Cloning plants with rooting hormone

Chances are you saw people propagated plants to create new clones before. They often dip/cover the cutting with a stimulant in the gel form.

That gel stimulant is the rooting hormone. It is used to accelerate the rooting rate.

But how well do you know about plant rooting hormone? Why do growers use the rooting hormone for propagation, how can it increase the success rate, and what are the best rooting hormones on the market?

I’m going to tell all about them in this post.

What is rooting hormone and why using it?

Naturally, plants can manufacture their own rooting hormone after some time. That explains why some plants are easy to clone.
However, some do not produce enough the hormones during the cloning process, and the others even cannot root without using a stimulating rooting hormone.

As a result, rooting hormones (in the synthetic or organic form) are used commonly by gardeners when propagating.

Rather than letting the new cuttings struggle on their own, rooting hormones encourage faster and stronger root development.
It also protects the cuttings from disease and fungus during the cutting step.

There are some types of rooting hormones. Each comes with its pros and cons.

Different types of rooting hormones


Liquid rooting hormones come in two forms: ready-to-use and concentrated.

Anything, which can be used immediately, is convenient. With a ready-to-use form, growers don’t have to think and care about how to custom the liquid as the manufacturers have done that job for you.

But other growers want to mix their hormones to bring in in the concentration rate they want for the cuttings. As not all plants are the same, they do not wish to the same concentration level for all of them.

One caution when working with the liquid form is: don’t dip the cutting directly in the bottle containing the liquid rooting hormone. Instead, pour the liquid hormone into a separate container, and place your cutting here. This is so that you will not contaminate the whole bottle for the next use.


Powder form is known for its long shelf-life, and it does not need refrigeration.

To make the powder easy to adhere to the cuttings, you can dip the stem in water before applying. To prevent contamination and diseases for the powder bottle, again you should take some small batches of powder and pour into a small container, bowl.

Powder seems to be less efficient than the liquid form as the cutting texture can take up more hormones in the water form. However, it does win over with its longer shelf-life, sanitation, which makes this type cost-effective. That’s why powder is used widely by commercial growers.


Gel rooting hormone is really convenient. That’s why it’s the most common rooting hormone type used by indoor gardeners.

Even though gel cannot compare with powder and concentrated liquid form regarding the versatile ability, it offers higher convenience and thicker coverage on the cutting. Better adherence to the cutting ensures the plant tissue can take in more hormone.

No doubt, gel form will continue the most preferred rooting hormone when cloning by indoor gardeners and hobbyists.

And like other forms, don’t place the cutting directly in the gel bottle in case it can cause contamination and spread diseases, take. Take a small amount from the container and place in a separate cup or bowl.

Organic alternatives

If you are environmentally aware and prefer organic form, you can go with honey and willow extracts. Many growers had great success with them, but the results most of the time are not as good as the synthetic forms above.


Surprising to know that honey is a natural rooting hormone. But it’s true. Many growers have found a fair success rate using honey to clone root cutting. This is because honey is a natural antiseptic and has an anti-fungal trait. These qualities are beneficial in protecting the young cutting from bacteria to focus on rooting.
That’s the primary role of honey. Naturally, it does not contain the rooting hormone for plants, only to protect them from diseases and infections. That’s why compared to other synthetic rooting hormones, it is slower to see the results with honey.

Willow Extract

Probably the best organic rooting hormone available. This is because willow extract contains two auxin hormones: salicylic acid (SA) and indolebutyric acid (IBA), which are found in high concentration in the willow trees’ growing tips.
These two auxins in combination encourage root growth while protecting the cutting from diseases and bacteria.

How to use the rooting hormones for the best results.

Right Environment

Make sure that your place has a proper growing condition for the propagation – warm temperature (20 – 24oC), moist daily, weak daylight. Otherwise, even if with the help of the best rooting hormones, the rooting will never happen.

Make a good cutting first.
The rooting hormones only work best with a fresh and clean cut. Make sure that you use a sterilized knife for the cutting. And you must make a 45-degree cut to increase the surface of the cutting.

Don’t infect the whole rooting hormone bottle
It’s advised that you should take some amounts of rooting hormones and pour in into a separate pot, bowl, or cup. This saves the remained rooting hormones in the bottle from the risk of contamination.

Cover the cutting’s end
You only need to dip the clone’s end into the rooting hormone, about 1 inch in depth. You don’t cover the whole cutting with the rooting stimulant.

Use proper concentration.
Normally, woody plants need a higher concentration of rooting stimulants while herbaceous plants require lower concentration. Keep that in mind not to add more than enough or underdose the amount and concentrations of the rooting hormones.
