This summer I started growing blueberry plants (year old plants, I assume) in pots to determine if they would thrive before transplanting them to my garden. The first frost in this area (morthwest Missouri) is expected soon. (1) Should I move them indoors this winter? Will being in pots make them more susceptible to winter damage if I leave them outdoors? (2) When should I move them -- when they drop their leaves? (3) If I move them indoors, will they need any sun/water during the winter?
