I am growing herbs in containers on my patio this summer for the first time ever. They are doing very well, which is great, but I'm not sure what to do as far as harvesting & storing them goes. Someone told me you shouldn't pick them except for immediate use in cooking until the end of the summer, but if I wait that long to harvest, they may take over my patio! I am using what I can for cooking, but that barely makes a dent in them. Please enlighten me as to when I can harvest, how to do it, ways to preserve, etc. Specifically, I have sweet basil, Italian oregano, garlic chives, rosemary, sage, marjoram, mint, and spearmint. Thanks!
