We don't have blueberries... we tried a couple of years ago, but (my bad...), I had Tony put a bunch of sheep compost/manure in with them, which promptly burned them to death.
I think your plan sounds great! Today I hope to pot up some dahlia bulbs (bulbs or tubers??). I'm hoping we didn't lose anything, but it's too soon to tell. My potted wisteria has made it through winters past, but I have yet to see new growth. Don't know about my potted mystery vine (I can't remember what it is now... trumpet vine or crepe myrtle???). That one was not happy at the end of last season, so I don't know if it will come back. Everything else is looking good!
