How to Multiply Hydrangeas in a Few Simple Steps

3. Propagating Hydrangeas by Layering

Step 1: Select a Low-Growing Branch

• Layering is a technique where a branch of the plant is bent down to the ground and encouraged to root while still attached to the parent plant.
• Choose a healthy, flexible branch that is close to the ground.

Step 2: Prepare the Ground

• Dig a shallow trench about 2-3 inches deep where the branch will touch the ground.
• Loosen the soil in the trench and mix in some organic matter to improve drainage and fertility.

Step 3: Layer the Branch

• Gently bend the branch down into the trench, ensuring that at least one leaf node touches the soil.
• Remove any leaves that would be buried.
• Bury the leaf node with soil, leaving the tip of the branch exposed above ground.
• Use a small rock, a piece of wire, or a landscape staple to hold the branch in place under the soil.

Step 4: Encourage Rooting

• Water the area well and keep the soil moist throughout the rooting process.
• It can take several months for roots to develop. By the following spring, the layered branch should have formed its own root system.

Step 5: Sever and Transplant

• Once the branch has rooted, sever it from the parent plant using clean pruning shears.
• Carefully dig up the new plant, keeping as much of the root system intact as possible.
• Transplant the new hydrangea to its permanent location and water it well.

4. Caring for Your New Hydrangeas

• Watering: Newly propagated hydrangeas need consistent moisture, especially during their first growing season. Water deeply and regularly, ensuring the soil remains moist but not waterlogged.
• Mulching: Apply a layer of mulch around the base of the plant to retain moisture and regulate soil temperature.
• Fertilizing: Fertilize your hydrangeas in early spring with a balanced, slow-release fertilizer to promote healthy growth and abundant blooms.
• Pruning: Prune your hydrangeas according to their type to encourage vigorous growth and flowering.

Conclusion

Propagating hydrangeas is a simple and effective way to expand your garden or share these beautiful plants with others. By following these steps, you can successfully multiply your hydrangeas and enjoy their stunning blooms for years to come. Whether you choose to propagate by cuttings or layering, the process is rewarding and ensures you’ll have plenty of hydrangeas to enjoy.
