French tarragon care starts with giving this perennial herb a sunny place, a roomy
container, and soil that drains freely. French tarragon (Artemisia dracunculus var.
sativa) is prized for its aromatic leaves, but it can struggle in waterlogged soil
and may die back in winter. With the right pot and seasonal care, it can provide
fresh leaves for cooking for several years.

## Choose a pot and soil that drain well

To grow tarragon in pots, start with a container at least 12 inches wide and deep
for one plant. A larger pot gives the roots more room and dries out less quickly
in hot weather. Make sure the container has drainage holes. Decorative pots without
holes can hold excess water, so use one only as an outer cover for a draining nursery
pot.

Use a quality potting mix rather than garden soil, which can compact in a container
and drain poorly. A mix intended for herbs or vegetables is usually suitable. If
it retains water for a long time, blend in perlite or pumice to improve drainage.
French tarragon drainage is especially important in cool, rainy conditions, when
the plant uses less water. A layer of gravel at the bottom of the pot will not correct
poorly draining soil; the pot itself and the growing mix need to let water escape.

French tarragon prefers moderately fertile soil. Avoid mixes that are heavily enriched
with manure or slow-release fertilizer, since excessive nutrients can encourage 
soft growth and may weaken the flavor of the leaves.

## Give tarragon sun, with some afternoon shade in hot weather

Tarragon sunlight requirements are straightforward: aim for at least six hours of
direct sun a day. In regions with intense summer heat, a spot with morning sun and
light afternoon shade can help prevent the plant and its pot from becoming stressed.
A container is useful because it can be moved as the seasons change.

Good air circulation helps foliage dry after rain or watering. Avoid crowding the
plant against a wall or among dense greenery. Tarragon can tolerate some light shade,
but too little sun often produces weak, leggy growth and fewer usable leaves.

## Water when the soil begins to dry

Tarragon watering is easiest to manage by checking the pot rather than following
a fixed schedule. Feel the top inch of soil. If it is dry, water thoroughly until
excess runs from the drainage holes. Empty any saucer beneath the pot so the roots
do not sit in standing water.

The plant needs more frequent checks during hot, windy weather, especially in a 
small container. In cool weather, it may need water much less often. The goal is
evenly moderate moisture during active growth, not constantly wet soil. Wilting 
can signal dryness, but it can also occur when roots have been damaged by excess
water, so check the soil before watering again.

Yellowing leaves, soft stems near the soil line, and persistently damp potting mix
can indicate tarragon root rot. If the roots have begun to rot, adding more water
will make the problem worse. Move the plant to a brighter, airy location, let the
mix dry somewhat, and check that the drainage holes are clear. If much of the root
system is dark, soft, or foul-smelling, the plant may not recover.

## Harvest leaves without exhausting the plant

You can begin light harvesting once the plant has established and produced plenty
of leafy growth. Snip leafy stem tips with clean scissors, taking only what you 
need. Regular light trimming encourages branching and keeps the plant compact. Avoid
removing most of the foliage at once, particularly early in the season, when the
plant is building strength.

Use fresh leaves soon after cutting, or store them briefly in the refrigerator. 
French tarragon has a distinctive anise-like flavor and is a classic seasoning for
sauces, eggs, chicken, and fish. Its flavor is delicate, so add it near the end 
of cooking when you want its aroma to remain noticeable.

## Divide tarragon to renew an older plant

French tarragon is usually propagated by division or stem cuttings. It rarely produces
viable seed, so seed packets labeled tarragon may contain Russian tarragon, a different
plant with a less prized flavor. Check the plant’s identity before buying if you
want culinary tarragon.

When a container-grown plant becomes crowded or develops a declining, bare center,
lift it in spring and divide the healthy outer portions. Each division should have
roots and living shoots. Replant divisions in fresh, well-draining potting mix and
water them in. A plant that is vigorous and still has room in its pot does not need
dividing on a fixed schedule.

Stem cuttings are another option. Take healthy, nonflowering shoots, remove the 
lower leaves, and place the cuttings in a moist, free-draining rooting medium. Keep
them in bright, indirect light while they develop roots.

## Overwinter French tarragon in a container

French tarragon dies back or becomes dormant in cold weather. In areas where it 
survives winter in the ground, its roots may still be more exposed in a pot, which
can freeze more quickly. In a mild climate, the container can often remain outdoors
in a sheltered spot. In colder regions, move it beside a protected wall, place it
in an unheated garage or cold frame, or insulate the pot to reduce temperature swings.

During dormancy, water sparingly. The soil should not remain wet, but it should 
not become completely dry for long periods. Avoid bringing the plant into a warm,
dark room, where it may produce weak growth. In spring, return it to a sunny location
and resume watering as new growth appears.
