sit in the “crown” (the center where the leaves meet).
Feeding Your Growing Family
Since the mother plant is doing double duty, she needs extra nutrition. During the cloning process, I recommend using a balanced orchid fertilizer.
Look for a “weakly, weekly” approach. Use a half-strength solution of fertilizer every time you water, rather than a full dose once a month.
Some growers prefer a high-nitrogen fertilizer (the first number in the N-P-K ratio) during keiki production. Nitrogen is the primary building block for green leaf growth.
However, don’t overdo it. Too much fertilizer can lead to salt buildup in the potting media, which can damage the mother plant’s sensitive roots.
Always flush the pot with clear, fresh water once a month to wash away any residual minerals. This keeps the root environment healthy for everyone involved.
Potting Your New Orchid Clone
The day has finally arrived! Your keiki has met the Rule of Three, and it is time for it to move into its own home. This is a delicate surgical procedure.
Use a sterilized blade to cut the flower spike about an inch above and an inch below the keiki. You are essentially “harvesting” the section of the stem the baby is attached to.
Do not try to pull the keiki off the stem. It is fused to the mother’s tissue, and pulling it will cause significant damage to the baby’s base.
Choose a very small pot for the new plant. Orchids like to feel “snug.” A 2-inch or 3-inch clear plastic pot is usually perfect for a first-year clone.
Use high-quality New Zealand sphagnum moss or a fine-grade bark mix. Gently tuck the roots into the media, making sure they are supported but not crushed.
Frequently Asked Questions About orchid cloning paste
Can I use the paste on any type of orchid?
While it is most effective on Phalaenopsis (Moth Orchids), many gardeners have had success with Dendrobiums and Oncidiums. However, the nodes on those species are located on the “canes” or “pseudobulbs” rather than a flower spike.
How many nodes should I treat at once?
I recommend treating no more than two nodes per plant. If you try to grow five keikis at once, the mother plant may become exhausted and drop its leaves. It is better to have one healthy clone than five weak ones.
What if the node turns black after application?
If the node turns black or mushy, it is likely a bacterial infection. This usually happens if the tools weren’t sterile or if too much paste was used. Cut the spike below the infected area and treat the cut with a dash of cinnamon (a natural antifungal).
Does the paste expire?
Most orchid cloning paste products have a shelf life of about two years if kept in a cool, dark place. If the paste becomes very hard or changes color significantly, the hormones may have degraded, and it is time for a new jar.
Will the keiki bloom right away?
Usually, no. A keiki needs to focus on leaf and root growth first. It typically takes 1 to 2 years of independent growth before a cloned orchid is mature enough to produce its first flower spike.
Conclusion: Your Journey to an Orchid Jungle
Growing your own orchids from clones is one of the most rewarding experiences a gardener can have. It turns a simple hobby into a fascinating experiment in plant biology.
By using orchid cloning paste correctly, you are giving your plants the opportunity to live on through their offspring. It is a sustainable and cost-effective way to expand your collection.
Remember to be patient, keep your tools clean, and always prioritize the health of the mother plant. With a little bit of time and some hormone help, you will soon have a windowsill full of beautiful, home-grown orchids.
Don’t be afraid to give it a try—your orchids are tougher than they look! Happy growing, and may your garden always be in bloom.
