How to Propagate Oakleaf Hydrangea?

The oakleaf hydrangea, with its striking foliage and beautiful blooms, is a popular ornamental shrub in many gardens. If you have one of these lovely shrubs and wish to create more or share its beauty with others, propagation is the way to go. This guide will walk you through the art of propagating oakleaf hydrangea, allowing you to multiply your plants or spread their charm to different areas. By understanding the methods involved in propagation, you’ll unlock the potential to create new thriving oakleaf hydrangea plants, ensuring a bountiful display of their unique beauty in your garden.

Methods of Propagation

There are two primary methods for propagating oakleaf hydrangea: stem cuttings and division. Each method offers its own set of advantages and is suited for different situations. Stem cuttings are ideal for producing new plants that are genetically identical to the parent plant. This method can be performed during the growing season, typically in late spring or early summer. On the other hand, division involves splitting the plant into smaller sections, which can be particularly useful for rejuvenating established oakleaf hydrangeas. The ideal time for division is early spring, just as the new growth emerges. You can choose the method that best suits your goals and the resources available to you. Whether you prefer starting from cuttings or dividing an existing plant, the end result will be more beautiful oakleaf hydrangeas to enjoy in your garden.

Propagating from Stem Cuttings

To propagate oakleaf hydrangea from stem cuttings, you’ll need to start by taking cuttings from a healthy, mature plant. Here’s how to do it:

  1. Select a healthy stem: Choose a non-flowering stem with at least two leaf nodes (where leaves emerge) near the tip.
  2. Make the cut: Use sharp, clean pruning shears to cut the stem just below a leaf node, creating a cutting that’s about 4-6 inches long.
  3. Remove lower leaves: Strip away the lower leaves to leave only a few at the top.
  4. Rooting hormone (optional): While it’s not necessary, you can dip the cut end of the stem in rooting hormone to encourage root development.
  5. Plant the cutting: Place the cutting in a pot filled with a well-draining potting mix. Make a small hole for the cutting and ensure it’s planted about 2 inches deep.
  6. Maintain humidity and light: Cover the pot with a plastic bag or plastic wrap to create a mini greenhouse, keeping the humidity high. Place it in indirect light to encourage rooting.
  7. Keep the soil consistently moist but not waterlogged. Roots should form in a few weeks to a couple of months.

Propagating through Division

Propagating oakleaf hydrangea through division is another effective method. Here’s how to do it:

  1. Choose the right time: Early spring, just as new growth begins, is the ideal time for division.
  2. Dig up the plant: Carefully dig up the entire oakleaf hydrangea, trying not to damage the roots too much.
  3. Separate the sections: Using a sharp shovel or a pair of pruners, divide the plant into sections, ensuring that each section has its own set of roots.
  4. Replant the divisions: Plant each division in a new location or pot, ensuring that the roots are well covered with soil.
  5. Water generously: Water the newly planted divisions thoroughly to help them settle in their new spots.
  6. Maintain care: Continue to care for the divided sections as you would for established oakleaf hydrangea plants. Keep the soil consistently moist, provide the right light conditions, and offer proper care to encourage healthy growth.

Whether you choose stem cuttings or division, these methods are both effective ways to propagate oakleaf hydrangea and expand your garden’s beauty with new plants.

Planting and Caring for New Plants

After successfully propagating oakleaf hydrangea through either stem cuttings or division, the next crucial step is to ensure the health and vitality of your new plants. Here’s how to plant and care for them:

  1. Select a suitable location: Choose a spot with well-drained soil and partial shade. Oakleaf hydrangeas thrive in locations with morning sun and afternoon shade.
  2. Dig a hole: Dig a hole that’s slightly larger than the root ball of your new plant. Ensure the plant is positioned at the same depth as it was in its original pot or the division.
  3. Backfill with soil: Fill the hole with a mixture of the existing soil and organic matter like compost or peat moss. This helps improve soil quality.
  4. Water thoroughly: Water the newly planted oakleaf hydrangea generously to help it settle into its new home.
  5. Mulch: Apply a layer of mulch around the plant to retain moisture, suppress weeds, and regulate soil temperature.
  6. Regular care: Oakleaf hydrangeas prefer consistently moist soil, so water them during dry periods. Prune as needed to remove dead or damaged growth and promote a well-shaped plant.


Propagation of oakleaf hydrangea offers a wonderful way to increase the beauty of your garden or share these lovely plants with friends and family. By following the specific methods of propagation, planting new plants, and providing proper care, you can enjoy the elegance and charm of these hydrangeas in various areas of your garden.
