Hydrangeas will indeed reappear each year if they do not perish during the winter. Though not all gift hydrangeas are bred to grow especially winter-hardy. Thus, hydraneas occasionally do not endure the winter. However, most hydrangeas will reappear each year.
How can I make my hydrangea bloom again?
A hydrangea’s roots can be burned if too much fertilizer is used, which will likely result in the plant dying, turning brown, and drooping.
As such, hydrangeas are not heavy feeders and do not require annual feeding in the same manner as roses do, and doing so can actually be detrimental.
Hydrangeas frequently develop and flower to their full potential if they are planted in healthy soil or the soil has been modified with compost prior to planting.
The hydrangea should flourish if a 1-inch-thick layer of mulch is applied around it to assist retain moisture and supply nutrients to the soil (compost and leaf mould are ideal options).
Only in the following circumstances should fertilizer be used:
- Planting the hydrangea in sandy soil (which is nutrient poor).
- The hydrangea is in a pot or other container where the roots have used up all the nutrients in the soil.
In these two situations, it is recommended to use an all-purpose fertilizer with equal parts nitrogen, phosphorus, and potassium (NPK) that is applied once in the spring and is generally well-balanced.
The roots of your hydrangea can be burned by well-rotted manure, especially if it is added to the soil after planting. However, if the manure is made from poultry manure, it may contain a lot of nitrogen.
To prevent issues, I advise putting compost to the soil as a soil amendment (fresh manure is particularly harmful, always allow it to rot for a year or so before using manure on your garden).
If your hydrangea is exhibiting indications of stress as a result of being recently planted in soil that has been altered with manure, move it to a location with soil and compost, and it should recover.
Reduce the amount of fertilizer used and remove any discolored leaves or blossoms. To assist the hydrangea recover, thoroughly water it in an effort to dilute the soil’s water-soluble nitrogen.
Key Takeaways:
- Most frequently, hydrangea deaths are caused by the soil’s lack of moisture. Because they need their soil to be continually moist, hydrangeas will droop or even die in a dry environment.
- Drought, transplant shock, frost damage, and too much sun can all cause hydrangeas to perish.
- If the pot base doesn’t have drainage holes, potted hydrangeas may succumb to root rot. Small containers may dry out too rapidly and limit root expansion.
- Water hydrangeas liberally, cover them with compost mulch, and keep them out of the sun and wind to help them recover. To encourage healthy growth, remove any growth that has been sunburned or damaged by frost.
After the winter, do hydrangeas grow back?
If you have hydrangeas like panicle and smooth hydrangeas, which set bloom buds on current season wood, you can be more liberal about pruning. Winter or fall are the optimum times to prune them. Even if you trim canes to the ground when the bushes are dormant, they will grow back and flower in the spring. However, cutting stems all the way to the ground over time weakens them, so you might need to stake the plants to keep them standing. This severe trimming could eventually make the plant grow back weaker.
How can I determine whether my hydrangea will grow again?
That mass of hydrangea sticks starts to produce new growth in the spring, either from the crown (or base) of the plant or from a cane. By about May, if you see no new growth at all, your plant may have suffered from “winter kill,” which was undoubtedly brought on by too-cold, freezing temperatures that were perhaps made worse by a drying wind.
The New York Botanical Garden’s Lorraine Ballato, a horticulture and educator, advises that you scratch some stems with your fingernail to be certain. A stem will show some green under the bark if it is alive. By the end of spring, if you can’t discover any living stems and no sprouts are emerging from the plant’s base, your hydrangea is dead. Remove the plant and try a more tolerant of the cold kind.
But keep in mind that the USDA hardiness zones measure a plant’s capacity for merely surviving, or whether its roots can endure the winter. According to Ballato’s essay for the National Garden Bureau, when it comes to hydrangeas, you also need to know if the stems can endure as many hydrangea kinds only bloom on wood that is a year old. What’s the sense of having a hydrangea if you can’t obtain blooms? To be sure, she advises asking a nearby nursery or extension office about the varieties of hydrangea that do well in your area.
What happens if hydrangeas are cut all the way down?
These hydrangeas are simple to manage because they bloom each year no matter how they are taken care of or treated. They can be cut down to the ground in the fall and will reappear the next spring with an abundance of blossoms. However, over time, this severe trimming might make the plant gradually weaker.
My hydrangea died; why?
When a hydrangea dies, it is typically because the soil is too dry or it is exposed to too much sunshine, which causes the leaves to wilt and turn brown. Frost damage can easily affect springtime new development, turning the leaves and flower buds dark and mushy and giving them a dead aspect.
Here is a reference table listing the symptoms and most frequent causes of hydrangea death:

Can hydrangeas be kept in pots?
Do hydrangeas thrive in containers? Given that potted hydrangeas received as gifts rarely survive longer than a few weeks, it’s a reasonable question. The good news is that they can, given the proper treatment. Growing hydrangeas in pots is a great idea because they can grow to be fairly large and have beautiful blossoms all summer long. Learn more about container-grown hydrangea plants and how to take care of hydrangea in pots by reading on.
Why didn’t my hydrangea bloom again?
According to the University of Florida IFAS Extension, hydrangea (Hydrangea spp.) are loved by gardeners for their colorful flowers that develop as lace caps, panicles, or mop heads and are hardy in U.S. Department of Agriculture plant hardiness zones 3 through 11, depending on the species. Despite being a wonderful choice for novice gardeners because to their low maintenance requirements, hydrangeas occasionally fail to produce new growth following the winter. If you can identify the reason why your shrub died, you can make future hydrangea plantings that will keep your landscape looking lovely from one season to the next.
Tip
A hydrangea that doesn’t reseed itself after the winter can signify a number of different issues. The plant may have been harmed by a fungus, an insect infestation, or a lack of moisture.
Cut back these shrubs in late winter before new growth begins
Shrubs that flower on young wood typically start blooming later than old-growth bloomers, beginning in June and continuing until the first frost, because they need to grow and set buds the same year that they bloom. As long as you avoid trimming when the flower buds are opening, these shrubs are understanding if it is not done at a specific period.
1. Trim the flowers all the way back for larger blooms.
These bushes can be completely removed from the ground in late winter or the beginning of spring. If cut severely like this every year, smooth hydrangeas will produce much larger flowers, but many gardeners prefer smaller blooms on stronger stems.
2. Maintain an old growth foundation to lessen flopping
Especially after watering from above or after a heavy storm, the branches of some hydrangeas frequently topple over from the weight of their blooms. Cutting the stems to a height of 18 to 24 inches will help to reduce this flopping by creating a strong framework for fresh growth.

After the winter, what should you do with hydrangeas?
Hydrangeas are stunning flowering plants with showy flowers that provide color and drama to the summer garden, but if they don’t receive the right care and attention, they may be finicky. Late winter hydrangea care must be done correctly. Disappointment might result from improper pruning, other typical blunders, challenging weather, and more. Fortunately, my radio guest this week, Lorraine Ballato, is an authority in hydrangeas who can assist you in overcoming the most difficult hydrangea problems.
Lorraine is a hydrangea expert, lecturer, writer, and photographer who specializes in gardens. In fact, she wrote the book Success with Hydrangeas: A Gardener’s Guide on hydrangea maintenance. She claims that hydrangeas are one of those plants that have a bit of a diva complex and are picky about how gardeners care for them. She advises gardeners to remember that what works in one area won’t necessarily be the ideal strategy in another. The ideal winter care for a hydrangea in Washington may be the worst possible care for one in North Carolina. And various hydrangea kinds have varied requirements, she continues.
Hydrangea Care in Deer Country
In zone 5b, where Lorraine resides, March is a chilly month. There are two to three feet of snow on the ground, and she can see deer footprints there, indicating that they are out grazing.
“If you live anywhere near deer habitat, Lorraine advises that you get outside and spray as soon as it warms up and becomes dry since this is the time of year when they really start to destroy everything. Before all the snow melts and before the does give birth, you may teach the deer that your garden is not their salad bar. The deer are hungry and pregnant. Don’t wait; the does will teach the fawns where to eat.
When using sprays, make sure you are facing the wind “Lorraine advises, and she means it, “You don’t want to be downwind of any deer spray that you use.” Any clothing you are wearing should be washed as soon as you are through spraying.
There are systemic deer repellents in addition to spray repellents. When plants are actively growing, systemics are sprayed. Through their roots, the plants absorb substances like denatonium benzoate, which gives the leaves a harsh flavor that keeps deer away. These can be used on ornamental plants but are not intended for food crops.
I live in zone 7b, where dormant plants will soon begin to leaf out, which is simply food for deer. I don’t have deer fences on my land, therefore my family of 13 deer feel free to roam about. You can listen to my chat with landscape design expert Karen Chapman about how she keeps deer away from the plants on her remote property in the Pacific Northwest for fence-free ideas to avoid deer from devouring your food garden and beautiful plants.
These 13 deer like my fence-free land and will soon be enjoying the dormant shrubs that are just beginning to leaf out. Here are a few of them.
Prepare Before Pruning
Make sure you have the appropriate instruments for the job, that they are all sharp and clean, before beginning to prune shrubs. Cutting can spread infections that were on tools that had contact with infected plant material the previous year.
In order to avoid the spread of diseases, Lorraine also suggests cleaning pruning equipment thoroughly before and after each plant. She uses rubbing alcohol in a spray bottle or antiseptic wipes. She does not advise using bleach because it will corrode metal surfaces.
Pruners come in two varieties, each of which is used for a distinct job. With a motion similar to a pair of scissors, a bypass pruner passes its blades by one another. A dull side of an anvil pruner is crushed by a sharp blade that presses down on it.
Anything that is alive should be chopped with a bypass pruner. Lorraine advises cutting at a 45-degree angle since it will result in a good, clean cut. Deadwood can be cut using an anvil pruner in the meanwhile. She cautions that using one on live wood will damage the plant.
Give anything that is alive a nice, clean cut with a bypass pruner. To cut, Lorraine advises a 45-degree angle. Lorraine Ballato is pictured.
Bear in mind that although appearing to be dead, branches are actually alive. Some gardeners make the error of believing the top growth on their hydrangeas is completely dead, so they chop it all the way down. According to Lorraine, they pulled off all of the flower buds that were going to bloom that year, which is how they end up with a green bush devoid of blooms.
The scratch test is what Lorraine employs to determine whether a plant component is alive or dead: If the stem turns green after being scratched, it is alive. It is dead if the urine turns brown.
To see if a stem is still green, use the scratch test. It is dead if the urine turns brown. Lorraine Ballato is pictured.
According to Lorraine, every cut a gardener makes will encourage new growth. In the spring, pruning before the temperature has warmed up can make a plant wake up too early. That will deprive the plant of the energy it needs to really emerge from hibernation, and the new growth will be more susceptible to the cold. The plant will be more vulnerable to pests and disease if it dies back.
Take care of that decayed, ill, or damaged wood if you’re in a warmer climate, Lorraine advises. If you don’t feel like pruning right now, she suggests going fishing instead.
Even on a 50-degree day, according to Lorraine, ice, snow, and cutting instruments don’t mix. The wait will benefit the plants the most, and it is not worth the risk.
Hydrangeas shouldn’t be pruned before the last date of the last frost since pruning encourages development, and new growth is readily harmed in cold weather. Lorraine Ballato is pictured.
New-Wood Hydrangeas and Old-Wood Hydrangeas
Not all hydrangeas grow in the same ways. Some flower on the fresh growth of the year, whilst old-wood varieties flower on the growth of the year before.
A fresh-wood hydrangea will develop new buds and then bloom if you prune it in the spring. However, spring trimming on an old-wood hydrangea will eliminate the flower buds, so the plant won’t bloom that year. If you must prune old-wood varieties, do so as soon as their summer flowering buds appear. Search for the “broccoli, claims Lorraine. That is how buds appear as they approach blossoming. Leave the broccoli alone and only remove obviously sick or dead wood.
On an old-wood kind, the buds start to resemble broccoli as they get closer to blossoming. Only remove sick or dead wood, leaving the healthy wood alone “broccoli unbroken. The red-circled bud is dead and can be removed without risk. Lorraine Ballato is pictured.
Clues to Identify Hydrangeas
Some examples of new-wood hydrangeas include panicle hydrangeas (Hydrangea paniculata), such as Limelight, and woodland or smooth hydrangeas (Hydrangea arborescens), such as Annabelle, Incrediball, and Invincibelle. However, you might not be familiar with the name of the hydrangeas you have if you didn’t choose them yourself. Perhaps you received plants when you moved into a new home. In that situation, Lorraine advises against taking any action the first year, saying that it is best to wait until you have a firm grasp of your garden’s capabilities.
A significant focal point in the landscape, this Hydrangea paniculata “Tardiva” has been trimmed into a tree form. Lorraine Ballato is pictured.
To tell if a hydrangea blooms on fresh wood or old wood, there are a few signs to watch for. For instance, a panicle hydrangea, a new-wood type, may have conical-shaped blooms, but it’s also important to check at the foliage. Hydrangea quercifolia, popularly known as oakleaf hydrangea, is an old-wood bloomer that can also produce conical blooms.
The conical-shaped Snow Queen hydrangea blooms on mature growth and has oak-leaf shaped leaves. Lorraine Ballato is pictured.
Bigleaf hydrangeas are always going to be blue or turn blue when exposed to a soil acidifier (Hydrangea macrophylla). The Endless Summer kinds of bigleaf hydrangeas bloom on both old wood and new growth, unlike most of them which only bloom on old wood.
Bigleaf hydrangeas with mopheads, or pink pompom blossoms, are sometimes mistaken for mountain hydrangeas (Hydrangea serrata). On aged wood, mountain hydrangeas bloom.
The hydrangea serrata “Blue Billow” is more than merely lovely. Additionally, it is the hydrangea kind that tolerates shadow the best. Lorraine Ballato is pictured.
Lacecap (flat) blooms on hydrangeas could indicate either a mountain or a bigleaf variety, therefore they are insufficient justification for taking action. To get a better sense, Lorraine advises looking at the foliage, or spending the season watching the plant and noting when it flowers and how it grows. Does it alter its color? Can it bloom again?
Japanese highlands are the source of mountain hydrangeas, which are more resilient. Even in years when it was too cold for other types to blossom, they can.
Mountain or bigleaf hydrangeas with lacecap (flat) blooms are both possible. Lorraine Ballato is pictured.
How to Care for a Reblooming Hydrangea
Rebloomers should not be pruned at the beginning of spring; instead, treat them like old-wood-only hydrangeas. However, there is a way to promote additional blooms because they have the ability to set out flower buds for that season on new growth as well. Cutting off the dead stem tips will allow growth hormones to migrate up the plant when the terminal flower, which is the blossom at the stem’s tip, dies. Flowers will then grow up the stem’s sides.
Reblooming hydrangeas should be treated as old-wood-only hydrangeas and shouldn’t be pruned in the early spring. Lorraine Ballato is pictured.
Lorraine claims that flower buds on old wood simply won’t survive the winter in extremely cold places, like Minnesota. The correct course of action in those situations is to remove the rebloomers from the garden in April or early May and promote new growth that will bloom later, in mid-July or August.
If cold-climate gardeners grow hydrangeas that only produce new buds once a year, they might never see flowers. Reblooming or continuously blooming hydrangeas are the best option for colder climates because of this, in Lorraine’s opinion. (Blue Enchantress is her favorite prolific rebloomer.)
A rebloomer is a blue enchantress hydrangea, for instance. When the stem’s tip is clipped, fresh flower buds will grow up it. Lorraine Ballato is pictured.
Sun, Shade and Hydrangeas
In the past, hydrangeas were not sun-tolerant. Some more recent cultivars can survive full sun, but only to a certain extent.
According to Lorraine, it is not possible to grow bigleaf, mountain, oakleaf, and climbing hydrangeas in full light in the South. They’ll burn up. The panicle hydrangea, which adores the sun, is the only variety of hydrangea that can tolerate full light wherever it grows.
Bigleaf and mountain hydrangeas thrive in partial sunlight, ideally in the morning.
Typically, hydrangeas thrive in partial sun. Hydrangeas can burn in full sun, particularly in the South. Lorraine Ballato is pictured.
Wind and Hydrangeas
Lorraine claimed that it took her almost ten years to realize how crucial it is to shield hydrangeas from wind in a chilly region. A fence, a shed, or a tree or plant with winter-enduring foliage, such as an azalea or rhododendron, will shield the cold winds that damage flower buds.
It’s crucial to provide hydrangeas with winter wind protection, whether it be in the form of a fence, a shed, or a plant with evergreen foliage. Lorraine Ballato is pictured.
Watering Hydrangeas Without Drowning Them
Gardeners frequently flood the area with water as hydrangea foliage starts to wilt in the midday sun. Instead, Lorraine advises taking a break and coming back later. If the soil is properly amended with plenty of compost and a thick layer of mulch, the foliage will rehydrate and perk back up after the sun has been off the plants for a bit.
A plant can temporarily shelter itself from the hot sun by collapsing its leaf. Hours later, there may be a problem if the foliage has not revived. Other plants might be absorbing the water more quickly than the hydrangea can, or the soil may not be storing moisture.
Plants use droopy leaves as a defense against the intense sun. Wait a few hours before dousing it in water; the foliage will revive spontaneously after that. Lorraine Ballato is pictured.
