How to Propagate Hydrangeas from Cuttings: A Step-by-Step Guide

Hydrangeas are a stunning and versatile group of flowering plants that add a burst of color and charm to any garden. Known for their large, globe-like flower heads, hydrangeas can be found in a variety of vibrant hues, including shades of blue, pink, white, and purple. These colors can even change based on the soil's pH level, with more acidic soils producing blue flowers and alkaline soils yielding pink blossoms. The lush clusters of blooms are often accompanied by dark green, serrated leaves, creating a striking contrast that enhances their visual appeal. Hydrangeas thrive in both sunny and partially shaded areas, making them a popular choice for a range of garden settings, from borders and hedges to standalone specimen plants. With their long-lasting flowers that typically bloom from late spring to early fall, hydrangeas provide continuous beauty throughout the growing season. Their adaptability, combined with their showy, voluminous blooms, makes hydrangeas a beloved favorite among gardeners and landscapers alike.

Propagating hydrangeas from cuttings is a rewarding and cost-effective way to expand your garden. With a little patience and the right technique, you can grow new hydrangea plants from your existing ones. Here's a comprehensive guide to help you through the process.

Materials Needed

  • Sharp pruning shears or scissors
  • Rooting hormone (optional but recommended)
  • Small pots or containers
  • Potting mix (preferably a mix of sand and peat moss or perlite)
  • Plastic bag or a clear plastic cover
  • Watering can or spray bottle

Step-by-Step Guide

1. Choose the Right Time
The optimal period for taking hydrangea cuttings is late spring to early summer. During this time, the plant is actively growing, which increases the likelihood of successful rooting. The warmer temperatures and longer daylight hours provide the ideal conditions for new roots to develop. Avoid taking cuttings during the dormant season, as the plant's energy is focused on surviving rather than growing.

2. Select Healthy Cuttings
Choose a healthy, non-flowering stem. The best cuttings come from new growth, as this wood is more likely to root than older, woody stems. Cut a section about 4-6 inches long, ensuring it has at least one pair of leaves at the top and a few leaf nodes along the stem. These nodes are crucial as they are the points from which new roots will emerge. Avoid using stems that show any signs of disease or damage.

3. Prepare the Cuttings
Once you have your cuttings, remove the lower leaves to leave a bare stem. This prevents the leaves from rotting when planted in the soil. Only keep the top pair of leaves, and if they are large, cut them in half to reduce water loss through transpiration. This step helps the cutting focus its energy on root development rather than maintaining large leaves.

4. Dip in Rooting Hormone (Optional)
To enhance the chances of successful rooting, dip the cut end of the stem into rooting hormone powder or gel. This step is optional but recommended, as rooting hormones contain growth regulators that stimulate root formation. This can significantly speed up the rooting process and improve the overall success rate of your cuttings.

5. Plant the Cuttings
Prepare small pots or containers with a well-draining potting mix, such as a blend of sand and peat moss or perlite. Make a hole in the center of the potting mix using a pencil or stick, then gently insert the cutting into the hole. Firm the soil around the cutting to ensure it stands upright and is supported by the soil. Proper planting depth is crucial; bury the cutting deep enough to cover the lower nodes but leave the top pair of leaves exposed.

6. Water and Cover
After planting, water the potting mix thoroughly to ensure good soil-to-stem contact and to settle the soil around the cutting. To maintain high humidity, which is crucial for rooting, cover the pot with a plastic bag or a clear plastic cover. This creates a mini greenhouse effect, trapping moisture and warmth. Ensure the plastic does not touch the leaves; use sticks or small stakes to hold it up if necessary.

7. Provide the Right Environment
Place the covered pots in a warm, bright location, but avoid direct sunlight which can overheat the cuttings and cause them to dry out. Maintain high humidity by regularly misting the cuttings or ensuring the soil stays moist but not waterlogged. The ideal temperature range for rooting hydrangea cuttings is between 65-75°F (18-24°C).

8. Monitor and Wait
Regularly check the cuttings for signs of new growth, which indicates that rooting is taking place. This process can take several weeks, usually around 4-6 weeks. Be patient and avoid disturbing the cuttings too much during this period.
9. Transplanting
Once the cuttings have developed a good root system, they can be transplanted into larger pots or directly into the garden. Before planting them in their permanent location, gradually acclimate the young plants to outdoor conditions. This can be done by slowly increasing their exposure to outdoor conditions over a week or two.


By following these steps, you can successfully propagate hydrangeas from cuttings and enjoy a flourishing garden. With the right materials, timing, and care, you'll have new hydrangea plants ready to thrive. Propagation is not just a cost-effective method but also a fulfilling way to expand your garden and share your love for hydrangeas with friends and family. Happy gardening!

Frequently Asked Questions (FAQs)

Q1. Can I propagate hydrangeas in water?
A1. Yes, you can propagate hydrangeas in water by placing the cut end in a jar of water and changing the water regularly until roots develop.
Q2.  How long does it take for hydrangea cuttings to root?
A2.  Hydrangea cuttings typically take about 4-6 weeks to develop roots, depending on the conditions provided.
Q3. Do hydrangea cuttings need direct sunlight?
A3. No, hydrangea cuttings should be kept in bright, indirect light to prevent them from drying out and overheating.
Q4. Can I use garden soil for planting hydrangea cuttings?
A4. It's best to use a well-draining potting mix rather than garden soil, which can be too dense and retain too much moisture.
Q5. Is it necessary to use rooting hormone?
A5. While not mandatory, using rooting hormone can enhance the rooting success rate and speed up the process.
Q6. What type of hydrangeas can be propagated from cuttings?
A6. Most hydrangea varieties, including bigleaf, panicle, and smooth hydrangeas, can be propagated from cuttings.
Q7. How do I know if my hydrangea cuttings have rooted?
A7. Gently tug on the cutting; resistance indicates root development. Visible new growth is also a good sign.
Q8. Can I take cuttings from hydrangeas in fall?
A8. It's possible but less ideal. Cuttings taken in late spring to early summer have a higher success rate due to active growth.
