3. Planting the Cutting: Insert the prepared cutting into a moistened, well-draining propagation medium such as perlite, vermiculite, or a mix of peat and perlite. Enclose the cutting and pot in a clear plastic bag or place in a propagator to maintain high humidity levels.

4. Rooting and Growth: Place the propagated cuttings in a warm, bright location with indirect sunlight. Monitor the moisture levels in the propagation medium and maintain high humidity until roots develop, at which point the new plants can be potted up individually.

Layering

Layering is another effective method for propagating bigleaf hydrangeas. This technique involves encouraging a stem on the parent plant to develop roots while it is still attached, resulting in a new, independent plant. Layering can be accomplished using the following steps:

1. Selecting a Stem: Choose a healthy, flexible stem from the parent plant and make a shallow cut on the underside of the stem where it touches the soil.

2. Encouraging Rooting: Apply a small amount of rooting hormone to the wounded area and then gently bury the wounded section of the stem in the soil, ensuring that it is in contact with the moist soil.

3. Supporting Growth: Secure the layered stem with a U-shaped wire or a small stake to prevent it from springing back up. Keep the soil consistently moist and monitor the development of roots.

4. Separating the New Plant: Once roots have developed, the layered stem can be separated from the parent plant and potted up as a new, independent specimen.

By employing these propagation techniques, you can multiply your inventory of bigleaf hydrangeas and share the beauty of these plants with fellow gardeners.
