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.
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).
Are your Endless Summer hydrangeas pruned down for the winter?
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.
How may hydrangeas be best protected from the winter?
Stakes can be used to create a frame around the plant to protect it throughout the winter. To create a cage, encircle the stakes with chicken wire. Pine needles and/or leaves should be stuffed inside the cage to completely insulate your plant.
Because they do not settle as quickly as other materials, oak leaves perform nicely. As the insulation settles during the winter, keep a bag of leaves from your fall leaf raking pile to fill the cage.
As you fill the cage, take care not to snap off the ends of the branches because if you do, it will all be for nothing and you won’t have those magnificent blossoms the next summer.
Are hydrangeas Endless Summer immune to frost?
Based on the lowest winter temperatures, the USDA Hardiness Zones show the areas in which plants can grow. In contrast to other hydrangea kinds, Endless Summer Hydrangeas can grow in Zones 4 through 8, making them more adaptable. They can handle mild heat and are able to withstand extreme cold. However, they should only get a little afternoon sun in warmer climates.
What are hydrangeas used for in the winter?
One of the most adored Southern belles in the garden is the hydrangea. There are many reasons to enjoy shrubs; they tolerate shade, come in a range of colors, and can add interest all year long. In addition, hydrangeas typically require little maintenance and thrive in challenging growth environments.
Hydrangeas in Winter
Mulch over the hydrangeas in the winter to protect them. Leave faded blossoms alone to add interest in winter.
You may be wondering how to ensure that your shrubs remain secure over the winter due to the unpredictable nature of the weather. I am aware that I am in Georgia. So I asked Ryan McEnaney of Bailey Nurseries the most important winter care issues for hydrangeas, and fortunately, the answers are straightforward:
Is there a time or temperature when it’s “too late” to winterize hydrangeas?
Any form of protection is beneficial. Winter months bring a wide range of temperatures, so if you’ve already experienced any really chilly spells, some harm may have already been done. Despite this, continue to preserve it to ward off any potential threats in the months to come.
Will mulch prevent plants from heaving? Is there a type of mulch that is better for winterizing plants? When spring returns, do I need to remove the mulch?
Plants in the ground and in containers benefit greatly from mulch during the winter. Beyond providing general security, the mulch’s role is to establish an environment that is more consistent with what is going on outside. Temperatures can change from -10 to 30 degrees in some areas of the nation within a week or two. As a result, the root system is disrupted as water molecules in the ground freeze (contract) and then defrost (expand) (heaving). Mulch aids in minimizing those abrupt alterations to safeguard the plants. We advise using wood mulch, oak leaves, or pine straw.
To prevent damage from late spring, wait until after your last frost date to [remove to the mulch]. However, don’t wait too long as heat can develop moisture, which can cause the stems to rot in the absence of air flow.
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.
When ought my hydrangea to be covered?
The greatest places to grow hydrangeas are warm winters with few days below freezing. The plant needs protection to survive in the event of a freeze or if you are growing your hydrangea in a cooler area. Since hydrangeas develop their flower and leaf buds in the fall, freezing temperatures may cause the buds to die before they can bloom. In the end, the plant dies since there aren’t enough leaves to maintain it. The hydrangea can bloom every year if it is protected over the winter.
Before the ground freezes in the fall, spread a 4-inch layer of straw mulch all around the base of the hydrangea. Winter soil temperature is maintained by mulching, safeguarding hydrangea roots.

To completely round the hydrangea, cut a length of concrete reinforcing mesh. To create a cylinder, coil the mesh around the plant and use wire to join the mesh’s ends.
Straw, peat moss, or dried leaves should be used to completely cover the hydrangea in the mesh cylinder. Throughout the winter, as the straw or leaves settle, replace them to keep the plant always covered.
Early in the spring, about four weeks before the last anticipated spring frost, remove the mesh cylinder and straw. The mesh cylinder should be removed as soon as early spring bulbs like crocuses and tulips start to bloom.
After the mesh is taken off, if any freezing temperatures are anticipated, protect the hydrangea with a burlap bag. When the weather starts to warm up again, uncover the hydrangea.

- Straw, peat moss, or dried leaves should be used to completely cover the hydrangea in the mesh cylinder.
In regions where frost is a rarity, covering the hydrangea with a burlap bag only needs to be done on the days or nights when frost is expected, and then the burlap bag should be removed.
Even if they are sheltered, hydrangea flower buds may not survive in locations that frequently experience winter cold, but leave buds almost certainly will, preventing the shrub from dying.
How hot should I keep my hydrangeas covered?
When to Take Off the Cover. The following day, when it is at least 50 degrees Fahrenheit, remove the cover.
Should Endless Summer Hydrangeas be deadheaded?
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 called Endless Summer fail?
Published more than ten years ago, this article. Some information might not be up to date anymore.
The ‘Endless Summer’ Hydrangea bush I planted in a shaded area of my garden last summer disappointed me because the blooms fell over and didn’t really provide any color. However, they do create lovely cut flowers, so this spring I placed a second one in a gap next to the first. Even though it appears to be quite healthy, it has yet to bud. How come the second one wouldn’t blossom? And is there anything I can do to get the stems to stand up so I can see the flowers?
When they don’t receive enough light or moisture, hydrangeas flop over. Check this out first since if the plant is in a rain shadow or a shaded spot, you might not notice that it isn’t getting enough water. For the second plant, a lack of flowers could indicate that the buds were severely damaged by frost, that the grower overfertilized the plant to generate so many leaves, or that you may be crowding the plant. Generally speaking, “Endless Summer” need early sun and afternoon shade (because that’s when the sun is at its sweltering peak); you also can’t let it dry up or sit in water. Why not try moving both of your plants into more light, away from the roots and rain shadows, as a solution, and see if that improves the number of blossoms you get. Not yet, do not fertilize. In the late autumn, mulch well. In the spring, only remove the dead growth.
