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.
When may I remove the hydrangea’s dead blooms?
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.
What happens to hydrangeas if I don’t deadhead them?
Deadheading too-tall hydrangeas can occasionally be challenging. Your other option is to keep them on if you don’t have the skills to reach spent flowers or all of the spent blooms. And you can do that without suffering too much harm.
Simply omit deadheading hydrangeas, and your plant won’t suffer. At least nothing major enough to need worrying about.
Your hydrangea might not produce as many or as large of blooms as it would have if the spent blooms had been removed. It will nevertheless continue to bloom.
Having said that, you can think about pruning hydrangeas that have gotten too tall in order to make them smaller and easier to handle.
This will make it simpler for you to maintain the tidy appearance of your hydrangeas. Additionally, it will make it simpler to remove spent blooms from plants and promote future blooms with greater vigor.

Not a Spot! Hydrangea leaves get unattractive, black stains when it rains unusually much (or if you overwater them). This Cercospora leaf fungus is relatively innocuous despite its frightening name. Remove badly impacted foliage and leaves with spots to stop the fungus from spreading.
Will to Wilt 2. Are the hydrangea blossoms withering or drooping? Your plant is most likely receiving insufficient water and too much light. Verify that the soil is moist one to two feet down. If not, deeply spritz. Repeat weekly for optimum hydrangea care. Mulch can also help you save water, so add some. If that isn’t the case, perform a soil test to determine the nitrogen levels in your soil. Make the necessary changes.
Three. Brown Blooms Your hydrangea blooms may need extra water if they are prematurely turning brown and fading away. The same applies if your flowers start to wilt during the day and don’t recover at night. Look for brown stains on the leaf edges to confirm. Once a week, deeply water hydrangeas to mend.
4. Holy Grail Foliage. Hydrangea leaves have holes chewed through by fruit bugs and slugs. Open a holey leaf. A fruit worm is what you should locate if it resembles a caterpillar. Utilize soapy water to get rid of them. Slugs are probably responsible if nothing is found. They can be hand-selected at night or given a nightcap. Bury a plastic cup so that the rim is level with the ground next to the hydrangea. Then pour half a beer into the cup.
Blooms Be Gone, No. 5. Your hydrangea is barren of blossoms. You probably pruned your hydrangea at the incorrect time, removing all of its fresh blossoms. Instead of trimming hydrangeas this year, read our hydrangea pruning recommendations to ensure that you never prune them at the incorrect time again.
Purple Pout, 6. Remove the leaves and branches that have the purple stains from your leaves. You may not have enough phosphorus in your soil if the entire leaf is purple. Test your soil, and adjust as necessary.
Abracadabra! Your hydrangea issues will shortly be resolved. Then, you can concentrate on all the wonderful aspects of cultivating hydrangeas, such as enjoying their enormous, fluffy blossoms.

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.
Should I prune my hydrangea’s dead heads?
Correctly and timely deadheading your hydrangeas only benefits these plants in the long run. Deadheading is the technique of removing wasted flowers from a plant to promote greater blooming later on, much like trimming. Professional gardener Melinda Myers notes that deadheading encourages the plant’s energy to flow into the leaves, stems, and roots (rather than developing seeds) for future growth.
According to Myers, deadheading your hydrangeas provides cosmetic advantages in addition to enhancing the future blooms. She says that many gardeners prefer the neat and tidy impression that faded blooms create to that of dried flowers left on the plant. The species of your hydrangeas will determine when and how to deadhead them, according to Myers. Here is her response to our question regarding the ideal moment and technique for harvesting finished flowers from several varieties of hydrangeas.
Do I need to remove the dead stems from my hydrangea?
Remove stems that are crossing or dead. Cut these stems just above the soil line. Keep in mind that old wood is where buds for blooms are generated, thus the more old wood you remove, the less blossoms will appear in the spring and summer. Remove up to one-third of the older living stems from the hydrangea each summer, cutting them all the way to the ground.
Why are the flowers on my hydrangeas 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.
How should a flower be deadheaded?
Flower deadheading is quite easy to do. Pinch or remove the flower stem as plants stop blooming when it is below the spent flower and just above the first set of lush, healthy leaves. Repeat with all of the plant’s dead blooms.
Sometimes completely cutting back plants makes it easier to deadhead them. Remove the wasted flowers by shearing off the top few inches (5 to 10 cm) of the plant. Prior to shearing the plant’s top, always carefully inspect plants to make sure that no flower buds are concealed among the wilted blooms. Cut the stem immediately above any fresh buds you may discover.
Make a point of deadheading frequently and early. Deadheading will be considerably simpler if you spend at least a little time each day in the garden. Start early, in the late April when few plants still have their faded blossoms. Deadheading flowers is a tedious task, but it will get easier if you do it a few days a week. However, the unpleasant process of deadheading will be understandably overwhelming if you decide to wait until later in the season, such as early October.
Nothing makes a gardener more than seeing their work come to life with stunning blossoms, and if you practice deadheading throughout the growing season, nature will reward you with a second wave of blooms to appreciate even more.
