Rooting hydrangea cuttings in water can be a successful method for propagating new plants. Here’s a step-by-step guide on how to do it:
1. Select a healthy branch: Choose a branch that is young and healthy, preferably from the current year’s growth. The branch should have at least one leaf node, which is a small bump where a leaf emerges from the stem.
2. Prepare the cutting: Using a clean, sharp pair of pruning shears, take a small cutting from the branch. Make a clean cut just below a leaf node, ensuring that the cutting is about 4-6 inches long. Remove any leaves from the lower half of the cutting, leaving a few leaves at the top.
3. Scrape the bark: Gently scrape off a small section of the bark from the underside of the cutting, near the cut end. This will expose the cambium layer, which is where the roots will emerge.
4. Prepare a vessel: Fill a clean glass or jar with room temperature water. Make sure the water level is deep enough to submerge the cut end of the cutting but not so deep that it covers the leaves.
5. Place the cutting in water: Carefully place the cut end of the hydrangea cutting into the water, ensuring that the scraped area is fully submerged. The leaves should be above the waterline.
6. Provide the right conditions: Place the vessel in a bright location with indirect sunlight. Avoid placing it in direct sunlight as this can cause the water to heat up and potentially damage the cutting. Maintain a consistent temperature between 65-75°F (18-24°C).
7. Monitor and change water: Check the water level regularly and make sure it remains at the appropriate level. If the water becomes cloudy or discolored, replace it with fresh, room temperature water.
8. Wait for root development: Over time, you should start to see roots forming from the scraped area of the cutting. This process can take several weeks or even a couple of months, so patience is key. Once the roots are about 1-2 inches long, the cutting is ready for planting.
9. Transplant the cutting: When the roots have developed, it’s time to transplant the cutting into soil. Prepare a small pot with well-draining potting mix and make a hole with your finger. Gently remove the cutting from the water, being careful not to damage the delicate roots. Place the cutting in the hole, ensuring that at least one leaf node is buried in the soil. Lightly tamp down the soil around the cutting to secure it.
10. Provide appropriate care: Place the potted cutting in a location with indirect sunlight and keep the soil consistently moist, but not waterlogged. Mist the leaves occasionally to maintain humidity and prevent wilting. As the cutting establishes, you can gradually reduce the frequency of watering.
Remember, not all cuttings will successfully root in water, but hydrangeas are known to root well using this method. It’s always a good idea to take multiple cuttings to increase your chances of success. Good luck with your propagating endeavors!
