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.
When should hydrangea cuttings be taken?
There are several widely grown hydrangea species, each with slightly distinct requirements and growth traits:
- Big leaf hydrangeas, or Hydrangeamacrophylla, are hardy in USDA zones 5 to 11. They grow 6 to 10 feet tall and have flowers in shades of blue, pink, and white. This kind seems to be more tolerant of indoor cultivation, therefore some growers think early fall is the best time to take cuttings from it. However, spring cuttings also seem to function well.
- Smooth hydrangeas, or Hydrangea arborescens, are hardy in zones 3 to 9 and grow 3 to 5 feet tall with white flowers. Although stem cuttings can also be used, root cuttings are frequently used to produce this species.
- Oakleaf hydrangea, Hydrangea quercifolia, grows to a height of about 8 feet and has white blossoms. It is hardy in zones 5 to 9. Early in the spring, take cuttings from stems that aren’t blooming, then root them in a pot until a strong root system has formed.
- Tree hydrangea, often known as the panicle hydrangea This cultivar is hardy in zones 3 to 8, growing 8 to 15 feet tall with white to pink blooms. In order to grow fresh garden plants for the fall, these are also best rooted in the spring.
To be sure you comprehend the requirements of the new plants you are developing, it is advisable to do some research on the numerous varieties of hydrangea. Be aware that each species has a variety of cultivars, each with distinct qualities of its own.
Can hydrangeas be divided in half and planted again?
Once your plant has been divided, you must treat each half as you would any transplant. Get them as soon as you can back into the soil. The ideal situation would be to already have a hole prepared in the new place.
Before replanting, water the area and loosen the soil a little to make it easier for the roots to take. Use the soil markings on the stems as a guide to ensure that you don’t plant your hydrangea any deeper in the ground than you did before.
Spreading mulch around the base will protect the roots from the sun and prevent weed growth. For at least a month, give the transplants plenty of water to promote strong root development.
Keep in mind that the first season following hydrangea splitting may not see blooming. They won’t have time since they’ll be too busy developing their root systems and healing from the strain of being transplanted. Your hydrangeas should recover to their typical magnificent selves after a season of recovery.
How should a hydrangea cutting be rooted?
- 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.
- The bottom two leaf nodes’ lower leaves should be removed. A leaf emerges from the branch at the leaf node. At that time, the majority of roots will form.
- Reduce the largest leaves’ size by around 50%.
- Insert cuttings into damp vermiculite or sterile medium after dipping them in rooting hormone (this step is absolutely 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. Use stakes to try to prevent plastic from coming in contact with the foliage.
TIP: Position cuttings in a well-lit, shaded area. Never expose fresh cuts to the sun. They’ll be heated in the plastic.
Wait to water again until the soil’s surface feels 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. Reminder: It might not be allowed to reproduce plants that have been trademarked or registered.
I adore this simple approach. If you don’t have a lot of hydrangeas, you are only able to root a small number of new plants at once.
When you gently bend a branch down, the area where it will contact the ground has roughly 5 to 6 inches of leaves removed from it. In this location, remove a small amount of bark from the branch’s underside. Ascertain that at least one leaf node will be below the surface.
Don’t remove the branch from the parent plant. Lower the branch into a small trench that is approximately 2 inches deep and generously top it with soil. Put a block or stone on the area that will be buried to ensure that it stays there. Additionally, this aids in keeping the moisture surrounding the branch. Keep it occasionally watered. When the branch from the mother plant develops roots, break it off and plant it in a pot or the garden.
Hydrangeas like humid, partially sunny weather. On the north and east sides of your house, they work well.
Can a hydrangea be started from a cutting?
Although hydrangeas are often mistaken for perpetual flowers, they are actually woody-stemmed shrubs that have a different root system than non-woody, soft-stemmed plants. Because of this, trying to root hydrangeas in water, as you might with certain houseplants, rarely works. For best results, plant hydrangea cuttings at the right time in potting soil.
Like growing roses, there are different ways to grow hydrangeas. When the year’s new stems have grown solid and robust, in late fall or early winter, “hardwood” cuttings obtained from hydrangeas can be rooted. However, it takes a long time for hardwood cuttings to root. 1 The majority of hydrangea producers in the industry employ “softwood” cuttings because they root more quickly and produce superior results.
Can hydrangea cuttings be rooted in water?
Rooting hydrangeas is not too difficult. While some people have succeeded in rooting them in water, many others (like myself) have never been able to do so.
The image to the right, which Susan Park Cole forwarded to us, shows how hydrangeas can be rooted in water. On sometimes, roots appear when an arrangement is left in water for a prolonged period of time. But in my experience, this approach more frequently fails than succeeds.
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.
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.
Do hydrangeas need to be pruned back before being transplanted?
The root-pruning of hydrangeas is frequently advised by horticulturists a few days before transplanting.
I grow a lot of hydrangeas. A small strip of land between my driveway and the house next door is where two of them, each about 4 years old, are growing. I have to regularly prune them away from the driveway because they are becoming fairly tall. They should be relocated, please. Is it feasible to move the hydrangeas without harming them, and if so, what would be the best course of action? Euclid’s Abbie Vernon.
Hydrangea transplanting is risk-free if you follow the correct procedures. Losing the plant is always a possibility, though.
The fall, after the plant has lost its leaves and gone dormant, is the finest time to transplant hydrangeas. Ideal conditions include cloudy days with cool temperatures above freezing for at least a few weeks.
The plant should be root-pruned a few days before being transplanted, according to many horticulturists. This lessens the shock to the plant. Dig a 45-degree angled, shovel-deep ring just beyond the plant’s leaf line with a spading shovel. With as little disruption to the roots as possible, only make one cut. The following few days, make sure to give the plant enough of water so the roots can rest.
If the plants are quite huge, you can trim the stems by one-third, but if the variety blooms on old wood, you will lose your blooms the next year. One to two years may be needed for larger plants to recuperate from transplanting. Newer cultivars, such the “Endless Summer” hydrangea, bloom on fresh wood, lowering the likelihood that you won’t have any flowers the following year.
Prepare your hydrangea’s new home before removing it from its present place. Dig your hole with particular focus on width. Don’t squeeze the root ball; instead, leave it room so that roots can spread out naturally. Work some quality planting soil, such Fafard Planting Mix, into the existing soil. Whenever you are planting or transplanting any landscaping plants, I also advise using Espoma’s Bio-Tone. Bio-Tone will assist lessen transplant stress and hasten the establishment of the plant’s roots.
You can start transplanting your hydrangea after the new hole has been made. Take care not to harm the roots as you use a spading shovel to gently rock the plant out of the ground. Never touch the plant or move it by the branches; always move it by the root ball. To lessen the possibility of injuring the plant before pulling it out of the ground, some gardeners prefer to delicately tie the plant’s branches using burlap and rope.
Once the plant is loose, rapidly move it to its new position by loading it into a wheelbarrow or tarp. Place the plant in its new location at the same depth that it was previously planted at, backfill the hole with a combination of new planting mix and existing soil, ensuring that there are no gaps, water well, and mulch. Mulch will assist keep the soil moist, the weeds out, and the roots of the plant cool.
Never allow the roots to become dry; water your hydrangea regularly until winter; however, take care not to overwater as root rot could result.
The next summer, when you notice the plant growing once more, fertilize your hydrangea. Good fortune!

What is the ideal location to plant hydrangeas?
Plant hydrangeas close to a water source in an area with lots of light. Choose a location in the South where there is morning sun and afternoon shade. Hydrangeas can tolerate full-day sun in the north.
How might cuttings’ roots be encouraged to grow?
Hello! Thank you for coming! I’m going to demonstrate how to root plant cuttings in water for you today. This is a fantastic approach to increase the number of your plants and spread your love of plants to friends. I will admit that it can be challenging to give away a plant that you have nurtured from the very beginning. But seeing improvements is so exciting and satisfying! I recently donated two cuttings of Chain of Hearts to households that are really fantastic. I’m eager to follow their development.
I used to work at a golf course with a 30 foot Monstera deliciosa when I was in my early 20s. 30 feet—you read that right! I developed a liking for flora because of that. If you didn’t already know, it’s actually my all-time favorite plant. Regardless, some of the leaves were 2 feet broad and breathtaking! One day, I noticed a tiny leaf emerge from the ground, and when no one was watching, I removed the dirt from the stem’s bright green color and pulled the leaf out. I kept checking behind me as if I were ready to commit a bank heist or something. Actually, I suppose that it was theft. But that’s not how I saw it. I was sharing the good vibes! But let’s be really clear: IF YOU DO IT AT A STORE, IT IS STEALING, so don’t do that! My supervisor finally heard me out (it was weighing heavily on my conscience), and he laughed, called me silly, and said it was absolutely fine! All of this to say, I brought it home, planted it in water, and it grew, making me very pleased! I was in awe of this incredible replication technique. Let’s discuss how to water-root plant cuttings.
The majority of common house plants can be propagated using water. Currently, I’m focusing on a tiny little stem from my large Fiddle Leaf Fig. There are no roots yet, but there is a small leaf of green!! Try it if you’re not sure.
Let’s get started
- Choose the spot on the main plant where you will cut your cutting. Finding the root node on your plant is important since not all cuttings that will root in water have them, but the majority of them do.
- Make a clean, precise cut immediately below the node with a knife or pair of scissors. 1/4 or so below the node.
- Set the cutting inside a spotless glass. Pour enough room-temperature water over the cutting nodes to cover them.
- Every 3-5 days, replace the water with brand-new, room-temperature water.
- Keep an eye on your roots as they expand! Depending on the plant, this could take weeks or even months.
- When your roots are around 3-5 inches long, it’s time to plant the cutting in soil!

Your rooted plants should be placed in a location with strong indirect light. Additionally, you’ll need patience—serious patience! It’s not necessarily bad news if you are attempting a fresh cutting and two weeks pass without any roots. Someone I know submerged a fiddle leaf fig leaf in water, and three months later, she noticed roots.
Make careful to clean and lightly rub the roots with your fingertips after changing the water. Before putting the roots in the fresh water, you should wipe off any mucky film (that’s the precise phrase).
You only have to do that! It’s really easy. You can now create your own plants and exchange them with pals. It’s one of my favorite activities. Check out my post on How to Repot a Houseplant when you’re ready to pot your rooted plant. Even though you won’t be repotting, there are some useful suggestions for potting in general. Many thanks for stopping by! See you again soon!
