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 are my hydrangea’s flowers dying?
A hydrangea’s roots can be burned if too much fertilizer is used, which will likely result in the plant dying, turning brown, and drooping.
As such, hydrangeas are not heavy feeders and do not require annual feeding in the same manner as roses do, and doing so can actually be detrimental.
Hydrangeas frequently develop and flower to their full potential if they are planted in healthy soil or the soil has been modified with compost prior to planting.
The hydrangea should flourish if a 1-inch-thick layer of mulch is applied around it to assist retain moisture and supply nutrients to the soil (compost and leaf mould are ideal options).
Only in the following circumstances should fertilizer be used:
- Planting the hydrangea in sandy soil (which is nutrient poor).
- The hydrangea is in a pot or other container where the roots have used up all the nutrients in the soil.
In these two situations, it is recommended to use an all-purpose fertilizer with equal parts nitrogen, phosphorus, and potassium (NPK) that is applied once in the spring and is generally well-balanced.
The roots of your hydrangea can be burned by well-rotted manure, especially if it is added to the soil after planting. However, if the manure is made from poultry manure, it may contain a lot of nitrogen.
To prevent issues, I advise putting compost to the soil as a soil amendment (fresh manure is particularly harmful, always allow it to rot for a year or so before using manure on your garden).
If your hydrangea is exhibiting indications of stress as a result of being recently planted in soil that has been altered with manure, move it to a location with soil and compost, and it should recover.
Reduce the amount of fertilizer used and remove any discolored leaves or blossoms. To assist the hydrangea recover, thoroughly water it in an effort to dilute the soil’s water-soluble nitrogen.
Key Takeaways:
- Most frequently, hydrangea deaths are caused by the soil’s lack of moisture. Because they need their soil to be continually moist, hydrangeas will droop or even die in a dry environment.
- Drought, transplant shock, frost damage, and too much sun can all cause hydrangeas to perish.
- If the pot base doesn’t have drainage holes, potted hydrangeas may succumb to root rot. Small containers may dry out too rapidly and limit root expansion.
- Water hydrangeas liberally, cover them with compost mulch, and keep them out of the sun and wind to help them recover. To encourage healthy growth, remove any growth that has been sunburned or damaged by frost.
Should I remove the spring blooms of my brown hydrangea?
Pruning is not typically thought of as one of the many gardening activities that may be done in the fall, despite the fact that there are several. It can be difficult to cultivate hydrangeas successfully in New Hampshire, and if you want your plants to blossom, there is frequently very little room for error in pruning.
Wait until Spring to prune hydrangeas
In New Hampshire, hydrangeas come in a variety of kinds, and each one has quite distinct growth patterns and pruning needs. Some plants only produce flowers on fresh growth, while others mostly produce flower buds on older wood. In any case, it is better to postpone all hydrangea pruning until spring. Hydrangeas, as with all other trees and shrubs, go dormant in the fall. Not much new growth is produced by them until the next spring. As new growth is more vulnerable to harsh cold at the location of wounds, plants that have been trimmed now run a higher risk of winter damage. Additionally, fall pruning may lessen the quantity of June blooms.
Considerations for pruning hydrangea species commonly grown in New Hampshire gardens
The gigantic blue mopheads or lacecaps known as bigleaf hydrangeas (Hydrangea macrophylla), which are familiar to most gardeners, form their flower heads at the tips of stems on old wood from the previous year. Although lower buds along the stem have the capacity to grow blooms as well, the hydrangea’s blossoming potential is decreased if those buds are died or damaged throughout the winter. Wait until new growth sprouts in the spring before pruning your bigleaf hydrangeas. Approximately 1/4 inch above the first group of live buds, prune the plant. A hint: the interior of living stems will be green, whereas the interior of dead stems will be brown. Cut completely dead stems flush with the base.
The three other hydrangea species that are frequently planted in Fresh Hampshire—oakleaf (H. quercifolia), panicle (H. paniculata), and smooth—all bloom on new growth. Before the emergence of the leaves in the late winter and early spring, remove wasted flowers and prune the plant to improve its general structure and habit.
In conclusion, there are a ton of other activities you can engage in to stay occupied in the garden during fall. Save the spring for hydrangea pruning.
How can I maintain the color of a white hydrangea?
A lot of people are drawn to hydrangeas because of their vivid and exquisite colors. Several of them even alter their color! It’s no surprise that they’re so well-liked with their enormous blossoms and large, glossy green leaves. Don’t let that deceive you, though; adding a stylish white Hydrangea plant to your yard is just as attractive.
Focus on maintaining the health of your white hydrangeas by giving them the right amount of water, light, and fertilizer. If your white Hydrangea is becoming blue or pink, you definitely don’t have a true white variety because white Hydrangeas don’t change color with soil pH like blue and pink blooms do.
Should hydrangea blossoms be deadheaded?
Because hydrangea blossoms are so large, deadheading a hydrangea can help the plant focus energy on other, more crucial aspects of its growth. To promote new blossoms and keep your plant appearing healthy, you should continue this approach throughout the flowering season. The time of year determines the best way to deadhead hydrangea blossoms.
You should cut the wasted blossoms with a long stem still attached if it’s before August. Look at the stem’s junction with the larger branch; there ought to be several little buds there. Make sure to keep the buds whole when trimming the stem back as short as you wish.
The plant is probably developing new buds along the stems in anticipation of the following spring if it is August or later. Check the area between each set of leaves as you work your way down the stem from the faded bloom. You should see buds at the first or second pair of leaves. Offset the spent bloom far above those buds with a knife.
Carry a cloth that has been dipped in denatured alcohol while you work. To stop disease from spreading throughout the bush, wipe your pruners clean with the rag in between cuts.
How frequently should hydrangeas be watered?
Although the hydrangea’s leaves and flowers seem delicate, little careful care is actually needed for them. Everything you need to know about caring for hydrangeas is provided in these recommendations.
- Over the course of the growing season, water at a rate of 1 inch per week. To promote root growth, deeply water three times each week. All varieties of hydrangeas benefit from constant moisture, but bigleaf and smooth hydrangeas need more water. To water thoroughly while keeping moisture off the flowers and leaves, use a soaker hose. Hydrangeas won’t wilt as much if they are watered early in the day on hot days.
- To keep the soil around your hydrangeas cool and moist, add mulch. Over time, an organic mulch decomposes, supplying nutrients and enhancing soil texture.
- Apply fertilizer according to the type of hydrangeas you have. Every variety has varied requirements and will profit from applying fertilizer at various times. A soil test is the most effective tool for determining your fertility requirements.
- In March, May, and June, bigleaf hydrangeas require numerous mild fertilizer applications.
- Two applications in April and June work best for oakleaf and panicle hydrangeas.
- The only time smooth hydrangea plants require fertilizing is in the late winter.
- By selecting cultivars with resistant characteristics, you can avoid pests and diseases. Hydrangeas can have leaf spots, bight, wilt, and powdery mildew. Although they are uncommon on hydrangeas, pests might arise when the plants are under stress. Aphids, leaf tiers, and red spider mites are examples of potential pests. Your best line of defense is to properly care for hydrangeas.
How can I tell if I’ve overwatered my hydrangeas?
The leaves of an overwatered hydrangea may discolor and possibly drop off too soon. Additionally, it will produce fewer and irregularly shaped buds and blooms. Additionally, a hydrangea will develop discolored, withered leaves under extreme overwatering situations.
When should dead hydrangea blossoms be removed?
These are your macrophylla hydrangeas, also known as mophead and lacecap, which come in purple, pink, and blue. They also include hydrangeas with oak-shaped leaves. While reblooming kinds flower twice, some cultivars only bloom once per season on stems from the previous year (old wood).
The initial set of hydrangea blossoms should be deadheaded as soon as they start to turn brown and dry. Cut the stem immediately above the first set of leaves and below the flower head. When this second set starts to fade, you can deadhead once again for reblooming varieties, but only until about mid-August. Your hydrangeas will then produce buds for the flowers of the next year; you don’t want to unintentionally cut these off. After the summer has ended, dried flower heads can remain on the shrubs to add visual interest over the winter.
How are hydrangeas revived?
Greek words “hydor,” which means “water,” and “angos,” which means jar or vessel, combine to form the term “hydrangea.” Translation: a barrel of water! These lovely flowers that resemble pom poms require water to survive, and if they don’t get it, they wilt.
The woody stem of hydrangeas can make it challenging for the flower to obtain the water it requires. A small slice cut into the stem and an angled trim with a sharp knife help the plant absorb more water.
I used to use scissors to trim the ends of my flowers, but I’ve since moved to using a sharp knife on the advice of my friends at Byland’s. Apparently, using scissors causes the stems to be pinched, harming them and limiting their ability to absorb water.
While they were beautiful to look at when we originally built the floral arrangement for our Mother’s Day Frache Table, it didn’t take long for them to start to look very melancholy. I was able to keep them from being thrown away thanks to this simple approach, and the flowers still looked new and fresh!
Keep in mind that hydrangeas might wilt to a certain extent after which they cannot recover. The good news is that this hack is really easy to use and doesn’t call for anything complicated, so why not give it a shot?
Directions:
- A kettle or pot of water should be heated up and then left to cool gradually. It ought to be really hot right now. Fill the vase with water.
- Cut the ends of the hydrangeas at a 45-degree angle with the sharp knife after setting them on the cutting board. Then, on the newly trimmed stem, make a tiny vertical slit running up the middle.

Can hydrangeas be kept in pots?
Do hydrangeas thrive in containers? Given that potted hydrangeas received as gifts rarely survive longer than a few weeks, it’s a reasonable question. The good news is that they can, given the proper treatment. Growing hydrangeas in pots is a great idea because they can grow to be fairly large and have beautiful blossoms all summer long. Learn more about container-grown hydrangea plants and how to take care of hydrangea in pots by reading on.
Are white hydrangeas shade-loving?
In contrast, hydrangeas are a plant. Most thrive better in mild shade than in full sun, and they flower for months as opposed to just a few short weeks.
Hydrangeas enjoy water, as their name suggests. They thrive in clay and damp soils, but some of them seem to be able to adapt to considerably drier environments, especially if they are not exposed to intense sunlight. They are therefore most suited for growing in the mild shade of deciduous trees, where the soil is likely to be rich in organic matter from leaf fall.
The most practical Hydrangea paniculata cultivars bloom from mid-summer through to October, depending on the variety. Conical flower heads come in a variety of shapes and sizes, from robust panicles of sizable sterile florets to lacy mingles of tiny beaded fertile flowers. Throughout the winter, both can still be beautiful as they transform into parchment. Late winter pruning encourages robust, upright shoots; each year, trim down to a solid structure.
When planted with dark evergreens like Viburnum davidii and Aucuba japonica ‘Rozannie,’ Hydrangea paniculata is especially beneficial. Use a variegated Euonymus fortunei ‘Emerald Gaiety’ as an underplant. Perfect for adding color to a dark bed or border.
One of the most well-known hydrangeas is Hydrangea arborescens ‘Annabelle’. In the latter half of summer, it’s impossible to ignore the enormous, sponge-like white flowerheads and soft green foliage. It looks great with silvery miscanthus and dark sarcococcas beneath white-barked birches. Plant it where it can rely on the support of neighboring plants because the weight of the flowerheads can cause the stems to sag and flop. Although there are differing views on how severe to prune, there is little question that it needs to be trimmed down in the late winter to a few centimeters from the ground level. Excellent on chalk and wonderful for filling a shadowy corner.
The architectural foliage of the oak-leaved hydrangea, Hydrangea quercifolia, is nearly as prized as its floral blooms. It is never among the most well-liked because of its habit, which may be somewhat awkward. The foliage in the fall develops deep colours in areas where it receives a sufficient amount of sunlight. The foliage are a rich green color in the shade. Similar to Hydrangea paniculata flower heads, although frequently more pendant. One of the most impressive varieties is Hydrangea quercifolia “Snowflake,” which has enormous sprays of double, creamy-white flowers.
The less common Hydrangea macrophylla has coarser stems and smaller leaves than the Hydrangea serrata.
The former has huge leaves and blooms, but the latter has little, delicate lacecap flower heads that appear to be more drought resistant than the bigger growing variants.
One well-known variety of free-flowering hydrangea serrata is called “Bluebird.” The delicate blooms are gentian blue in acidic soil and mauve-pink in alkaline soil. From late summer on, the leaf is flushed with plum purple, even in the shade.
Numerous Hydrangea macrophylla cultivars with pink and red flowers will “blue” in acidic soil. If your soil has a higher pH, you can cultivate blue blossoms by planting them in a pot of ericaceous compost and regularly spraying them with hydrangea colorant. Although the purple-pink blossoms are equally lovely, for some reason blue hydrangeas are always more sought-after.
There are two different blossom shapes in hydrangea macrophylla variants. Some plants are referred to as mopheads; these are the ones with enormous, sterile florets in their bold, massive heads. The lace-cap hydrangeas are the other species. These feature heads with tiny, fertile florets that are encircled by bigger, sterile florets. Pollinators are drawn to the lacecaps more. The gorgeous lacecap hydrangea Hydrangea macrophylla ‘Zorro’ has black stems and blooms that become vibrant blue in acidic soil, even in partial shade.
Varieties of Hydrangea macrophylla with white flowers never change color in response to soil type.
However, they may turn pink or even deep blue when exposed to the light or when the weather is bad. One of the best white mophead hydrangeas is Hydrangea macrophylla ‘Madame Emile Moulliere, which when grown in the sun has reddish tinges along the edges of the florets; in contrast, when planted in the shade, the flowers are completely white.
Secrets of success
Even while some of these hydrangea cultivars can withstand drought better over time, newly planted plants still require frequent watering to thrive.
Despite being very resilient, hydrangeas are susceptible to frost damage as the spring season begins. Avoid placing them in areas where this might be a problem. In general, Hydrangea paniculata is more resilient to spring frosts.
Every year, fertilize hydrangeas using a slow-release fertilizer meant for flowering plants. Potash-rich fertilizers aid in hardening the growth and promoting blossom production.
