Blueberry buds

My two blueberry plants survived the winter. They are small plants, meant to be grown in containers. I bought them from the nursery that makes my hometown famous, Stark Bro's in Louisiana, Missouri. Their advice was to put the plants in a garage in the winter if it stays just a bit warm, but our garage is both very full and very cold in the winter. So, we tried burying the pots. It worked!
