Temperature:

Plumeria cuttings typically callus best in warm temperatures ranging from 70°F to 90°F (21°C to 32°C). Warmer temperatures promote faster callus formation. Avoid temperatures below 50°F (10°C) as they can slow down or inhibit callusing.

Humidity:

Moderate humidity levels are beneficial for callus formation. Too much humidity can lead to rotting, while low humidity can cause the cutting to dry out before callusing occurs. Aim for relative humidity levels between 50% to 70%.

Air Circulation:

Adequate air circulation around the cuttings helps prevent fungal diseases and promotes healthy callusing. However, avoid placing cuttings in direct drafts, which can cause them to dry out too quickly.

Cutting Size and Type:

Larger Plumeria cuttings generally tend to form calluses more easily than smaller ones due to their higher energy reserves. Moreover, greenwood cuttings (taken from young, actively growing stems) usually develop calluses faster than hardwood cuttings (taken from older, dormant stems). However, greenwood cuttings require more attention and care as they tend to dry out faster.

Cutting Preparation:

To improve the formation of calluses in plumeria cuttings, it is important to prepare the cut end properly. This can be done by using a sharp and sterilized knife to make a clean cut. The cut end should be allowed to dry for a week or two until a callus forms before planting. It is believed that making diagonal cuts can expose more surface area, leading to better callusing, but most growers use a 90-degree cut.

Callus Inducing Hormones:

Some gardeners use rooting hormone powders or gels that contain auxins, such as indole-3-butyric acid (IBA), to promote callus formation and root development. Although not essential, these products can speed up the process. Hormones work best if applied to the cutting immediately after taking it. The longer you wait, the less effective it becomes.

Substrate:

After a callus has formed on the cutting, it should be placed in a well-draining substrate like a mix of perlite and potting soil or coarse sand. This will help to maintain optimal moisture levels around the cut end while allowing excess water to drain away. Excess moisture around the cutting can hinder callusing and promote rot. When placing the cutting in the substrate, water it once and then avoid watering it again until 3 or 4 mature leaves have formed. If the cutting becomes withered, mist it until it looks normal again.

Avoiding Direct Sunlight:

Placing cuttings in direct sunlight can cause them to dry out too quickly and may inhibit callus formation. Instead, provide bright, indirect light or dappled shade until calluses have formed and roots begin to develop.

Conclusion:

The success of propagating plumeria cuttings is significantly influenced by the growing conditions you maintain. By closely monitoring and adjusting these environmental factors, you create an ideal setting that fosters the callusing process, which is critical for the subsequent development of healthy roots and robust plant growth.

By paying meticulous attention to these factors and providing the optimal conditions, you significantly enhance the likelihood of success in your plumeria propagation endeavors. The goal is to create a stable, nurturing environment where your plumeria cuttings can flourish, ultimately leading to the development of strong, healthy plants.

Introduction

Using rooting hormone can significantly enhance the success rate of propagating Plumeria cuttings. The timing of its application plays a critical role in the rooting process. This guide provides insights into when and how to apply rooting hormone effectively to Plumeria cuttings.

When to Apply Rooting Hormone

After Cutting and Curing

1. Post Cutting: After taking your Plumeria cutting, optionally apply the rooting hormone. Rooting hormones are most effective when applied immediately after the cutting has been taken.
2. Allow to Callus: first, let it dry and callus. This curing process typically takes about 1-2 weeks, depending on the climate and humidity.
3. Before Planting: Apply the rooting hormone to the cut end of the Plumeria cutting just before you plant it in the soil. The callused end should be dry and healed to provide the best conditions for the hormone to work.

Best Practices for Applying Rooting Hormone

Choosing the Right Formulation

1. Type of Hormone: Rooting hormones are available in various forms, such as powders, gels, and liquids. Each type has its own method of application.
2. Concentration: Ensure the concentration of the hormone is suitable for Plumeria cuttings. A very high concentration can sometimes be counterproductive.

Application Techniques

1. Powder Hormone: Dip the callused end of the cutting into rooting hormone. After a firm callus has formed, dip the cutting in water then into the rooting hormone powder. Tap off any excess powder.
2. Liquid Hormone: If using a liquid formulation, dip the end directly into the hormone solution for a few seconds.
3. Gel Hormone: Apply the gel to the cutting end with a clean brush or dip the end directly into the gel.

Planting the Cutting

1. Immediate Planting: After the plumeria cutting has callused and applying the rooting hormone, plant the cutting in a well-draining soil mix immediately. This ensures the hormone stays in contact with the cutting and doesn’t dry out or rub off.

Post-Application Care

1. Watering: Water the soil lightly to settle it around the cutting. Avoid overwatering, which can wash away the hormone.
2. Environment: Place the cutting in a warm, bright area but out of direct sunlight, which can hinder the rooting process.

Conclusion

Applying rooting hormone to Plumeria cuttings just before planting them, after they have cured, can significantly increase the chances of successful rooting. By following the appropriate application techniques and providing the right aftercare, your Plumeria cuttings are more likely to develop robust roots, leading to healthy and thriving plants.

Please keep in mind to adjust your techniques according to the environment and conditions of your growing space. Cooler areas may require more time for the cuttings to callus and root properly. Additionally, you may choose to wrap the cutting in Saran Wrap, but this is optional.

Materials You’ll Need:

1. Healthy, mature plumeria plant with disease-free branches
2. Sharp, sterilized pruning shears or a pruning saw
3. Rooting hormone (optional but recommended)
4. A clean, dry container or tray
5. Well-draining rooting medium (perlite, potting soil (without additives), or a mixture of perlite and peat moss or choir)
6. A Spray bottle with water.
7. Clear plastic bag or humidity dome (optional)
8. Warm and bright location (without direct sunlight)

Step-by-Step Guide:

1. Selecting the Right Cutting: When taking cuttings from a plumeria plant, it’s important to select a mature plant that is at least 1-2 years old and has healthy, disease-free branches. The ideal time to take these cuttings is during the spring or early summer when the plant is in its active growth phase.
2. Preparation: To prevent the spread of diseases, it’s important to ensure that your pruning shears or saw are clean and sterilized before taking cuttings. You can achieve this by sterilizing them with rubbing alcohol or a mixture of 1 part bleach to 9 parts water.
3. Identify the Cuttings: When searching for branches, aim for those that measure 12 to 18 inches in length and possess a minimum of two to three growth nodes, which are the areas where leaves or branches sprout.
4. Cut the Stem: To propagate a plant, use sharp pruning shears or a saw to make a clean cut just below a leaf node at a 45-degree angle. This angle helps maximize the surface area for rooting. Some people believe cutting at a 90-degree angle will produce more roots, but you can experiment with both methods to make your own decision. If the cutting is large, you can divide it into smaller sections, making sure each section has at least one growth node.
5. Apply Rooting Hormone (Optional): If you want the best possible outcome, it is advised to use rooting hormone right after taking the cutting. Waiting too long can decrease its effectiveness. To speed up and increase the chances of successful rooting, dip the callused end of the plumeria cutting into rooting hormone powder and shake off any excess to avoid overdoing it.
6. Remove Leaves: To prevent water loss through transpiration, it’s recommended to remove the majority of leaves from the cutting, leaving around 1/2 inch (1.3 cm) of the leaf stem attached to the stem. By doing this, the cutting can still undergo photosynthesis while minimizing water loss.
7. Callusing Time: Once you have cut the plumeria, it’s important to keep the cuttings in a warm and dry location for around 1 to 2 weeks. This will allow the cut ends to callus properly. It’s important to make sure that the callus is hard and not soft before planting. This process of callusing helps prevent rotting when the cutting is placed in the rooting medium.
8. Prepare the Rooting Medium: To propagate a plant, prepare a clean container or tray with a well-draining rooting medium. This can be a mix of potting soil, coarse perlite, or a combination of perlite and peat moss or choir. Make sure the medium is moist but not overly saturated with water. A recommended ratio is 1/2 coarse perlite.
9. Plant the Cutting: To plant a plumeria cutting, create a hole in the rooting medium and insert the callused end. Make sure to bury at least one growth node and plant the cutting about 2″-3″ deep, depending on its size. Then, gently firm the medium around the cutting to secure it in place.
10. Provide Humidity (Optional): To create a more humid environment for your plant cuttings, you have the option to place the container inside a clear plastic bag or use a humidity dome. This helps to retain moisture and promote healthy rooting.
11. Place in a Warm and Bright Location: For best growth results, put the container in a warm, well-lit area that receives indirect sunlight. Avoid placing it in direct sunlight, as this can harm the cutting. To promote rooting, aim for a soil temperature between 75-95°F.
12. Mist the Cutting: To ensure the health of your cutting, it’s important to mist it regularly. If you’re using a humidity dome, be sure to spray the inside of the plastic bag or dome to maintain a moist environment. However, be careful not to overwater your cutting, as too much moisture can cause it to rot.
13. Rooting Time: The amount of time it takes for a plumeria cutting to root can vary depending on the type of plumeria and the environmental conditions. It may take anywhere from a few weeks to a couple of months. Signs that the cutting has rooted include the emergence of new growth or resistance when gently tugging on the cutting.
14. Transplanting: Once the cutting has developed a robust root system, typically with several inches of fresh growth, it is ready to be relocated to a well-draining potting mix that is suitable for plumerias.

If you follow these steps, you can take plumeria cuttings like a professional nurseryman and successfully propagate new plants. This is an exciting and rewarding process that enables you to grow more beautiful plumeria specimens to share with others and enjoy.
