Hot Tropicals !
Strange as it seems, even tropical plants suffer in excessive heat. Recently a client asked me about the Hibiscus in her containers. She commented that "they all seem like they are going to bloom but most of the the time the buds just break off and die before they even bloom." Even though Hibiscus are tropical they are temperamental if they get too hot. "Bud Drop" is a sign of stress. It is occasionally a problem, especially during excessively hot weather. Hibiscus grow best in daytime temperatures ranging between 75 and 85 degrees Fahrenheit. Temperatures over 95 degrees will often cause most flower buds to drop off. Hibiscus can survive temperatures even as high as 115 degrees, provided they have adequate water. When the weather is hot, it is best to maintain a steady supply of water to the plant, rather than have it go through wet/dry cycles. These containers have an automatic irrigation system so water has been fairly even. There is a lot of radiant heat on this site from brick buildings and the patio. It is also protected from wind so this outdoor room can really heat up. I suspect that radiant heat is the problem even for this sun-loving tropical.
