A hydrangea’s roots shoot can be cut off from the mother plant and planted somewhere to produce a new (and free) hydrangea.
Q: In front of my house, there is a really enormous hydrangea. It receives morning sun and is flourishing. I want to split it in half and move a piece of it to another area of my yard. Can you divide hydrangeas? If so, when would be the ideal time to do it? Do they thrive in the shade?
A: Hydrangeas are an exception to the rule that not many shrubs may be divided like perennial flowers, and they are probably one of the simplest to “create kids” this way. Comparable to splitting a perennial flower, the procedure.
The greatest option is to search for shoots that are poking through the plant’s outermost layer. These shoots typically have their own healthy underground root system at their base a year or two after they first appear.
Sever the stalk with a spade to check for a piece with roots. If you succeed, you will have a young plant that is prepared for replanting.
This type of viable perimeter shoot is common on mature hydrangeas, and it can be dug up and divided. It’s the major method by which hydrangeas increase their range.
Whole hydrangea plants can be pulled up and divided into two or more parts if you don’t notice any shoots or are obtaining portions with no roots.
Look for naturally occurring divisions in the root ball, such as intersections where the main stems are protruding. A wishbone from a turkey can sometimes be separated by simply pulling apart the parts. To divide the plant, you could occasionally require a fork or a shovel.
In either case, you now have two plants to replant once you have two sections with roots connected to each.
Early spring is the ideal time to divide bigleaf hydrangeas, when the stems’ fresh green buds are just beginning to swell and unfold. A few while ago, that was. Mid to late October is an excellent period as well.
Treat divisions like a fresh plant by keeping them continually wet. These divisions’ smaller, weaker roots can’t draw as much moisture from the soil as a mature hydrangea’s large, well-established root system.
Your hydrangea’s placement in the early-morning sun is ideal. The majority of hydrangea varieties thrive in rich, moist soil with good drainage that receives early and afternoon shade.
Although they will live in heavy shade, they might not bloom at all or only slightly. Choose the native smooth hydrangeas, botanically known as Hydrangea arborescens, for heavy shade.
By the way, another question I’ve been getting lately is how hydrangeas will fair after many of their new leaves were destroyed by the almost record-breaking cold weather we experienced the third week of April.
Only the young leaves sustained the harm that I saw. In June, I predict that fresh leaves will emerge and the flower buds will unfold gracefully.
The flower buds weren’t developed enough, in my opinion, for the late cold blast to cause them significant harm.

How soon can I move? Hydrangeas named Annabelle
The pinkish-white blooms of the Annabelle hydrangea (Hydrangea arborescens), which bloom in the early summer, are some of the largest flowers of any hydrangea variety. When fully grown, an anabelle hydrangea typically grows to a height of 3 to 5 feet. The strong shrub known as Annabelle hydrangea, often known as “wild hydrangea,” takes transplanting well. November or December, after the first frost but before the ground freezes solidly, is the best time to transplant.
If the ground isn’t already wet, water your Annabelle hydrangea two to three days before transplanting.
The area where you want to relocate the Annabelle hydrangea should be prepared beforehand. Remove any rocks, huge clods, and weeds from the soil after working it for 15 to 18 inches. Select a location with well-drained soil where the Annabelle hydrangea will receive at least six hours of direct sunlight each day.

- The strong shrub known as Annabelle hydrangea, often known as “wild hydrangea,” takes transplanting well.
Only dig a hole that is two to three times as big and as deep as the root ball of the Annabelle hydrangea. When planting, the size of the hole can be changed, but it’s crucial to plant the Annabelle hydrangea as soon as you can.
The Annabelle hydrangea should be taken out of the ground. To preserve as much of the root system as possible, dig safely away from the tree using a shovel with a straight edge. The root ball will typically be 12 inches wide for every inch of trunk diameter as a general rule. Dig between 14 and 24 inches deep to reach the main roots of the bush.
Transfer the Annabelle hydrangea to a sheet of plastic. Drag it to the planting location if it is close by, then plant it right away. If the Annabelle hydrangea needs to be moved, wrap the root ball in wet burlap or peat moss and keep it out of the wind, direct sunshine, and extreme temperatures. The hydrangea’s root system should never be let to dry out.

- When planting, the size of the hole can be changed, but it’s crucial to plant the Annabelle hydrangea as soon as you can.
In the center of the hole, plant the Annabelle hydrangea. As the place where the trunk and root system meet, the crown should be about an inch above the ground.
Fill the hole with the reserved soil until it is halfway full, firmly pack the earth around the roots, and then add water. After letting the water drain, complete the soil placement in the hole.
Around the base of the Annabelle hydrangea, scatter 2 to 3 inches of organic mulch, such as pine needles or crushed bark, but allow an 8-inch space around the trunk. For the first year following planting, keep the soil moist.
Spreads Annabelle hydrangea?
Annabelle hydrangeas already occupy a lot of space given that they reach heights of between 3 and 5 feet. To fully expand throughout their active growth period, they require a lot of area, but they also typically spread between 4 and 6 feet. These hydrangeas have enormous flowers that are between 8 and 12 inches across when they are in bloom, which is normally in June and July but can occur later.
So seek for some open areas while deciding where to plant your Annabelle hydrangeas. The hydrangea bush should have enough room for you to support it, though, as its large blooms have a tendency to droop. Plant Addicts advises planting at least three Annabelle hydrangeas side by side so that they can support one another as they develop and flourish. To allow for plant growth, you should initially space them 3 to 4 feet apart.
Other alternatives for support include surrounding the plant with a short wire fence or planting Annabelle hydrangeas next to a decorative fence so you may stake the blooms. If you decide to use the short wire fence, set it up around the plant before the spring branch-growth phase so it can support the blossoms from below. Plant your hydrangea bushes 5 to 6 feet apart if you decide to go with one of these methods.
Should hydrangeas be divided?
Depending on how well established it is, a hydrangea will require different tools to split. More hardware is required the more developed it becomes!
Most Hydrangeas in pots may probably be divided by hand, with nothing more than a good pair of gardening gloves. For one that’s rooted in the ground, we’d propose adding the following tools:
To remove the roots out of the ground, more mature Hydrangeas may need a more powerful tool, like a pick or an axe.
The most important step in getting ready to divide your hydrangea, which isn’t even a tool, should be mentioned last:
the right moment. When they are dormant, in the spring or the fall, hydrangeas should be divided. Their root systems are more susceptible to damage in the summer since they are actively producing new growth.
How Big Do Annabelle Hydrangeas Get?
The Annabelle Hydrangea, which can reach a height of up to five feet and displays a stunning display of huge snow-white blossoms, is categorized as a mounding shrub due to its wide spreading when it is at its maximum size. The Annabelle Hydrangea is one of the most widely grown flowering shrub species in the world thanks to its stunning, fantastic blossoms and adaptability to full or partial sun.
How Fast Do Annabelle Hydrangeas Grow?
Annabelle hydrangeas planted in the spring will bloom in the middle to end of the summer. Annabelle hydrangeas may also bloom in the early fall, depending on the growing environment. This plant rests in dormancy until the next spring after its final flowering. With the right care, it can withstand harsh winters pretty well and will bloom for many years.
Can Annabelle Hydrangeas Take Full Sun?
Annabelle hydrangeas can be planted in full sun or partial shade, but as with most plants, too much direct sunshine can stress them out and make them wilt. In the warmer, southern parts of the US, when growing Annabelle Hydrangeas, keep in mind how much stronger the sun is in the summer and think about putting them in partial shade or covering plants for a few hours in the afternoon. The best locations for Annabelle Hydrangea planting are those that get full morning sun and half afternoon sun.
How Do You Prune an Annabelle Hydrangea?
In order to encourage a second cycle of magnificent blooms, Annabelle hydrangeas respond well to pruning by removing faded blossoms and a few inches of new growth. Wait until late September or early October before pruning. Never prune flowers until they have faded noticeably. An Annabelle Hydrangea plant’s thorough renewal pruning entails eliminating the oldest stalks all the way to the ground. Just before spring, cut any stems that are protruding above the soil’s surface to promote growth as the sun’s energy increases.
Overly dry soil
To keep Annabelles moist, plant them in rich, humus soil or mulch the soil with two to three inches of wood chips. Every Hydrangea has a short root system that is prone to drying out.
Diseases such as rust, powdery mildew, and leaf spots
Plant your annabelles in regions with good air circulation to protect them from these illnesses. Instead of utilizing overhead sprinklers to water plants, drip irrigation performs better at keeping plants disease-free. Plant diseases like mildew and leaf spot can be treated with fungicides on hydrangeas.
Pests such as mites or aphids
The Annabelle Hydrangea’s stems and leaves contain plant liquids that mites and aphids feed on, robbing the plant of the nourishment it needs to blossom. Sticky honeydew covering the leaves is a surefire symptom of an aphid or mite infestation. Plants can be treated with horticultural oils or insecticidal soap to get rid of mites or aphids.
When Do Annabelle Hydrangeas Bloom?
Beginning in late June, Annabelle Hydrangeas bloom all the way through mid to late September. Annabelles may bloom later if they are lightly pruned in the early spring as opposed to heavily pruned plants.
Are Annabelle Hydrangeas Deer Resistant?
Deer won’t deliberately seek for Annabelle Hydrangeas to eat, but if they do, they will happily munch on the flowers, leaves, and branches. When deer won’t leave Annabelle alone, there is deer repellent spray that is safe to apply on her. However, Annabelle Hydrangeas require monthly application of deer repellent spray to maximize its efficacy.
How much should Annabelle hydrangeas be pruned back in the fall?
- Annabelle hydrangeas, also known as smooth hydrangeas, bloom on fresh wood, or more specifically, the growth of the current season. The optimum time to prune your bushes is in the late fall or very early spring to ensure that you are not removing any buds.
- Your Annabelles can be deadheaded at any time to remove the wasted flowers. A harsh pruning can occasionally be beneficial for annabelles, but don’t do it every year.
- Go ahead and perform a harsh pruning in the late fall if your bushes are frail and lanky or if your blossoms are small. Reduce the stems to around 18 inches so that the new growth has a strong support system. In the spring, your bushes will develop in thickness and have larger blossoms.
Note from the author: Some professional gardeners advise pruning Annabelles in the late winter or early spring. Others contend that late fall pruning is acceptable. This is how it was described to me when I initially found it confusing: once the growing season begins, do not trim or chop back your Annabelles. So when should an Annabelle hydrangea be pruned? Pruning is acceptable in the very early spring, late winter, or late fall.
How do you stop the spread of Annabelle hydrangea?
Is there anything that can be done to prevent the hydrangea roots from spreading? On the side of our driveway, they “popped” up in a certain spot approximately 5 or 6 years ago. They have expanded excessively, like a wildfire. I tried to pluck them, but it was unsuccessful.
Persistence and a little hard work should be enough. What you want to preserve intact, edge. Cut the rhizomes (underground stems that resemble roots) with a sharp spade to separate the hydrangeas you want to maintain from those you want to get rid of. Whenever the undesirable stems appear, continuously prune them to the ground. These stems ought to become weaker and eventually perish. Alternately, carefully apply a complete vegetation killer to the unwanted sprouts. All plants, even the ones you want to maintain, risk injury or death if the rhizome is not severed before spraying. When using conventional or new environmentally friendly products, read and carefully abide by all label instructions. All of these items are plant killers and can harm or kill both your desired plants and weeds.
What occurs if hydrangeas are planted too closely together?
The most often query we receive when building a hedge is, “How far apart should I space my hydrangeas? The answer to this question relies on a number of variables, including the type of hydrangea you’re using, your location, and the style you want to achieve. As a general rule of thumb, focus on the plant’s width first. For instance, Incrediball smooth hydrangeas (seen above) mature to a height and width of 5 feet. As a result, plants can be planted with their centers 5 feet apart such that they will almost touch as they mature.
You might want to think about planting them a little closer if you don’t want to have to wait too long for your hedge to fill up. Plants can grow to their maximum size over a number of years, and in colder climates, this process might take considerably longer. When they are planted closer together, individual plants will eventually touch and overlap. The end product is a beautiful wall of blooms and greenery that is difficult to resist!
Although it may be tempting, be careful not to plant them too closely together. As a result of the restricted airflow caused by their near proximity, disease is more common. Maintain a sufficient distance between plants to allow for airflow and healthy plants (and happy gardeners). On every one of our plant pages, under the “additional information” heading in the “how to grow” tab, are spacing suggestions. You can put Incrediball hydrangeas 3 feet apart if you choose. However, it is recommended that they be planted 3-5 feet apart.
Depending on the plant spacing, you’ll need a certain number of plants for your hedge. To estimate how many plants you need for your area, try using our plant calculator!
