Return to Top Cuttings can be taken at almost any time of the year when the plant is in growth, making hydrangeas relatively simple to reproduce, even for complete beginners. If obtained in the summer, hydrangea cuttings root in just a few weeks or so. Remove all but a few of the leaves at the shoot’s tip, then cut the shoot off at the first node of the stem. Make sure you use a sharp knife to make the first node cut so it is clean and even. The cutting should then be dipped in hormone rooting powder or liquid before being placed in a peat-and-sand combination with moderate bottom heat. Kits for little plant propagation are perfect for this. The cuttings must be maintained moist and well-watered, but you must keep an eye out for the development of mold or botrytis on any older or dead leaves. Once the cutting has taken root, transplant it into a 1-liter pot, where it will spend its first winter as a dormant plant in a cool greenhouse. Your plant will most likely be ready for planting out by the fall with one more potting on in the following summer.
1. Cutting a plant from the ground
Cut the side leaves off.
3. Trim the top off right before the first two outside leaves.
4. One pair of leaves and no stalk above should remain once the top has been removed.
5. Join the two leaves together and use scissors to snip off the tops of the leaves.
6. Before the subsequent joint, trim the remaining stalk below the leaves.
7. Apply rooting powder to the cutting.
8. Firmly press the cutting into the compost in the cell tray.
9. Your cutting should take root like this before being potted up or planted in the garden.
When should hydrangea cuttings be taken?
When new stems initially begin to harden, in late spring or early summer is the ideal time to propagate softwoods. This occurs in the majority of locations between May and mid-July. At this point, cuttings are prone to strong growth and new hydrangea stems bend yet snap off readily.
When are hydrangea cuttings available in the UK?
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.
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.
How long does it take for cuttings of hydrangeas to root?
- 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.
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.
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.
Can you grow hydrangeas with Miracle Grow?
There is no need to buy expensive plant food. This cost-effective alternative has a 15-30-15 N-P-K composition that encourages more flowers per shrub and colorful flower heads.

- Approximately 1.5 pounds
- encourages most flowers to bloom more
- Easily combines in a watering can
- increases some plants’ size
- Must be routinely administered and suitably diluted.
How are RHS hydrangea cuttings taken?
collecting cut materials
- When it is still full of water in the morning, gather your materials (turgid)
- Gather the non-flowering shoots since they will root easier.
- Up to 10 cm (4 in) of shoot should be removed, properly clipped off above a bud on the parent plant.
- Put the trimmings material in a labeled, clean plastic bag.
How fast do hydrangeas grow in the UK?
- Containerized plants should have regular moisture checks to prevent drying out. In the summer, move containers to a more shaded area to prevent drying out.
- If rainwater is scarce, water blue-flowered cultivars with tap water to minimize drought stress rather than rainwater to preserve the color of the flowers.
Feeding
After planting, use a general fertilizer like Vitax Q4, Growmore, or fish, blood, and bone.
Established plants typically don’t require regular feeding. Too much fertilizer promotes excessive soft, leafy growth, which makes plants more vulnerable to frost damage and less likely to produce flower buds.
A spring application of general fertilizer may be beneficial for struggling shrubs growing in lighter, sandier soils. Mulching may be more beneficial because this issue can also be brought on by drought stress.
- The wilted flowers don’t need to be taken out right away. The dead blooms can provide interest well into the winter and aid in preventing frost damage to the young, fragile foliage below.
- Wait until mid-spring to prune stems back to the first or second healthy, vigorous pair of buds below the faded bloom.
- Lacecaps can be deadheaded after flowering if desired, however mopheads should only be deadheaded in cooler climates.
pruning mature Hydrangea macrophylla and Hydrangea serrata lacecaps and mopheads
- Mid-spring is the time to prune.
- Lightly but frequently prune. Because flowers are created on new shoots that emerge from stems from the previous year, severe pruning will result in the loss of blossoms.
- To promote the growth of fresh, more floriferous replacement shoots, remove one or two of the oldest stems from the base.
- Cut off all the stems at the base of overgrown or neglected bushes to renovate them. The following year will be the first time the new stems bloom.
- Prior to the shrubs’ vigorous growth in the spring, prune
- Although annual pruning of last year’s growth stimulates more abundant and larger flowers, regular pruning is not necessary.
- Create a low framework of woody branches by pruning the growth from the previous year to the lowest pair of sound buds. Typically, this yields a pruned framework no taller than 25 cm (10 in); but, if additional height is needed, cut to around 60 cm (2 ft) tall.
- Usually, neglected plants react well to more severe pruning to rebuild the low framework.
There are also other varieties of hydrangeas, such as Hydrangea aspera, Hydrangea aspera Villosa Group, Hydrangea quercifolia, and Hydrangea sargentiana.
- trim in the spring
- To get rid of dead and excessively long stems, just minor pruning is required.
Cuttings make for simple propagation. It will take the plants two to three years before they begin to bloom.
Take softwood cuttings in the late spring through the middle of the summer, semi-ripe cuttings in the middle of the summer, and/or hardwood cuttings in the winter.
