Tips and Instructions

  1. 1
    There are perennial herbs that overwinter well
    Examples are chives, oregano, lavender, and thyme. But in areas where winter is extremely cold, add, for extra protection, two to three inches thick layer of shredded bark mulch. The herb roots will be less likely to heave out of the ground, desiccate, and then die because of the presence of the bark mulch. It will thus prevent the ground from freezing and thawing in winter.

  2. 2
    Bring the plants indoors for the winter
    Tender perennial herbs like rosemary and biennial herbs like parsley could be potted up and brought inside for the winter. Here's how to do it:
    1. Dig the parsley plant and make sure you take most, if not all of its root system.
    2. Pot the parsley plant in a deep container, water abundantly, and leave for a few weeks outdoors in a shaded area. Putting the plant back outdoors (but in the shade) will make it adjust to transplant shock. When revived, bring the plant back indoors before a hard freeze and locate it near a window exposed much to the sun. By autumn, if you potted a lot of parsley, you will have a fresh harvest! If they have enough light, they will even produce new growth. By late winter, leaf quality will not be so good as parsley gets ready to produce seed stalk. By that time, compost the plant.

    For rosemary varieties, you have to bring them indoors before a hard freeze
    After potting up, allow adjustment to the plant for container life. Place it near a window with lots of sunlight. Rosemary is an herb of contrasting characteristics. It likes cool temperatures, but it is also adaptable to high humidity and likes to thrive in barely moist soil during winter.

  4. 4
    For rosemary, when indoors, should be kept in temperatures of 50-60 degrees Fahrenheit
    Humidity could be maintained by misting often. The pot should be placed on a pebble tray filled with water. Water does not really need a lot of water. Just water it enough to keep the soil from drying out.

    The rosemary might not grow much in winter, but with these guidelines, it should survive beautifully
    An added benefit would be the unique fragrance and taste of rosemary will stay with your kitchen the whole winter season.

    For your use, not primarily their protection, you can bring into the house for winter hardy herbs such as oregano, thyme, and mint
    Put them in pots to provide fresh leaves for your cooking while the snow is raging outside. When spring comes around, simply plant them back into the garden.

However, those people who are leaving in extremely cold locations during the winter season, they should incorporate extra protection, preferably 2 to 3-inch thick layer of bark mulch (shredded). Because of the bark mulch, the roots of the herbs are less likely to upraise to the ground and dehydrate. The bark mulch will avoid the ground from thawing and freezing in winter.
