I need some advice. For the first time I over-wintered brugs in an unheated room in my basement. They were cut back (20" or so) in the fall and left in pots which I watered sparingly over the winter. They had natural daytime light. They are starting to sprout and I would like to know the best way to reintroduce outdoors. It's still a little on the cool side (50-60 during the day and 30-40 at night) but I am chomping at the bit. Advice?
