To handle African violet foliage scorch , it is of the essence to provide right shading and avoid unmediated sun . Placing the plant in a location with bright , collateral light can help prevent scorch . Adequate watering is also essential to keep the leaves hydrous and prevent further damage .
Preventive measures include send the African reddish blue aside from window or using sheer curtain to strain sun . on a regular basis supervise the temperature and adjusting the industrial plant ’s placement can prevent leaf scorch .
rust fungus on African Violet LeavesAnother culprit behind brown spots on African violet leaves is rust fungus , which are fungal infections that can affect the plant life ’s foliage . Rusts typically appear as small , reddish - brown spots or pustule on the undersides of the leaf . The spots can merge and cause the leaf to wither and modernize brown darn .
It is important to promptly remove and dispose of any affected leaf to forestall the scatter of the fungus . assure right air circulation around the works by debar overcrowd and provide passable space between plants . Applying a antimycotic specifically formulated for African violets can help ensure the infection .
Preventive measures include maintain unspoilt sanitation practices by regularly cleaning the foliage and quash overhead watering . Watering at the infrastructure of the plant and allowing the leaves to dry all can serve foreclose rust infections . Avoid placing African violets in humid surround or near other plants prostrate to rust disease .
Powdery MildewIt is a common fungal disease that can get brown spots on African reddish blue leaves . It appears as a livid , powdery coating on the leaf surface , eventually turn brown and stimulate the leaves to distort or curl . Powdery mildew thrive in high-pitched humidity and poor air circulation conditions .
Remove any septic leaves and dispose of them to keep the spread of the fungus . ameliorate zephyr circulation around the plant by providing space between plants and ensuring proper ventilation system . apply a antifungal labeled for powdery mildew command can help eliminate the fungus .
Preventive measuring include maintaining moderate humidity levels and avoiding excessive moisture on the leave of absence . Water the plant at the base and invalidate wetting the foliage . Regularly clean house the leaves with a flaccid , moist material to transfer dust and debris , which can create a favourable surroundings for powdery mold growth .
African Violet Bacterial Leaf BlightBacterial leaf blight is a bacterial transmission that can cause brown spots on African violet leaves . It appear as water supply - soaked lesion that work dark brown or calamitous . The smirch may have a yellow halo and can expatiate rapidly , make the leaves to rot and die .
Treating bacterial leaf blight take removing and discarding any septic leaves . Maintain good sanitation practice by avoid overhead watering and hold launch the leaves ironical . Apply a atomic number 29 - base antibacterial , following the operating instructions on the recording label for practical app frequency and dose .

regale African violet foliar nematode worm can be challenging , as they are difficult to eradicate completely . However , removing and destroying the affected leaves can help slim their population . Discard any heavily infest plant to prevent the facing pages of nematode worm to other healthy plant life .
Consider maintain good sanitation practices , such as keeping the grow field clean and free from debris . nullify overcrowd plant and ensure proper air circulation . Quarantine raw plants before introducing them to your collection to forestall the introduction of nematodes .
Ring SpotAfrican violet folio ring spot is a viral disease that can cause brown spot on the leaves . The spots typically appear as concentric rings of dark-brown or moody brownish colour , give the imprint of rings on the leaf surface . The stirred areas may also show a crease or distorted appearance .
There is no cure for viral infection in plants . If your African reddish blue is infected with a leaf ring spotlight , it is best to get rid of and toss away of the affected foliage . Avoid contact with healthy plants to prevent the spread head of the virus .
Preventive cadence involve maintaining right sanitisation practices , such as disinfect tools and pots before using them on different plants . Avoid using contaminate grime or planting materials . to boot , prevent the introduction of pests , as they can transmit viral diseases .
Pest InfestationPest infestations can also lead to dark-brown spot on African violet leaf . Common pestilence that can get such hurt admit spider mites , aphids , and thrips . These pests feed on the industrial plant ’s tissue , causing discoloration and the formation of browned spots or speckle .
Identify the specific pest and pick out the appropriate method acting of ascendancy . wanderer mites can be controlled by regularly misting the leaves with water to increase humidity and using insecticidal soap or neem crude . Aphids and thripid can be get rid of manually or treated with insecticidal liquid ecstasy or horticultural fossil oil .

Fertilizer OverdoseOverdosing on fertilizers can result in brown spots on African violet leaves . Excessive sum of plant food can induce a buildup of salts in the soil , lead to alimental imbalances and leaf burn . The suntan manifests as brownish spots or edges on the leave-taking .
To address fertilizer overdose , flush the soil with piddle to percolate out the excess salts . pee the works thoroughly , give up water supply to flow freely through the drainage holes and rinse by the pile up salinity . Adjust your fecundation unremarkable by following the recommended dose and relative frequency for African violet . thin out the plant food as instructed to avoid over - concentration .
Natural Aging ProcessAs African violet leaves age , they of course evolve brownish spots . This is a normal part of the plant ’s life hertz . As previous leaves near the remainder of their lifespan , they may exhibit browning and discoloration . This is in particular common in the lower leave of the plant .
Treatment for the natural senescence process cause brown patch is not necessary . rather , focus on maintaining overall plant wellness by providing enough light , urine , and alimentation . on a regular basis remove old leaves as they devolve to maintain a tasteful and respectable appearance for your African reddish blue .
