I have developed a growth on the bark of various trees and shrubs in my garden any ideas on treatment or is it best left alone

It's just lichen, won't cause any harm, but if you find it unsightly, you can wash it off gently with a solution of horticultural soap and water, or eco washing up liquid diluted in a lot of water.

Yes I agree its lichen. I think it gives the tree or shrub character. Harmless though :)

Thank you Bamboo and Pam 24 for your help as you say it is not unsightly so I will leave it Many thanks.
