Hydrangeas make wonderful ornamental shrubs because they produce large, vibrant blooms that endure the entire growing season. They aren’t difficult to grow either; in fact, the main difficulty is frequently preventing them from outgrowing their available space. Many gardeners have questioned whether they can divide one Hydrangea into multiple plants in order to make the most of its quick growth as a result of this.
The majority of hydrangea varieties may be split quite easily, though the longer the plant has been in the ground, the more work it will take. Caning shrub varieties respond best to this mode of propagation. You should probably take cuttings for climbing or panicle hydrangeas.
A Hydrangea must have at least two separate stems poking out of the ground in order to be separated. Choosing a smaller branch from an older shrub may be preferable to trying to divide the primary clump of stems in half. These shrubs’ main root clusters are very tough as they age!
When should hydrangeas be divided?
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 mature hydrangea divided?
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.
Can you replace a portion of hydrangea that has been cut off?
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 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.
Can hydrangeas survive in complete shade?
It’s no surprise that hydrangeas have grown to be so well-liked among gardeners given their profusion of blossoms and remarkable adaptability. There is a hydrangea for almost every garden because there are so many different types. They are certain to provide you happiness year after year if you give them a sunny place with well-draining soil. Will hydrangeas flourish in the shadow, though?
Full sun (more than 6 hours of direct sunlight) to part sun is ideal for hydrangea growth (4-6 hours sun). All hydrangeas can tolerate some shade, but the timing and nature of the shade should be taken into account. As long as they receive some early sun, they can spend the warmest part of the day in complete shade. In sweltering conditions, this is especially true. They don’t flower as frequently, though, and their stems tend to be weaker and floppier if they don’t get enough sun.
Don’t let a little shadow ruin your plans for a hydrangea garden. A list of hydrangeas that can tolerate shadow better than others has been assembled.
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!
Can I move a big hydrangea?
A: I want to relocate a sizable hydrangea plant to a different area of my garden. What time of year is ideal for this?
A huge hydrangea plant can be moved, but it will be very heavy so plan to seek assistance. Make sure to remove the largest portion of the hydrangea root ball.
Hydrangea shrubs can be planted in spring or fall, but the majority of the publications I read advise waiting for cooler weather and moving the bushes in late fall or early spring, when the plants are dormant but the soil is still usable.
The plant’s mature, unpruned size should fit in the new planting location. Pick a location with soil that drains effectively. Rich organic matter in the soil will help it retain moisture. Keep in mind that soil that is damp can nonetheless be effectively drained. A spot where water pools or takes a long time to drain should be avoided after a strong downpour.
An excellent location will not be completely shaded in the afternoon. To blossom, hydrangeas require sunlight—not intense sunlight, but also not complete shadow. Each kind of hydrangea has a different tolerance for sun exposure.
After relocating, give the transplanted hydrangea one good soak in water. After relocating, avoid overwatering, but give the plant additional watering over the course of the following two summers as it gets acclimated.
A: I have two healthy fig trees (same cutting), but for the second year in a row, neither of them has produced any figs. Advice?
A fig tree is something I’ve never grown. I’ve looked at a few sources and can suggest the following. I am aware that the cuttings are from the same tree and of the same age, but I am unaware of the reader’s growth practices.
Starting with the potential causes of a fig tree not producing fruit:
It isn’t old enough: A fig tree usually starts bearing fruit between the ages of two and six. It makes sense that two trees that were grown from the same cutting will develop similarly and reach maturity around the same time.
An issue with gardening is having too much nitrogen. A plant with too much nitrogen will have healthy leaves but no fruit. The majority of the sources I looked at advised making only one sparing spring fertilizer application.
Fig trees don’t like to be too wet or too dry, which causes water stress. Make sure the soil has good drainage, and keep it evenly moist but not soggy or humid.
Does this resolve the issue? I’m not sure, but I think the first step would be to look at the circumstances that each plant is facing. Do you drink more or less water? Does one plant receive run-off fertilizer from an adjacent lawn if it is planted in the ground? Does the soil differ in any way? What has changed?
If you’ve grown figs and have any tips for this reader, send them to me and I’ll share them with them.
Even though it’s only September, you should get your amaryllis bulbs from the previous winter ready to bloom once more as there are only roughly 15 weeks before Christmas. If you followed my instructions, you would have cut the flower stems back after they bloomed and preserved the greens through the winter. You will then plant them this spring and let them to thrive throughout summer. The containers are filled with lush, deep green leaves.
Move the pots inside and stop watering them right away. The bulbs need to become dormant.
They should be kept in a dark, cool (not cold) place. Once the leaf has dried up and become shriveled, remove it. Before they begin to grow once more, the bulbs will rest for eight to twelve weeks.
Water the bulbs and relocate them to a location with bright but indirect light as soon as you see fresh growth. After emerging from dormancy, the bulbs should flower four to six weeks later. After 12 weeks, if they still don’t sprout, try watering them and moving them into light.
Until the first frost, I normally leave my amaryllis outside. Because of this, I had lovely flowers in February, when I really value them. For my Christmas display, I usually buy fresh bulbs, however after a while, I have a lot of bulbs. Can there ever be too many amaryllis flowers, though?
I have finally recovered from Lyme disease symptoms after taking medications and avoiding sunshine for more than two months. Every time you walk outside, take precautions against ticks to spare yourself a lot of pain. Although that is a story for another day, the garden is a jungle.
This orchard is nearby, accessible, and reasonable—only it’s 15 minutes from my house. James Hamilton founded it in 1974, and his twin sons Ron and Rick now oversee it. The family website states that the orchard started providing pick your own in 2015. On a Saturday afternoon, my friend Betty Cauler and I went and came home with a lot of gorgeous nectarines and peaches (Flaming Fury) (Fantasia).
There are now also apples accessible. Find a local producer and enjoy the delight of freshly picked, locally grown fruit if you are unable to do so yourself.
