Propagating Herbs
Herbs are easy to grow. Once established, they are virtually insect and
disease free and have aromatic and culinary uses throughout the year.
However, even among the most popular herbs, there are problems in
obtaining the desired variety or starting the plants at home.
Many Must Start from Cuttings or Divisions, Not Seeds
Many of the most desirable herbs are best started from cuttings or
divisions. Cuttings grow much faster than seed with some plants,
such as rosemary, and may be the only option for getting the aromatic
varieties of other plants. For example, French tarragon is the
only variety that provides the aromatic oils that impart the
anise-like flavor in prized recipes, but it does not set viable
seed. If you've been disappointed in the plants you started
from seed or even those purchased at the nursery, it's because
they were Russian tarragon, a sad cousin to the culinary herb.
Most oregano varieties sold from seed also lack enough aromatic oils
for culinary purposes so you must be very careful in your source or
start from cuttings.
English thyme is a female plant and only produces hybrids if grown
from seed. Therefore, the characteristics would differ slightly
depending on the source of pollen. A true English thyme would
have to be started from cuttings. Herbs to grow from cuttings
include lavender, oregano, peppermint, pineapple sage, rosemary,
English thyme, lemon thyme, and tarragon.
Chives, Tarragon, Oregano Among Those Best To Divide
If you or a friend already have an established planting,
dividing it is the fastest and most successful way of starting
many perennial herb plants. Spring is generally the best
time to divide herbs or other perennials. The older plant is
dug, the soil shaken off, and the clump divided. Plants, such
as chives, can simply be pulled apart. Woodruff, tansy, and
tarragon need to be cut into sections. Others, such as the
mints, oregano, and lady's mantle, can be carefully separated
into individual plants. Replant each new plant at approximately
the same depth it was growing originally and water thoroughly.
Herbs that grow from divisions include chives, tarragon, beebalm,
catnip, horehound, oregano, peppermint, sweet Woodruff, lady's
mantle, and tansy.
