One of the most harrowing experiences is discovering brown spots on the glossy leaves of your genus Schefflera .
They not only regard the industrial plant ’s aesthetic , but they can also put its wellness in jeopardy . So what could be the cause of your umbrella plant ’s distress ?
Fungal leaf spots and ancestor rot are the most common causes of browned spots on Schefflera leaves . Remove to a fault spot leaves and use an appropriate antifungal agent . Increase air circulation , deflect overwatering and annul splashing leafage as preventative measure . Overexposure to direct sunlight , pest plague , and physiological disorders are all possible causes .
Now I ’ll go over how to identify and treat each of the causal agency .

What Causes Brown Spots on Schefflera?
[1] Fungal Leaf Spots
If your Schefflera has relatively large dark brownish smear , they ’re most likely fungal folio spots . Commonly induce by the fungusAlternaria Panax , these spots make on top of leaves and may have a jaundiced halo .
Alternaria leaf spot disease commonly affects matured leaves closer to the ground or near the crown of the Schefflera . The fungus flourish in quick , humid environments , so it ’s likely to strike in other spring .
It often manifests first as little dark-brown spots frequently edged in yellow . They will then expand and bleed into one another to organise large , unpredictable dour brownish blot . In some instance , these pip may shorten out a target - like doughnut pattern .
Overcrowding your houseplant may further the entering of Alternaria leaf spots , as the fungus spores pass around via poor handling of plants , garden tools , splashing H2O , and irrigation .
In addition , the fungus that causes the disease may re - taint your plants yearly because the spore are preserve in plant debris .
Poor breeze circulation and overwatering may also act as a role in the emersion or diffuse of fungous foliage spots . That ’s because the fungi fly high in environment that experience protract bouts of damp .
As the fungal disease advances , the stain may coalesce , and the whole leaves may turn brown or sensationalistic and blacken .
The center of areas may also fail off and overlook , leaving shot - hole behind . In dangerous cases , the Alternaria spot disease may spread to the radical and other persona of Schefflera .
In the last , the heavily - affected leave will start curling up , then wither and fall off .
Remove and destroy infected leaves and plant materials forthwith .
Early in the saltation , use a commercial-grade copper color - containing fungicide to help moderate , stop , or prevent Alternaria leafage spots from developing . ( Check the late toll on Amazonhere )
in effect sanitation and preventive measurement can also help , which include the following :
[2] Bacterial Leaf Spots
Suppose your Schefflera has atypical brown spots on the seat of the leaves . In that slip , bacterial leaf dapple disease is most likely to blame .
This bacterial disease is because of the bacteriumXanthomonas campestris pv . hederae . Pathogens are typically spread out via transplants and poor irrigation practices .
The first sign of Xanthomonas leaf spot are dull grey water - soaked lesions on older and small foliation .
small-scale , corked , maverick spotlight on the downside of the leaf may also seem . However , they may formulate across the vegetation .
As the bacterial disease get on , these lesions will turn into brown smirch . The toasting of these spots is accelerated by high humidness and temperatures . They can also arise to a diameter of one - fourth of an in .
The mature Xanthomanas foliage spots are typically tan or short brown in the center , with a yellowish halo .
If the humidity grade is too low-down , the spot will die and settle in , leaving shot holes on the leaves . In addition , the bacterial leaf trouble may do the leave to reverse yellow or completely brownish before falling off the Schefflera .
Your Schefflera may succumb to bacterial disease if not treated readily .
Xanthomonas leaf spot disease is almost unimaginable to moderate when it has become a full - blow contagion . What ’s bad , there is no known cure for the disease .
Early controller , combined with preventive measures and good sanitisation , are your serious bet :
[3] Root Rot of Schefflera Due to Overly Damp Conditions
Yes , Schefflera is a moist - loving tropic beauty . Too much water , however , will have the soil to become muddy and eventually kill the roots .
Also , root putrefaction will appearbecause of the minify ability to imbibe food , induce your works to become malnourished .
ascendant rotting is the most probable movement of brown spot on Schefflera leaves trimmed icteric . Even if the soil ’s open appears ironical , the source ball may be surrounded by a soggy or waterlogged medium .
If this is the case , the brown spots will continue to appear even if you line up the temperature , humidity , twinkle , and other lucky growth conditions .
appear for signs of pitiable drainage in your Schefflera :
Any of these trouble must be address right away .
The next measure is to repot your Schefflera . Here ’s how it works :
[4] Overexposure to Direct Sunlight is scalding the Schefflera Foliage
If the top leaves have ivory lily-white or browned smear , sunscald or burn is the most probable cause .
Your umbrella plant has probably been exposed to too much direct sunlight . I marvel if it ’s on the sill of a window with southern pic .
These brown spots will most probably come along during the most humid and hot summertime or other spring .
This is especially true if you move it apace outdoors without making a slow modulation .
Overheating leaves can cause them to scald or burn down . Dark brown spot will appear as a result of the price . In increase , the leaves may turn dark-brown at the edges or dry out and become crunchy .
other detection and discourse of sun scalding are critical . It ’s respectable to slay any scorched or brownish - spotted leaves , as they ’re unlikely to return to park .
come out your Schefflera in a shady maculation away from the sunshine . When it ’s red-hot outdoors , you should move it aside from your windows that face south and west .
Protect your Schefflera works from sunburn by covering it with a tad material .
[5] Frost Damage
Because Schefflera is a tropical plant life , it can not hold out rime , nose candy , or temperature below 60 ° F ( 15 ° C ) .
When your works has hoar harm combined with underwatering , you ’ll notice far-flung browned catching , and the leave-taking will fall off quickly .
Aside from defoliation , other sign of frost hurt include :
If your genus Schefflera drops too many leaves , try move it outdoors in the saltation . soundly water it .
[6] Brown Spots are Caused by Pest Damage
Pests seldom bother Schefflera , but aphid , scale , and spider mites can be specially troublesome for indoor works .
They enjoy sucking out the sap and leaving damaged holes and brown office on the foliage .
You most likely have an aphid infestation if you see honeydew voiding that ensue in black sooty mold .
Due to malnutrition , affected foliage may turn sensationalistic and even drop off . Another common symptom of an aphid infestation is the distortion of raw growth .
If your Schefflera is planted outdoors , it may be vulnerable to other pests such as spider tinge , mealybugs , fungus gnats , and scale insects .
In increase , browned spot and sooty cast will seem due to their plague .
You ’ll require to practice a q - tip soaked in alcohol to take out each one . Reduce the universe as much as potential by remove as many as possible .
Pruning infest areas or using the q - tip method acting are both practicable options . Systemic handling is the best elbow room to manage with other issues .
scurf insect have a knockout shell , making nebulizer - character products uneffective against them . They ingest it as they feed on the plant with a systemic product .
aphid are the most common Schefflera bugs , so treat them with neem petroleum or insecticidal goop .
Most bugs should be easy dislodged with a potent eruption of half-hearted urine . For this , choose a non - drafty location outdoors or inside the rain shower .
You may need chemical pesticides every week if you have a pregnant infestation .
[7] Underwatering
Another potential movement of brown spots on your umbrella plant is underwatering . Your Schefflera ’s transpiration and respiration increment as the days get long , stimulate it to utilize and rout more water .
In addition to increasing the likeliness of your works swim , rebel filth temperatures can also speed up the grunge drying process . As a result , the browning of the foliage backsheesh is a signaling of desiccation .
Other common signs of underwatering let in :
Underwatering is often down to neglect , intense sunlight , or an overcrowded pot ( i.e. , your Schefflera has become root - bind ) .
It ’s a no - brainer : Soak your Schefflera in warm water . Then , ensure to water your plant good until you see urine dripping from the drainage maw .
With any luck , your Schefflera will generate to normal in a few days . Otherwise , you may want to consider run up a container size of it .
[8] Too Much Harsh Chemicals in Soil Due to Over Fertilizing or Tap Water
Your flora ’s brown smudge may also be triggered by a buildup of toxic chemicals like soluble salts , Cl , fluoride , and more .
By damaging the roots , these harsh chemicals reduce the plant ’s power to absorb nutrient and water .
Some of these chemicals are phototoxic , ensue in foliage damage and brown speckle on the leaves .
Excessive fertilizer is to charge if salt scabs seem on the stain ’s surface . In addition , atomic number 17 or fluoride buildup in the tap water can cause brown spots on the foliage , especially on the point and edges .
How to Treat Brown Spots on Schefflera Leaves
The right way to regale brown spot on Schefflera leaves is to identify the implicit in cause . In general , the following measures should be beneficial :
