Earlier this year , my hydrangeas ’ sweet sprouts burst forth in a vibrant green chromaticity . I decide to sprinkle lime around the root geographical zone in the dirt – a move that usually result in pink hydrangea – and remove them to large stool .
However , after a while , the farewell shifted to a subtlety of red , and the hydrangea blooms seemed to fall back some of their color .
Let me portion out with you the challenging reasons behind these unexpected change and the steps you’re able to take to keep this from happening to your hydrangeas .
My Potted Hydrangea Leaves Started Turning Red
Why Did My Hydrangea Leaves flex Red ? Could the red foliage be due to an increase in anthocyanins ? And if that ’s the case , why did this go on ?

1- Insight from My Local Garden Center
The puzzle begin to untangle at the local garden shopping mall , where they pop the question that the filth ’s pH level could be the perpetrator . While most plants privilege acidulous soil , pink hydrangea prefer a slightly alkaline surroundings .
Adding an excessive amount of lime can make the soil overly alkaline , hindering the plant life ’s ontogenesis and lead to red folio .
Reverting the ground to its acidic state might help the industrial plant bounce back to its original condition . right use of calcium hydrate in hydrangea soil provision can be a challenge for novices .
A more reliable method acting is to plant in acid ground and gradually adapt the pH with an alkaline fertiliser ( if you ’re aiming for pinkish hydrangeas ) .
2- Guidance from a Plant Specialist
The flora specialist I confabulate contribute another stratum to the enigma : aside from the ground ’s pH level , the hydrangea might have suffered stress from disturbed roots , do them to break and the leaves to redden .
Activities as innocent as re - potting or weeding could inflict wrong on the solution , look on the time of year .
Once the leaves have reddened , they wo n’t regain their original color within the same twelvemonth . However , as the ascendent restore , the leafage should revert to their distinctive hue .
The specialist recommend regular lachrymation and apply the appropriate plant food three clip a calendar month to cause newfangled root growth .
call back , it ’s crucial to waitress until the flora has to the full recovered from transplantation shock before fertilizing . After all , healthy root development is substantive for your hydrangeas ’ thriving growth .
3- Could There be Other Reasons Why Your Hydrangea Leaves are Turning Red?
When a hydrangea falls ill , its full organisation can be impacted – from the leaves and flush to the root system .
If you remark that only the leaf edges are drying out , this might indicate overwatering or a potassium deficiency in the soil .
to boot , if the soil is n’t acidic enough , your hydrangea may fight to absorb the vital nutrients it needs to raise . In this case , organic acidifiers can come in ready to hand .
On the flip side , if your hydrangea is receiving too much or too little water or sunshine , you may set out to see leaves changing color to brown , disastrous , cerise , or yellow .
Therefore , when selecting a permanent spot for your hydrangea , consider its specific motive – sufficient but not excessive wet . Seeing a rust fungus - like stain ? That could be from coarse sun vulnerability . Finding a semi - shaded berth under other trees and bush can often be the best solution .
If theleaves begin to yellow and fall off , this might be a sign of overwatering , while wilted - looking leaves could indicate unequal visible radiation .
dry leaves with a rusty hue could suggest a high nitrogen degree in the soil . Excessive nitrogen can harm your hydrangea , stimulating succulent - type leafage and new growth , which may pull in sap - sucking dirt ball .
This excess nitrogen can also prompt more foliation production than salad days growth , cauterize frail young etymon , and leave your hydrangea susceptible to root rot and nematode attacks .
Luckily , the resolution is unproblematic : add some raw constitutive affair into the soil to poise the nitrogen levels .
Wilting leaves might be due to drafts . In this case , weigh moving the plant life and forfend sudden temperature changes .
Yellowing and redden leaf can also result from insufficient nutritive uptake and low acidity levels . To call this , start fertilizing three time a month from March until mid - July .
Red Leaves and Fungal Infections Spots and a whitish coating on your hydrangea could be a sign of a fungal disease .
While hydrangea generally have good exemption against fungous diseases , they can still occur , lead to brownish - violent or dark leaf discoloration .
If the leaves first turn inglorious and then recrudesce a white finish , it might be a symptom of root rot , which get in the origin system and can touch the overall appearance of the works . Using antimycotic can aid mitigate this result .
Leaf drying might be due to other factors as well . browned and crimson spot could be a sign of Septoria leaf spot , characterise by circular spots with darker edges than the center .
These pip can seem on leaf , halt , and cuttings alike . Without timely interference , the foliage will start to dry and break , imperil the plant ’s survival of the fittest . This disease often shows up in the fall , and give copper - based solutions can ameliorate the situation .
For the treatment of fungal disease . Here are the fungicide I recommend :
4- Viral Diseases and Their Effects
Have you spotted brown spots tinged with red on your hydrangea ? This could signify a viral disease . The essence of such a disease often manifest as curl hydrangea leaves .
Sometimes , the disease can even diffuse to the flower bunch , a assure sign of the disease ’s severity . The bloom might start to ebb , producing minor flowers , or give way to form buds at all .
If these symptoms seem , do n’t waver until your plant droop whole or infects nearby plants .
unluckily , there ’s no therapeutic for foliage spot due to viral contagion . Your best trend of action is to protect your other plants from becoming infected .
Preventing Red Leaves on Hydrangeas
I ’ve covered the possible reasons why hydrangea foliage might dry out or sprain red . Yet , the most worthful assist you could provide your industrial plant is preventative caution .
Diseases typically affect weak plant , so ensuring proper fear is vital to safeguard your hydrangea . Direct sun and teetotal soil can inflict significant damage on your flora .
During hot weather condition , make certain to water your hydrangea every other 24-hour interval . Furthermore , the soil you choose can contribute to folio stain .
Therefore , it ’s important to know what type of soil your hydrangea will boom in . To protect your hydrangea from various disease , maintain moist soil and avoid waterlogging .
Many veteran gardeners consider that hydrangeas with racy flowers are the strong and least likely to wilt . However , this does n’t mean that other types of hydrangeas are inherently weakly .
All plants need time and meticulous attention to receive their needs . With the correct care , your hydrangea will blossom abundantly and for an extended period , providing a delightful sight for all to bask .
