I am a complete gardening novice, but at the age of 41, have decided that I would like not to just look at the garden, but get a bit more involved. This started only a few months ago, so it is all still very new to me. We have two raised beds that we have earmarked for fruit bushes or veg. It is against a fence (with clematis growing up it), east facing, but has huge amounts of sun and the area around it is not built up. We live in the south east.
We already have rhubarb growing in there, but we'd like to grow other things too. The bed is empty, but will need some prep I'd imagine (I have no idea what - all advice very welcome indeed).
What can we grow that has a large chance of success and is low maintenance please? I would like us to eat whatever it is that we grow, so I suppose I am looking at fruit or root vegetables and that rules out gooseberries and black/redcurrants.
