Harvesting Herbs from Your Garden
Throughout summer, snip plants regularly to encourage branching and new growth. Harvest successive cuttings whenever you need fresh herbs. Generally, cut no more than one-third of the stem's length. Exceptions include chives and lavender: When they bloom, harvest the flowering stems at ground level. Use the snippets of culinary herbs in cooking. Use other fresh herbs to make bouquets and teas or for a delightful herbal bath.
Gather herbs early in the day, after the dew has dried but before the sun bakes the plants' essential oils. If you're harvesting an herb's leaves, cut the stems at their peak, when the flowers start to form. If you like, gather the blooms of herbs when they develop fully. If you're after an herb's seeds, wait until they mature and begin to turn brown before harvesting the seeds heads.
To prepare leafy stems for use in cooking, strip the leaves off the stems by sliding your thumb and forefinger from top to bottom. Snip off thicker leaves, such as those of parsley, bay, or tansy, which don't strip off readily. If you plan to remove the herbs before serving the food, skip stripping and use whole stems. Tie them together for easier removal from whatever you are cooking.
The traditional way to preserve herbs entails gathering small bunches of 10 to 15 stems and hanging them in a warm, airy place to dry. Wrap stems tightly with a rubber band or tie them with twine. Hang the bunches on a drying rack, on the rung of a hanger, or from a nail. Drying can take up to three weeks, depending on the plant and its moisture content. Strip crisp-dry leaves off stems before storing them. Dry seed heads by placing a paper bag over them and tying it shut around the stems. Place only one type of herb in each bag and label it. The seeds will drop into the bag as they dry. Let seeds dry for several weeks before storing them properly.
Store dried herbs in airtight glass or ceramic containers away from light and heat (never on or near the stove) to protect their flavor and fragrance. Keep the leaves whole until used (crushing leaves releases their flavor). Use dried herbs within a year of harvesting.
