We use fresh Rosemary all year long for cooking. Tony especially likes to infuse butter with garlic and rosemary for a filet mignon steak sauce. It's wonderful!
I have 3 lovely rosemary plants in the garden. Rosemary is an annual and is not hardy in my climate zone.
I successfully kept them alive last winter in the house and I will do the same this year. Here's how:
First I dug up the plants and shook off as much dirt as I could from the roots. This way I don't bring bug larvae into the house!!
Next I planted them in a box with fresh potting soil. Here are my happy plants in my sun-filled office where they will thrive all winter!
Many herbs are perennials and will return next year on their own. I know my chives, thyme, oregano and mint will greet me outside next spring after a long winter's nap.
