White powdery stuff on trunk
About 6 months ago a friend gave me a potted cutting that she got from a nursery as a gift. Unlike the other 2 potted frangipani (sorry I'm Australian) cuttings I have on the same balcony it hasn't really grown.
On closer inspection I have now noticed it has white powdery clusters on various parts of the trunk and in cases this looks like it is sitting on a sore/ulcer type wound on the trunk.
I live in an apartment so growing in a pot is my only option. Could it be a drainage issue? There have been no leaves so I can't check traditional indicators of wet feet such as black soot or mould on the leaves that I would look for on other types of plants.
I live on the Gold Coast so its almost summer all year round, they get sunlight every day but not all day. I don't think I am over watering them as the other do are doing well but obviously there is a problem.
Any advice would be hugely appreciated
