Why Do My Hibiscus Flowers Only Last One Day. Beside this, why do the buds fall off my hibiscus? Tropical hibiscus flower buds will drop off the plant when the plant dries out too much.

Tropical hibiscus flower buds will drop off the plant when the plant dries out too much. When cooler weather slows the plants' processes, blooms do last longer than during the summer. One of the most common causes of hibiscus blossoms falling off plants is insect pests.

They love sun, but if you are in fla, they would probably do better with a little afternoon shade in the hottest part of the day. Some may linger a second day when the weather is cool. Keep the plant tidy by removing the spent blooms. Try not to think of this as a bad thing, many plants bloom only once a year for two or three weeks and then you have to wait a whole year for a repeat performance.
