Propagate hydrangeas is a simple and rewarding way to grow new plants. Hydrangeas are popular garden plants known for their beautiful blooms and adaptability. Growing new hydrangea plants from cuttings in water is a simple and affordable method that anyone can try. It requires only basic materials, like a healthy cutting and a jar of water, making it perfect for new and experienced gardeners. With the proper care, such as keeping the water fresh and cutting in indirect sunlight, roots can start to grow within a few weeks. While hydrangeas tend to root more effectively in soil, propagating them in water is an easy and enjoyable way to expand your garden.

1: Select the Right Cutting
To start, choose a healthy stem from your hydrangea plant. It’s best to pick a non-flowering stem since flowering stems focus more on blooming than root growth. Look for a branch that didn’t bloom this year, as it is more likely to develop roots. Use clean, sharp pruning shears to cut a piece about 5-6 inches long. Cut just below a leaf node, which is the small bump where leaves grow from the stem. This is where the roots will form during propagation.
2: Prepare the Cutting
Once you have your cutting, remove the leaves from the lower two nodes to prevent them from rotting in the water. Rotting leaves can introduce bacteria, which might harm the cutting. Next, trim the remaining leaves in half to reduce water loss. Large leaves lose more moisture, which can slow down root development. By focusing the plant’s energy on growing roots, you increase the chances of success.
3: Place the Cutting in the Water
Take a clear jar or glass and fill it with clean, filtered water. Avoid using tap water if it’s heavily chlorinated, as this can damage the cutting. Place the cutting in the jar, ensuring that the lower nodes are submerged while the leaves stay above water. Put the jar in a bright spot that gets indirect sunlight. Direct sunlight can heat the water and harm the cutting, so choose a location with gentle, steady light.
4: Monitor and Maintain
Keep a close watch on the cutting and the water it’s in. Make sure to replace the water every two to three days to keep it fresh and free from bacteria that could harm the cutting. Always use clean, filtered water to ensure the lower nodes stay fully submerged. Check the cutting regularly for signs of root growth, which usually begins within two to four weeks. Remember, factors like temperature and humidity can affect the rooting process, so maintain a stable environment and give it time to develop.
5: Transition to Soil
When the roots are about 2-3 inches long, it’s time to move the cutting to soil. Choose a small pot with well-draining soil to avoid waterlogging. Handle the roots gently, as they are delicate and can easily break. Plant the cutting so the roots are covered, but don’t bury it too deeply. Water the soil lightly and place the pot in a spot with indirect light. Gradually introduce the plant to outdoor conditions by exposing it to more sunlight over time.
