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 should I prune my hydrangea’s dead flowers?
Myers asserts that how you deadhead your hydrangeas is just as crucial as when you do it. Make your incision directly above the first set of full-sized leaves, which should be situated beneath the blossom, she instructs. “You are essentially eliminating the faded blossoms to expose a set of sound leaves. This can be carried out immediately following flowering, in late winter or early spring.”
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.
Should I remove the hydrangea bush’s dead blooms?
When should I prune my hydrangeas? is one of the most often asked gardening topics. We all have a tendency to want to hurry outside with the clippers and start hacking away when those billowy large flowers change from cheerful blues, purples, pinks, reds, and whites to uninteresting browns.
When to Cut Back Hydrangeas
The timing will vary according on the variety of hydrangea you have. First of all, be aware that hydrangeas do not require pruning unless the shrub has become unruly or too big for its location and requires some shaping up. Otherwise, simply deadhead wasted blooms and remove any dead branches from the plant.
How to Prune Hydrangeas02:07
But if you do decide to prune one, bear in mind to time it so that it blooms on old wood or new wood depending on the species of hydrangea you have.
If you wait too long, you can chop off the buds that are developing on old wood (stems from the year before the current summer), which would prevent flowers from blooming the following spring. Therefore, as soon as the flowers on these bushes have faded, they should be clipped.
The shrub should be clipped in the early spring before that new growth appears, but, if the shrub flowers on fresh wood (stems generated during the current season), which means that its buds are set inside the season.
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 are hydrangeas kept from blooming?

How do you prevent hydrangeas from turning brown?
Because the hydrangea is losing more water from the leaves than it can store at the roots, the foliage and blooms of hydrangeas turn brown. As an indication of stress, hydrangea leaves and blooms turn brown and wilt if the soil around the roots is not continuously moist.
Even when the soil is moist around the roots, excessive wind also removes so much moisture from the enormous surface area of the leaves. Because the roots are unable to quickly draw up and replace the water lost from the leaves, the hydrangea leaves and flowers may still turn brown and curl.
Your hydrangea’s leaves may turn brown and wilt if it is in dry, sandy, or stony soil because water drains too quickly for the roots to draw up the moisture it needs.
Hydrangeas should be watered (with a thorough watering) as often as necessary so that the soil is moist. However, there is no universally specified guidance for watering hydrangeas because it depends on climate, weather, and factors like the maturity of the hydrangea plant.
You might need to water your hydrangea almost daily during the hottest months of the year (especially if it is in a pot).
It is necessary to recreate the conditions of the hydrangea’s native environment in order to revive hydrangeas with brown leaves and flowers. To do this, plant hydrangeas in soil that retains moisture, water them as often as necessary to keep the soil moist, and protect them from wind, which depletes moisture.
- The best place to plant or transplant hydrangeas is in soil that has been supplemented with organic matter (compost, leaf mold, or well-rotted manure) to a depth of 18 inches, which is deep enough to accommodate the hydrangea’s root system once it is grown. This makes hydrangeas more drought-resistant and lessens the possibility of browning foliage and blossoms.
- Since hydrangea roots are broad, it is crucial to thoroughly water the area around your plant if replanting is not an option. Ideally, use a hose to ensure that the soil is evenly moist to a good depth.
- Always soak the hydrangea deeply since this promotes the roots to expand deeper into the soil to obtain the moisture, increasing its drought resilience. A hydrangea’s roots become fragile in the summer and are more likely to turn brown if they receive too little water, which causes them to grow close to the surface.
- Mulch (compost, leaf mold, or well-rotted manure) should be applied to the soil’s surface surrounding your hydrangea in a 2 inch depth. The mulch aids in maintaining the soil’s moisture to achieve the ideal moisture balance.
- Make sure your hydrangea is not in the path of the wind since it dehydrates the leaves and turns the blossoms brown. Planting hydrangea under a tree is a good way to increase shelter and create the ideal environment because hydrangea naturally grow in woodlands. The hydrangea can be moved to a more protected section of the garden or additional cover can be created with other plants to block the wind.
Anytime of year, you can use pruners to trim back any brown leaves and blooms, or you can just wait for them to fall naturally.
The growth from which the blooms are exhibited can be removed by excessive trimming, so it is necessary to stress that mild pruning is preferable.
I should also stress the value of routine watering and the use of mulch.
In order to replicate the moisture-retentive soils to which hydrangeas are suited, a coating of leaf mold or compost can really help. Hydrangeas naturally have a mulch of fallen leaves on the wood land floor every year that helps conserve moisture.
The leaves should stay green once the hydrangea has established in its ideal environment, but the flowers typically do not return, so you might have to wait until the following year before they blossom.
How can a brown hydrangea be revived?
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.
