Frangipani Leaf Problems. Lately my inbox has been flooded with cases of frangipani rust. It is most noticeable in late summer and early autumn.

I have a plumeria frangipani that is showing spots on the leaves and some curling of leaves.
If you notice spongy stems remove the stem completely to the junction with a main branch. Fortunately the disease only affects frangipanis. Frangipani trees plumeria spp produce the fragrant blooms found in hawaiian leis. A bit easier to contain than frangipani rust.
