What causes the grey, mossy fungus on my hibiscus shrub?

Our Advice:

This is lichen, which often mistaken for a fungus but actually a small plant that lives harmlessly on another plant. The appearance of lichen on plants is often an indicator that growth is slow and they lack vigour, particularly on older trees and shrubs. Feed your hibiscus with a general fertiliser in the spring to improve the growth.
