strawberries & blueberries!!

If you have some small pots and potting mix, you could pot up the strawberry runners now, water lightly,  and keep in a cool place until ready. The roots will oblige by setting while you wait for better weather.

The blueberries, if they're bare rooted, should be potted up in ericaceous (acidic) compost, watered and also placed somewhere cool. If they've started to leaf, then keep them somewhere warmer. If already potted and no leaves, then keep lightly watered and cool until ready. They need a cool spell to do well.

You need to aquire an old bath from a skip and fill it with ericaceous compost and a 3" layer of gravel/polystyrene for drainage ready for your Blueberries to go in equally spaced, once they've established in the pots as Trillium states

Make sure you ask permission from the skip owner or householder first! 

Thanks very much for your advise, like being down the plot but at home, ha!
I'll keep you posted as to how things go! My little girl loves straws and bluebs so hopefully it will go well and save us a few quid.
Cheers
