I have a conifer tree (potted) on my patio that seems to be suffering very badly. I have been told that the tree needs lots of water and I have given it plenty but with no results. The tree seems to have gotten progressively worse over the last 6 months. I am moving to a house soon and I had intended to plant the tree in the garden however I am wondering if this would be a wasted exercise or if the tree is even salvageable at this stage? Any advice would be greatly appreciated. I have attached photos of the tree in question.
