The beautiful thing about Endless Summer hydrangeas is that, unlike other hydrangeas, you don’t have to cut them back to the ground. You can let them all winter long to get twice as many flowers the following spring because they bloom on both the growth from past years and the growth from the current season. The hydrangea should NOT be cut back in the fall.
How much should Endless Summer hydrangeas be pruned back in the fall?
Many plants can be rejuvenated through pruning, resulting in lush new foliage and gorgeous blossoms. An example of a plant that gains from this method is Endless Summer Hydrangeas. Pruning them in the early spring will help them get ready for the season. A little effort today will result in this year’s growth being strong. Make sure your hydrangeas are of the Endless Summer type as it’s one of the rare breeds that blooms the year after it’s been clipped. Typically, pink- or blue-flowered Endless Summer Hydrangeas are the ones that bloom for the majority of the summer. The soonest after it finishes blooming is the ideal time to prune your hydrangea for shape and size if it is not an Endless Summer or if you are unsure of its variety. By doing this, you’ll avoid unintentionally eliminating the buds it will set for the next year.
The best tools for the operation are a pair of clean bypass pruners, which operate similarly to scissors. Cleaning pruners using common household cleansers like Lysol can help stop the spread of disease. Make an angle away from the bud and trim your hydrangeas back to about one foot from the ground. A lovely shape can be achieved by gently raising the center. One of these branches should be cut off if any other branches are crossing it.
Throughout the growing season, pruning can be done to get rid of any diseased, harmed, or dead growth. Any pruning done outside of these times will expose your plant to stress and disease risks.
How should Endless Summer hydrangeas be cared for in the fall?
For those of us who live in northern climes with more severe winters, The Endless Summer series represents a milestone in hydrangea breeding.
Older hydrangea kinds only produced flowers on old wood or stems that had grown the previous year. All flowers for the following season were gone once that growth was destroyed due to harsh winter circumstances, damage, or unintentional autumn trimming.
The plants in the Endless Summer series are significantly more adaptable in the environment because they bloom on both new and old wood. The plants won’t generate many, if any, buds on the growth of the current season, though, if the plants are not properly nourished in the spring.
Any Endless Summer variety will grow best in an easterly direction or in a spot in the garden that receives morning sun and afternoon shade. To make a richer soil that will store nutrients and fertilizers better and retain more moisture, use a decent compost.
Use Plant-tone and granular lime for purple to pink blossoms or Holly-tone and holly for blue flowers when fertilizing your Endless Summer Hydrangeas in the spring.
We advise fertilizing in April, May, and June with 1 cup of fertilizer for every foot of branch spread for the optimum flowering. For instance, 9 cups of fertilizer would be applied over a three-month period to a plant that is 3 feet broad. After this time, fertilizer shouldn’t be used to plants.
Continual Summer Fall is not the time to prune hydrangeas. Rather, only prune them in May. This will guarantee that the flower buds that survived the winter have opened.
Plants marked with a number sign (#) and a number are generally the same size as gallon pots; for example, #2 is equivalent to a 2 gallon pot, #3 to a 3 gallon pot, and so on. These plants are offered for sale in pots.
Plants with a height (such as 5-6′) give an estimate of the plant’s present height.
Plants that are measured in inches (such as 2.5″) are identified by their caliper, or trunk width.
Plants are typically larger when measured by caliper (inches) than when assessed by height (feet).
How are Endless Summer hydrangeas prepared for the winter?
The first hydrangeas to bloom on new growth and have the capacity to rebloom all summer long are called “Endless Summer” varieties. This unusual plant will need special maintenance.
Follow these suggestions if you’ve introduced one of these wonderful plants to your landscape to ensure that “Endless Summer” remains the highlight of your yard for many years to come.
The following is advised to ensure overwintering success in the first year:
- After August 15th, cease all fertilizer applications in order to prepare the plant for winter.
- Till the ground freezes in the fall, keep the soil moist.
- Apply a four-inch layer of organic mulch over the plant (wood mulch, leaves, etc.). It is not necessary to trim back or cover all stems all the way to the tip.
When entirely dormant (about November 30), or at the same time as you cover perennials in your garden, covering should be done.
- When the ground is no longer frozen in the spring, you should re-plant your perennials. The plant will expand from its root system and any old branches that made it through the winter.
- Be tolerant. Up until the late spring heat spurs the plant to develop rapidly, growth will be gradual.
- The old branches can be cut back to a finger’s width above the fresh, green growth once you notice it.
- Watch your plant develop and blossom while you relax; depending on your environment, this should happen around the middle of July.
The Endless Summer Hydrangea is quite tolerant and won’t suffer from being neglected or clipped improperly. In actuality, it’s preferable to leave young, recently planted bushes alone. Your Endless Summer will bloom on both old and new wood, unlike other hydrangea varieties (branches that grew last year and new branches from this year).
The fact that this hydrangea will continue to form buds and bloom throughout the season is another distinctive quality; deadheading the spent flowers will promote this. You won’t harm the plant by cutting the blooms; in fact, you’ll stimulate the plant to produce more blossoms. Feel free to dry or utilize the blooms fresh cut in vases. The optimal time to prune is in the spring.
Should the fall be the time to prune hydrangeas?
When do you prune? Only prune these hydrangeas in the summer after bloom, not in the fall. In August and September, old wood hydrangeas begin to form their bloom buds for the following year. If you don’t prune your hydrangeas real soon, then it is better to wait until next year.
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.
On new or old wood, do Endless Summer Hydrangeas bloom?
Old wood is the growth of a plant from an earlier growing season. Endless Summer hydrangeas produce big, numerous, lovely blooms year after year by blooming on both old and new wood.
How are hydrangeas prepared for the winter?
Protecting flower buds is the aim of winter hydrangea care. The simplest approach is to pile 12 inches or so of mulch made of chopped-up leaves or bark around the base of the plant. After the ground freezes in the late fall, set the mulch pile there. Plants can then be exposed in the spring, when the temperature starts to stay above freezing.
Should you deadhead Endless Summer hydrangeas?
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.
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.

Why aren’t the hydrangeas in my Endless Summer garden 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.
For the winter, should I wrap my hydrangea?
Here is professional guidance on how to put hydrangeas to bed for the winter season from guest bloggers Megan Nichols and Jessie Jacobson of Tonkadale Greenhouse in Minnetonka, Minnesota. (They may have more hydrangea trees and shrubs in their zip code than almost anywhere else in the United States, so they are aware!)
The temperature has dropped, and autumnal symbols can be seen everywhere. The garden needs to be put to bed soon. Hydrangeas reward us with large, stunning, and prodigious blooms all season long. You may say that they are givers. It’s time to return the favor now. It’s time to tuck the hydrangeas in with kisses and wishes for sweaty dreams.
Here in Minnesota, our moods can fluctuate as drastically as the unpredictably harsh winter weather extremes, snowfall, and freeze/thaw cycles. Despite the fact that many hydrangeas are regarded as hardy, all of this can confuse them. To survive the winter and come back bigger and better the next year, they require some care. Although hydrangeas cultivated in warmer areas don’t need as much post-season primping as those grown in our zone, there isn’t a single thing that wouldn’t appreciate a little tender loving care right now.
Utilize these suggestions to get the most out of your hydrangeas so that you can be the one to present at this time next season!
(Is pruning in order? No and yes. Here is our recommendation for which hydrangeas should be pruned right away and which should wait until spring.)
Don’t Stop Watering
Make a commitment! I shall water my hydrangeas till the earth freezes solid, you declare while raising your right hand. really good Hydrangeas are thirsty plants by nature, so it’s essential to give them regular, deep watering. We don’t need to get all linguistically nerdy right now, but their name literally means “hydration.” Winter’s cool, dry winds completely drain the moisture from the vegetation, and hydrangeas don’t use lip balm. It need not be heated in order to be dry!
If a freeze is not a concern where you live, water deeply but sparingly during the winter depending on how much rain you get.
This is how: Making a small hole in the side of a 5-gallon bucket, filling it with water, and placing it at the base of the plant while it slowly drips out of the bucket is one method. Another option is to lay your hose at the base of the plant for about an hour with the water turned on to a gentle drip.
Give Them One Last Hearty Meal
Composting your hydrangea beds in the fall will give them a boost for the upcoming growing season. Everyone feels better after a full night’s sleep and a filling breakfast. This also applies to hydrangeas. After a lengthy winter’s hibernation, they will be ravenous for some nice compost. Compost can decompose during the winter if it is used now, making nutrients easily accessible in spring. A few inches of compost is advisable even in regions without a deep cold. Only compost is being discussed here! Don’t give your hydrangeas fertilizers that are high in nitrogen because this can encourage them to produce new foliage growth.
This is how: Before laying down mulch in colder climates, top dress the area with compost, well-aged manure, or other organic material after the ground has frozen. This organic fertilizer, which is rich in nutrients, will decompose over the winter, making nutrients available to the plant in the spring. Apply compost in the late fall or early winter in zones that are warmer.
Mulch Matters
Mulching helps keep moisture in and weeds out in warmer climates while shielding the crown and roots of your hydrangeas from harsh winter temperatures in colder climates. Snow serves as a natural insulator if everything goes as it should. Plants suffer during strange winters with little snowfall and extreme temperature changes. Apply a thick layer of mulch around the plant’s base to offer hydrangeas the best chance of flourishing. While decorative mulch is useful, straw, marsh hay, or dead leaves are suggested instead.
This is how: Apply a 6–8 layer of mulch once the ground has frozen (or late fall or early winter in zones with milder winters). This shields plants from the heave-ho of springtime freeze/thaw cycles, which can yank them out of the ground. Inviting mice to make this their snug winter home, causing rotting and illness, or tricking the plant into believing it’s time to bud, are all consequences of mulching too early. Be patient; you don’t have to do things early simply because your neighbors are.
Keep Them Cozy
The amount of winter cold determines whether or not hydrangeas require protection. Winter protection is not required in zone 7 if the air temperature stays above zero degrees. Wrap or totally cover barely hardy hydrangeas in chilly areas. This is crucial for plants that bloom on old wood, such hydrangeas with mop heads and large leaves (Hydrangea macrophylla). The most recent types of mop head/big leaf hydrangeas, however, bloom on both fresh and old wood, so it’s important to keep that in mind. In their favor and ours! Hardier hydrangea varieties like the paniculata and arborescens don’t often require additional winter care, although really low temperatures might cause its limbs to die back. Consider covering if a colder than usual winter is forecast.
This is how: Wrap plants loosely in a few layers of burlap, making sure to tie it off with strong twine. Making a mulch mountain and covering the majority of the plant is an additional choice. Smaller, newly planted specimens respond well to this technique.
There’s Still Time To Plant!
The first three varieties of hydrangeas can be grown here in Zone 4; oak leaf hydrangeas can also be grown in warmer climates (zones 5 to 9). The optimal time to plant shrubs is in the fall. Just make sure to do all of the aforementioned things, including watering and mulching.
Here are some of our favorites that you can plant now for stunning blooms the following spring.
Panicle Hydrangeas
These late blooming hydrangeas, sometimes known as PeeGee hydrangeas (summer into early fall). They are covered in elongated, conical flower heads that emerge white or green and blush into pinks and peaches as the season goes on.
