Alocasia , usually known as the elephant ear is a tropical industrial plant with beautiful large leaves and zebra - like stems . Since it is a tropical plant life , Alocasia fly high in a humid environment .
So , have you realized that leaves in your Alocasia plant have brown fleck and wondering what caused it and what to do to eliminate them ? If yes , numerate yourself prosperous because you have landed in the right seat .
The most commoncause of brown musca volitans on alocasialeaves is fungous disease and pest plague . Overwatering , low humidness , temperature tenseness make the plant vulnerable to disease and pestilence . Besides exposure to superfluous light and fertilizer can also have the elephant’s ear leaves to develop dark-brown spots .
Brown billet in Alocasia is triggered by many reasons , most of which are preventable and even correctable .
In this station , I will discuss the most vulgar reason why Alocasia go away get brown spot and how to treat them .
In this article I will discuss each possible grounds and how to handle them effectively .

Causes Of Brown Spots On Alocasia Leaves
browned spots in Alocasia may be cause by many ingredient . In this section , I am going to discuss the possible reasons why your Alocasia leafage have brown spot and how to treat each trouble .
1. Low humidity
Alocasia plantis a tropic plant , meaning that it prosper in a humid environment . If it engender too dry , then it is more probable to acquire brown point .
So , if you notice chocolate-brown spots on your Alocasia industrial plant , particularly during the winter season , the most likely campaign is low humidness .
During the winter season , humidity level usually drop because nerveless air hold few moisture than warm line .
If your household apply a forced heating organisation , the problem will even be risky because furnaces use combustion to create spicy aura , which burns out most of the piddle vapour present in the family .
As a resultant role , your Alocasia plant is more likely to make grow brownish spots during the wintertime months .
The good news that is the job can be posit by increase humidity around the plant .
There are many ways to raise the humidness around the Alocasia plant as discussed below .
One of the most in force ways of raising humidness around the plant life is by mist the works as often as you may .
mist over the plant life will expose the dirt and leaves to water particles that will evaporate , thus raising humidity around the flora .
Another great mode to arouse the humidness around the Alocasia plant is by commit cups , bowls , or any other container around the works .
The goal here is to expose air to body of water . piss will evaporate thus levy humidity tier around the plant .
Another quick but good method acting of raising humidness around the works is by using a humidifier .
Besides keep your house to a certain humidness grade during the winter season , the humidifier can also produce a humid environment for your Alocasia plant .
you may also use a pebble tray to increase humidity , add enough body of water to cover the pebble , then localize your Alocasia plant on the tray .
The pebble will keep the plant life above the urine , thus preventing the root from getting wet . Moisture around the plant will increase as water in the tray disappear .
2. Rust
This is a fungal disease that bear upon all type of industrial plant , include Alocasias . Rust is get by a want of sunlight , high humidity , and warmth .
Once the disease has adjust in , a sudden increase in warmth can make it move on further , leading to more brownish spots on the Alocasia leaves . If the trouble is not treated on time it will kill off the foliage .
The first sign of the zodiac of rust fungus on Alocasia leaves are tiny spots on the Alocasia that array in coloring material , from rusty brown and scarlet to orange . If left untreated , the spots will get bigger and turn into bumpy looking pustules .
The rust on your Alocasia folio is normally not fatal but it can compromise the works ’s wellness . Additionally , it usually set out bad with time , meaning that if you do n’t cover it on time , then it will spread to other section of the industrial plant , leading to scrubby development .
rusting in Alocasia in the main thrives in damp condition . Therefore , it is recommended that you obviate overwatering your Alocasia works . alternatively , practice drip irrigation or a souse hose to keep piss off the foliage .
Proper spacing of pallets can also help to prevent rust . Therefore , when implant the Alocasia , ensure they are well spaced to advance well air circulation .
It usually spread fast . So , when you acknowledge that some leaves on the plant have been pretend , prune or pick them immediately to prevent the disease from spreading .
However , this trick only works if only a small number of leaves are affected .
If there is too much moisture around the plant , modulate it using a dehumidifier . Lowering humidness around the plant to recommended levels will serve to prevent the disease from spread . Always pee in the morning to allow the industrial plant to dry out before the sunsets .
3. Excess Light
Alocasia is tropical , meaning that it does not perform well when expose to sun for an extended period .
Inner Light is one of the most crucial factors needed for the growth and eudaimonia of your Alocasia plant . This essential energy is needed by the industrial plant to grow , bloom , and produce healthy seeds .
However , too much sunlight is harmful for alocasia because it creates potentially damaging free radicals that may absorb too much vigor than what the plant life can plow , thus bring forth reactive species of atomic number 8 that could destroy the plant .
If your Alocasia plant is exposed to too much sunshine , it may become beach , scorched , and limb , leading to the coming into court of brownish spots .
sign that your Alocasia industrial plant is exposed to too much light admit the presence of yellow leaves , even wan foliage , and brown spots on the peak of the leaves .
The solution to this problem is lower plant photo of visible light to the recommended floor . For instance , if the plant normally sits next to the window where there is too much light , then it is advised that you move it off to a spot where there is less photo to sunlight .
you may also take the plant forth from direct sun so that it only gets indirect lighting that is not damaging .
Besides light exposure , clean intensity also matters a fortune . For example , if your Alocasia flora was okay facing the west side windowpane during the winter time of year , the same will not utilise during the summertime season .
brightness volume varies grant to seasons . This means that light intensity in the west - facing windowpane during winter calendar month is different from sun intensity during the summer calendar month .
It is urge that you move your Alocasia plant to different role of the house , depend on light chroma to keep scotching .
Remember that promiscuous harm can not be undone . So , check that you take quick action as soon as you mark the presence of scotch equipment casualty on the leaves .
4. Mildew
Like mildew that attacks habitation , mildew on your Alocasia is a fungous disease , induce by gamey humidness levels .
Mildew can slow down down the increase of your Alocasia plant life and if the infection is severe enough , the works may die .
There are two type of mildew , including powdery mildew and downy mold . Downy mold occurs in cold and humid condition while powdery mildew happens when the plant ’s soil is too ironical .
Powdery mold is the most common type of mold that attacks the Alocasia plant . It commonly start as awhite dapple on the leaves , but finally , turns to brown spots if the plant life is not treat on time .
Powdery mildew can percolate important nutrients from the plant , causing the leaves to yellow and wither .
to boot , if most part of the folio become handle with the mold , it will pretend the appendage of photosynthesis and with time , the bear on farewell will come off from the plant prematurely .
The best way to foreclose powdery mildew from assault your Alocasia plant is by keeping the soil in optimum term . This means control that the soil is not too ironical or too wet .
During the wintertime season , urine the flora early in the morning , to give it enough time to dry out before the mean solar day ends . Likewise , during the summer season , irrigate the plant to prevent the soil from drying .
5. Pest attack
pest also cause brown spots on Alocasia . Pests such as mealybug can do monolithic damage to the leaves , leaving brown spots throughout the leafage . This type of pest is common in houseplants and usually ruin everything , from leave and stems to roots .
Other insects such as scales , leafhoppers , aphid , and true bugs normally snipe the leave of Alocasia causing adolescent or spot of foliage and foliage curling .
It is advised that you contain your Alocasia flora ( peculiarly if you notice sensationalistic spots ) to see if there is a mien of the pests .
If you find their front , go a footmark further to identify the type of pest that has attacked the plant life . identify the blighter that has set on the flora will aid you use the ripe elimination technique .
For example , if your dapple mealy bug on the Alocasia industrial plant , care for by removing the pest with an alcoholic beverage - soaked cotton bud .
Most pests like spider mites fly high in damp conditions . Therefore , secure that you keep wet level around the plant low to discourage pests such as spider pinch from attacking the plant .
you may also get disembarrass of pestis by spreading the correct insecticide . Please do n’t spread any insecticide that you come across .
alternatively , research to see if the insect powder is effective in killing the pest without harming the plant .
6. Root rot
ascendent rotting is a character of fungal infection that affects the root of the Alocasia plant . Of naturally , you may wonder how rot is associated with brown billet on the leaves .
The ecumenical wellness of the ascendent affects all other parts of the plant , including the leaves . If the root is not in estimable shape , a brown spot will bug out forming on the leaf .
Therefore , if you notice yellowing or wilting of the works , then that is a clear sign that your elephant ear has root word putrefaction . This fungous disease can circularise very tight if bequeath untreated for long .
audit all Alocasia plant source in your garden and discard any plant that is affect by rootage rot . This is the first action mechanism to take to prevent the disease from spreading to other plants .
Another elbow room of treating this disease is by maintain the PH of the soil below 5.5 . Acidic soil is more resistant tothielaviopsis basicola , the fungus that stimulate radical rot .
Also , make certain that the potbelly has good drain to prevent creating staring condition for fungi that cause root decompose to thrive .
7. Fertilizer issues
Brown spots on the Alocasia are also triggered by implement too much fertiliser or using the wrong fertiliser .
For instance , if you practice too much fertilizer or implement it at the haywire meter , there is a chance that your Alocasia plant may suffer from fertilizer burn ( scorching of leaf as a result of excess plant food ) .
Too much fertilizer may also sunburn the plant ’s roots , create it vulnerable to disease and insects .
Therefore , if you fleck chocolate-brown foliage on your Alocasia plant , then it could be as a result of too much fertilizer or using the wrong plant food .
The first solution to this problem is ensure that you apply the right amount of plant food . Using the wrong fertilizer will attract pests that will cause more damage to the plant .
If the brownish maculation is a result of applying too much fertilizer , level the soil to flush out excess fertilizer salt .
If this proficiency go wrong to process , then you will have no choice but to transfer your Alocasia plant to wise soil that is free of fertilizer .
8. Watering Problem
If you notice brown post of drying leave , then that is a augury that your Alocasia flora does not receive enough water .
Like other tropical flora , the Alocasia works needs frequent lacrimation to hold out and thrive .
If you do n’t give it fair to middling water , brownish spots will appear , and with sentence the entire folio will wither and die .
The best way to know if your Alocasia plant does not receive enough water is by checking the condition of the soil . If the soil is too dry , then it means that the soil does not welcome enough water .
The result to under watering is providing enough water to your Alocasia plant . Ensure that you irrigate the plant at least once every mean solar day ( in the morning ) .
Please do n’t allow more water than what the works requires . Overwatering is as bad as under - watering .
Also , research to understand the plant water require and be consistent in providing passable water .
9. Temperature Stress
Temperature stress in plants is divide into three categories depend on the stressor . They admit gamey , chilling , or freeze .
Temperature stress has many negative effects on Alocasia , including reduced photosynthesis , low-spirited sprouting rates , brown spots , growth lag , and death of the plant .
One of the ways to curve temperature stress in your Alocasia plant during the summertime season is by render undecomposed souse piddle to the plant at least once per week .
Also , ensure that the filth has the right wet . During the winter season when the temperature is cool , protect the flora from uttermost temperature by keep it in a dependable location where the temperature is friendly to the plant .
FAQ
