If you’re a fan of hydrangeas and want to expand your collection, propagating them from cuttings is a simple and rewarding process. Hydrangeas can be propagated at any time of the year, but it is best to do it in the spring or early summer when the weather is warm and the plants are actively growing. To get started, you’ll need a pair of sharp clippers, a well-hydrated parent plant to take cuttings from, and a potting mix that is suitable for rooting.
When selecting a branch to propagate, look for softwood stems that are about 6-8 inches long. Softwood stems are green and flexible, whereas woody stems are brown and stiff. Make a clean cut just below a set of leaves, and remove the bottom set of leaves to expose a node.
To improve your chances of success, consider using a rooting hormone to help stimulate root growth. Dip the cut end of the stem into the rooting hormone and gently tap off any excess. Then, insert the cutting into a small container filled with moist potting mix. Pat the soil around the cutting to ensure good soil-to-stem contact.
Warning: Hydrangea cuttings are susceptible to heat and direct sunlight, so it’s important to keep them in a shaded area with bright but indirect light. Placing a plastic bag or a clear plastic container over the cuttings can help create a greenhouse effect and retain moisture.
Within several weeks, the cuttings should start to grow roots. During this time, it’s important to keep the soil consistently moist but not soggy. Once the roots have developed and the plant has started to grow new leaves, it’s time to transplant it into a larger pot or into the garden.
When transplanting, choose a location with well-draining soil and plenty of morning sun. Dig a hole that is slightly larger than the root ball, and gently place the plant into the hole. Backfill with soil and water thoroughly to settle the soil around the roots.

How to Grow Hydrangeas From Stem Cuttings in Soil
Hydrangeas are beautiful flowering plants that can bring vibrant colors to any garden. One popular method of propagating hydrangeas is through stem cuttings. By following a few simple steps, even beginner gardeners can successfully grow hydrangeas from stem cuttings in soil.
Materials Needed:
- Pruners
- Rooting hormone
- Containers
- Well-draining soil mix
- Plastic bags or domes
Step 1: Choosing the Right Time
Hydrangea stem cuttings are best taken in spring or early summer when the plant is actively growing. Look for healthy, non-flowering stems and make sure to leave several pairs of leaves on each cutting.
Step 2: Taking the Cuttings
Using sharp, sanitized pruners, cut 4 to 6 inches long stems just below a set of leaf nodes. Remove any flowers or buds from the cutting, as they can drain energy from the plant and hinder root development.
Step 3: Preparing the Cuttings
Dip the bottom inch of each cutting into a rooting hormone to promote root development. Shake off any excess hormone and insert the cuttings into containers filled with well-draining soil mix. Firmly press the soil around the base of each cutting to hold it in place.
Step 4: Providing the Right Environment
To create a suitable environment for rooting, cover the containers with plastic bags or domes to increase humidity. Place the containers in a location with bright, indirect light. Avoid placing the cuttings in direct sunlight, as it can cause them to dry out quickly.
Step 5: Watering and Monitoring
Keep the soil consistently moist but not waterlogged. Water the cuttings thoroughly and frequently to ensure they remain well-hydrated. However, be careful not to overwater, as this can lead to root rot. Watch for any signs of wilting or leaf discoloration, as these may indicate that the cuttings need more or less water.
Step 6: Rooting and Transplanting
After several weeks, the cuttings should start sprouting new growth, indicating that they have rooted successfully. Once the roots are well-established, the cuttings can be transplanted to larger pots or directly into the garden. It’s important to harden off the cuttings gradually by exposing them to outdoor conditions before planting them in the garden.
By following these simple instructions, anyone can become a master at propagating hydrangeas from stem cuttings in soil. With a little patience and care, you can enjoy the beauty of these stunning plants in your own garden.
Warning
Before you start propagating hydrangeas from cuttings, there are a few things you should consider. Hydrangeas are generally easy to propagate, but the success rate can vary depending on the type of cutting you use and the conditions in which you care for them.
First, it’s important to note that hardwood cuttings are the most commonly used for hydrangea propagation. These are stem cuttings taken from mature, woody branches. You’ll need to wait until the hydrangea plant is dormant, usually in late winter or early spring, before taking the cuttings.
Once you have your hardwood cuttings, be prepared to put in some time and effort to help them root and grow. Hydrangeas can take a while to root, so you’ll need to have patience. It’s also essential to keep the cuttings in a greenhouse or a damp, shady area to encourage root development.
Keep in mind that not all cuttings will root successfully. Some may not develop roots at all, while others may develop weak or unhealthy roots. It’s always a good idea to take several cuttings to increase your chances of success.
When you’re ready to plant your hydrangea cuttings, make sure to prepare the soil properly. The soil should be well-draining and rich in organic matter. You can mix in some compost or aged manure to improve the soil’s fertility.
After planting the cuttings, it’s important to keep a close eye on them for any signs of wilting or disease. Hydrangeas are susceptible to a few common diseases, including powdery mildew and root rot. If you notice any issues, be sure to take action promptly to prevent the spread of disease.
As the cuttings start to root and grow, you may need to repot them into larger containers. Hydrangeas have a vigorous growth habit and can quickly outgrow their containers. Keep an eye on the size of the plant and repot it as needed to ensure healthy growth.
It’s worth noting that propagating hydrangeas from cuttings can be a bit of a hit-or-miss process. Some cuttings may root and thrive, while others may not yield any new growth. If you’re someone who enjoys experimenting with plants and is willing to put in the time and effort, propagating hydrangeas can be a rewarding experience. However, if you’re looking for a guaranteed way to get new hydrangea plants, you may want to consider other methods, such as seed-starting or purchasing potted hydrangeas.
Before starting this process, it’s always a good idea to ask someone who’s experienced in propagating hydrangeas or do some research to help you better understand the steps involved. This includes watching updated videos or reading updated articles to stay up-to-date on the best practices for hydrangea propagation. Happy propagating!
When to Grow Hydrangeas From Cuttings
If you’re wondering when to grow hydrangeas from cuttings, there are many factors to consider. Hydrangeas can be propagated from cuttings taken in the spring or early summer when the plants are actively growing. This is the best time to take softwood cuttings, as they are more likely to root and grow successfully.
Before you start propagating hydrangeas from cuttings, you will need to prepare the plants for the process. Make sure you have a clean and sharp pair of pruners or scissors to take the cuttings. Cut a stem that is at least 4 inches long, and make sure it has several nodes on it. Remove any flowers or buds from the stem, as these can take energy away from the rooting process.
Once you have your cuttings prepared, you will need to dip the cut end into a rooting hormone. This will help stimulate root formation and increase the chances of successful rooting. There are plenty of rooting hormones available on the market, so choose one that suits your needs.
Next, you will need to prepare the soil for your cuttings. Fill a pot or tray with a well-draining soil mix. Make sure the soil is damp but not soaking wet. You can also add perlite or vermiculite to the mix to improve drainage. Make sure you have plenty of pots or trays ready, as you may need to grow several cuttings at once.
Now it’s time to plant the cuttings. Gently insert the cut end of the stem into the soil, making sure it is standing upright. You can place several cuttings in one pot or tray, but make sure they are not overcrowded. Leave a few inches of space between each cutting to allow for airflow.
After planting the cuttings, you will need to keep them in a bright location but out of direct sunlight. A morning sun exposure is ideal for propagating hydrangeas from cuttings. You can also use a greenhouse or a propagating box to provide a controlled environment for the cuttings.
Water the cuttings regularly to keep the soil moist but not waterlogged. Check the soil frequently and make sure it doesn’t dry out completely. Signs of wilting or yellowing leaves may indicate that the cuttings need more water. Be careful not to overwater, as this can lead to root rot.
Within a few weeks, you should start seeing signs of sprouting from the cuttings. This is a good sign that the cuttings have rooted and are starting to grow. Once the root system has formed, you can remove the cuttings from the propagation tray and transplant them into individual pots.
Transplant the rooted cuttings into pots filled with a well-draining potting mix. Water them thoroughly after transplanting to help the roots establish. Place the pots in a bright location, but shield them from the hot afternoon sun. Keep the soil moist but not waterlogged, and continue to care for the young plants as they grow.
Propagating hydrangeas from cuttings can be a rewarding experience for gardeners and growers. By following these simple guidelines and taking care of the cuttings properly, you can grow new hydrangea plants in no time. Just remember to choose the right time to take the cuttings, prepare the cuttings and soil properly, and provide the right conditions for rooting and growth. With patience and dedication, you can enjoy a beautiful and blooming hydrangea garden year after year.
