Early in the day, before the heat and sun of the day begin, is when plants are most refreshed and hydrated. These shrubs require moisture to survive. Cuttings of hydrangea collected in the early morning have a significant advantage over cuttings from hot, dried-out stems.
Pick a fresh stem from the growth of the current year. Compared to older stems, it will have a lighter hue. Select a stem with many of leaves that is non-flowering for the greatest results. You can take several cuttings from different stems or use one stem for many.
Using a knife or pruning shears, cut the stem into 4- to 6-inch sections. Each piece should be cut just above the node where the stem and leaves meet. New roots will grow from these nodes. Every leaf but the one put at the top of each cutting should be removed. Then, keep the cuttings moist as you work by submerging them in shallow, warm water.
Can a hydrangea be started from a cutting?
Take a 5- to 6-inch-long clipping off a limb of the hydrangea shrub. According to the majority of experts, the cutting will thrive if it is taken from a branch that did not bloom this year.
Insert cuttings into moist vermiculite, coarse sand, or another sterile media after dipping them in rooting hormone (this step is entirely optional).
Well-watered pot should be allowed to drain. Make sure the ground is damp but not drenched. Plastic wrap the pot and the cuttings. Add stakes (#5) to try to prevent plastic from coming into contact with the foliage.
See several shortcut techniques that website visitors have sent me below. Okay, I’ll admit it—I tacked three steps onto step 5, but this is actually quite easy.
TIP: Position cuttings in direct sunlight. Never expose fresh cuts to the sun. They’ll be heated in the plastic. They should be kept in a bright, shaded area even if they are not in plastic.
Wait to water again until the soil’s surface feels a little bit dry. Cuttings will decay if they receive too much water.
In 2-3 weeks, depending on temperature (faster in warm weather) and humidity, cuttings should start to grow roots. Some cuttings take as little as a week to take root. When a cutting is pulled and the pull is resisted, it is rooted.
Note on overwintering Cuttings
The most challenging aspect of establishing fresh hydrangeas from cuttings is getting them through the first winter without a greenhouse. To offer new cuttings the best chance of surviving the winter, start them early in the summer.
While some people are able to take cuttings indoors throughout the winter, this generally is not a good idea. Outdoor cultivation of hydrangeas is ideal. Two ideas for preserving cuttings during the winter are as follows:
(1) Plant cutting pots in the ground and cover them thoroughly with thin mulch.
(2) Next to a foundation, place smaller pots of cuttings that will be covered by huge clay pots for the winter.
When should hydrangea cuttings be taken?
Late July is the ideal time to take hydrangea cuttings. These cuttings are semi-ripe, which indicates that they come from the growth of the current season, yet they are old enough to have a woody base but are still soft at the tip. When the cuttings are added to compost, the woody foundation keeps them from decomposing.
How to take hydrangea cuttings
Use secateurs to gather material from the hydrangea stems and a knife to trim each cutting when taking hydrangea cuttings. You must place hydrangea cuttings into a pot of grittier compost because water cannot be used to proliferate them due to their woody nature. To keep your cuttings moist until the roots have formed, keep them in a propagator (usually after about six weeks). Winter in a frigid frame or anything comparable. Then, plant the cuttings when they begin to grow in the spring.
How can I bring a cutting of hydrangea inside?
Using a knife or secateurs, trim immature shoots from the plant to around 7.5cm (3in) long, right below the leaf joint.
To assist prevent water loss and wilting, remove the lower leaves from the stem and, if the top leaves are huge, cut them in half.
Perlite or sharp sand and multipurpose compost can be combined 50:50 to create the rooting mix. It drains effectively and holds moisture.
Put the cuttings in cell trays or around a small pot of compost, water them, and keep them moist and out of the sun.

Can hydrangea cuttings be rooted in water?
I am kind of thrilled to try out water propagation on the other plants as it has just been quite popular online (I’ll keep sharing the findings from the items we propagate as soon as I figure out what they are all!). However, some of the information I’ve read suggests that water propagation is not recommended for hydrangeas in particular since it results in a weaker root system, which makes them more likely to fail when you transplant them to soil.
Since I haven’t used it personally yet, I’ll also remark that a reader previously commented in a post that she hasn’t encountered any issues. So please let me know if you attempt it this way and are successful!
The other plants can be propagated in water quite easily:
- Grab a little plant cutting.
- Place it in a glass so that the stem is submerged in the liquid but that the leaves and other components are not (otherwise they would rot).
- Use a transparent glass so you may more easily track the root’s development.
- Water should be replaced every several days.
- Set up in a location with enough natural light (we’re using the bedroom windowsills because they have wonderful, filtered light from the window film).
How much time does a hydrangea cutting take to take root?
Put your covered cuttings in a cozy spot with some light coming from the side. Avoid direct sunlight at this vulnerable stage. To keep the potting mix moist but not soggy, water it as needed. To prevent dehydration and maintain a high humidity level in your miniature greenhouses, mist your cuttings frequently.
Temperature, humidity, and the condition of your parent plant are a few of the variables that affect how long it takes for your plant to root.
1 But the majority of softwood hydrangea cuttings should begin to root in two to four weeks. Pull on a cutting really gently to gauge your progress. You’ll encounter a little resistance from the fresh, sensitive roots. You’ll also notice new leaf growth soon.
Celebrate the success of your propagation after your new hydrangeas are well-established and have robust, healthy new growth. As the following step toward the garden, transplant your creations into larger containers or send them on to their new residences.
How might cuttings’ roots be encouraged to grow?
Even if you already know how to root a plant in water, David Clark, a professional gardener, has some excellent advice that will help you make the procedure more effective.
He offers advice on two simple plant-starting techniques that you might not have known about.
Two practical workshops on plant propagation were recently presented by Clark at the Buffalo and Erie County Botanical Gardens.
He provided a plethora of knowledge, including these five excellent suggestions:
1. Build a miniature greenhouse. How frequently have you purchased comforters or bedding that was packaged in a plastic zipper bag? I frequently do so, and I usually consider, “This bag ought to be useful for something.
According to Clark, these bags make excellent miniature greenhouses for newly transplanted or rooted plants. Simply place the plant inside the bag and partially zip it up. This will assist in retaining moisture. In addition, a small aperture permits airflow to stop the development of mold.
“Because the plant needs to be confined, unless you have a greenhouse, Clark explained, I almost always root with a bag.
The bedding bags, as shown in the picture at the top of the article, can hold either a sizable plant or a number of smaller plants.
2. Use powders for rooting. By soaking a plant cutting in water, you can multiply plants in one of the easiest ways possible. Trim the stem horizontally above a node (see photo above). Soft, fleshy plants like the Wandering Jew, ivy, arrowhead plant, and spider plant respond nicely to this technique.
Using rooting products will boost your chances of success, according to Clark. There are numerous commercial goods available. These products contain a growth hormone to hasten the emergence of roots and destroy bacteria and fungi to stop the stem from decaying.
Dip your stem into the powder after dispensing a tiny bit of it. (Avoid inserting the stem into the product container directly.) Give the stem a minute to settle. The powder will be absorbed by the plant. Put the cutting’s tip in water; the water won’t completely wash the powder away.
He added that you can also utilize common home items to speed up roots. Cinnamon can be used to eliminate fungus and bacteria on plant stems. Make a rooting solution by dissolving one aspirin in water to encourage the formation of roots.
3. Give your new plant enough time to adjust to soil after being in water. According to Clark, if you root your cutting in water, it will grow roots that are best adapted to obtain its nutrients from water as opposed to soil. The plant could become stressed if it is transferred from water to soil right away.
As an alternative, mix a little dirt into the water you’re using to root your cutting. Do this gradually over the course of four or five weeks to allow your plant adjust to its new growing environment.
4. Learn about leaf section division. You may grow new plants from the leaves of succulents like the sansevieria pictured above. It’s not even necessary to utilize the full leaf; only a portion will do!
When you cut the leaf, Clark advised, be sure to mark which portion is the top and which is the bottom. As shown in the leftmost photo below, place the bottom portion of the leaf segment into a tray of moist perlite. (Fun fact: Perlite is a byproduct of volcanoes.)
5. Encourage plant runners as a means of division.
View the image of the Wandering Jew that is located close to the beginning of this article. Burying the stem horizontally is another approach to multiply such a plant. These nodes will produce new plants.

How long does it take hydrangea cuttings to bloom?
Roots should have completed root formation after four to eight weeks. You can either plant your new hydrangea in the garden or transfer it to a bigger, more durable pot.
For the first several weeks following planting, water thoroughly. Our guide has further information on how to grow and take care of hydrangeas.
Putting plants in a greenhouse or burying pots in the ground and covering them with a heavy layer of mulch will safeguard them till spring if they are not strong enough to be planted before winter.
When do hydrangeas bloom?
The type, cultivar, planting zone, and hydrangea blooming season all affect when they bloom. The majority of hydrangeas with new growth form buds in the early summer in preparation for blooming the next spring, summer, and early fall. Hydrangeas may stop flowering in the heat of the summer in hot locations, but they will blossom again in the fall.
How do you cut back hydrangeas?
Hydrangea plants don’t require pruning if they are allowed plenty of room to develop in the garden. Only the periodic clearance of dead wood is necessary.
Do you need to deadhead hydrangeas?
Your hydrangeas will continue to bloom into the fall if you deadhead them. Hydrangeas make wonderful cut flowers, so there’s no need to wait until the flower wilts. Leave the early fall blossoms alone so they can fade naturally. In the days leading up to your freeze date, you don’t want to promote new growth.
How do you control hydrangea color?
The distinction of hydrangeas is that you can modify their color. But keep in mind that not all hydrangea varieties can change their color. H. macrophylla, a species of bigleaf hydrangea, responds to changes in soil pH. Hydrangeas can absorb aluminum thanks to a low soil pH, which gives the blossoms a lovely blue hue. Reduce the pH of your soil by mixing in sulfur or peat moss to enhance the number of blue hydrangea flowers. Throughout the growth season, you can keep amending your soil with extra aluminum sulfate. When you add ground limestone to boost the pH, pink and red blooms shine.
You may precisely modify your hydrangea color using a soil pH test. To avoid the plant from being harmed, keep the pH level below 7.5. In the fall, all hydrangeas will naturally fade regardless of the modifications you’ve made. Don’t worry, the plant will display vibrant, new blossoms once more in the spring.
Can hydrangeas grow in shade?
Although they won’t blossom in complete shade, hydrangeas prefer dappled or infrequent shade. How much sun do hydrangeas need is more important to consider than whether they love the sun or the shade. Your hydrangeas require more sunlight the further north in your garden you are. A general guideline is six hours of sunlight each day. However, southern hydrangeas can thrive with just three hours of sunlight per day.
Can hydrangeas grow in full sun?
While hydrangeas prefer morning sun, they struggle in the hot, afternoon sun. For these gorgeous creatures, partial shade in the later hours of the day is optimal.
Can you grow hydrangeas in pots?
Even if you don’t have enough room in your garden to cultivate hydrangeas, you can still enjoy these lovely blossoms by learning how to grow hydrangea in a pot. As long as you follow the fundamentals of caring for hydrangeas, the procedure is rather straightforward. Select a pot with at least an 18-inch diameter to accommodate the mature size of the particular hydrangea you are growing. In order to maintain the constant moisture level that hydrangeas demand, look for non-porous containers. Excess water will be able to adequately drain thanks to drainage holes. Consider growing dwarf hydrangeas like Buttons ‘n Bows, Mini Penny, and Little Lime.
How do you keep hydrangeas from wilting?
Morning irrigation on a regular basis can assist stop withering. Some hydrangea cultivars simply can’t stand the heat. No matter how much water you give them, they will begin to wilt in the afternoon heat. Mulch applied in layers can help soil retain moisture and stay cool. You shouldn’t be concerned if your hydrangeas bloom again once the day cools. A little midday wilting is preferable to overwatering and drowning your hydrangeas.
