The flowers on my honeysuckle form, but then before they open they seems to drop off the stems. This year there were so many flower heads I thought it would be wonderful but now there are only one of two flower heads in flower and they are not complete.I know they don't need watering especially with all of the rain we have had Can you please tell me if it is an insect or a disease. This has happened to every plant to I have ever planted.
