Planting Situation is best in full sun. But In very hot regions a little shadow in the late afternoon is good. Rich moist fertile well drained Soil. Because of their rapid growth they need good feeding high N,K,P plus magnesium. and water in the growing season. we use Tomato or Gerainium. feed this is available in crystal form to disolve in water or in granules. It is obgliatory to put a deep layer of straw or leaves over the roots and around the stems, in winter, to protect against the hard frosts. Wait until spring before cutting the old dead branches. Which will mark the location in the spring for watering etc. You can cut the old wood very short but I advise you to leave 5cms. Hibiscus start growth around mid may quite late.Hibiscus MUST have a period of cold in order to be healthy, and to make a good start in spring.
