Black Marks On Frangipani Leaves

Q:

Hi Don,

You very helpfully informed me how to deal with Frangipanis cuttings,but now the leaves are starting to develop black marks on the leaves.

I have got them in a glass greenhouse to emulate their Mexican homeland, as the weather in England is unpredictable.

Any chance you can help me out with this one?

Thanks in advance,

Simon Roome

Hi Simon,

I can only guess that a combination of low light levels, cold snaps and too much water are the causes. REMEMBER that Mexico is mostly DESERT! High humidity will kill Frangipanis in cold climates.
