It’s important to keep the soil consistently moist but not waterlogged. After a few weeks, the cutting should start developing roots. Once the roots are well-established, the new plant can be transplanted into a larger pot or the garden.

Stem cutting propagation is a reliable and efficient method that allows you to create identical clones of your favorite hydrangea plants.

Division

Division is another propagation method that is particularly suitable for mature hydrangea plants that have formed clumps or dense root systems. It involves separating the plant into multiple sections, each with its own set of roots and shoots. Here’s how you can propagate hydrangeas through division:

1. Selecting the Plant: Choose a mature hydrangea plant that has several stems emerging from the ground. This indicates that the plant has formed multiple crowns, making it suitable for division.
2. Preparing the Plant: Dig up the entire plant carefully, taking care not to damage the roots. Gently shake off excess soil to expose the root structure. If the plant has a dense root system, you may need to use a sharp and sterilized knife or garden spade to divide it into smaller sections.
3. Separating the Sections: Once you have identified sections with their own set of roots and shoots, gently pull them apart or use a sharp tool to separate them. Ensure that each section has a sufficient root mass and a healthy portion of stems.
4. Replanting the Divisions: Dig individual holes in the desired location for each division, ensuring that they are appropriately spaced. Place each division in its respective hole and backfill with soil, gently firming it around the roots. Water the newly planted divisions thoroughly to settle the soil.

Division allows you to rejuvenate overcrowded hydrangeas, propagate multiple plants from a single specimen, and promote healthier growth overall.
