Plumeria

Question

We have had our Plumeria for several years and this year the leaves are turning black and falling off. Any ideas about why this is happening? For 5 years they have been doing really good this is the first year and I don’t have a clue and can’t seem to find anything on the internet about it.

Answer 1

This is a severe fungal infection. I would correct immediately with wettable sulfur and dolomitic lime. It seems very advanced, so there is a chance that it will be lost regardless of being treated. Sometimes things like this are unavoidable unless they are caught at the very first sign of infection.

Try this treatment, as it works very well, but like I mentioned... This is very aggressive, and there is a chance that it could be lost.
