Hydrangea is a genus of flowering plants in the family Hydrangeaceae, native to woodland, thickets and swamps in temperate and subtropical regions of the world. There are over 100 species of hydrangea and they grow best in acidic soil that is moist but well-drained.
How To Propagate Hydrangea
Here is the complete process explained in detail on how to propagate hydrangea:
1. Select a healthy plant.
Look for a healthy, vigorous plant that has several buds on it. It should be at least 2 years old, but older is better.
The best time to propagate hydrangea is in the late fall or early winter when the new growth has hardened off and there are no leaves on the plants. The buds will be dormant during this time of year, so you won’t have to worry about them being damaged by the process.
2. Prepare to take cuttings from your hydrangea shrub.
Since you’ll be taking several cuttings at once, it’s important that they all have similar growing conditions so they’ll grow into similar plants after they’ve been transplanted into their own containers or beds in your garden.
Choose only one variety of hydrangea to work with at a time so you can keep track of which ones came from which parent plant if you want to try different varieties later on (or if you’re interested in breeding your own unique varieties). Make sure the area where you’re working is well lit and that the soil is moist but not wet (wet soil can cause rot).
3. Cut back the stem of your hydrangea shrub just below a leaf node .
A leaf node is where one or more leaves emerge from a stem; it’s where new growth begins, so cutting back just below one ensures that all of your cuttings will have plenty of new growth for root development once they’ve been planted in their own pots or beds in your garden (and it makes them easier to handle). Use clean pruning shears and make sure there are no leaves left on any stems before proceeding with step 4 below.
Step 4:
4. Remove any foliage from around the bottom 6 inches of each cutting . This will ensure that enough energy goes into producing roots instead of foliage, since these cuttings are destined for their own individual pots where they’ll receive plenty of sun once they’re planted outside (and won’t need as much foliage). If there are any flowers on the stems, remove them as well; leave only bare stems behind when you’re done with this step.
5. Dip each cutting in rooting hormone powder .
Then stick each cutting directly into its own pot filled with moistened potting soil . This step isn’t necessary if you plan on planting these cuttings directly into flower beds outdoors instead of keeping them in pots first; however,
it’s still recommended because it gives each cutting an extra boost during its initial root development period and helps prevent transplant shock when you move them outdoors after their roots have become established inside their pots/beds (which is exactly what happened here ). You can buy rooting hormone powder at most nurseries and big-box stores; just make sure it’s labeled “for use on flowers.”
Step 6:
6. Water thoroughly until water drains out through drainage holes . This step isn’t necessary if you plan on planting these cuttings directly into flower beds outdoors instead of keeping them in pots first;

Step 7:
7. Place each pot inside a clear plastic bag , then place those bags inside another bag filled with peat moss . This step isn’t necessary if you plan on planting these cuttings directly into flower beds outdoors instead of keeping them in pots first; however, it’s still recommended because it helps hold moisture around each cutting while protecting against frost damage until warmer weather arrives outside (and prevents bacteria buildup due to excess moisture/watering issues).
Step 8:
8. Seal up both bags completely , then store somewhere warm until spring . If possible, store these bags indoors near a sunny window where temperatures remain above 45 degrees F during cold winter months – otherwise, store them outside under cover but still close enough to remain above freezing temperatures throughout winter months (you may need to bring inside briefly whenever temperatures drop below freezing overnight).
If storing outside , keep bags away from any potential sources for heat like fireplaces or woodstoves – both will dry out surrounding air too much around stored bags – plus don’t seal up bags too tightly ; allow some air circulation around stored plants while they’re resting over winter months so they don’t get too dried out over time while waiting for warmer weather to return outside next spring.)
Step 9:
9. Transplant newly rooted rose clippings back into your garden once spring arrives . Keep newly transplanted rose clippings indoors until nighttime temperatures consistently remain above 55 degrees F before moving back outdoors – this could take anywhere from 1 week to 2+ weeks depending upon how warm things get during late spring
Tips for How To Propagate Hydrangea
Here are 5 things to take care of with respect to how to propagate hydrangea:
1. You can use a sharp knife and cut the hydrangea’s stems. Make sure you cut them at least five inches from the ground.
2. After cutting, place the stem in water for about three to four weeks before planting it in your garden.
3. When you are ready to plant it, make sure that you dig a hole that is deep enough for the entire stem of the hydrangea to be buried under ground level.
4. After planting, cover up your hydrangea with soil and water it well so that it gets established quickly!
5. If you want more hydrangeas, just repeat steps 1-4!
Interesting Facts About Hydrangea
Here are 5 things you should know about hydrangea:
1. Hydrangea is a genus of 70 species of flowering plants in the family Hydrangeaceae, native to woodland and thickets from southeastern Europe to Japan, with the highest species diversity in China and Japan.
2. The name hydrangea derives from the Greek words ὑδραγός (hydra) meaning “water” and γοῦνος (gounos) meaning “wine” or “vinegar”, possibly referring to the color of some hydrangeas which may turn red in acid soil.
3. The most common hydrangea species are H. arborescens (the bigleaf hydrangea), H. paniculata (the panicle hydrangea), H. quercifolia (oakleaf hydrangea), and H. serrata (Japanese hydrangea).
4. The leaves are opposite, simple ovate-acuminate, 2–6 cm long and 1–3 cm broad at the base; they are arranged spirally on the stems, but with successive leaves often twisted at the base so that they appear whorled when viewed from above. In most species, leaf edges are serrated or lobed; leaf veins arise at angles from the leaf margin in a pinnate pattern characteristic of the family Hydrangeaceae; this is called pinnate venation or pinnation.
5. There are about 30-40 species of hydrangeas found across North America including: oakleaf hydrangea – Hylotelephium telephium; smooth hydrangea – Hylotelephium spectabile; Japanese hyrdangaie – Hydrangeae macrophylla variegata; large flowered hyrdangaie – Hydrangeae macrophylla flore pleno and mountain hyrdangaie – Hydrangeae montana variegata
FAQs
I have a hydrangea that I want to bring indoors for the winter. I want to root it in water before moving it.
Can you do this?
Yes, you can root hydrangeas in water. It is actually a very easy process for most varieties and is one of the easiest ways to propagate hydrangeas. The best time to take cuttings is late summer or early fall when the plant has gone dormant and there are no leaves on the branches. Use a sharp knife or pruning shears to make your cuttings at least 4 inches long and remove any flower buds from them. Dip the ends of each cutting into rooting hormone, then insert the cuttings into a jar filled with pure water or a potting mix that drains well (usually half perlite and half peat moss). Place the jar in bright but indirect light and keep it moist until roots appear, which should be within 2-4 weeks depending on temperature. Once rooted, you can transplant your new plants into pots or directly into the ground outside where they will grow happily for many years!
How to grow hydrangeas from stem cuttings?
Hydrangea paniculata, the most common species of hydrangea in the United States, is a large shrub that produces white and blue flowers. It can be grown as a hedge or trained on an arbor. It will also make a good specimen plant for the garden. The plant is native to Japan, but has been cultivated for hundreds of years in China and Korea.
Hydrangeas are deciduous shrubs with opposite leaves that are usually serrated along the edge. The flowers are usually large and showy and come in many colors including pink, purple, blue, red and white. Hydrangeas can be used as foundation plants or they can be trained on an arbor or other structure such as a pergola or gazebo. They will also make a good specimen plant for the front of your garden.
The most popular types of hydrangeas used for landscaping purposes include: H. macrophylla (big leaf), H macrophylla ‘Annabelle’, H macrophylla ‘Snow Queen’ (white), H macrophylla ‘Endless Summer’ (pink), H paniculata ‘Limelight’ (pink) and H paniculata ‘Grandiflora’
Hydrangeas are propagated from softwood tip cuttings taken in the early spring. The best time to take softwood cuttings is from mid-March through mid-April. Cuttings should be 6 inches long and have at least two sets of true leaves. Dip the cut end of each cutting in rooting hormone, then place them in a shallow container of water until they are ready to be planted. Plant the rooted cuttings in a light, well-drained potting soil mixture and keep them moist but not soggy. Place the pots in bright indirect sunlight for about two weeks to harden off before transplanting outdoors.
How do you care for hydrangeas?
After planting your new hydrangea plant, water it thoroughly and keep the soil evenly moist throughout the growing season. During hot dry periods, you may need to water your hydrangea twice a week or more depending on its size and location. To help prevent disease problems with your hydrangea, avoid overhead watering as much as possible and remove any diseased or dead branches promptly. Pruning is necessary only when needed to maintain shape or size; otherwise leave it alone!
Rooting time depends on the species of hydrangea. Some take as little as one month, while others take up to six months. The most common time for rooting is about two months.
How do I choose a good cutting?
Choose a stem that has at least three sets of leaves and is not too thin or too thick. Cuttings should be anywhere from 4 to 6 inches long, with the thickness being dependent on the size of the plant you are propagating. You can also take a cutting from a branch that has already bloomed, but it will take longer to root. Make sure your cutting has several nodes along its length and that each node contains at least one leaf. If you’re taking cuttings from a shrub or tree, make sure they are at least 6 inches long, otherwise they may not have enough leaves or nodes for rooting to occur properly. To ensure success, never take more than 25 percent of a plant’s foliage in any given season.
How do I prepare my hydrangeas for rooting?
Remove all large leaves from your stems before planting them in water (see below). Do not remove leaves from branches with small buds because these buds need to stay intact until after rooting occurs so the new plant can begin growing immediately upon transplanting into soil. Never remove flowers from your plants because this will slow down growth and delay flowering next year.
