Generally, it will take two weeks to see the effects of the treatment, and the effect lasts three to six months. Over time, you may require fewer treatments because weaker muscles atrophy and require fewer injections.
The hibiscus is a heavy feeder that prefers frequent but light fertilizing. A nitrogen fertilizer in the spring and a high potassium fertilizer in the summer work well for the hibiscus plant. Also, fertilizing at the beginning and during the growing season gives the hibiscus needed nutrients for growth.
Hibiscus wilt disease is no different from wilts that affect many ornamental plants. It is caused by fungi with such intimidating names as Fusarium oxysporum and Verticillium.he roots of infected plants do not show any rot except possibly in the late stages of the disease-if the plant survives that long. Once inside the hibiscus, the fungi disrupt the plant's capillary system, preventing water and nutrients from circulating normally.
