Answer: 'Anne Arundel' is a vigorous grower that blooms profusely, as you have discovered. Hibiscus are normally propagated by cuttings and by seeds because large plants do not transplant well. Your hibiscus will eventually grow into a screening hedge if allowed to go unpruned. To keep your plant in bounds, cut out about a third of the wood every year - new stems will sprout in the spring. To promote blooms, pinch out the tips of the stems in spring and summer. If your plant is seriously overgrown, remove only one-third of the rank growth each year, expecting that it will take three years to get it into shape. After that, prune annually to keep it in good form.
