Wilt disease is make by a ground - bear fungus call Fusarium oxysporum . This fungus invades the plant ’s vascular organization , bar the flow of H2O and food . The first mark of wilt disease is usually a single branch or department of the plant life wilting and finally kick the bucket . If left untreated , the disease can spread throughout the total works , leading to its demise .

Powdery mould is yet another disease that hibiscus plants can fall victim to . This fungal infection make a white-hot or gray powdery coating on the leaves , stem , and buds of the plant . It thrives in humid conditions , making it peculiarly problematic in areas with high wet level . Powdery mildew can weaken the flora and stunt its growth if not addressed promptly .
Aphids , belittled sap - sucking insects , are a common pest that can overrun hibiscus works .

Sooty modeling appears as a black , powdery software on the leaves , stems , and bloom , further stymie the works ’s wellness .
Spider mites are another gadfly that hibiscus plants may encounter . These tiny arachnids feed on the underside of leave of absence , causing yellowing , stippling , and eventually leaf bead . They are often found in dry and stale conditions , so it is important to maintain right humidness levels and regularly dust the leaves to prevent infestations .

In my personal experience , I have dealt with wilt disease in my own hibiscus plant . It was devastating to see my once thriving hibiscus step by step wilting and succumbing to the disease . However , through persevering care and implementing the prophylactic measures advert above , I was able-bodied to save some of my plant and prevent further infections .
