The elephant auricle flora is quite a looker , but it takes some hard work and time togrow its large , ornamental leaf .
That take in it more sore to see otherwise beautiful glossy leaves turn John Brown . Wondering what could be incorrect ?
Leaf burn is the most likely cause for elephant ear leaves turning brown . It occurs if exposed to direct sun , too much warmth , fertilizer burn , or too little humidity . dark-brown leaves could also be a sign of insect plague , disease , or piddle supply progeny .
Fortunately , most of these issues can be avoided or corrected if detected early . In this billet , I ’ll excuse how to diagnose , delicacy , and prevent brown leave on elephant ear .

Causes of Elephant Ear Leaves Turning Brown
[1] Leaf Burn and Drying Out
foliage burn is the most common cause of brown elephant capitulum . It ’s commonly due to too much direct sunlight or heat . In the summertime or when you take your works out of doors , you ’ll notice this .
The sear heat of the Lord’s Day will singe the leaf . As a result , the foliage tips and edges turn an unappealing brown coloring material , dry out out , and wither . The entire leaf may become burnt and dry as the leaves apace lose moisture .
Do n’t care ; leaf tan is improbable to stamp out your elephant ear . The problem is that it ruin the appearance of your flora ’s leaf , make them unattractive . After all , it ’s the elephant ear ’s foliage that make it so appealing .
The foliage will become droopy , curled , and extremely dry if the folio suntan is due to too much warmth . And if nothing is done , the leaves will finally strike off .
Other factors can make or exasperate foliage suntan and dry . The most obvious one are too little humidity , underwatering , too much fertiliser in the grease , and cold / hot drafts . Overwatering is most potential to blame if the soil is muddy or wet .
For the elephant ear to expect its best , it must be peril to natural light . It , on the other paw , disdain direct sunshine . lay it in an sphere that receives plenty of brilliant diffused or indirect light .
If you desire to protect your flora from the hot good afternoon sun , apply a absolute drape or unsighted .
I place my elephant ear plant in front of an due east - face windowpane so that they are easy to care for . They will apprise the easy but nourishing light of the early morning . If you’re able to see a slight shadow or dapple in the afternoon when the sun is scorching , take advantage of it .
Watering , befog , and increase the amount of ventilation available to your works are all beneficial . They will not only protect your flora from leafage burn , but they will also assist in its recovery by allowing it to recover more rapidly .
[2] Too Little Water
The elephant ear is a H2O - love tropical works . Just by wait at its broad , plush - looking foliation , it ’s obvious the plant prosper with consistent moisture .
That ’s why it comes as no electric shock that underwatering causes its leave to crisp and turn brown .
If you let it get too athirst , your elephant ear will respond by wilting and curling . After that , the leaf wind and edges will turn ugly browned , crisp up , and appear burnt . Leaf browning will then progress from the margin and eventually treat the whole foliage .
If your plant is shaggy-coated , you ’ll first notice browning on the outer leaf . The Robert Browning commonly begins with scummy and older leaves . In extreme case of dehydration , the brown leaves will dry out almost wholly , shrivel , and droop .
gravid white-livered spots or patch at the tip or edges of the foliage are another plebeian sign of an underwatered elephant auricle .
[3] Too Much Water
If you irrigate your elephant too frequently , surplus water system will collect on the edges of the leaves , cause them to wrench brown . As a result , the leaves will get down to waste and turn chocolate-brown around the edges and tips . As you might expect , the browning will progress and eventually get across the entire leaf control surface .
In most cases , damp conditions advance the paste of fungous and bacterial disease as well as pestis . They may also conduce to or accelerate the browning of leaves .
[4] Fungal Leaf Blight
Fungal leaf blight is the most common disease that blemishes the elephant ear leaves . It ’s caused byPhytophthora colocasiae , which thrive in damp conditions . The fungus spreads through water .
The fungous leafage blight cause by Phytophthora come along as small dark brown , tan , or royal round spots on the foliation at the beginning of the disease . From the center of attention of the wound , a decipherable guck is exude . When disclose to air , the muck transforms from a reeking clean colouring to a purple or yellow hue .
In muggy conditions , the small brown lesion expand chop-chop and coalesce into big brown patches . Other symptoms of the fungal blight include :
Good sanitation practices are your proficient stake at pull off fungal leaf blight :
snip away severely diseased or dead leaves . Dip in or pass over the trim down tool using rubbing intoxicant to sterilize it after every snipping .
I unremarkably use copper - base fungicides to keep Phytophthora fungous foliage blight at true laurel . Spray it on the foliage of your elephant ear soundly . utilize every seven days when it ’s sloshed ( or every 14 day when it ’s dry ) until you curb the infection .
[5] Pythium Rot
A disease of the elephant ear that is even more austere than Phytophthora leaf blight is Pythium guff . Pythium pathogens , which are found in soil , are creditworthy for the outbreak . This mintage propagate primarily through irrigation piss , and it thrive in to a fault wet soil and humid shape .
The comportment of rooting theme below the soil line point that pythium rot has infected your elephant capitulum . They smell bad , are soggy to the touch , and are colour , mordant , or rusty brown in appearance .
Above the soil , the most common signs and symptom include :
You must use a multi - prong scheme to curb and manage pythium rot . The most significant tip is to keep good healthful practices .
[6] Phyllosticta Leaf Spot
The fungusPhyllosticta sppcauses this fungal folio spot disease . Unlike Phytophthora leafage blight or pythium rot , it is rarely fatal to your elephant ear . However , it can wrack your plant life ’s coming into court with unsightly chocolate-brown spots .
Early signs of the disease let in a spray of small H2O - soak oval or round lesions . These wound may appear black , chocolate-brown , hoary , or beige . They will grow big and flux to make large blotch or patches that can blanket the whole leaf .
These foliage spots will dry and drop out in some cases , leaving scruffy holes in the foliage . For this reason , your elephant auricle will look as if it has been sprayed with bullets .
If Phyllosticta leaf spot disease is creditworthy for leaf browning , look out for foliage orstem dieback on your elephant capitulum . Heavily infected leafage may also turn yellow and fall off .
Most contagion happen through polluted water . So , it ’s essential to practice thoroughgoing irrigation body of water . And be careful not to splosh the leaves when watering .
Sanitary practices can also go a very long way . Use sterilized gloves and other upkeep particular when care for your plant life . Be indisputable to remove & dispose any dead leaves or plant materials that settle around your elephant pinna .
Prune and space out your plant life to encourage ample aviation circulation . I highly discourage overhead lacrimation , as well .
murder and underprice stirred leaves or even the whole plant in a covered trash bin .
Cultural controls are normally enough to curb Phyllosticta leaf spot disease . Most Cu - based fungicides hold promise against Phyllosticta leaf place . However , you may habituate chemical controls such as propiconazole , mancozeb , and copper hydroxide .

[7] Pest Infestation
The visual aspect of browning on the elephant ear plant ’s leaf could signal the start of a pest infestation .
scrutinize the underside and top of the leave exhaustively for louse pest sucking sap from the leaf . Some of them also chew on the edges of the leaves , leaving brown German mark .
Symptoms : Look for spider mites on the backs of the leaves , especially in raging & ironic conditions . These grovel bugs spin fine webbing to protect their colonies . They also leave grey streaks on the leaf .
symptom : If you see an United States Army of tiny unripened bugs that congregate on the leave and stems , you ’ve acquire an aphid encroachment .
symptom : If you see oval - shape insects hide by white cottony or waxy filaments , then mealy bug are the primary causa of leaf browning . You ’ll distinguish them on the stalk nodes and along the leaf vena on the undersides of folio .
Mealybugs also sop up sap and secrete honeydew . As such , you ’ll most likely notice some pitch-black sooty clay sculpture . ant may also farm the syrupy substance .
If their numbers are significant , there will be cosmopolitan growth stunting and yellowing of leaves . The leaves may also be covered with black spots .
[8] Extremely Low Humidity
Elephant ear prefers ardent humid condition . Some metal money are produce in smashed areas in Hawaii . If the gentle wind surrounding your elephant ear is dry , the leaves will sour brown .
If low humidness is the perpetrator , the stick with primary polarity will show :
[9] Fertilizer Burn
The elephant ear is a dense feeder . You ’ll have to fertilise it regularly with plant food to reinforce the nutrients in the potting premix . Once a month , apply a water - soluble 20 - 20 - 20 plant food .
However , if you give too much fertiliser , the salts will build up in the soil and sunburn the stem , leading to riff browning .
Is It Normal for Elephant Ear Leaves to Turn Brown?
In some cases , the honest-to-god leaves on your elephant ear will by nature dry out , wilt , and turn brownish as they age . Of naturally , they will come get onto down . It ’s a natural direction of getting disembarrass of honest-to-goodness leaf in purchase order to make room for new growth and direct resource toward it .
