The Garden Rescue team face one of their biggest challenges ever in Witney, Oxfordshire. Amy and Chris's garden sits at the bottom of a steep bank and is shaded by a mass of trees. Charlie and Chris both come up with woodland-inspired designs to tackle it, with Charlie coming out on top. But before anything pretty can be done, the landscapers have to secure the sloping bank and level the lower part. This impressive feat of engineering enables Charlie to realize her natural vision that includes a stunning water feature and beautiful terraced borders.
