Answer: Tropical hibiscus blooms on new shoots and generally take about 3 months of growth after they have been pruned. If it has been longer than that, and if your plants are getting full sunshine and adequate water, they may need to be fed. Try a bloom booster that is high in phosphorous. If it is a water-soluable fertilizer you can use a half-strength dilution and feed every 2 weeks during the summer months. Hope this information helps!
