QuestionI live in Minnesota, and was wondering what I care I need to give my sunny border blue for the cold months ahead. Do I need to cut them back? If I do, when is the best time to do that?
Thank you!
AnswerHi Sharon,
Thanx for your question. I do not know what a sunny border blue is. If it is a perennial and hardy to your USDA zone, then just cut it back if it is a plant to about 4 inches above the ground and mulch it with some leaves or pine needles about 4 inches deep. If it is a shrub, I'll need more information, especially if it is a flowering shrub. I hope this helps.
