Did You Know?
1. The hydrangea flower’s name is derived from the Greek words “hydor” meaning water, and “angos” meaning vessel, referring to the shape of its seed capsules, which resemble ancient water vessels.
2. Hydrangeas have historically been linked to love and gratitude, and were often used to communicate heartfelt emotions during the Victorian era. The color of the hydrangea flower can convey different meanings, with pink symbolizing heartfelt emotions, blue signifying frigidity, and purple representing a desire to deeply understand someone.
3. While most hydrangeas are known for their vibrant and eye-catching blooms, the true flower of the hydrangea is actually a cluster of small, insignificant flowers in the center of the head, surrounded by showy petals called bracts.
4. The color of some hydrangea varieties can change based on the acidity of the soil. In more acidic soil, hydrangeas tend to produce blue flowers, while alkaline soil produces pink flowers. This fascinating phenomenon can be manipulated by adding specific amendments to the soil, allowing gardeners to alter the color of their hydrangeas.
5. Hydrangeas are not only beautiful but also have potential therapeutic benefits. The leaves of some hydrangea cultivars, especially Hydrangea paniculata, have been used in traditional medicine for centuries. These leaves are believed to possess diuretic and anti-inflammatory properties, and have been used in remedies for urinary tract infections and kidney ailments.
Propagating Hydrangeas From Cuttings
Hydrangeas are beloved flowering shrubs known for their stunning blooms and vibrant colors. While many gardeners enjoy purchasing established hydrangea plants from nurseries, propagating hydrangeas from cuttings can be a rewarding and cost-effective way to build up the number of plants in your garden. By following a few simple steps, you can successfully grow new hydrangea plants from cuttings and expand your collection.
Taking cuttings from hydrangeas is relatively easy and generally done in either early spring or late summer. It’s essential to select stems that did not flower during the current season. By taking cuttings from non-flowering stems, you ensure that the energy of the plant is concentrated on root development rather than flower production. Before you begin, ensure you have clean, sharp pruners that have been disinfected to prevent the transfer of diseases.
Best Time And Method For Taking Cuttings
Late summer is widely considered the best time to take cuttings from hydrangeas for propagation. During this period, the stems are semi-ripe, which means they possess a woody base and a soft, flexible tip. This combination makes them ideal for rooting without the risk of rot when inserted into compost.
When selecting stems for your cuttings, it’s crucial to choose healthy and vigorous ones. Look for stems that are free from diseases and have no signs of damage. Additionally, ensure the selected stems have at least four to six inches in length and two nodes below the top set of leaves. These nodes are essential for the development of roots.

Prep And Care For Cuttings Before Planting
Once you’ve taken the cuttings, it’s important to prepare them for planting. Begin by removing the lower leaves, as they will be buried in the potting medium and might lead to rot. You can also halve the top leaves to reduce moisture loss and help the cutting focus its energy on developing roots.
To boost the chances of successful propagation, keep the cuttings moist and out of direct sunlight until they are ready to be planted. Prepare pots filled with fresh, moistened potting mix or vermiculite to provide an ideal rooting environment. It’s recommended to slightly moisten the base of each cutting before dipping it into a rooting hormone to encourage root development.
Proper Planting Technique For Hydrangea Cuttings
To plant your hydrangea cuttings, insert them into the potting medium, ensuring that the base of the top leaves is at the same level as the surface. Firmly plant them to ensure good contact between the cutting and the medium. Once all the cuttings are planted, drain any excess water from the pots and cover them with a translucent plastic dome or tent. This cover helps create a humid environment that promotes root growth.
When it comes to placement, it’s best to keep the cuttings in an area with bright shade or indirect light indoors. Maintain proper moisture levels by watering the pots when the surface of the potting medium becomes dry. However, be careful not to overwater, as this can lead to rot. Adequate drainage in the pots is crucial to prevent waterlogging.

Maintaining And Monitoring Cuttings
After planting, hydrangea cuttings require ongoing care and monitoring to ensure successful propagation. Inspect the cuttings regularly for signs of wilting or diseases. Address any issues promptly to prevent potential damage.
The cuttings should show new top growth and firm resistance from the roots after approximately six weeks. This indicates successful rooting and readiness for the next phase.
Transplanting And Overwintering Hydrangea Cuttings
Once the cuttings have rooted and demonstrate healthy growth, they can be transplanted into individual pots or directly into the garden. This should be done in spring when the cuttings start to grow vigorously. Gently remove the rooted hydrangea cuttings from their pots and transfer them to larger containers or their planned garden location.
During the winter months, it’s important to protect your propagated hydrangea cuttings from harsh weather conditions. To do this, consider overwintering them in a cold frame or a similar protective structure. This will shield them from frost and ensure their survival until the next growing season.
propagating hydrangeas from cuttings is an enjoyable and effective way to expand your hydrangea collection. By following the proper steps, including taking cuttings at the right time, providing adequate care and monitoring, and ensuring appropriate transplanting and overwintering, you can successfully propagate and nurture these beautiful flowering shrubs. With patience and attention, you’ll soon have a bountiful garden filled with stunning hydrangea blooms.
Frequently Asked Questions
Do hydrangeas propagate easily?
Hydrangeas have a remarkable ability to propagate easily through their various cuttings. They can be started from softwood cuttings during early spring or semi-hardwood cuttings during late summer. This flexibility allows for a higher success rate in propagating hydrangeas, whether you are a beginner or experienced gardener. By utilizing these simple techniques, one can easily create new hydrangea plants to enhance their garden and enjoy this beautiful flowering plant.
What is the best time of year to take hydrangea cuttings?
The ideal time for taking hydrangea cuttings is during the late-summer season. At this point, the cuttings are considered semi-ripe, striking a balance between the current year’s growth and the development of a woody base. Their soft and pliable tips make them perfect for propagation, ensuring successful rooting and healthy growth. By taking hydrangea cuttings in late-summer, you maximize your chances of successfully propagating new plants and expanding your hydrangea collection.
How do you multiply hydrangeas?
To multiply hydrangeas, one method is through taking cuttings from a small branch. By using pruning shears or a garden knife, a cutting can be carefully removed. Another method involves bending a stem of a hydrangea plant and allowing it to rest on the ground, where it can naturally develop roots from one of the leaf nodes. These techniques offer simple ways to propagate hydrangeas and create new plants either through cuttings or by encouraging stem growth.
How fast do hydrangeas propagate?
Hydrangeas have a moderate rate of propagation, with cuttings typically taking 2-3 weeks to root. These cuttings are made from semi-ripe stems, which have a green and supple top and a woody base that prevents rotting in the compost. The process of rooting allows the cuttings to establish their own root system, enabling them to grow into new hydrangea plants. With patience and proper care, hydrangeas can propagate relatively quickly through cuttings.
