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 grows flower buds at the end of new branches, so you'll get more blooms this way. Give it a rest. Keep your hibiscus cool in winter (about 60Â°F/16Â°C) and allow soil to dry out between waterings. Growing hibiscus indoors is a little work, but worth it. You'll be rewarded with big, gorgeous flowers in vibrant colors. With good care, you'll enjoy your flowering plant for many years.
