A new raised bed for blueberries

[Pumkinpie]

As I mentioned in a previous post most of my blueberries in the pots managed to survive the winter.
I have made a raised bed for them down the side of the shed so the run off will help water them.
I have put a thick layer of bark chippings under some lime free compost. I hope this is alright as I really didn't know what to bulk out a lime free bed with.
I would normally use mushroom compost in my raised beds but didn't as lime is used when growing the mushrooms. Oh as a side I noticed I have got some mushrooms sprouting where I put the mush compost. I will however check they are edible ones you just can't be too careful with mushrooms.
Looking forward to some yummy blueberries the plants are loaded with flowers.
