Understanding Rooting Hormones and their Benefits

Before we dive into the application process, let’s take a closer look at rooting hormones and how they promote root growth in plant cuttings. Rooting hormones are synthetic or natural substances that stimulate root development in cuttings. They contain auxins, which are plant hormones that encourage cell division, elongation, and differentiation in plant cells. Using rooting hormone products can increase the success rate of propagating new plants and expedite the growth of new roots.

Rooting hormone products come in three forms: liquids, powders, and gels. Liquid hormones are the most common and are available in various concentrations. Powder rooting hormones are a dry concentrate form that requires dilution before use. Gel rooting hormones contain the hormone in a thick gel form that can be directly applied to the cutting. Each product type has its advantages depending on the plant species and cutting type you are working with.

The benefits of using root growth hormones for cuttings are numerous. These hormones increase the chances of successful propagation by enhancing the root development process. They also help plants establish themselves quickly, especially when transplanting. Rooting hormones also increase the resistance of plants to environmental stresses, such as drought, and improve the overall health of plants.

Selecting the Right Rooting Hormone for Your Plant Cuttings

Choosing the right rooting hormone product is essential for the successful propagation of plant cuttings. There are different types of rooting hormone products, including gels, powders, and liquids. When selecting a rooting hormone product, consider the type of cutting, the plant species, and the desired outcome.

For softwood cuttings, it is recommended to use a rooting hormone powder, whereas gel rooting hormones are suitable for hardwood cuttings. Liquid rooting hormone products are versatile and can be used for different types of cuttings.

When it comes to plant species, some plants are more responsive to rooting hormones than others. For example, plants that are easy to propagate, such as spider plants and pothos, may not require rooting hormones. However, plants that are difficult to propagate, such as roses and azaleas, benefit greatly from the application of rooting hormones.

Consider the desired outcome when selecting a rooting hormone product. If you want to expedite the rooting process and promote fast growth, choose a product with a high concentration of rooting hormones. Alternatively, if you want to reduce the risk of damaging the cuttings, consider a product with a lower hormone concentration.

Preparing Your Plant Cuttings for Rooting Hormone Application

Before applying rooting hormones to your plant cuttings, it is crucial to properly prepare them to increase the chance of successful root development. Follow these gardening tips for optimal results:

Select Healthy Stems

Choose healthy stems from the parent plant that are free from diseases, pests, or damages. Avoid selecting stems that are too young or too old, as they may not root effectively.

Make Clean Cuts

Use a sharp, sterilized knife or pruning shears to make a clean cut at a 45-degree angle. This angle increases the surface area of the cutting, making it easier for the hormone to penetrate and stimulate root growth.

Remove Excess Foliage

Remove any excess foliage from the stem, leaving only a few leaves at the top. This will reduce the moisture loss from the cutting through transpiration, allowing it to focus on root development.

Explore Different Plant Propagation Techniques

Depending on the plant species and the desired outcome, there are different plant propagation techniques you can use to further enhance the success rate of your cuttings. Some examples include air layering, division, and grafting. Research and determine the best propagation technique for your plant.

How to Use Rooting Hormones For Plant Cuttings: Understanding the Application Methods

Rooting hormone application is an essential process that can significantly increase the success rate of plant propagation. However, the effectiveness of the rooting hormone largely depends on the application method used. There are various methods for applying rooting hormones to plant cuttings, each with its own advantages and disadvantages.


The most popular method of applying rooting hormone to plant cuttings is dipping. In this method, the cut ends of the plant cuttings are dipped directly into the rooting hormone solution. Dipping is effective for both powder and liquid hormone products, and it provides an even distribution of the hormone on the cutting. The disadvantage of dipping is that it can contaminate the rooting hormone solution with bacteria, fungus, or disease, which can further affect the success of the rooting process.


Rolling is another common rooting hormone application method. This technique involves rolling the cut end of the plant cutting in rooting hormone powder. Rolling is an effective method for powder rooting hormone products, and it allows for better control of the amount of hormone applied to the cutting. However, it can be difficult to achieve an even distribution of the powder hormone on the cutting, and it can leave an excess amount of hormone that can harm the plant cutting.


Spraying is a less common rooting hormone application method, but it can be effective for liquid rooting hormone products. In this method, the rooting hormone solution is sprayed directly onto the leaves and stems of the plant cutting. Spraying can provide an even distribution of the hormone, and it minimizes the risk of contamination of the hormone solution. However, it can be difficult to control the amount of hormone applied to the plant cutting, and it can evaporate quickly if not monitored properly.

Bottom Soaking

Bottom soaking is a rooting hormone application method that involves placing the cut end of the plant cutting in the rooting hormone solution for an extended period. This method allows for maximum hormone absorption, and it can be effective for both powder and liquid hormone products. The disadvantage of bottom soaking is that it can increase the risk of contamination of the hormone solution, and it can cause harm to the plant cutting if left for too long.

Air Layering

Air layering is a plant propagation technique that also involves the application of rooting hormone. In this method, a cut is made on the stem of the parent plant, and rooting hormone is applied to the cut. The cut section is then wrapped in moist sphagnum moss, and the area is covered with plastic wrap to retain moisture. This technique can be effective for propagation of plants that are difficult to propagate from cuttings. However, it can be a time-consuming process, and it requires precise cutting and hormone application.

When selecting a rooting hormone application method, consider the type of rooting hormone product you are using and the type of cutting you are propagating. Take into account the advantages and disadvantages of each method and select the most suitable one for your plant cuttings.

Step-by-Step Guide to Applying Rooting Hormones

Now that you have selected the appropriate rooting hormone product and prepared your plant cuttings, it’s time to apply the rooting hormone accurately. Follow these simple steps for successful rooting:

  • Prepare the rooting hormone solution: Mix the rooting hormone powder or liquid with water as per the instructions on the product label. Use a clean and sterile container to avoid any contamination.
  • Treat the cuttings: Dip the cut end of the plant cutting into the rooting hormone solution. Ensure that the entire cut end of the cutting is covered in the solution. Alternatively, you can use a brush to apply the hormone solution to the cut end of the cutting if the stem is too thick to be dipped.
  • Avoid excess hormone: Shake off any excess hormone solution from the cutting to avoid over-saturation and wastage. It’s important to use only the required amount of hormone as excessive use can have adverse effects on the rooting process.
  • Plant the cuttings: After applying the rooting hormone, plant the cuttings into a moist rooting medium, such as potting soil or vermiculite. Make sure the medium is well-draining and the cuttings are planted deep enough to provide stability.
  • Provide optimal conditions: After planting, place the cuttings in a warm and brightly lit area with high humidity. Cover the cuttings with a plastic bag or dome to maintain the moisture level. Monitor the rooting progress and do not overwater or underwater the cuttings.

By following this step-by-step guide, you can apply rooting hormones accurately and increase the chances of successful root development for your plant cuttings.

Providing Optimal Conditions for Rooting

Once you have applied rooting hormones to your plant cuttings, it is crucial to provide optimal conditions for root development. By creating a favorable environment, you can increase the success rate of plant propagation and promote healthy root growth.


Rooting typically occurs in warm temperatures, between 65°F and 75°F. If the temperature is too low, root development may be slow or not occur at all. On the other hand, if the temperature is too high, the cuttings may wilt or become dehydrated. To maintain an optimal temperature, you can use a thermometer to monitor the temperature and adjust the environment accordingly.


High humidity is essential for successful rooting. It helps prevent dehydration of the cuttings and encourages the development of new roots. To maintain a high level of humidity, you can cover the cuttings with a plastic bag or dome, creating a mini greenhouse. Mist the cuttings regularly to keep the environment moist.


While some plant cuttings do not require light for rooting, others do. If your cuttings need light, place them in a location where they can receive bright, indirect light. Avoid placing them in direct sunlight, as this can cause the cuttings to dry out or become overheated. If you are propagating in low light conditions, consider using artificial grow lights to supplement natural light.


Good air circulation is important for preventing mold and encouraging healthy root growth. To provide adequate airflow, avoid overcrowding the cuttings and ensure there is enough space between them. You can also use a small fan to circulate the air and reduce the risk of mold or fungus growth.


When rooting cuttings, it is important to keep the soil moist but not waterlogged. Overwatering can lead to root rot or fungal growth, while underwatering can cause the cuttings to dry out and wilt. To water your cuttings, use a spray bottle or watering can to gently water the soil around the stem. Be careful not to water the leaves, as this can lead to fungal growth.

Plant Propagation Techniques

There are several plant propagation techniques that can further improve the success rate of rooting your plant cuttings. One of the most effective techniques is bottom heat. By placing your plant cuttings on a heat mat, you can raise the temperature and encourage root growth. Another technique is misting, which involves spraying the cuttings with water regularly to maintain high humidity. Finally, you can use rooting hormone gel or powder to provide a continuous supply of rooting hormone to the cuttings, promoting healthy root development.

By providing optimal conditions for rooting, you can increase the success rate of propagating new plants and ensure healthy root growth. Remember to maintain warm temperatures, high humidity, bright but indirect light, good air circulation, and proper watering techniques. Additionally, consider using plant propagation techniques such as bottom heat, misting, and rooting hormone products to support successful root development.
