Here's what I did.
- Placed four stakes inside pot to use as support.
- Wrapped pot and plant with burlap using twine.
- Stuff inside the hole tons of leaves and all around the rosemary between the burlap to insulate it. I even put leaves between the burlap and the pot.
Tips: Put your pot on the ground instead of an unnatural surface. Keep your pot in a sunny spot. Make sure your plant is in a big pot. Don't use saucers. Use a pot that is thick walled. Cut off any dead branches or diseased looking ones.
