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.
Can you restore hydrangeas?
Because of their thick, woody branches and sticky sap production, hydrangeas are sometimes among the first flowers in an arrangement to begin to appear dejected. This is because it might be difficult for hydrangeas to absorb enough moisture in a vase to cover the entire flower. But since hydrangeas are one of the few plants that can absorb moisture through their florets, completely soaking wilting blooms in water and letting them sit for a few hours to rehydrate will revive them.
If you have a few stems of cut hydrangeas that you’re not quite ready to throw away yet, it might be worth a try to revive them. The efficacy of this hack, according to Seattle-based floral designer Rizanio Reyes, “depends on when the flowers were cut and how long they’ve been in a box in cold storage post-harvest,” among other things. Freshly cut, somewhat wilted hydrangeas will probably be easier to revive than ones that have been in storage for a while (though it’s still worth a shot!). According to Reyes, “I’ve done this with some degree of success, but it’s never 100%,”
Avoid the temptation to use this method to save other popular cut flowers from withering, such as roses, peonies, or tulips. Soaking them will just hasten their decay and wilting because they lack hydrangeas’ capacity to absorb moisture through the blossoms.
Why does my hydrangea seem to be going out of style?
When a hydrangea dies, it is typically because the soil is too dry or it is exposed to too much sunshine, which causes the leaves to wilt and turn brown. Frost damage can easily affect springtime new development, turning the leaves and flower buds dark and mushy and giving them a dead aspect.
Here is a reference table listing the symptoms and most frequent causes of hydrangea death:

Trick No. 1: Give Them a Soak
At Ardelia Farm & Co. in Irasburg, Vermont, Bailey Hale, co-owner and manager of floral operations, was our source. His suggestion to revive faded hydrangea blooms? He advises to soak the blossoms in warm to warmish water for 30 to 40 minutes.
Why? According to Hale, hydrangeas absorb water through both the stems and the flower petals. Your cut hydrangea will receive plenty of water and have an opportunity to rehydrate by being submerged.
Trick No. 2: Cut the Stems
Hale also suggests trimming the stems. Many people are aware that giving flower stems a fresh trim will prolong the life of bouquets, but Hale claims there is more to it than that: “It is more difficult for water to reach the blooms on stems that are longer.
To further aid the stem’s ability to absorb water, shorten the stems and then cut a crisscross pattern into them. In contrast to what is commonly advised for flowers with woodier stems, such as lilacs, he does not advise breaking the stems. “If the stems are broken, the vascular tissues that absorb water would be harmed, he claims.
Trick No. 3: Use Boiling Water
When hydrangeas are clipped, a sort of sap is produced on the severed stems, which can stop the water from reaching the flowers and make them droop. Water should be heated in a kettle and brought to a boil. Fill the container with the boiled water. Your arrangement should be emptied of the wilting hydrangeas, and the stems should be recut at a 45-degree angle. The stem should be held erect in the boiling water for around 60 seconds after being incisionally made with a vertical slit. The hydrangeas should bloom again in about an hour if you put them back in your floral arrangement.
Do I need to prune my withering hydrangea?
Remove up to one-third of the older living stems from the hydrangea each summer, cutting them all the way to the ground. The plant will recover as a result. Before the end of July, if required, prune back the plant to regulate its growth and give the buds time to grow. Usually, the plant grows back to its previous size right away.
Dormant or dead, my hydrangea?
That mass of hydrangea sticks starts to produce new growth in the spring, either from the crown (or base) of the plant or from a cane. By about May, if you see no new growth at all, your plant may have suffered from “winter kill,” which was undoubtedly brought on by too-cold, freezing temperatures that were perhaps made worse by a drying wind.
The New York Botanical Garden’s Lorraine Ballato, a horticulture and educator, advises that you scratch some stems with your fingernail to be certain. A stem will show some green under the bark if it is alive. By the end of spring, if you can’t discover any living stems and no sprouts are emerging from the plant’s base, your hydrangea is dead. Remove the plant and try a more tolerant of the cold kind.
But keep in mind that the USDA hardiness zones measure a plant’s capacity for merely surviving, or whether its roots can endure the winter. According to Ballato’s essay for the National Garden Bureau, when it comes to hydrangeas, you also need to know if the stems can endure as many hydrangea kinds only bloom on wood that is a year old. What’s the sense of having a hydrangea if you can’t obtain blooms? To be sure, she advises asking a nearby nursery or extension office about the varieties of hydrangea that do well in your area.
How may a hydrangea that is dying be revived?
When your plants aren’t feeling well, hydrangea droop is a common symptom of too much sun and insufficient water, making it a wonderful place to start. Use your finger to probe 1 to 2 inches (2.5–5 cm) beneath the soil’s surface to determine the moisture level of your hydrangea. If it seems dry, water thoroughly while squeezing the hose tightly around the plant’s base for several minutes. Every few days, check the moisture level and add water as needed. Add 2 to 4 inches (5-10 cm) of organic mulch around the base of the plant if this cheers it up to help keep the soil moist. It could be beneficial to offer a temporary sun shelter on particularly hot days during the warmest portion of the afternoon.
When excess nitrogen promotes quick, spindly growth, overfertilization may result in droopy flower heads. Large hydrangea flowers are difficult for these weak branches to support, so they frequently flop. Always do a soil test in the future before fertilizing; hydrangeas frequently receive an abundance of extra nutrients from lawn fertilizer run-off. If your plant’s nitrogen level is high, fertilizing with phosphorus and potassium could help it develop more uniformly.
Hydrangea cultivars that flop over at random are a regular occurrence. Sometimes they just fall over because they have heavy blossoms or have taken a lot of weather abuse. If it occurs every year, try thinnng the inside of your plant to encourage more vigorous development and removing around half the flower buds before the season begins. If this still isn’t enough, you could stake your hydrangea with peony stakes or tie the center supports to a strong metal stake or fence post to make it appear more upright.
Do I need to remove the Brown hydrangea leaves?
If newly emerging hydrangea leaves or flower buds are exposed to a late-spring frost or chilly winds, they will turn brown. A unexpected cold spell can harm the newly emerging buds and leaves, which are exceptionally delicate and susceptible to injury. This can cause the buds to turn brown and wither away.
Naturally, hydrangeas grow in protected regions under trees that block chilly winds and produce a more stable microclimate that allows the young flowers to open up without facing a serious risk of frost.
Hydrangeas’ newly formed buds and leaves can become mushy and their leaves can turn brown when they sustain frost damage.
Since it is more exposed to the environment, the outermost growth is typically the one that suffers from the worst damage.
Sadly, the harmed flower buds are therefore unable to bloom, and the freshly growing growth is probably not going to recover.
Frost damage to hydrangea flower buds and foliage is more common in exposed areas, so plant or move your hydrangea to a more protected area of the garden, close to your house, or close to some other plants and hedges.
Particularly hedgerows are great wind breakers since they shield your hydrangea from the elements and might lessen the effects of frost.
There isn’t much you can do to save flower buds or younger leaves after they turn brown. As a result, prune back to healthy growth any growth that has been harmed by the frost.
In contrast to the flower buds on the plant’s outermost part, which are naturally less protected, hydrangeas frequently have growing flower buds farther down each branch. These flower buds typically survive a frost.
This implies that your hydrangea can still bloom, but much later and with fewer flowers emerging. With a little patience, you should still be able to enjoy some lovely blooms throughout the Summer.
My hydrangeas are limp; why?
- If there is any standing water in the pot, remove it. The water typically remains underneath your pot if it has a coaster. We occasionally have a tendency to overwater the pot and neglect to fully drain them before setting them in place.
If the pot doesn’t have any holes, you can carefully tip it upside down to let the extra water drain.
Just watch out not to harm the plant while doing it. Give the plant more sunlight so that the soil’s water will evaporate more quickly.
- Plant in a new pot. Sometimes getting rid of extra water is insufficient. To determine the true state of the roots buried beneath the dirt, you must dig farther.
Gently loosen the soil around the hydrangea in the pot before removing it. Look for any signs of damage at the roots.
Remove the rotting parts that have already begun to develop. As fresh media, use a soil that drains effectively.
- Keep the water off for a long time. There is no need to add additional water if there is already too much there. You can skip the other two if you’re already watering your hydrangea at least three times each week.
This will give the plant enough time to use the water that the earth has been holding for hydration. Before watering it one more, let it to totally dry.
Underwatering
Underwatering causes the hydrangeas to seem limp, similar to overwatering. The difference is that because of its dehydration, the plant feels crisp to the touch.
The cells will shrink if you do not water them enough because they will use up all the water that is stored in their vacuoles.
Lack of water will make it necessary for the roots to work harder to draw water from the soil.
Because of this, roots go through stress, which impairs their capacity to operate normally.
The plant limps and may even perish under conditions of extended dryness.
How to Fix Underwatered Hydrangea?
- Water content should rise over time. Your plant is continually undergoing a process of development and growth. You’ll undoubtedly run into problems if you continue to water your hydrangea in the same way that you did when it was younger.
Compared to other indoor plants, hydrangea require a little bit more water. Make sure the amount you give is appropriate for the demands of your plant.
- On days when it’s hotter, use more water. Naturally, plants have a greater thirst in hot weather than in cold weather. Keep in mind to provide more water as the hydrangea requests it. But make sure that the pot’s water drains completely.
Through transpiration, plants lose water. The rate of transpiration rises in a hot climate.
- Hydrate frequently. Setting up a routine to follow when watering the hydrangea is crucial. This will ensure that it gets the water it needs when it needs it.
Decide which days of the week you will empty the trash. This will also assist you in developing a watering schedule for your hydrangea. You won’t lose out that way.
