Grow Your Garden With Just One Plant
Hydrangeas are some of the most beloved flowering shrubs in home gardens—and for good reason. Their lush blooms and vibrant colors make any space feel more alive. What’s even better? You can multiply your hydrangeas easily without spending a dime on new plants.
This guide walks you through the simple, step-by-step process of propagating hydrangeas using cuttings. Whether you’re new to gardening or a seasoned green thumb, this method is beginner-friendly and highly rewarding.
Step 1: Choose a Healthy Stem
The success of propagation begins with selecting the right stem.
Look for a non-flowering stem that’s green, flexible, and around 4 to 6 inches long (10–15 cm). This is often called a “softwood” cutting—young, but mature enough to grow roots. Ideally, the stem should have 2 to 3 visible leaf nodes, which are the spots where leaves grow from the stem.
Why not a flowering stem?
Flowering stems divert energy to blooming rather than root development. Non-flowering stems are more likely to root quickly and grow into healthy plants.
Step 2: Make a Clean Cut
Once you’ve found the right stem, use clean, sharp scissors or pruning shears to make your cut just below a node. Nodes are essential because they’re where new roots will emerge.
Next, remove the bottom leaves to expose the nodes, and leave only 1 or 2 leaves at the top of the cutting. This helps the plant conserve energy and focus on root growth.
Pro Tip: If the remaining leaves are large, you can snip them in half to reduce moisture loss without removing them entirely.
Step 3: (Optional) Use Rooting Hormone
While not absolutely necessary, applying a rooting hormone to the cut end of the stem can boost your chances of success. Rooting hormone helps stimulate root development and protects the cutting from rot or disease.
If you don’t have rooting hormone on hand, no worries—many gardeners see great results without it!
Step 4: Plant Your Cutting
Now it’s time to plant.
Fill a small pot with moist, well-draining potting soil—something rich in organic material but light enough to allow airflow. Make a small hole in the center and gently insert your cutting, with the exposed node buried in the soil.
Press the soil around the stem lightly to secure it in place, making sure not to crush the delicate cutting.
Step 5: Create a Humid Environment
Hydrangea cuttings love humidity.
To maintain the ideal environment, cover the pot with a clear plastic bag or a mini greenhouse dome. This traps moisture and keeps the cutting from drying out while roots are forming.
Place your covered pot in a bright, warm area, but keep it out of direct sunlight, which can overheat the plant or cause leaf burn.
Tip: Open the bag every couple of days for a few minutes to allow air circulation and prevent mold growth.
Step 6: Water and Wait
Hydration is key—but so is balance. Keep the soil consistently moist, not soggy. Overwatering can lead to root rot, especially in the early stages.
With the right conditions, your hydrangea cutting should begin developing roots within 2 to 4 weeks.
To test for root growth, give the cutting a very gentle tug. If there’s resistance, roots are forming!
🌸 After Rooting: Transplant and Care
Once your cutting has a solid root system and starts to show new growth, it’s ready for its next stage.
You can now transplant it into a larger pot or directly into your garden. If planting outdoors, choose a spot with morning sun and afternoon shade—hydrangeas love indirect light.
Be sure to water regularly, especially during dry spells, and protect young plants from harsh sun and strong wind while they establish.
