I have a frangipani which leaves turn yellow and have black spot on them am i doing something wrong?

Frangipani are usually very hard and not prone to the insects and diseases like some plants. Ordinairly I would believe it's a matter of poor drainage.


The yellow leaves usually indicate that.


The black spots I don't know.


Rust sometimes attacks the frangipani

I have a frangipani which leaves turn yellow and have black spot on them am i doing something wrong?
Frangipanis normally drop their leaves in the fall (they are deciduous). If you are in the southern hemisphere that would explain the leaf drop, which might be accompanied by some leaf spotting as the leaves senesce.


If you have a tree starting to sprout out new leaves for spring, and they are spotting and falling off, the plant could have gotten a touch of cold, or you may have salt build-up in the soil. Salt build up is most commonly caused by over- fertilizing, but can be caused, over time, by not watering thoroughly enough for water to run out of the drain holes in the bottom of the pot. This can be quickly corrected by watering the plant repeatedly (5 or 6 times) so that water flows freely out of the bottom of the pot several times. Good luck.
