What Causes Brown Spots on Spider Plants?
When brown spots go forth on your houseplants , that ’s always a telltale sign that something is off with your spider plant .
They may uprise differently depend on the cause , severity , and period of time of browning . They may vary in size , grain , and even shade of brownness .
chocolate-brown speckle come along primarily on the pourboire of the industrial plant but can spread across the integral foliage . Some spots become progressively heavy , while others remain barely seeable . They commonly seem as blisters at first then turn into ironical lesion .
In either case , roll in the hay the precise drive of the brown blot on your spider industrial plant will help you combat the predicament more effectively .
You ’ll want to inspect your houseplant closely to nail the problem . It also pays to think about the conditions your houseplant has been subjected to of late .
I ’ll walk you through how to identify each of the rough-cut causes of brown spotting in spider plants . You ’ll also teach how to remedy each of these typical exit that cause your houseplant to turn brown .
Algal Leaf Spots
If you park your houseplant in a warm , humid area , sometimes it can be infected by epenthetic algae call algal leaf spot . It ’s usually spread from one plant life to the next by rain but can be be adrift indoors by the fart .
If your spider flora has an algal foliage spot disease , you ’ll determine rough , mesh - liked Robert Brown to greenish - brown blotches on the afflicted leaves .
The diameter of each splodge measures roughly half an inch . But several blotches can bleed into one another to create what appear like a bigger splotch .
I have find oneself that algal leafage pip appear primarily on lenient , younger foliation . you may also see a stunted appearance on tips , stems , and other percentage . They often begin as lowly , pale green round smear before blossom into large reddish - brown lesions .
Most cases of algal leafage spots barely become more than a cosmetic take , as they make your houseplant look unsightly .
However , they ’re rarely fatal unless the infestation is so severe it covers nearly the intact spider plant . You should be able to get free of the algal leaf post disease using non - chemical method , such as :
Fungal Diseases
If you keep yourspider plant life in overly humidand hot conditions , the cause of the brown spots is almost always a fungal disease .
They typically lead off out as faint green spot , especially on the foliage tips , and bit by bit turn chocolate-brown . In some character , the spots can turn to the full disgraceful .
Here are the most common fungal diseases that may do brown staining in spider plants :
This fungous disease is make by algal - like parasitical organism . It appears as a soft , fuzzy - looking brown growth . It ’s mostly perceptibly on the lowly foliation of a wanderer flora but may evidence other symptoms like foliage mottling , foliage drooping , or stunted development .
Most terrible in fond , humid shape , this fungal leaf blight pretend mostly ripe foliation . They usually commence as lilliputian brown spot with yellow halos then turn into irregular brown spots ( around ¾-inch ) . Each severely impacted leaf may wither , get ruckle , or even fall over .
Leaf spots because of Anthracnose often start as little chicken or brown spots that grow into dark brownish post .
These fungous leaf spots begin on the undersides of mature foliage as somewhat round spots with a gray midpoint and drear brown margin . If you do n’t treat it for a foresightful sentence , the leave of absence will turn yellow and shrivel up .
As an amateur ( that was a farseeing prison term ago ! ) , I used to mistake powdery mildew with downlike mildew . The latter thrives in cool , moist conditions .
Powdery mildew is characterize by stain that start as white patches that eventually turn into yellow - dark-brown pip , often seen on the upper sides of the folio .
you’re able to use numerous strategies to treat fungous diseases :
For the discourse of Fungal diseases . Here are the antifungal agent i recommend :
Bacterial Diseases
If you notice sunken , washy brown , or black lesions / spots on your spider works , you may be manage with a bacterial disease .
Your houseplant will likely develop bacterial leaf spot if you keep it in a poorly ventilated field . Overwatering and too much humidness can exacerbate the disease .
There ’s no cure for houseplants affect by bacterial foliage spots . you may spray with a broil soda solution and use S - based or pyrethrum - establish atomizer . They ’ll stop the spread , but not cure diseased part .
Bacterial folio spots can be fatal to your houseplant . If the bacterial disease is systemic , you should get disembarrass of diseased function before they propagate to healthy foliage .
park your houseplant in a brightly - lit and well - aerate spot can go a very long way . Avoid overhead irrigation , as well .
Nutrient Deficiency
If your spider plant has brown spots , the houseplant may be suffering from a lack of nutrient . This may be due toroot rot , wrong lighting , or poor ground nutrition .
Leaves of wanderer plants low in nitrogen often turn yellow before developing browned spots . If everything else looks good except for brown on the leaf tips , this could mean that your houseplant is smoothing iron deficient .
lack in zinc or magnesium is unremarkably manifested in the form of brown touch on foliage near the center .
Ideally , you should apply plant food to your spider works every month in summer and spring . A water - soluble fertilizer is highly recommend . Avoid over - fertilization as plant food tan will also have dark-brown spotting .
If the brown smirch are indicative of nitrogen inadequacy , taste placing your houseplant in a smart area to see if the spotlight will evaporate . For iron lack , just one dose of iron - take plant food should be enough .
Edema
More mutual than most gardeners are uncoerced to take on , dropsy is a term in which the houseplant takes up more water than it can habituate . This causes the leafage jail cell to glut and rupture .
The rupturing often ensue in watery blisters , bumps , or musca volitans , specially on the undersides of the leaves . They ’re often crusty , wart - like raised blister that may turn over necrotic . You may befuddle them with bacterial or fungal foliage daub .
There are various ways you’re able to handle wanderer industrial plant brown berth triggered by edema reckon on the genuine suit :
Excess Light/Scorching
Exposure to excessive light can bring temperature stress to your spider flora . Your houseplant should be exposed to part sun and park in a reasonably bright spot . Do n’t rush your flora from a poorly - lit area to a sunny post .
For optimum growth , your spider plant should be kept in temperatures between 70 ° F ( 21 ° C ) and 90 ° F ( 32 ° nose candy ) . Too much light will not only shock your houseplant may make tissue wrong , often presented as brown spots .
The answer is simple : relocate your houseplant away from the scorch conditions . Move yourspider plant life to a spot that experience bright , indirect light . Avoid direct sunlight at all cost because it can cause scorching .
Frost Damage
As with scorching or excess brightness , frigid draft copy can also damage your houseplant ’s tissue paper and get brown billet to break . This is usually watch during the start of wintertime .
If your houseplant is locate near the windowpane , see if there ’s a cold draft , peculiarly at night . This is also vulgar for spider flora in unheated indoor garden and sun porch .
Again , relocating your industrial plant to a warmer spot will do the trick . check that your spider works is adequately insulated or keep the room warm . Simply turn on the heating organization , but maintain the temp in the 70 ° F ( 21 ° cytosine ) and 90 ° F ( 32 ° C ) cooking stove .
Low Humidity
wanderer industrial plant do well in moderate humidity ( somewhere in the 30 % to 50 % range ) .
Too high and too low humidity can spell day of reckoning for your wanderer flora . On the one hand , excessive humidness , peculiarly when coupled with warm conditions , is a formula for bacterial , algal , or fungal disease .
On the other hand , abject humidness mean the leaves of yourspider works will wilt and turn brownness on the baksheesh .
Low humidity is a common trouble during the wintertime month . To refine the issue , place your houseplant in a medium - humidity way . you may fog around the plant life at times .
Insect Infestation
Even though wanderer plants are typically hassle - free , they ’re sometimes inconvenience by aphids , scales , spider pinch , mealybugs , whitefly , and other worm . They ordinarily drill holes in the leaves and nurse out juices , leaving brown spots .
First , you must inspect your spider plants for anysigns of insect plague . If any of the insects cite above invade your houseplant , wash the hemipteron off outside or in the cascade with a strong sprayer of water .
Watering Problems
chocolate-brown spots on spider plants are usually a sign that you ask to reconsider your tearing habits . If you overwater your houseplant , then get out it to completely dry out out before the next irrigation , that ’s a formula for brown staining .
Excessive lacrimation broadly speaking leaves the potting soil waterlogged . This makes it difficult for the houseplant to absorb nutrients and oxygen . or else of soak it in water , keep a uniform watering number .
A wanderer industrial plant expand when the potting mixture dries out more or less between irrigation . Check the dirt after every four to five days .
If the soil mix is a mo dry to the skin senses , water the houseplant properly . Make indisputable that the water system bleed out of the bottom of the pot .
If the territory is waterlogged , scrutinize the root system for root rot . Remove disease roots and apply some anti - fungous to the rest .
Transfer the houseplant to a bigger pot and leave the waterlogged mix until it dries out a act . Repot your plant and maintain a good watering drug abuse from then on .
Fertilizer Burn
Brown stain on the leaves of your wanderer flora are often a sign of over - fertilization . This indicates an accumulation of common salt from excessive coating of plant food . It can also be due to softened water .
Spider plants require a niggling fertilizer to boost development . But , as with the human body and vitamins , too much can do more harm than good .
How to Fix Brown This
Water your houseplant until it derive out of the holes in the bottom . This will help drain out salts that have roll up from spare fertiliser . If the fertilizer burn is too severe , you might want to repot with fresh soil .
From here , fertilise your houseplant meagerly , only once every month in summer and fountain . Water - soluble plant food are well suited for spider plants .

Because there ’s no known cure for systemic bacterial leaf spots , you must take away severely morbid plant materials immediately to prevent further spread . habituate any proficiency that decrease wetness on leaves , improves aura circulation , or get down humidity :
Studies have show that a pee - soluble fertiliser with an NPK ratio of 19 - 6 - 12 or 2 - 1 - 2 is ideal for the wanderer works ’s optimal growth .
Park your plant in a bright , indirect sunlight pick out to foreclose nitrogen insufficiency . A fertiliser rich in iron , zinc , and magnesium should be hold once .
On the same distinction , you should avoid over - fertilization . apply a pee - soluble fertilizer once every calendar month or so in summertime or spring should be OK . nullify fertilizers that hold B or fluoride .
Excess Light

Over - fertilization , overwatering , hydrops , and alimentary lack may also make for a role in the development of wanderer plant brown smear .
If everything seems OK but there are still browned spots , check for insect pest like whiteflies , mealybugs , wanderer mite , scales , and aphids .
process the chocolate-brown spots will depend in the first place on the cause . However , salutary breeze circulation , humidness control , adequate urine , and brilliant light should prevent them from contract a toehold on your precious houseplant .
