Rooting hardwood cuttings is a popular technique used by gardeners and nursery professionals to propagate a wide range of beautiful plants. This method involves removing a cutting from the parent plant and encouraging it to develop roots, which allows the cutting to grow into its own individual plant. One of the most effective methods for rooting hardwood cuttings is the long soak method.
The long soak method requires a few simple steps. First, choose a healthy, disease-free hardwood cutting from your favorite tree or plant. Remove any leaves or buds from the cutting, leaving only a few at the top. Then, dip the bottom of the cutting into a rooting hormone powder. This hormone helps stimulate root growth and increases the chances of successful rooting.
Next, fill a container with a well-draining propagation media, such as a mixture of sand and peat moss. Make a hole in the media using a pencil or your finger, and insert the cutting so that about one-third of its length is buried in the media. Firmly press the media around the cutting to ensure good contact.
Once all the cuttings are planted, water them thoroughly to settle the media and ensure good moisture penetration. Then, place the container in a sheltered location, such as a cold frame or a sink in your garden. Leave the container there for a couple of years, allowing the cuttings to develop strong roots and mature into healthy plants.
The long soak method works well for many types of plants, but it is especially effective for plants that are difficult to root using other propagation methods. It can also be used for plants that are easy to root, such as some deciduous trees and shrubs, to speed up the rooting process.
One of the unique advantages of the long soak method is that it does not require the use of a misting system or a greenhouse. This makes it a convenient and cost-effective method for gardeners who do not have access to specialized equipment. Additionally, the long soak method allows the plants to develop strong root systems from the start, which can lead to faster growth and better establishment when the plants are planted in their permanent location.
In conclusion, rooting hardwood cuttings using the long soak method is a simple and effective way to propagate a wide range of plants. With a few basic steps and some patience, you can grow new plants from your favorite trees and shrubs. So why not give it a try and see what unique and beautiful plants you can propagate from your garden?

3 Easy Hardwood Cutting Methods
When it comes to propagating plants, using hardwood cuttings can be an effective and easy method. There are several ways to root hardwood cuttings, but here are three popular and easy methods that you can try:
- The Long Soak Method: This method involves soaking the hardwood cuttings in water for an extended period of time, usually several weeks. The cuttings are then planted directly into well-draining soil or a rooting medium. This method works well for plants that have a reputation for being difficult to root.
- The Rhizopon Method: Rhizopon is a rooting hormone that can be used to stimulate root growth in hardwood cuttings. To use this method, you will need to make a solution of Rhizopon according to the instructions on the label. Dip the cuttings into the solution, ensuring that the base of each cutting is adequately covered. Then, plant the cuttings in a well-draining soil mix or rooting medium.
- The Trench Method: This method involves creating a trench in the ground and layering the hardwood cuttings horizontally in the trench. The cuttings should be placed about one-third of their length into the soil, leaving two-thirds exposed above ground. This method works well for climbers and certain shrubs, such as willow or ninebark. The cuttings should be watered sufficiently and kept in a cold frame or covered with a plastic sheet to protect them from frost until they have rooted.
Each of these methods has its own unique steps and requirements, so be sure to follow a proper guide when using them. Regardless of which method you choose, it’s important to take cuttings from healthy branches and ensure that they are sufficiently mature to promote successful rooting. With a little bit of patience and care, you’ll be well on your way to propagating new plants from hardwood cuttings.
Create more of your favorite trees and shrubs with these unique methods
If you have a favorite tree or shrub that you’d like to replicate, there are several unique methods you can try. One method that has been found to be particularly successful is rooting hardwood cuttings using the long soak method. This method involves taking cuttings from the desired tree or shrub during its dormant season and treating them with a solution to encourage root growth.
The first step in this method is to take cuttings from the tree or shrub you want to propagate. These cuttings should be about 10cm long and have at least three budsnodes. Once you have your cuttings, it’s important to remove any buds or leaves that would be submerged in the rooting media, as they can rot and hinder root development. You can do this by making a clean cut just above the bud or leaf.
Next, you will need to prepare a rooting media. A mix of equal parts peat moss and perlite is commonly used, but a mixture of half perlite and half sand also works well. You should moisten the rooting media before using it to ensure that it holds moisture and promotes root growth.
To prepare the cuttings for rooting, dip the base of each cutting in a rooting hormone powder. This hormone powder helps to stimulate root growth and increase the chances of success. After dipping the cuttings, insert them into the prepared rooting media. Make sure to push the cuttings into the media deep enough so that only one-third of the cutting is above the surface.
Once the cuttings are planted, you can cover them with a plastic bag or a plastic dome to create a mini greenhouse environment. This will help to retain moisture and promote root development. Place the cuttings in a location where they will receive bright, indirect light but will be protected from direct sunlight.
After planting, it’s important to keep the rooting media moist but not waterlogged. You can water the cuttings regularly by misting them with a spray bottle or by watering them from below. Be sure to check the moisture level of the media frequently to ensure it stays damp but not soggy.
It’s also important to protect the cuttings from extreme temperatures, wind, and wildlife. You can do this by placing them in a sheltered area, such as a greenhouse or a protected corner of your property. If the cuttings are exposed to cold temperatures, they may not root properly and could be lost.
After about six to nine weeks, you should start to see roots forming on the cuttings. At this point, you can carefully remove the cuttings from the rooting media and transplant them into individual pots or directly into the ground. If transplanting into the ground, make sure to space the rooted cuttings at least 40cm apart to allow for proper growth.
It’s important to note that not all trees and shrubs can be successfully propagated using this method. Evergreens, for example, are typically more difficult to root than deciduous trees and shrubs. However, many popular trees and shrubs, such as roses, mock oranges, and ninebark have been found to root well using this method.
If you’re looking to create more of your favorite trees and shrubs, rooting hardwood cuttings using the long soak method can be a unique and effective option. It’s a cost-effective way to grow new plants, and it allows you to create exact replicas of the trees and shrubs you love.
The Prep Work: Cut, Coat, then Make the Mix
Before you can start rooting hardwood cuttings using the long soak method, there are a few important steps to take. This section of the guide will walk you through the prep work necessary for successful propagation.
1. Cut: Begin by selecting healthy, young hardwood stems from deciduous trees or shrubs. These stems should be about 10cm long and have at least four pairs of leaves. Make a clean, diagonal cut just below a leaf node using a sharp and sterile pair of pruning shears or a knife.
2. Coat: To increase the chances of successful rooting, it’s important to apply a rooting hormone powder or gel to the base of each cutting. This helps stimulate root growth and provides protection against diseases. You can use commercially available rooting hormone tablets or make your own solution using a powdered rooting hormone. Dip the base of each cutting into the hormone solution and shake off any excess.
3. Make the Mix: The next step is to prepare the rooting medium where your hardwood cuttings will be planted. A mixture of sand, peat moss, and perlite or vermiculite is commonly used. A good ratio is one-third sand, one-third peat moss, and one-third perlite or vermiculite. Mix these ingredients thoroughly and ensure the mixture is moist but not too wet. Too much moisture can lead to rotting of the cuttings.
Remember, the prep work is crucial for successful rooting of hardwood cuttings. By properly selecting and preparing the cuttings, you can increase the chances of successful propagation. Now that you have completed the prep work, you can move on to the next step: planting the hardwood cuttings.
Method 1 – Roll them up in plastic to make the most plants
To propagate hardwood cuttings more effectively, one method that growers can use is rolling them up in plastic. This technique helps create a better environment for root development and increases the chances of successful propagation.
Propagation can become easier when done using the long soak method. Rather than transplanting the cuttings immediately into the soil, they are soaked for a period of time in a container filled with water. This step allows the cuttings to absorb plenty of moisture, giving them the assistance they need to form roots.
Danielle, a skilled propagator, suggests that a good mixture for the container is a combination of sand and perlite. This blend provides a well-draining medium that allows the cuttings to remain moist without becoming waterlogged.
Once the cuttings have been soaked for a specific period of time, typically between two to three weeks, they are ready to be rolled up in plastic. To do this, you can arrange the cuttings in a neat bundle and wrap them tightly with plastic wrap or place them in a plastic bag and seal it. This method helps create a warm and humid environment, which stimulates root growth.
It is important to note that this method works best for certain plant species that readily propagate from hardwood cuttings. Some examples of easy-to-root plants include shrubs like ninebark and ornamental fruiting trees.
After rolling up the cuttings in plastic, they can be stored in a warm and sheltered area, such as a greenhouse or a windowsill. This provides an ideal environment for the development of roots. The plastic wrap helps retain moisture and creates a greenhouse effect, ensuring that the cuttings receive the necessary warmth and humidity for successful rooting.
After a couple of weeks, the cuttings can be unwrapped from the plastic and checked for root development. If the cuttings have formed healthy roots, they can be potted up or transferred directly into the soil. If not, they can be placed back into the plastic and given more time to develop roots.
This method of rolling up the cuttings in plastic allows growers to propagate a larger number of plants from a single parent plant, making it a more efficient and cost-effective method of propagation.
Overall, the long soak method with the additional step of rolling up the cuttings in plastic offers a simple and effective way to root hardwood cuttings, especially for species that are easy to propagate. With proper care and attention, growers can enjoy a higher success rate in propagating their own plants.
