How To Grow New Hydrangeas From Cuttings

Growing new hydrangeas from cuttings is an excellent way to propagate your favorite hydrangea plants. Here’s a step-by-step guide on how to do it:

Materials you’ll need:

  1. Healthy hydrangea plant
  2. Pruning shears
  3. Clean pot or container
  4. Well-draining potting mix
  5. Rooting hormone (optional)
  6. Clear plastic bag or plastic wrap
  7. Watering can or spray bottle

Step 1: Select the right time Choose a time when the hydrangea plant is actively growing, typically in spring or early summer. This is when the stems are soft and flexible, making them more likely to root successfully.

Step 2: Choose a healthy stem Look for a stem on the hydrangea plant that is approximately 4-6 inches long. It should be relatively young, green, and free from any diseases or damage.

Step 3: Prepare the cutting Using clean pruning shears, make a diagonal cut just below a leaf node (the point where leaves emerge from the stem). Remove any leaves from the lower part of the stem, leaving a few leaves at the top.

Step 4: Apply rooting hormone (optional) Dip the cut end of the stem into a rooting hormone powder or gel. This step can help stimulate root growth and increase the chances of successful rooting.

Step 5: Plant the cutting Fill a clean pot or container with a well-draining potting mix. Make a hole in the soil with a pencil or your finger, and gently insert the cut end of the stem into the hole. Firmly press the soil around the stem to secure it in place.

Step 6: Water the cutting Water the soil thoroughly to settle it around the stem. Ensure that the soil remains moist but not waterlogged throughout the rooting process. You can use a watering can or a spray bottle to water the cutting gently.

Step 7: Create a mini-greenhouse Cover the cutting and the pot with a clear plastic bag or plastic wrap to create a humid environment. This will help retain moisture and promote root growth. Make sure the plastic doesn’t touch the leaves by using stakes or toothpicks to create a tent-like structure.

Step 8: Provide the right conditions Place the pot in a warm, bright location with indirect sunlight. Avoid direct sunlight, as it can cause excessive heat and damage the cutting. Maintain a temperature of around 65-75°F (18-24°C) for optimal rooting.

Step 9: Monitor and care for the cutting Check the cutting regularly to ensure the soil remains moist. If it feels dry, mist it with water to increase humidity. Avoid overwatering, as this can lead to rot. After a few weeks, gently tug on the stem to check for resistance, indicating root development.

Step 10: Transplant the rooted cutting Once the cutting has developed a healthy root system, usually after several weeks to a few months, it’s ready to be transplanted. Carefully remove the plastic cover and gently transfer the rooted cutting to a larger pot or your desired planting location in the garden.

Remember to continue providing proper care, such as regular watering and suitable sunlight conditions, to help the new hydrangea plant thrive.

Note: It’s important to keep in mind that not all hydrangea varieties root easily from cuttings. Some may require different propagation methods, such as layering or grafting.
