Historically, hydrangeas only had one blooming season. No longer! You may now pick from a wide selection of hydrangeas that bloom all summer long. Even now, you can prune these.
With reblooming hydrangeas, you can enjoy blossoms from June until the first frost since they bloom on both new and old growth. They’ll keep blooming long after other perennials and bushes with flowers have finished. Long-lasting flowers in shades of blue, violet, pink, white, or chartreuse give any garden vibrant splashes of color.
These hydrangeas also pull off a spectacular act. The color of the hydrangea varies according to how acidic your soil is. Beautiful blue hydrangeas are quite simple to make. All you have to do is add Espoma’s Organic Soil Acidifier to your soil.

Which hydrangeas have continuous blooming?
Endless Summer Hydrangeas live true to their name, producing enormous pink or blue mophead blooms all summer long on both new and old wood.
Endless Summer Hydrangeas are distinctive and raise the bar for the common hydrangea. Both old and new wood can be used to grow their gigantic, striking blossoms, allowing for an exceptionally lengthy flowering season and the possibility of reblooms. You may even make your Endless Summer Hydrangea unique by changing the pH of the soil to produce blooms that are either vibrant blue, delicate lavender, soft mauve, or deep pink.
Endless Summer Hydrangeas are a cold-hardy kind that are perfect for gardens outside of the South because they can even withstand frost.
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.
Should I remove the hydrangea’s dead flowers?
Your hydrangea shrubs’ blossoms appear to be withering or turning brown. No need to worry—this is merely a signal that it’s time to deadhead—remove the blossoms from the plant.
Deadheading hydrangeas doesn’t cause any damage to the plants at all. Flowering shrubs stop producing seeds when the spent blooms are removed, and instead focus their efforts on developing their roots and leaves. You will be doing your hydrangeas a favor by deadheading because this strengthens and makes plants healthier.
Why aren’t my Hydrangea Endless Summer blooming?
Your hydrangea shrubs may not be blooming for a few main reasons, including sun exposure, excessive watering, and excessive fertilization. Endless Summer hydrangeas appreciate dappled shade in the afternoon and morning sun. It may be too hot and intense for the blossoms to form if they are placed in full sun.
They are hardy
The species of hydrangea most tolerant of freezing temperatures is the panicle. They are dependable shrubs or tiny trees that thrive with little effort. Their sturdy, reddish-brown branches range from being straight to arching and occasionally bow from the weight of the enormous blossoms. Although something closer to 6 or 8 feet tall and wide is more typical, something up to 15 feet tall and wide is possible. Panicle hydrangeas are typically too large for small gardens, but anybody may enjoy them with careful pruning or by picking a tiny variety like ‘Dharuma’ or Quick FireTM.
Pruning doesn’t affect bloom
Panicle hydrangeas don’t mind being clipped, unlike bigleaf hydrangeas (H. macrophylla cvs., Zones 69). Typically in early spring, I advise trimming the plants back by about half of their height before the leaves appear, though this is optional if you have space for a larger plant. Due to space limitations in the trial beds, we had to start trimming, but the better habits and results we saw afterward encouraged us to keep doing it. The size of the hydrangeas with annual pruning is depicted in the chart below. Contrary to many bigleaf varieties, panicle hydrangeas bloom on new wood, thus trimming won’t stop them from producing blooms and might even make them bigger. Annual trimming, in contrast to some accounts, did not promote long, feeble stems that were unable to sustain the weighty blossoms. All the cultivars, with the exception of “Dolly,” were robust enough to support their blossoms.
Flower type and size vary
Panicle hydrangeas produce a mixture of beautiful, sterile florets and frothy, fertile florets in their flowers. The showy florets, which vary in size and number depending on the cultivar, create the protracted bloom show, which is accentuated by a transformation from white to various pink tones. Unsurprisingly, the breeding trend has been to enhance the pink hue of the wilting blooms. I employ the words “To distinguish between the two floral varieties of panicle hydrangea, use the terms lacy and “mop.” In contrast, Lacy describes an open panicle with showy florets scattered throughout the fertile flowers “Mop is a sign of an excess of colorful florets with fertile florets buried beneath.
Watch the pHbut don’t worry about deer
I discovered that the alkaline nature of our soils at the Chicago Botanic Garden, particularly in hot, dry weather, may contribute to panicle hydrangea foliar chlorosis. Consistent watering will guarantee healthier foliage and more robust bloom output in hot conditions. Panicle hydrangeas are resilient to urban environments and rarely encounter pests or illnesses. While some cultivars are frequently praised for their mildew tolerance, none of our plants ever developed powdery mildew. Deer also favor bigleaf hydrangeas, but they usually show less interest in panicle varieties.
They have some winter interest
I’m not crazy about going into detail about a plant’s winter characteristics, but I disagree with detractors who claim that panicle hydrangea lacks any winter appeal. When rimmed with frost or covered in snow, the faded brown blossoms add some color and structural interest. I prefer to leave them on till spring because I’m a lazy gardener at heart and I’ll be pruning the branches anyway. When the crispy panicles break off and roll across the garden like tiny tumbleweeds, it’s entertaining.
Do I need to take any extra steps to protect a hydrangea if I’m growing it outside of its proper growing zone? Should I cover them in burlap or another kind of covering like I might with other shrubs?
Giving it an additional blanket for the winter is a good idea if you’re trying to grow something in a somewhat hardy environment. You’ll likely need one or two more layers than someone who usually experiences the cold when you get off the plane from Hawaii to Minnesota in January. Burlap does offer some nice protection for the shrub, but you might also want to consider enclosing the shrub in a metal cage and stuffing the cage with pine straw or leaves before wrapping it in burlap.
How often should hydrangeas be watered over winter?
You shouldn’t have to water plants all winter long if you live somewhere that gets snow. You might need to apply once per month or so if you live in a warmer area without snow and little winter rain. You can leave it unless it’s completely dry because the plants’ water requirements are small because they aren’t growing and have no leaves. The same is true of container-grown hydrangeas. Easy as pie.
First Editions ‘Vanilla Strawberry’ Hydrangea
A panicle hydrangea called “Vanilla Strawberry” blooms from midsummer until the end of the season with sweet-colored blossoms. Cut down or shape plants in the late winter or early spring before blooms appear. Vanilla Strawberry is a standard that can grow to a height of 6 feet.
Don’t give up on it in the winter and fall. This time of year, they are intended to shed their leaves. If there isn’t snow cover, make sure it keeps hydrated all winter. The plants still need some hydration at their roots even though they are dormant. Snow cover serves as a water source as well as insulation. Make sure you have enough rain or water to get them through if you live somewhere where it doesn’t snow or doesn’t receive snow. Additionally, make sure mulch, such as wood chips, oak leaves, pine straw, or another type, is placed over the hydrangea’s base. Snow or no snow, it provides the necessary insulation as well as some extra defense against hungry rats and rabbits in the winter.
When trimming other plants in the late winter, you might be tempted to prune hydrangeas as well, but McEnaney advises that you should first identify the type of hydrangea you have before using pruning shears.
Remember, he says, to offer a minor clip in the spring if you have a reblooming or mophead hydrangea.
Late winter is the time to prune down cone-shaped hydrangeas by a third to a half. Prune a cylindrical oakleaf variety after midsummer flowering if you have one.
When in doubt, McEnaney advises against pruning in the fall.
You run the risk of jeopardizing your flowers for the following year by cutting off blooms that grow in the fall. Simply be patient and wait until spring to prune after this season’s blooms have provided you with some winter appeal.
Ask for assistance from a nearby nursery, garden center, county extension office, or even another gardener to identify it if you are unsure of the variety.
According to him, too much fertilizer can be detrimental.
The element that promotes bloom production and gives you the most value for your money is phosphorus, so seek for a fertilizer with a high concentration of it when you’re at your neighborhood garden center. Follow the instructions on the fertilizer package and avoid overfertilizing to avoid burning the root system and preventing the development of flowers. If anything, one more application of fertilizer in the middle of the summer is beneficial, but make sure to cease fertilizing by early fall.
