DATE: 12/25/97 WRITER: Bob Polomski, (864) 656-2604 Growing Herbs on the Kitchen Windowsill Q: I would like to grow herbs indoors during the winter months. Do you have any favorite herbs that will do well inside my kitchen window? A: Herbs that do not do well indoors include sweet basil, lemon verbena, summer savory, and tarragon. These are all poor choices because they either go dormant or shed their leaves excessively. However, with these exceptions most other herbs do very well in a south-facing windowsill. Oregano, thyme, parsley, and sage can all be grown in small pots and trimmed as needed for the kitchen. Pots of rosemary and sweet bay (Laurus nobilis) are equally valuable, though they need more space. In the onion family, windowsill candidates include chives, onion sets and garlic cloves. The onions and garlic can be started in pots. Clip emerging foliage when it reaches a couple of inches high. If you have only an east or west facing windowsill, try mints such as peppermint, spearmint, or lemon balm. Provided they are sheared regularly, these, too, make excellent houseplants. If you find you have insect pests, remember that plants intended for human consumption cannot be sprayed with the pesticides used on ornamentals. Discard infested plants. As for the potting medium, indoor herbs grow best in a mixture of two parts potting soil to one part coarse sand or perlite. Setting the pots in trays lined with gravel will keep them from getting wet feet should you overwater. Cool temperatures (60 degrees F), especially at night, will keep herbs at their best. ************************** If you, have gardening questions or comments, write to Agricultural News and Publications, A-101 Poole Agricultural Center, Box 340311, Clemson University, Clemson, S.
