Hydrangeas are show-stoppers in the spring and early summer with their massive, blousy blooms. However, the plant stops blooming after they have put on their flower show. This frustrates some gardeners, and the current dilemma is how to get hydrangeas to blossom again.
Can hydrangeas blossom again? There are reblooming hydrangea cultivars, however the plants only bloom once a year.
Do hydrangeas bloom every year?
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.
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.
Why aren’t my hydrangeas blooming?
All varieties of hydrangeas should begin to bloom in the early spring or mid- to late-summer, and each flower should endure for many weeks.
Too much fertilizer, not enough sunlight, transplant shock, moisture stress, frost damage on developing flower buds, and severe trimming of the old wood that supports this season’s new hydrangea blossoms are the causes of hydrangeas not blossoming.

How do I determine whether my hydrangea is a perennial?
Any landscaping would benefit from adding hydrangeas, but before you plant them, you should find out if you’ll need to do it again the following year. Are hydrangeas perennials? Or do they all last a year? You can take the right care of your hydrangeas and maintain the aesthetic appeal of your landscape by being aware of the optimal growing season and plant cycle.
Over 75 different species of hydrangeas make up this diverse group of plants. If the plant is not too severely damaged by the winter months, hydrangeas are called perennials, which means they grow back every year once they are planted.
This post is for you if you’re prepared to plan your landscape and begin planting. Stay put and read some more. The truth concerning whether or not all hydrangeas are perennials will be revealed shortly.
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.
What occurs if your hydrangeas aren’t pruned?
If and when you prune is the key to happy, healthy hydrangea flowers. Of course, fertilizing and offering the ideal environment have a lot to recommend them. However, if you don’t prune properly, your efforts will be in vain. Deadheading is not the same as trimming. Pruning refers to more drastic cutting to preserve shape or remove dead growth. However, feel free to discard spent blossoms or cut fresh ones to use in arrangements.
Hydrangeas can bloom on either fresh wood or old wood, depending on the species. The wood from which they blossom determines whether and when to prune.
Old wood-blooming hydrangeas do not require pruning and benefit from it. They’ll blossom more abundantly the next season if you leave them alone. But feel free to deadhead or gently thin. Just keep in mind that while new growth may appear, it won’t bloom until the following season. In our region, four different species blossom on aged wood. Additionally, they are not limited to the hues displayed here.
Climb using suckers. On your wall or trellis, resist the desire to remove the dormant growth.
The flower heads are more conical in appearance, and the leaves are large and resemble oak leaves. It’s a pleasant surprise for a hydrangea when its leaves turn reddish-orange in the fall.
They are very comparable to lacecap types, but smaller and with more compact leaves.
Pruning should be done in late winter or early spring on hydrangeas that bloom on new wood. Trim back to two feet to prune to shape. The next season’s blossoms are produced by strong, fresh growth that is encouraged by trimming. In our region, there are two types that bloom on fresh wood. They are also not restricted to the colors displayed.
Oakleaf variants are not included in cone-shaped blooms. Keep the blooms on throughout the winter to provide interest; even dried out, they are quite lovely.
regarded as a wild kind. They often have smaller blooms and leaves than Bigleaf variants and are completely white. They enjoy full sun and can grow very tall.
Knowing whether or when to prune now will help you avoid the disappointment of a hydrangea that doesn’t blossom. Don’t forget that a robust shrub will produce more gorgeous blossoms if it has well-draining soil and good organic fertilizer. Come on in, and we’ll show you where to go to develop your green thumb.
What should I feed hydrangeas to encourage blooming?
When purchasing fertilizer, check the labels to see how much nitrogen (N), phosphate (P), and potassium are present (K). A general-purpose, balanced fertilizer such a 10-10-10 N-P-K or 12-4-8 N-P-K is typically best for hydrangeas. Consider using a fertilizer with additional phosphorus if you want your hydrangea blossoms to be bigger and more numerous.
Since phosphorus is the middle element, fertilizer with the formula 10-20-10 will do. Choose a slow-release granular fertilizer with the designation “bloom boost” if you’re looking into it because it might also include more phosphorus.
If deadheaded, 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.
Do hydrangeas blossom again?
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.
The Authentic Hydrangea of Endless Summer
A gorgeous game-changer! The first continuously flowering hydrangea was called the Original Endless Summer. It’s also simple to maintain. Its season-long color-changing blossoms will amaze you.
late spring to early fall for blooms. Depending on the soil’s pH, blooms might be blue, purple, or pink.
Do hydrangeas grow in numbers?
When clipping hydrangeas to propagate the plant, when you cut and where you cut are two important considerations. The optimal period is when new stems first begin to stiffen, which is in late spring and early summer. New stems are prone to bending but are also easily snappable, and these cuttings have a strong growth tendency.
Cut a green, fragile branch that is 5 to 6 inches long and that is not in bloom. Make sure the cutting has at least three sets of leaf nodes—the points at which a leaf emerges from the branch—but only cut just below a leaf node. The bottom two leaf nodes’ lower leaves should be removed. Reduce the biggest leaves by around 50% in size as well.
The procedure can be sped up but is not required by dipping the cutting in rooting hormone. Place it with one or two nodes submerged in wet vermiculite or sterile medium in a well-drained container.
Fill the pot with water, cover it with plastic, or set it inside a plastic container with a lid to create a mini-greenhouse or humidity dome. Plant them after four to six weeks, when a strong root system has developed. Keep your cuttings away from the sun’s harsh rays.
