Endless Summer hydrangeas have an extremely extended flowering season and despite their delicate appearance, they are a sturdy, winter-hardy species. The luxuriant ball of pink, blue, or white petals and glossy leaves was created by a Minnesota nursery in 2004. The deciduous shrub drops its leaves in the fall before going dormant, and its dark green foliage turns burgundy in the fall. One of the plant’s distinctive qualities is its capacity to produce blossoms that, with the addition of a soil amendment, can change color from blue to pink or from pink to blue. With the addition of aluminum sulfate, one kind, the BloomStruck, can change from blue to a deeper blue-purple.
This evergreen floral shrub elevates any landscape. It just takes a few blooms of a hydrangea to properly fill a vase, making it a favorite at bridal showers and weddings. Hydrangeas are also often used as cut flowers.
Does the hydrangea Endless Summer bloom all summer long?
Continual Summer Depending on the region where you live, hydrangeas can bloom on both old and new growth from spring through summer or early summer to fall. They actually prefer partial shade to full sun.
Sun and shade
Continual Summer Half-shade, or around four hours of unobstructed direct sunshine every day, is ideal for hydrangea growth. The optimal scenario for them is early sun and afternoon shade.
Soil
Continual Summer Although they may grow in a variety of soils, hydrangeas require moisture to thrive. The most important thing to keep in mind regarding soil is that its hue can range from blue to purple to pink depending on how acidic or alkaline it is. Make sure your soil is acidic for a bluer hue. If it needs to be pinker, adjust it to be more alkaline.
Fertilizing
Use a fertilizer that has been carefully developed to fertilize your Endless Summer Hydrangea once in the spring or summer. Although a fast-release balanced fertilizer with an NPK value of 10-10-10 will also work, slow-release fertilizer is recommended.
Pruning
Endless Summer hydrangeas can bloom on both old and new growth, so you don’t need to prune them. However, you should remove any dead, sick, or infected branches as soon as you see them.
How are Endless Summer hydrangeas maintained in bloom?
You will get the most flowers by safeguarding the flower buds on the old wood since Endless Summer Hydrangeas bloom on both the previous season’s growth (“old wood”) and the current season’s growth (“new wood”). Don’t prune or trim back your bushes after August 1st in order to achieve this.
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.
Should Endless Summer hydrangeas have their old blooms removed?
According to Meyers, the species of hydrangeas will determine the optimal time to prune them. When the initial set of flowers emerges from the previous year’s growth in the spring on bigleaf hydrangeas like Endless Summer, she advises, “deadheading to remove the faded blossoms before the next flush arises.” As long as the cut is made before July or August, when the plant starts to create buds for the blooms of the following year, you can make a deeper cut for a longer stem. She advises removing the faded blooms off smooth hydrangeas as soon as they turn green in order to guarantee a second flush of smaller flowers in the fall.
Do hydrangeas have a second blooming season?
The summertime experience of entering a yard full with blooming hydrangeas is unmatched. If you enjoy the way hydrangeas appear, you want them to endure as long as they can. Do certain Hydrangeas rebloom more than once each season, you may be wondering? Which ones, if any?
More than once a season, some hydrangeas do rebloom. In particular, plants that bloom on both old and new wood do rebloom every season. Old wood is the first to bloom with flowers. The new wood generates blossoms later in the growing season. Endless Summer, Penny Mac, Let’s Dance Starlight, and Everlasting are cultivars that rebloom.
Your garden can remain lovely for a significant amount of the year if you choose to cultivate hydrangea kinds that bloom repeatedly throughout the season. Reblooming Hydrangeas will continue to bloom even if the first set of flower buds are unintentionally removed, making these varieties of Hydrangeas very advantageous for gardeners who worry about pruning Hydrangeas at the proper time.
Why isn’t my never-ending summer blooming?
According to Missouri Botanical Garden, the fact that Endless Summer hydrangeas can bloom on both old and new wood is what gives them their “endless” moniker. Only ancient wood can support the blooming of traditional big-leaf hydrangeas like “Nikko Blue” (Hydrangea macrophylla “Nikko Blue”). Old but still alive stems must be left on the plant after the flowering season is over because they will produce the flowers for the following season.
According to Missouri Botanical Garden, traditional smooth hydrangeas, including ‘Annabelle’ (Hydrangea arborescens ‘Annabelle’), bloom on fresh wood. When the flowering season is through, these can be clipped to the ground because the new growth will have fresh blossoms. Improper pruning, according to Plant Addicts, is one of the most frequent bloom-stopping errors you can make and a cause of your Endless Summer hydrangea’s failure to bloom on old wood.
For Endless Summer hydrangea varieties to remain in good flowering condition, you just need to remove dried flower heads, dead leaves, and entirely dead stems. The University of Florida advises cleaning your pruning shears to prevent spreading plant diseases to your flowers. Tools should be disinfected with a common household cleaner or soaked in diluted bleach solution.
Do hydrangeas bloom year-round?
If you want a garden that is interesting all year long, growing hydrangeas is a no-brainer.
The sculptural shapes of their dried, elegant paper flowers then create gorgeous silhouettes in the wintertime frost.
About two years ago, when I first became interested in hydrangeas, I thought of them as having a somewhat suburban reputation. Like many shrubs, too.
But there’s no denying that hydrangeas are “back” as I update this post in 2021! They are really simple to grow and provide so much for the garden.
I went to Signature Hydrangeas to speak with Roger Butler, a hydrangea specialist, on the fundamentals of selecting and cultivating hydrangeas. You may watch Growing Hydrangeas on YouTube by clicking here if you’d rather watch a video than read a blog post.
Following deadheading, do hydrangeas bloom again?
Hydrangeas cannot be revived by deadheading like other flowers can. Reblooming hydrangeas produce a second set of flowers on fresh stems later in the season compared to regular kinds, which only bloom once each season. When deadheading hydrangeas, the goal is to keep the shrubs looking tidy and to direct plant growth toward roots and leaves rather than seeds.
Many customers ask why their hydrangeas aren’t blooming. The primary reasons hydrangeas don’t bloom are incorrect pruning, bud damage due to winter and/or early spring weather, location and too much fertilizer.
There are hydrangea kinds that bloom on either fresh or old wood, or even both. Both new and old wood are the growth of the following year (spring), respectively.
- Consider that this year, you bought a Nikko Blue Hydrangea. For the next year, Nikko’s produce blooms in the fall. Your Nikko is therefore creating blooms this fall that will blossom in the spring.
- Therefore, you wouldn’t want to completely prune your Nikko Blue Hydrangea this fall while you are pruning your perennials. Pruning the Nikko Blue Hydrangea this fall would effectively mean cutting off your hydrangea flowers for the upcoming spring.
- The idea behind Endless Summer, a hydrangea variety that blooms on both old and new wood, is that the plant will set blooms this fall to blossom not only in the spring of the following year, but will also keep producing blooms in the spring of the following year to extend the blossoms into the summer.
- Once more, pruning your Endless Summer hydrangea in the fall would mean removing some of the flowers that would blossom in the spring.
The hydrangea’s plant tag will indicate whether it blooms on fresh wood, old wood, or both. It is typically preferable to wait until spring to prune your hydrangeas. As the plant grows, you’ll see stems that are fragile when bent and lack any leaves. Since these stems are dead and won’t produce any flowers, they should be clipped close to the plant’s base.
The second reason why your hydrangeas aren’t blooming is probably the weather. Buds of hydrangeas are extremely susceptible to cold. Therefore, it is a good idea to wrap your hydrangea for the winter if it is an old wood hydrangea. Keep in mind that old wood hydrangeas establish their blooms for the following spring in the fall. Therefore, you won’t have blossoms in the spring if the fall-produced buds are frozen in the winter.
You can wrap anything with regular burlap. Burlap should be wrapped around the plant and filled with mulch or leaves after the first hard frost and after the hydrangea’s leaves have dropped. In order for the buds to survive the winter and sprout the following spring, the plant receives insulation from this. Never wrap your hydrangeas in plastic. When warmer winter days arrive, the plant cannot breathe since plastic, unlike burlap, doesn’t breathe. As a result, the plant can heated to such high temperatures that it cooks within the plastic and perishes.
The second most frequent weather-related cause hydrangeas do not blossom is late spring killing frosts. We saw really chilly temperatures in April both this year and last year after beautiful spring days. When springtime temperatures drop below freezing, hydrangeas need to be covered with an old beach towel or sheet. Because of the temperature dip, there won’t be any blossoms.
The majority of hydrangeas require at least 3 to 4 hours of light per day to bloom. The best light is in the early morning, midday light is acceptable if it is dabbled light rather than beating sun, and afternoon sun is typically too hot. Check the plant label, though. Newer hydrangea cultivars are being created that can withstand more sun exposure time and sun intensity. A hydrangea in full sun will require much more watering than one in diffused light, so keep that in mind.
High nitrogen fertilizer should not be used to feed hydrangeas. Nitrogen is indicated by the first number on the fertilizer ratio. (The ratio stands for N, P, and K) For healthy leaves and general good growth, some nitrogen (N) is required; however, a ratio of 8-16-6 or any similar combination with a higher middle or phosphorus (P) value is preferred. The growth of roots and shoots is encouraged by phosphorus, which improves the blooming process.
Potash (K), the third element’s last quantity and the lowest ratio, is for plant hardiness. Because hydrangeas prefer acidic soil, they can be fertilized with fertilizers designed for such plants. Hydrangeas only require fertilizing twice a year, once in early spring and once in mid-summer. To avoid root burn, make sure the soil is always moist before applying a fertilizer.
