The Q&A Archives: Tropical Hibiscus

Question: My tropical Hibiscus buds, but they turn yellow and fall off before bloom. What can I do about this?

Answer: Premature flower bud drop is often a problem with hibiscus. Some varieties, especially some doubles, are characterized by premature bud drop. Some varieties bloom well during one period of the year and consistently drop their buds at other times. Bud drop can also be caused by insects such as thrips or caterpillars. Nematodes, nutritional deficiencies, overfertilization, and environmental factors such as poor drainage and excessive water, drought, or salt spray can cause flower buds to drop.
