I decided that I would start as we mean to go on, so I mowed the lawn, and strimmed the edges, and then got the water feature thingy working! I said to Nikki that when we moved I might get in to this gardening thing.
That said, the garden is better planted than we remembered, so there maybe isn't much to do! There is lots of power in the garden (proper mains cables) so I'm very tempted to put in some really nice garden lighting if I have time - I think that could be really striking...
