I have two lemon trees and an orange tree at the foot of my garden on a lower level. I would like to put in a retaining wall and fill the area with soil, which would mean having the soil possibly up the trunks of the trees to a point 60 cms above where it is now. Will this damage the trees?

It is possible it will damage the trees. That much soil could suffocate the roots below and make it difficult for the trees to survive.
