Q: Our hibiscus did not bloom this year after doing so for the last four years. It winters in our home and was fed blood meal once in winter and again in early spring.
A: Tropical hibiscus needs lots of vigorously growing leaves in order to flower well. It is likely the nutrients from blood meal have washed out of the soil by now. The rule for fertilizing tropical hibiscus is “lightly but often”. Try giving your hibiscus a half-strength application of water soluble fertilizer every two weeks.
