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 is used for treating loss of appetite, colds, heart and nerve diseases, upper respiratory tract pain and swelling (inflammation), fluid retention, stomach irritation, and disorders of circulation; for dissolving phlegm; as a gentle laxative; and as a diuretic to increase urine output.
