Fuchsias are new plants for me. These came with the original garden, and must have survived for several years. The yellowish one is easy to cut back from the neighbours’ path, and doesn’t seem to mind this treatment. The reddish one lost its leaves in a drought last year, but recovered quite quickly. The tips of some branches died over winter and needed pruning in the spring. F4 is rather dry anyway, and needs a lot more organic matter. Both of them would benefit from a fairly severe prune in spring. See RHS advice
