Mickie, at that 2.5 size are you doing somethng to protect the root zone from alternate freezing and thawing in the winter?
I put the plants in those pots as a temporary emergency measure. That size is easy to move about. The soil is a mix of potting mix and pine bark mulch. I added acidifier, and have kept them watered. Monthly they get fertilized with azalea fertilizer. Of the 19 plants, I expect about half to be worthy of saving... some are just struggling along... they were iffy to start with.
For the winter, once they go dormant, I can store them in my basement, but am unsure about any care during that dark 45-55 degree time. Can they be allowed to go dry?
My other question concerns winter after they go into permanent 12-15 gallon pots... is that enough to just leave them? I have 4 decorative 1/2 barrel pots for the Sunshine Blue & Tophat varieties, and 15 gallon pots I intended to sink into my crappy ground. My original intent was to line my long driveway with in-ground hi-bush blueberries and raspberries, but now, I think I would need to get someone to backhoe a trench for that.
This is a learn-as-I-go endeavor... any advice for this fickle climate zone is much appreciated.
