Protecting blueberries from hard freezes?
We've had a mostly warm and dry spring here in Vermont but there's a big pool of cold air moving in, and the forecast is calling for temperatures as low as 23F within about a week.
I've got 26 blueberry bushes that are three years old. They are very small, because my first winter I had a bunch of deer gnaw them pretty badly, but they've come back nicely and have quite a few flower buds on them. The buds aren't opened yet, but I'd imagine they'd be getting pretty close to opening by the time the really cold weather hits.
Do I need to do anything to protect the bushes? I realize the bushes themselves won't be harmed, but I've put a lot of time and money into them so far and this was going to be our first real (if small) crop so I'd like to save it if possible.
