Rosemary outdoors for the winter?
I live in northeastern Pennsylvania. I've had a rosemary plant now for many years, given as a gift. I've been digging it up year after year, brought in for the winter. It does very well in my garage with morning sun and cool temperatures. My question is, it's getting too big, about 3 feet high and wide. I'd really like to leave it outdoors this winter. My thought was to mulch heavy, and put some burlap around the bottom. It's a few feet from the house, protected by a deck. I really hate to lose it, but even with cutting it back it's too large to be brought inside. Has anyone had success with leaving outdoors in the winter, any tips would be greatly appreciated. This plant is around 20 years old.
