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 is a hydrangea split?
Consider splitting or dividing the plant if your hydrangeas start to take up more area in the garden. Push the two sections aside to expose the root ball or crown, then divide the bush in half. Use a shovel to compel the parts apart. Remove one piece slowly, preserving as much of the root system as you can. When you notice new growth, add additional topsoil around the parent plant’s root system and continue watering as usual.
When can a hydrangea be split?
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. We would advise including the following tools for one that is rooted in the ground:
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.
Do hydrangeas need to be pruned before winter?
If and when you prune is the key to happy, healthy hydrangea flowers. Of course, fertilizing and offering the ideal environment have a lot to recommend them. However, if you don’t prune properly, your efforts will be in vain. Deadheading is not the same as trimming. Pruning refers to more drastic cutting to preserve shape or remove dead growth. However, feel free to discard spent blossoms or cut fresh ones to use in arrangements.
Hydrangeas can bloom on either fresh wood or old wood, depending on the species. The wood from which they blossom determines whether and when to prune.
Old wood-blooming hydrangeas do not require pruning and benefit from it. They’ll blossom more abundantly the next season if you leave them alone. But feel free to deadhead or gently thin. Just keep in mind that while new growth may appear, it won’t bloom until the following season. In our region, four different species blossom on aged wood. Additionally, they are not limited to the hues displayed here.
Climb using suckers. On your wall or trellis, resist the desire to remove the dormant growth.
The flower heads are more conical in appearance, and the leaves are large and resemble oak leaves. It’s a pleasant surprise for a hydrangea when its leaves turn reddish-orange in the fall.
They are very comparable to lacecap types, but smaller and with more compact leaves.
Pruning should be done in late winter or early spring on hydrangeas that bloom on new wood. Trim back to two feet to prune to shape. The next season’s blossoms are produced by strong, fresh growth that is encouraged by trimming. In our region, there are two types that bloom on fresh wood. They are also not restricted to the colors displayed.
Oakleaf variants are not included in cone-shaped blooms. Keep the blooms on throughout the winter to provide interest; even dried out, they are quite lovely.
regarded as a wild kind. They often have smaller blooms and leaves than Bigleaf variants and are completely white. They enjoy full sun and can grow very tall.
Knowing whether or when to prune now will help you avoid the disappointment of a hydrangea that doesn’t blossom. Don’t forget that a robust shrub will produce more gorgeous blossoms if it has well-draining soil and good organic fertilizer. Come on in, and we’ll show you where to go to develop your green thumb.
Should I prune my hydrangea before relocating it?
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 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!
