We inherited an established hibiscus which is 2m x 2m (6ft x 6ft) and in a sunny position. In the past two years, it has come into bud, but these did not open. It produces a lot of leaves, but I want to get rid of it, while my husband says that all we need is a hot summer. If we keep it, how can we encourage it to flower?

Answer:
Your husband is quite right. Hibiscus generally require long, hot summers to perform well and produce the spectacular display of exotic flowers for which they are grown, so keep your fingers crossed!

In the meantime, ensure that your specimen is being cultivated in the correct conditions. These plants prefer moist, humus-rich soil and a sheltered position in full sun. Help it along by watering regularly and, during the growing season, feed once a month with a balanced liquid fertiliser. An organic mulch around your plant will also help to keep the soil moist and improve its nutrient content.
