I planted two hydrangeas in the fall, and as winter arrived they appear to have died. They have bare limbs and are brown-looking. What did I do wrong? I live in Zone 9.
Since the majority of hydrangeas are deciduous, it is common for plants to lose their leaves from late fall to early January. The buds should begin to swell and leaf out as soon as the springtime days begin to warm up.
It’s crucial to prune your hydrangeas as part of proper hydrangea care. Although you did not specify which variety of hydrangea you planted, the majority of the oak-leaf (H. quercifolia) and large-leaf (H. macrophylla) varieties bloom on growth produced the previous season. To avoid removing the growing flower buds for the following year, these kinds should be trimmed as soon as they have done blooming. Both H. arborescens and H. paniculata bloom on recent growth. They can be trimmed to the ground each year without causing any harm, and late winter or very early spring are the optimum times to prune them. I advise against pruning the bare, brown limbs this year. Decide whether the hydrangeas are flowering on the fresh wood from this year or the old wood from last year by carefully observing them. You can use this to decide when and how to prune them.

Why are my hydrangea’s leaves falling off?
Of course, the fact that the leaves are falling could be expected. Hydrangeas are deciduous plants, which means they lose their leaves every year.
This indicates that the loss of leaves by these plants at the end of winter is entirely typical. You’ll notice new leaves beginning to sprout as the first few days of spring arrive.
This information may already be known to you, but it’s still useful to know just in case. You might not have realized that hydrangeas are intended to lose their leaves at a specific period each year if you were worried about them.
The entire year, do hydrangeas retain their leaves?
No one! Because of this, a garden isn’t finished unless it has at least one hydrangea. These flowering shrubs are a constant delight with their lovely leaves and enchanted blossoms. Additionally, as long as you choose the appropriate variety for your environment, hydrangeas are simple to maintain.
In order to choose the hydrangea to cultivate, consider the following. On choose the best hydrangea variety for your yard, consult our guide to hydrangea varieties.
Hybridizing hydrangeas is simple! Find a hydrangea variety that will flourish in your garden by simply responding to these inquiries.
How much sunlight do hydrangeas require? The majority of hydrangea varieties prefer a morning blast of full light followed by an afternoon nap in the shade. Be cautious to verify though, as some hydrangeas do well in direct sunlight.
What shade of hydrangea would you like? Although hydrangea color may appear significant, it is not! Pink hydrangeas can be made from blue ones, and vice versa. Acidity of the soil affects the saturation and color of hydrangeas. The sole distinction? Hydrangeas that are white remain that hue.
3. What hydrangea size do you want? There are tiny, medium, and giant hydrangea varieties. Dwarf hydrangeas are only 3-5′ tall and wide, but larger kinds can reach heights of 20′ and widths of 18′. You may choose a hydrangea that works in any garden size, even container gardens.
4. Which hydrangea variety should I grow? Your hydrangea has to be clipped at various periods depending on the kind that you are growing. To make future trimming simple, make a note of the type of hydrangea you have. Bigleaf, oakleaf, panicle, and smooth hydrangeas are a few of the most popular varieties.
5. Is the hydrangea deciduous or evergreen? Hydrangeas with the moniker “evergreen” remain green all year long. Since the majority of hydrangeas are deciduous shrubs, they lose their leaves every year.
What should hydrangeas look like throughout the winter?
Throughout the summer, the enormous flower heads of hydrangea bushes (Hydrangea spp.) can cover a landscape with eye-catching flashes of blue, pink, or white. Most hydrangea cultivars, which are hardy in USDA zones 4 to 9, can survive a moderate winter without particular care, but they benefit from careful watering, pruning, fertilizing, mulching, and weathering over the chilly season for their spring growth and beauty. Winter doesn’t cover their stems, and if they aren’t clipped, old flower heads will turn brown.
Tip
If not removed, the dried and blackened flower heads of hydrangeas will stay that way all winter long. In the fall, hydrangeas likewise lose their leaves, but the brown stalks hold upright unless they are cut back.
Why are the leaves on my hydrangea yellowing and dropping off?
When in good health, hydrangea leaves are typically green, and the blossoms are eye-catching and vibrant. But when hydrangea leaves begin to turn yellow, isn’t it one of the telltale symptoms that something is wrong with this plant? What contributes to yellowing and how may it be treated?
Overwatering, excessive exposure to direct sunshine, or a lack of nutrients can cause hydrangea leaves to become yellow. Move the plant to a shaded location and drain the excess water from the pot to mend the yellow leaves. Feed the plant with an iron supplement and nitrogen fertilizer to maintain leaves green and healthy.
If you find a hardy type of hydrangea that can thrive in zones 3 and 8, and endure even some cold winter temperatures, hydrangeas are excellent plants.
Are hydrangeas winter-hardy?
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.
Should I trim my hydrangea to prepare for winter?
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.
