In U.S. Department of Agriculture hardiness zones 5 through 9, hydrangea (Hydrangea spp.) gardens are adorned with enormous, vibrant blooms. These shrubs, which share their frothy blossoms for the most of the summer and may grow between 4 and 12 feet tall with proper care, can live for decades.
Hydrangeas are hardy shrubs that, with proper care, can survive for up to 50 years. They require frequent watering during the growing season and prefer early light but afternoon shade. After the blossoms have faded, prune them in the fall so that they will have sturdy stems for the summer after. The hydrangeas may lose their blooms for a year while the plants heal if they are pruned when they are in bloom.
Common hydrangeas, sometimes known as bigleaf hydrangeas, bloom in a variety of hues, including blue, pink, and purple. These hydrangeas typically start to bloom in May, which is sooner than some other kinds. Usually, the plants keep producing blooms until July. According to the characteristics of the soil, bigleaf hydrangeas are known to shift their bloom colors; a plant that blooms pink one year may bloom blue the following. Aluminum sulfate, which is added to the soil, promotes blue flowers, whereas hydrated lime, which is added to alkaline soils, promotes pink blossoms. Ayesha, Nikko Blue, and Preziosa are cultivars.
Longer blooming than other hydrangeas, the smooth hydrangea (Hydrangea arborescens) frequently displays color from early June through September. The cultivars “Anabelle” in white and “Invincibelle Spirit” in pink are examples. Smooth hydrangeas often bloom on wood from the current year, which means you should severely prune them, in contrast to other hydrangeas that bloom best on ancient wood. Trim them to a height of 6 to 12 inches above ground.
The panicle hydrangea (Hydrangea paniculata) blooms later in the year because it prefers the heat of summer to the mild weather of spring. Panicle hydrangeas often begin blooming in July and continue through September. Their blossoms are initially white, but as fall approaches, they start to turn rusty pink.
However, if you relocate the plants or transplant one from a pot to the ground, the hydrangeas may not bloom for a year or perhaps two. Hydrangeas can produce big flowers in their first year. This does not imply that their time of flowering is over. Once the roots of the plants have recovered from the shock of transplantation, they should begin to blossom. To this end, keep the plants well-watered and treat them with a balanced fertilizer throughout the spring, summer, and fall.

Examine the blooms for signs of damage.
Look for hydrangeas at the store that have vibrant, robust green leaves and bouncy blossoms. Check the petals for any brown spots, which would signify sun damage, advises BloomThat’s production director Callie Bladow. “Additionally, because cut flowers are stored cold, keep an eye out for black petals that could mean the blooms have been in contact with a refrigerator’s side. A flowering hydrangea should feel solid, not flimsy or spongy.” A healthy bouquet should last up to two weeks if you select one.
Cut garden-grown flowers with a sharp floral knife.
If you’re fortunate enough to have garden hydrangeas, you may easily bring them inside for a lovely arrangement. While working outside, cut them on the bias (a 45-degree angle) using a sharp flower knife or clean kitchen shears, then put them in a dish of lukewarm water. The optimal time of day to trim hydrangea blossoms, according to Bladow, is early in the day. “Leave the others to continue blooming and just select the most fully developed and mature blooms. Hydrangeas with full flowers will appear more “papery” than those with young buds.”
Prep them with alum powder.
The sap that hydrangeas create at the base of their stems needs to be sealed off in order for them to absorb water. After making a bias cut in the stem, Bladow advises dipping it in alum powder, an onion powder that can be found in the spice section of your local supermarket. “All that’s needed is a quick dip of the stem’s bottom, followed immediately by the vase.” If you don’t have alum powder, you can get the same result by dipping the stem in boiling water for around 10 seconds. Additionally, cut the leaves off the stem because they will use up all the water in the vase.
Get creative arranging with different flowers.
You can choose to use a traditional arrangement of only hydrangeas or you can try blending in other flowers or utilizing unusual vases. Bladow explains, “I adore utilizing glass apothecary jars with larger bases and petite vase necks. “Another way we enjoy using hydrangeas in our designs is as grids for other flowers. Simply insert them into the flower head; the hydrangea’s multiple stems will hold other flowers in place.” Hydrangeas can be arranged with any kind of flowers. She suggests combining some foliage, such as lemon leaf or variegated pittosporum, with roses, dahlias, and freesia.
Change the water daily.
According to Bladow, hydrangeas prefer chilly water, which should be replaced every other day with a new snip of the stems. You can fill the vase with some plain cane sugar or flower food from your cupboard. Keep your arrangement away from harsh sunlight. Additionally, Bladow advises soaking the entire hydrangea for around 45 minutes in cool water if your flowers are acting downcast. Shake them off, trim the bottom of the stem, and then submerge them in flower food-infused water. Your hydrangeas’ lifespan could be extended and they might even come back to life.
How long do hydrangeas remain in bloom each year?
The hydrangea, which blooms in the spring and summer, is classified as a shrub. Despite the fact that they can grow to be pretty enormous showpieces in your yard, even a beginner gardener won’t need to know how to grow hydrangeas because these stunning plants practically grow themselves. The hydrangea, which can grow up to 15 feet tall, fills in a space swiftly and frequently in just one summer. Hydrangeas are perennial plants that grow in hardiness Zones 3 to 7. Hydrangea blooms can be the main plant in your landscape because they bloom in the spring and frequently continue into the early fall.
How long will my hydrangeas in pots last?
When hydrangeas outgrow their pot, they must be repotted in order to maintain their health. This often occurs every one to two years.
Once it has done flowering in the fall, carefully remove yours from the container it is now in. Make sure the new garden planter has drainage holes and is about an inch bigger in diameter than the old one. Plant it at the same depth as before.
Are hydrangeas evergreen?
Indoor hydrangeas are thought of as transient plants to enjoy while they last because they rarely survive winters. By imitating the seasonal variations that hydrangeas would encounter in nature, adventurous gardeners might attempt to keep their plants alive from year to year.
Buy from a trusted source
Unfortunately, the quality of your flowers may vary depending on where you purchase them. Or, and this is the worse, people frequently remove them from the buckets and fail to replace them! This results in blooms that have been dry for anything between a few minutes to a few hours.
This is fatal to a flower that adores and requires a lot of water. This, in my opinion, may make the difference between them only lasting a few days versus a week or longer!
Therefore, my first piece of advice is to purchase from a few different vendors and observe if a trend emerges. Usually, one vendor will have fresher flowers than the others. The farmer’s markets and my neighborhood Trader Joe’s are great for me.
In addition, I make sure that when I pick the flowers out of the bucket, they are all completely submerged in water. Additionally, look at how springlike the blooms are. The older ones frequently don’t actually wilt, but if you look closely, the blossoms are loose, and when you gently touch them, they don’t feel solid or springy. Those are the ones you ought to forget.
Put Them in Water Right Away
Bring them home and immediately immerse them in water. Don’t let yourself be tempted to run another errand or leave them in the car for too long. Hydrangeas are avid drinkers and don’t like to go without it for very long. As a result, the Latin origin of their name, “hydra,” is water.
They may not stay as long if I don’t get them into water immediately soon, perhaps since I live in Southern California and it is warm here.
While I put the remaining goods away, I prefer to fill the sink with tepid water (not ice cold) and place them inside immediately. Alternately, take a sizable glass or pitcher and place the items inside while you finish your current task. In either case, get them in the water as soon as you can.
Trim Them at Least a Half Inch
Once your vase is prepared, make sure to trim the bottom of the flowers by at least half an inch with a pair of sharp scissors or floral clippers. A recent, slightly angled incision enables the flower to absorb more water.
Additionally, I advise you to remove any leaves that fall below your water level, just as you would with any cut flower. They do this because it breeds germs and makes the water foul much faster, which makes the flowers miserable.
Use Flower Food in the Water
There are so many folks I’ve spoken to that don’t do this! Since the flowers are no longer receiving this nutrition from the soil, it is crucial to provide them good quality flower food (which is what those tiny packets that come with the flowers contain).
Unless it’s a particularly large vase, I advise using a little less than what is on the envelope. A little goes a long way, just like with any type of garden fertilizer. I typically use half to three-quarters of the packet for an average-sized vase or pitcher and the entire package only for really big amounts of water.
Change the Water Every Few Days
Water changes, which are typically done every two to three days, are another crucial consistency-related task. This applies to all types of cut flowers, not only hydrangeas, that you might have in your home.
They wilt much faster as a result of the water becoming hazy and beginning to contain bacteria. Every two to three days, I like to change the water, make another little cut, and add fresh flower food. This really does make a difference, in my opinion!
Emergency Revival Technique
Even with your greatest efforts, they occasionally wilt much sooner than you’d like. When hydrangeas do not receive the necessary water, they will wilt or begin to droop. When that happens, you might try giving them a relaxing, cool bath in the sink to try and revive them.
One of the rare flowers that can absorb water via the leaves and the blossoms as well as the stems is the hydrangea. When I notice any of mine drooping, I immediately fill the sink with cold, fresh water and soak them for about 10 minutes. You can even hold them upside down while immersed in running water; just make sure to soak the leaves as well.
After shaking off the excess water, I slightly trim them once more, change the water, and add fresh flower food. This works virtually all the time!
Even more seldom, I’ve been known to perform the “revival” many times, bringing them back to life for as long as a week!
We all have our own methods, but I’ve heard a few individuals claim they use boiling water, and I haven’t found it to be effective for me. The hydrangeas didn’t recover at all when I tried it; instead, they remained wilted, and I had to discard them.
This suggestion seems counter-intuitive to me because hydrangeas are heat-sensitive, and many florists even add ice cubes to the buckets to keep them cool. For my cut hydrangeas, I always use cold water, and I’ve had tremendous success doing so.
A couple other tips
Alum can also be used to resuscitate them. Alum can be obtained in some nurseries and the spice section of any normal supermarket store. This technique involves re-cutting the stem and dipping it in alum before dipping it in new water. Although I’ve never tried it, many people vouch for it.
To prevent bacterial growth, florists frequently add a dash of bleach (about 1/4 teaspoon per gallon of water). Again, I don’t do this, although I’ve heard it can be beneficial.
Last but not least, place your hydrangeas in a location that is out of direct sunlight, like next to a window. This really does change things! My hydrangeas die much more quickly if I leave them right close to the kitchen window than if I just have them a few feet away. Like in the garden, direct heat and/or sunlight are too much for them!
Your cut hydrangeas should last at least a week with these tips, typically longer! In fact, I took the pictures for this article over three weeks ago, and guess what? The hydrangeas on the kitchen counter are still flourishing! #truth
