How Do I Take a Cutting From a Hydrangea to Propagate this Beautiful Flower?
How Do I Take a Cutting From a Hydrangea?
To take a cutting from a hydrangea, start by selecting a stem that did not flower to ensure enough energy for root development.
Clean and disinfect your pruners before cutting a 4-6 inch section of stem with at least two nodes below the top leaves.
Remove the lower leaves and leave the top set of leaves intact or halve them if they are large.
Moisten potting mix or vermiculite in pots and dip the base of each cutting in rooting hormone.
Plant the cutting in the potting mix up to the base of the top leaves and firm the medium around it.
Keep the cuttings moist and protected from direct sunlight by covering them with a plastic dome or creating a makeshift tent.
After 2 to 3 weeks, remove the cover once roots have formed.
Keep the cuttings in a bright shade or indirect light indoors.
Water the pots when the surface is dry, avoiding overwatering.
After about 6 weeks, when new top growth appears and the roots have firm resistance, the cuttings can be transplanted into individual pots or into a protected area of the garden.
Finally, plant the new hydrangeas in the garden the following spring.

Did You Know?
1. The process of taking a cutting from a hydrangea is called “softwood cutting.” It involves using a young, flexible stem for propagation.
2. Hydrangea cuttings root best when taken in the early morning or late evening when the plant is not under stress from the sun’s heat.
3. To increase the success rate of hydrangea cuttings, it is recommended to dip the cut ends in a rooting hormone before planting them in a potting mix.
4. Some hydrangea varieties have specific requirements for successful propagation. For instance, the popular mophead hydrangeas (Hydrangea macrophylla) can be challenging to propagate, whereas the oakleaf hydrangeas (Hydrangea quercifolia) are more straightforward.
5. It is important to monitor the humidity levels when propagating hydrangeas from cuttings. One useful trick is to place the cuttings under a transparent plastic bag or cover them with a cloche to create a mini greenhouse effect.

Choosing The Right Time And Type Of Stem For Your Cuttings
Timing is crucial when it comes to taking cuttings from hydrangeas. The best time to do so is in early spring when the plant is starting to awaken from its winter dormancy or in late summer when the plant has entered its semi-hardwood growth phase. During these periods, the plant is actively growing, which increases the chances of successful rooting.
When selecting stems for your cuttings, it is important to choose ones that did not produce flowers. This ensures that the energy of the plant is focused on root development rather than flower production. Look for healthy stems that have not yet flowered, as these will have the highest chance of success.
Step-By-Step Instructions For Taking And Preparing The Cuttings
Before taking cuttings, it is crucial to clean and disinfect your pruners to prevent the spread of diseases. Using rubbing alcohol or a disinfecting solution, wipe down the pruners before and after each cut.
To take the cuttings, select a 4-6 inch section of stem with at least two nodes below the top leaves. Nodes are the points on the stem where leaves and branches emerge. Using your pruners, make a clean cut just below a node.
Remove the lower leaves from the cutting, leaving only the top set of leaves intact. If the top leaves are large, you can halve them to reduce water loss. This will help the cutting conserve energy while it develops roots.
Prepare pots with moistened potting mix or vermiculite. Make sure the mix is damp but not overly wet. Dip the base of each cutting in rooting hormone, which is optional but may increase the chances of successful rooting.
Make a hole in the potting medium and insert the cutting up to the base of the top leaves, ensuring that the node where the leaves were removed is covered. Gently firm the medium around the cutting to provide stability.
Creating The Ideal Environment For Successful Rooting
To create the ideal environment for successful rooting, it is essential to keep the cuttings moist and protected from the sun. Hydrangea cuttings are sensitive to sunlight and can easily become too hot, which may hinder rooting.
Cover the cuttings with a plastic dome or create a makeshift tent using plastic wrap or a plastic bag supported by bamboo or pencils. This will create a small greenhouse-like environment that helps maintain humidity and avoids excessive heat exposure.
It is recommended to place the cuttings in a bright area with indirect light or bright shade indoors. Direct sunlight can be too intense for the fragile cuttings, especially when covered. By providing the right light conditions, you will encourage healthy growth without risking sunburn or heat stress.
Transplanting And Caring For Your New Hydrangeas
After approximately 6 weeks, new top growth will begin to emerge, indicating that the cuttings have successfully generated roots. You can gently tug on the cuttings to check for firm resistance, a sign that the roots have developed well.
At this stage, the cuttings can be carefully transplanted into individual pots or planted in a protected area of the garden with well-draining soil. Ideally, the new hydrangeas should be transplanted before the first frost hits, allowing them enough time to settle in before the winter.
When planting in pots or the garden, ensure adequate drainage to prevent waterlogged roots and potential rot. Water the plants when the surface of the potting mix or soil feels dry, but be cautious not to overwater. Overwatering can lead to root rot and compromise the health of the new plants.
By the following spring, your rooted hydrangea cuttings can be planted in their permanent locations in the garden. With proper care and attention, they will continue to grow and produce the beautiful flowers hydrangeas are known for.
Growing hydrangeas from cuttings is an easy and rewarding way to propagate these stunning flowers. By following these step-by-step instructions and providing the right environment and care, you can enhance your garden with more of these delightful shrubs and enjoy their vibrant blooms year after year.

Frequently Asked Questions
Can you grow a hydrangea from a cutting?
Yes, it is indeed possible to grow a hydrangea from a cutting. Hydrangeas are a versatile plant that can be propagated through softwood or semi-hardwood cuttings. Softwood cuttings can be taken in early spring when the plant is beginning to leaf out, while semi-hardwood cuttings can be taken in late summer from first-year growth that has developed a semi-woody base. By carefully selecting and rooting these cuttings, it is possible to successfully grow a new hydrangea plant.
Will hydrangea cuttings root in water?
Hydrangea cuttings are unlikely to root successfully if placed in water due to their woody nature. To propagate hydrangeas, it is best to insert the cuttings into a pot of gritty compost and maintain moisture in a propagator until root development occurs, typically within six weeks. To protect the cuttings during winter, they can be kept in a cold frame or a similar sheltered environment. By following these steps, one can increase the chances of successful propagation.
How do you propagate a hydrangea paniculata?
To propagate a Hydrangea paniculata, one can employ a method known as stem cutting. This process involves carefully selecting and cutting shoot tips from the plant during the months of June and July. These shoot tips should be around 10 to 15 centimeters long, healthy, and only slightly woody, without any flower buds. Once the shoot tips are selected, all but the top pair of leaves should be removed, and then they can be placed in growing containers filled with substrate. With proper care and nurturing, these cuttings have the potential to develop into entirely new Hydrangea paniculata plants.
What is the best way to root a hydrangea cutting?
The best way to root a hydrangea cutting is by planting it in a cutting-friendly, well-draining mix made for seed starting. Since hydrangea cuttings do not root well in water, it is important to use a soil mix that includes materials like coir, sand, or peat moss. When planting the cutting, make sure to place it into the soil up to the edge of the bottom set of leaves. This will provide the cutting with the necessary support and encourage root growth.
