Hi: I planted a trumpet vine 3 years ago and each year after blooming, the leaves begin to yellow, brown, and then fall off. Per recommendation from a local nursery, I have tried a fungus spray, increasing water, decreasing water, and various fertilizers with no luck. Does anyone know what may be wrong with my vine? Thanks!

Update: Based on research on this site it may actually be a Honeysuckle vine....but problem is still there!

Hi Diane,

Both Trumpet Vine (Campsis radicans) and Honeysuckle Honeysuckles (Lonicera) are deciduous vines and will usually lose their leaves in the fall but I'm sure climatic/weather conditions as well as insect/pest damage can cause early leaf drop as well.

There are fungal diseases that affect Lonicera: http://homeguides.sfgate.com/h... and I wonder if perhaps your plant might be suffering from fungal leaf blight? https://www.google.com/search?...

This page gives information on control of the leaf blight: http://nac.unl.edu/documents/d...

Hopefully others more knowledgeable with Lonicera will be able to offer advice and tips.
