I live in MN. I plan to over winter my brug in dormant stage in shed at cool temp about 45-50 degrees. The plants are about 6 ft tall. I don't really understand if I should trim now or in spring, and exactly what I should trim. Cut of the branches at the main or only part of the branch? And should it be shaped or just left more stick like?
