I have a hibiscues plant that keeps dropping its flowers before opening. What is this plant lacking or what is the cause of it shedding its blossoms before the open?
possibly thrips. - though i also have a cranky hibiscus that doesn't like heat and drops its buds all summer. check out www.hiddenvalleyhibiscus.com for a great listing of all the issues that can happen with hibiscus.
