While many of our garden herbs overwinter successfully, others are quite tender. One herb worth bringing in over the winter is lemon grass, because it can be hard to locate in grocery stores. The tasty shoots add a hint of summer to many dishes and tolerate the warm indoor temperatures quite well. Simply dig up several stalks and transfer them to a large, heavy container. The grassy leaves can be trimmed back to make the plant tidier indoors. Transplant enough stalks to provide a winter supply as well as a few stalks to return to the garden next season. Place containers in a bright, warm location away from cold drafts and water sparingly. Do not expect much growth over the winter months.
