how do i get rid of ants and pests (green fly eggs i think) from my young apple tree without harming the tree? I have tried water and washing up liquid spray.

I would put a band of masking tape around the trunk of the tree, and put a thick row of petroleum jelly on the tape. That will stop the ants from climbing the tree. to get rid of the greenfly, keep spraying with the washing up liquid solution. The key when using soap to kill aphids is persistence--any you miss with one spraying will fill the tree in a week or two. Spray every day for three days, every other day for 6 days, then twice a week.
