Seasoning herbs

Fall: Begin planting cool season herbs before the soil cools off. Plants that thrive in cooler weather are anise, arugula, borage, chervil, chamomile, chives, cilantro, dill, fennel, feverfew, garlic chives, lavender, lemon grass, lovage, parsley, rosemary, salad burnet, sorrel, and tansy. Most nurseries clear out their supply of herbs in the Fall to make room for holiday plants. You may find some nice herbs on sale.
Winter: Take advantage of the cooler weather to plant cool-season herbs or short-lived herbs. e.g. anise, arugula, borage, chervil, chamomile, chives, cilantro, dill, fennel, garlic chives, lovage, parsley, salad burnet, sorrel and tansy.
Spring: When Spring arrives so do the potted herbs at Nurseries. So this is a good time to plant and replace perennial herbs while there is a good supply. The following plants should be in good supply; catmint, catnip, chamomile, chervil, feverfew, lavender, lemon balm, lemon grass, lemon verbena, marjoram, oregano, rosemary, sage, sweet woodruff, tansy, tarragon, thyme, and winter savory.
Summer: Some perennial herbs can be planted in the summer if watered well. The supply of potted herbs at nurseries will be thinning out. e.g. feverfew, lavender, lemon balm, lemon grass, lemon verbena, marjoram, oregano, rosemary, sage, St. John’s Wort, tansy, and thyme.
