Did You Know?
1. The best time of year to take hydrangea cuttings is in early summer, specifically during the months of June and July. This is when the plants are at their most active growth stage, making it easier for the cuttings to establish roots.
2. Hydrangeas have the ability to change colors based on the soil pH. If the soil is acidic (pH below 7), the flowers will be blue or purple. However, if the soil is more alkaline (pH above 7), the flowers will appear pink or even red. This fascinating phenomena is due to the specific pigment in the flowers that reacts with the soil chemistry.
3. Hydrangea cuttings can be propagated using a variety of methods, including tip cuttings, softwood cuttings, and hardwood cuttings. Each method has its own set of requirements, but all can be successful with proper care and attention.
4. While most hydrangea varieties can be propagated through cuttings, it’s worth noting that some cultivars or hybrids may have patented genetics, meaning you might need permission from the breeder or a licensing agreement in order to propagate them. Always check the variety specifics to ensure you are legally able to take cuttings.
5. Hydrangeas are actually native to Asia, specifically China, Japan, and Korea. They have a rich history in these countries and are highly revered as ornamental plants. In fact, the hydrangea flower holds different cultural meanings in each country, symbolizing anything from heartfelt emotions to gratitude and apology.
Best Time Of Year: Late Summer For Hydrangea Cuttings
Late summer, specifically the months of July and August, is the optimal time for taking hydrangea cuttings. During this period, hydrangea plants are more mature and have developed healthy stems suitable for propagation. However, it is important to note that the timing may slightly vary depending on the specific variety of hydrangea.
Late summer is the period when the plant’s growth has tapered off, but before the arrival of autumn. Taking hydrangea cuttings during this time offers several benefits:
- The plant is not actively growing, which increases the success rate of propagating healthy new plants.
- Taking cuttings at this time allows the plants to develop roots and establish themselves before the harsh conditions of winter.
- This timing aligns perfectly with the natural growth cycle of hydrangeas, increasing the chances of successful propagation.
Remember, late summer is the ideal time to take hydrangea cuttings, providing the best conditions for successful propagation.
Propagation Method: Woody Base, Soft Tip
When taking hydrangea cuttings, select suitable plant material to ensure successful propagation. The ideal cutting should have a woody base and a soft tip. The woody base provides stability and prevents rotting, while the soft tip contains root development potential.
To collect the material for cuttings, use sharp secateurs to carefully remove a healthy stem from the desired hydrangea plant. It is important to choose a stem that is neither too young nor too old. A cutting with a woody base is crucial to prevent rot and increase the chances of successful propagation. Once the stem is collected, use a clean knife to trim the cutting, removing any excess leaves or side shoots.
- Select suitable plant material (woody base + soft tip)
- Use sharp secateurs
- Choose a stem that is neither too young nor too old
- Remove excess leaves or side shoots.
Propagation Medium: Gritty Compost, Not Water
Hydrangea cuttings require a gritty compost medium for propagation, as they do not readily root in water. To encourage root development, it is important to use a suitable propagation medium.
Here are the steps to prepare and propagate hydrangea cuttings:
-
Prepare a propagation tray filled with a well-draining and gritty compost mix. Make sure the compost mix allows for proper moisture retention while preventing excessive water accumulation that could lead to rotting.
-
Insert the prepared hydrangea cuttings into the compost. Ensure that the woody base of each cutting is firmly inserted into the medium.
-
Avoid overcrowding the cuttings to allow sufficient airflow around each individual cutting.
By following these steps, you can effectively propagate hydrangea cuttings in a compost medium.
- Use a gritty compost mix for hydrangea cuttings
- Ensure the woody base of each cutting is firmly inserted into the medium
- Avoid overcrowding to allow sufficient airflow
“Water propagation is ineffective for hydrangeas, as they do not readily root in water.”
Developing Roots: Six Weeks In A Propagator
Once the hydrangea cuttings are inserted into the gritty compost medium, it is essential to provide them with the optimal conditions for root development. To retain moisture and create a controlled environment, it is recommended to keep the cuttings in a propagator or greenhouse.
A propagator provides the necessary warmth and humidity required for successful root development. Keep the cuttings in the propagator for approximately six weeks, ensuring that the compost remains moist but not waterlogged. During this time, regularly monitor the cuttings for signs of root development, such as new growth or resistance when gently tugged.
Overwintering: Cold Frame For Hydrangea Cuttings
After the six-week period in the propagator, it is important to prepare the hydrangea cuttings for overwintering. Overwintering refers to the process of protecting the newly propagated plants during the colder months to ensure their survival.
Transfer the rooted hydrangea cuttings to a cold frame or a similar protective structure. This provides a shield from harsh winter weather, including frost and excessive moisture. Ensure that the cuttings are adequately spaced to prevent overcrowding, as this can lead to disease and poor growth. During the winter months, regularly monitor the cuttings for any signs of stress or disease, and provide appropriate care as necessary.
In spring, as the weather begins to warm up and the risk of frost diminishes, the overwintered hydrangea cuttings can be potted on. Transferring them to individual pots allows for further growth and development while providing adequate space for root expansion. Carefully transplant each cutting into a well-draining potting mix, ensuring the roots are properly covered and supported.
By following these guidelines, late summer becomes the ideal time for taking hydrangea cuttings. This method of propagation allows for the enjoyment of beautiful hydrangeas at no cost while also providing an opportunity to expand your garden and share these stunning plants with others.

Frequently Asked Questions
What month do you take hydrangea cuttings?
To ensure successful propagation, it is recommended to take hydrangea cuttings during late spring or early summer. This period typically falls between May and mid-July when new stems begin to harden. During this time, the new hydrangea stems exhibit a slight flexibility, making it easier to snap off cuttings that possess a high potential for robust growth.
Can I propagate hydrangeas in winter?
Yes, hydrangeas can be propagated during winter. The ideal time for making cuttings is from the one or two year old wood. To propagate, simply cut the stem just beneath and above a node, with the cutting being approximately 20cm long. Nodes are identifiable as the slight swellings or bumps along the stem where the leaves emerge from. Winter is an opportune time to create new hydrangea plants for future growth and enjoyment.
What is the best way to root a hydrangea cutting?
The most effective way to root a hydrangea cutting is by planting it in a cutting-friendly, well-draining mix designed for seed starting. Unlike many other plants, hydrangeas do not root well in water. Therefore, it is crucial to use a mixture that includes coir, sand, or peat moss. When planting the cutting, ensure it is placed into the soil, right up to the edge of the bottom set of leaves. This method provides the optimal conditions for successful rooting and subsequent growth of the hydrangea plant.
What temperature do hydrangea cuttings need?
To ensure successful growth and root formation, hydrangea cuttings require an optimal temperature range between 60 and 80 degrees Fahrenheit. This temperature sweet spot, ideally in a sheltered setting away from direct sunlight and wind, provides a conducive environment for the cuttings to establish new growth. By following these guidelines, you can expect to see signs of new growth within two weeks and fully developed roots ready for transplantation by the end of the fourth week.
