Asparagus won't be showing yet, last year I recorded the first shoot coming through on 25th April - others here had some a few weeks earlier than that. Blackcurrants have buds on, so do gooseberries, but these weren't open at the end of March last year, although I've got a photo at the end of April showing them in full leaf and flowering. So don't give up, there's plenty of time. Unless of course there aren't any buds at all on the fruit bushes, in which case they might not be alive. Scratch a little of the bark away from a blackcurrant or gooseberry stem near to the soil with your thumbnail, it should be green/white underneath, if it's brown, it's dead.
