A dying hydrangea plant is frequently the result of dehydration, damage from frost, excessive sun exposure, or transplant shock. Make sure the soil is continually moist and offer protection from the midday sun to prevent hydrangeas from wilting and dying. It’s crucial to replicate some aspects of a dying hydrangea’s natural environment in your garden, with a focus on soil moisture and shelter from excessive sun and wind. The following are the main causes of hydrangea needing to be revived:
To learn how to fix these issues and rejuvenate your hydrangea so that it is strong and blooms the following year, keep reading. Hydrangea Drooping (Drought)
Because their roots are fibrous and somewhat shallow, hydrangeas need continually moist soil to flourish. The most prevalent cause of stress in hydrangeas—wilting or drooping—is drought or a lack of moisture in the soil. Typically, this is a result of the summer’s hot and dry weather, although there are other possible causes for the dry soil.
How to Revive a Drooping Hydrangea
It is crucial to provide these circumstances by properly preparing the soil and watering as needed in order for hydrangeas to thrive in constantly moist soil with plenty of organic matter. The ideal approach is to test the soil to a finger’s depth to see whether it is moist because the frequency of watering might depend on a variety of factors, including the climate and soil type. Give the soil a generous soak if it feels a little dry to help the roots take root. The aim is to maintain constant moisture in the soil (but not saturated). Instead of watering the hydrangea sparingly but frequently, which encourages the roots to grow close to the surface in search of water, you should always give it a deep bath. This makes the hydrangea more susceptible to drought. The majority of hydrangea species thrive in mild shade, with the ideal ratio of sun and shade frequently being provided by the dappled light of a tree canopy. Hydrangeas tend to dry out more quickly in full sun, which makes the plant droop. Therefore, choose your planting location wisely, or add some protection with other plants or trees, and water frequently to help the hydrangea recover from its drooping appearance.

Because they are naturally adapted to growing under tree canopies, hydrangeas thrive in gardens that provide some shade and wind shelter for the leaves. In full sun (more than six hours of direct sunlight), hydrangea leaves can frequently appear burned, turn a little yellow, and lose a lot of water through transpiration. Additionally, too much direct sunlight tends to dry out the soil, which makes the leaves and flowers of hydrangeas wilt. How to Tell If your Hydrangea is Sun-burntThe leaves of hydrangeas should appear the most damaged when exposed to direct sunlight, however those that are somewhat covered by other sections of the plant should retain a more vibrant green color, even though they may also be withering. While some hydrangeas can grow and bloom in complete darkness, most can thrive with a little amount of sun because it encourages blossoming in the summer. (Read my post, Why is my hydrangea not flowering? for more information on how to promote hydrangea flowers.) If your hydrangea is exposed to the sun for the majority of the day, you can either move it to a more shaded area of your yard or provide some shade with some other trees or plants. The plant as a whole should survive, but severely sunburned leaves are unlikely to recover. The hydrangea should recover if the shoots of the severely damaged leaves are removed to encourage new development. Why are my hydrangea blossoms turning green? (Read my article.) Hydrangea Leaves turn Brown or Black due to Frost DamageAlthough there are various reasons why hydrangea leaves can become black or brown, frost damage is to blame if the color has changed over night from a healthy green. The fresh, fragile growth that emerges in the Spring is most frequently damaged by frost, whereas the larger, more established leaves are frequently undamaged (as they are more hardy and acclimatised to cold weather). However, if the temperature drops significantly over night, frost damage could happen in the Fall. Fortunately, hydrangeas are tough plants; even though frost damage may appear severe, with a little tender loving care, the hydrangea can quickly recover. Frost can, however, harm the flower buds, which may prevent the plant from blooming. Revive Frost Damaged HydrangeasHydrangeas that have been severely damaged by frost can simply be revived by carefully pruning back any damaged growth with a pair of pruners at the shoots (avoid cutting back into wood). This will encourage fresh, healthy growth over the summer. After August, stay away from fertilizing hydrangeas as this frequently encourages new, tender growth when the hydrangeas should be hardening off to get ready for the chilly temperatures of Winter. Of fact, frost damage to your hydrangea’s budding flower buds can inhibit flowering. Since injured flower buds are less likely to bloom afterward, prevention is preferable to treatment. If you closely monitor your local weather prediction and there is a late spring frost, you should ideally cover the flower buds with horticultural fleece the night before to prevent damage from the frost. Frost damage is unlikely to harm your hydrangea, so it should recover with time and some gentle pruning, but it might not bloom fully until the following year.

After they have established themselves, hydrangeas are typically hardy, but they are more susceptible to dying during their first season. This can be a result of them adjusting to their new surroundings. When the conditions in your garden change significantly from the ones the plant was grown in (at the nursery or while on display in the garden center), transplant shock is more noticeable. The hydrangea can become quite used to these conditions if it has been carefully cultivated in a nursery greenhouse with the ideal and consistent temperature, fertilizers, water protection from wind and too much sun, etc. This makes the hydrangea less hardy when it is planted outdoors. Additionally, planting hydrangeas in the height of summer might be troublesome. The optimum season to plant hydrangeas is in the spring or fall since this provides the hydrangea time to establish its roots and adapt to the soil, allowing it to properly absorb moisture before the high summer heat. The hydrangea may dry out in the summer due to the increased temperatures, which prevents the roots from absorbing water at the same rate as it is lost through the huge, many leaves, causing the hydrangea to wilt and turn brown. How to Revive a Newly Planted Dying Hydrangea
Make sure the soil where your hydrangea is planted is appropriate. If they are planted in soil that is too sandy (drains too rapidly and is deficient in nutrients) or has too much clay, hydrangeas may not survive after being planted (soil drains too slowly and perhaps bakes hard in summer which makes it difficult for the roots to establish). In gardens with unfavorable soil conditions, it’s crucial to amend as much of an area as is practical (at least twice the size of the root ball) before planting your hydrangea in order to create the ideal soil conditions. Compost with multiple uses and leaf mold are great soil amendments for hydrangeas. Applying mulch on a regular basis each year also helps to maintain the soil’s favorable conditions for your hydrangea’s growth. Root Rot (Hydrangea Dying in a Pot or Boggy Soil)
Hydrangeas cannot withstand soggy soil; they need wet, well-draining soil. Root rot results from a soggy environment in the soil. Hydrangeas need soil that is both moist and quick to drain, which is a quality of loam soil, compost, and well-rotted organic material from garden waste. Your hydrangeas may suffer from fungal diseases like root rot if your soil is heavy clay or naturally soggy since it will drain too slowly for them. This also occurs when hydrangeas are planted in containers without adequate drainage holes in the base or when the drainage holes clog, making it difficult for excess water to escape effectively and leaving the soil too wet and humid for hydrangea growth. This encourages the growth of fungi that cause illnesses like root rot, which makes hydrangeas droop, develop brown or yellow leaves, and eventually die. How To Revive a Dying Hydrangea with Root Rot
The hydrangea has the best chance of recovery if you transfer it to a more advantageous area with improved drainage. However, growing hydrangeas in pots and containers is the best option if your garden soil is particularly soggy because they have better drainage and you can easily provide the best soil conditions (by using compost) rather than trying to modify your garden borders to suit the hydrangea, which can be challenging. Hydrangeas Dying Due to Small PotsWhen cultivating hydrangeas in containers, pick a container that is at least 16 inches wide (with good drainage). Drought is brought on by the tendency of hydrangeas growing in small pots to dry up far too rapidly. Small pots absorb heat from the sun more quickly and have less soil volume, which means they retain less moisture and cause drought. Large pots work nicely for hydrangea growth. In order for the root system to have adequate room in the soil to obtain all the nutrients and moisture it needs, the pots should be big enough to prevent pot-bound roots. Transplanting your hydrangea to a pot that is at least 16 inches across will help it recover if it was originally planted in a relatively small container. The best time to move hydrangea into new pots is in the spring or fall rather than in the summer because transplanting when it’s cooler helps to lessen transplant shock and lowers the risk of drought. To give the hydrangea time to establish without having to deal with the drying effects of the sun, which can cause drought, keep the soil moist after re-potting and shield the hydrangea from direct sunlight for a few weeks. Too Much Fertilizer or Manure can Burn Hydrangea RootsAs 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:
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 signs of stress as a result of being recently planted in soil that has been amended 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:
FAQWhy is my hydrangea turning brown and dying?Key Lessons: Drought, excessive wind, and too much sun all cause hydrangea blooms and foliage to turn brown. The best conditions for hydrangea growth are protection from wind, wet soil, and dappled sunlight. The hydrangea blooms and leaves wilt and become brown because there is insufficient moisture around the roots. Why has my hydrangea died?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. Can you bring a hydrangea back to life?Put the hydrangea(s) in the hot water-filled vase. Let sit for at least one hour, then presto! fresh hydrangeas. Why does my hydrangea look like it’s dying?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. Can you bring a hydrangea plant back to life?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. Via https://thegardenhows.com/how-to-revive-a-dying-hydrangea-plant/
