Don’s Expert Answers: My pittosporum trees have chalky spots on the trunks, also after 3 years they are now 3 metres tall but i noticed this year the leaves are thinning out and dropping off, now they are not as thick and bushy. I could not see the fence now it is visible, some of the trees are now growing a pea on the small branches as the leaves are being replaced by them. The main issue I have is that they are not as thick as they were last year, the leaves do still look healthy though even the a lot have disappeared from the branches.
