Hydrangeas love to soak up the morning sun . But if the shrub are sit down in the Dominicus during the hottest part of the sidereal day , they ’re in all probability getting way too much light . Hydrangeas take 4 to 6 hours of sunlight per daylight . If you hold up in a ice chest climate , then your hydrangea will likely be able to endure more sunlight . But if your growing zona is on the warmer side , they may demand full shade in the afternoon to help oneself them cool off .
If your hydrangeas are getting full sunlight in the good afternoon , they ’re believably struggling . You ’ll notice yellow foliage and poor bloom yield . When temperature are in the upper eighty or higher , the hydrangea ’s leaves will start to burn and turn brown and flowerheads will misplace their color and wilt .
If your hydrangeas are break down because they ’re acquire too much sunlight , you may notice that the surrounding dirt dries out apace . Your plants will also likely persist wilted , no matter of how much you irrigate them . When hydrangeas broil in the sun , no amount of water will serve them recover .
Too much sunlight causes yellowing foliage and wilting flowerheads.
The solution: move the plant to a shadier location
If your hydrangeas are have too much sun , the best thing to do is move them to a shady location . Transplantlarge hydrangeas that are growing in the ground to a place where they ’ll get morning Sunday , but spend the rest of the day in the shade . deliberate moving smaller hydrangea to pots , so you may easy move them around to catch the sparkle as demand .
Whether you decide to imbed your hydrangeas in the footing or in stool , try maintain them on the east side of a edifice or a tree . This way , they ’ll get the morning sunshine they thirst , and be well - protected from the heat of the afternoon .

Hydrangeas are perennial and , look on their variety , they ’re hardy from zona 3 through 9 . These shrubs originate well in mild mood where temperatures stick around between 50 and 70 degrees Fahrenheit .
If you hold out in a hotter part , it may make sense to grow your hydrangeas in full ghost . But this can have a prejudicious essence on the flora ’s wellness . If your hydrangeas reckon sickly , observe them during the day to see how much sun they receive . If it ’s less than 4 hours , then the plant are n’t get enough lighting .
Ensuring hydrangeas get enough shade will help keep their foliage nice and green.
The solution: transplant the hydrangeas to a sunnier spot
Hydrangeas need light to photosynthesize . Without sunlight , they basically starve , because they ’re unable to convert the nutrient , carbon copy dioxide , and water supply they ingest into vigor . Transplant your hydrangea to a sunnier location so they can get the light they require . Four to 6 hour of morning sun is idealistic . In blistering growing zones , you may find that filtered morning sun is sufficient to keep the plants unripened and blooming consistently .
The problem: underwatering
Another understanding why many hydrangeas pass is that they go unwatered for tenacious periods . It ’s true that hydrangeas do n’t like to seat in boggy soil . But if you go too long in between waterings , or ifyour ecoregionis experiencing a drouth , your hydrangea are probably not arrive enough moisture .
symptom of underwatering can mime those of excessive sun . If you ’re sure your hydrangea is getting just the right-hand amount of sun , but its leafage are still turn dark-brown and dry up , then you should suspect desiccation next . cling your finger an column inch or two into the soil . Does it palpate dry and powdery ? That ’s a full sign that your hydrangea is hungry and could use a drunkenness .
The solution: water the plants
If your hydrangeas are athirst , give them a boozing ! hydrangea love moist territory , sowater them thoroughly with a garden hose1 to 3 time a calendar week . Watering the plants profoundly encourages the roots to grow farther into the soil .
How much water your hydrangea plants need can change depending on where you live and how much rainfall your arena receives . During drouth , your hydrangeas will need to be watered more often . You ’ll also need to water your hydrangeas more often if you subsist in a warmer climate . In moderate regions that incur regular rainfall , you may only require to water your hydrangea once a hebdomad .
Young hydrangea plant life require more piddle than previous plants . even waterings help the flora become established . matured bush that have understand a few farm seasons are somewhat drought - patient of , so they can recover if you incidentally block to irrigate them once in a while .
Too much sunlight gives hydrangeas a washed out appearance.
Always examine the soil before watering your hydrangea to keep off overwatering them , and moot spreading a layer of woodwind micro chip mulch around them . This will help oneself the soil keep back a healthy amount of moisture and also prevent speedy dehydration .
The problem: overwatering
Underwatering wo n’t do your hydrangeas any good , but neither will overwatering . Hydrangeas opt to originate in moist grunge . That little touch of dampness preserve their roots cool and allows them to absorb nutrients the right way . But too much water prevent air from reaching the roots , and the plants suffocate .
The first sign that your hydrangeas are overwatered is yellowing foliage . After that , the leaves will wilt and work brown . This can throw gardener into believe that the plants are in reality underwatered , stimulate them to give the plants a salutary soak , thus perpetuating the criminal cycle .
Again , finger the grease around your hydrangea .

If your hydrangeas have been overwatered, give them a chance to dry out.
The solution: stop feeding the plant
First thing first : stop feeding your hydrangea . If they ’ve been overfertilized , more fertiliser certainly wo n’t help them . water system the works thoroughly to help even out out the redundant nutrient .

It ’s also worth remark that your hydrangea ’s variety can determine how it will react to dirt pH. For exemplar , if you ’re growing a blue hydrangea cultivar , like ‘ Nikko Blue ’ , it may show sign of poor health if it ’s kept in alkaline stain . The opposite may be straight for pinkish cultivars , like ‘ Red Sensation ’ .
The solution: balance the soil pH

If you moved your hydrangea to a new location lately and now it looks like they ’re dying , then they ’re probably suffering from organ transplant shock absorber . hydrangea can get stressed out easily . They do n’t like it when their roots are raise up . So affect them from one blank space to another can take a toll on their health .

If the plant life moves , soil and all , as one mass and can easily be branch from the edges of the pot , then it has outgrow its container . potbound hydrangeas will drop dead if they go untreated .
Nutrient-deficient soils can kill hydrangeas.
The solution: repot the hydrangea
There are two way of life to fix a rootbound plant . The first is to rationalise the roots and return the industrial plant to its original raft . This method acting ferment pretty well forrosemaryandFrench lavender . But because hydrangea are highly tender about their roots , this scheme may result in the hydrangeas die .
The second fashion to fix a rootbound plant is to move it to a new kitty or stick it in the land . Rootbound plant want more room , that ’s all there is to it . So whether you resolve to transplant your hydrangeas to a new container or out to your garden , it does n’t really weigh . What weigh is that you play fast .
Rootbound plants live on borrowed time . The rather you give them more quad , the greater their luck of recovery . When transplanting rootbound hydrangeas , obviate disturbing the root . adverse to popular belief , there’sno need to break up the rootsof a rootbound flora . Simply pay them more space is enough to help these plant recover .
Hydrangeas need plenty of nutrients to produce vibrant blooms.

Both of these experimental condition can make hydrangeas appear sickly .
Rust is a fungal transmission that induce rust - colored splotch to develop on the hydrangea ’s leaves . Over sentence , plants may fall behind their leafage .
