Chives

Allium schoenoprasum

A hardy perennial allium that returns every spring, tolerates shade and poor treatment, and needs almost nothing done to it. The flowers are edible and among the best early nectar sources in a vegetable garden. For a grower who wants one permanent herb in a pot that will still be there in five years, this is the one.

Position: Full sun or Partial shade
Water: moderate demand
Drainage: Moisture-retentive, Free-draining
Grows to: 20–30 cm × 20–30 cm
Hardiness: H7
Harvest: March to October
Difficulty: Straightforward

What kind of herb this is

Herbs are a kitchen grouping rather than a botanical one, and the plants in it want opposite things. This is the one distinction that decides how to treat it.

Wants damp ground and tolerates shade, which is the opposite of the Mediterranean set. Most will spread if allowed to, so the question is usually containment rather than establishment.

Almost any herb will sit on a windowsill in July. This is about whether it is still there in March, which is the part a pot on a supermarket shelf does not tell you.

What happens when it flowers

On a herb this is rarely a problem and rarely nothing. It is the point at which the plant stops being what you grew it for — by a lot, a little, or not at all.

Growing it

HarvestingCut leaves with scissors about 3 cm above the base, taking a section of the clump at a time rather than trimming all of it. Cut chives regrow within a few weeks.
PropagationLift and divide the clump every two or three years in spring or autumn. A congested clump loses vigour, and division is how a single plant becomes the several most kitchens need.
PruningCut the whole clump back after flowering for a fresh flush of tender leaves. Remove the spent flower heads unless you want seedlings — chives self-seed freely.
WateringChives want steady moisture and show it plainly: the tips go brown and papery when the clump is dry, and the leaves turn thin and wiry. Water the ground rather than the foliage and keep pots from drying out entirely, which is the usual fate of a chive pot on a sunny sill. They tolerate ordinary garden conditions well, so this matters mainly in containers and in a drought.
FeedingA clump in decent ground needs nothing. A clump in a pot, being cut several times a season, does: give a balanced liquid feed monthly through the growing season, or repot into fresh compost each spring, which is simpler and works better. Chives that come back thinner every year are usually starved and congested rather than diseased — lift, divide and replant them.
PlantingPlant in spring or autumn in sun or light shade, in soil that holds moisture, setting the clump at the depth it was growing. Chives are among the best herbs for the front of a bed or the edge of a path, and a plant near the vegetable garden earns its place for the June flowers alone — they are worked heavily by early bees.

The bud you cut to becomes the new shoot, and it grows in the direction it points — which is why an outward-facing bud opens the plant up and an inward-facing one crosses the middle.

The rule is the same in all four: the new piece needs both a growing point and roots of its own. A cutting is the exception that has to make its roots afterwards, which is why the node matters so much.

Is it worth putting under cover?

Whether it will grow there is on the methods table above. This is whether the space is well spent, which is a different question and usually the one being asked.

Productive from roughly March to October and not after. Growth stops when the light does, and a plant pushed through the dark months usually does not recover. Dormancy. Chives want a winter rest and go yellow and thin if kept warm and cut through the dark months; a pot rested cold and dry returns properly in spring.

Growing it without soil

Nearly anything can be grown in a soilless system by somebody with enough equipment. The useful question is whether it is worth it, in which technique, and what goes wrong.

Grows readily, but chives are a hardy perennial that expects a winter. Treat an indoor clump as a one-season crop rather than a permanent planting.

Techniques that suit it

Deep water cultureRoots hang in aerated solution. Very productive and very unforgiving of solution temperature — warm solution holds less oxygen and root disease follows.
Drip-fed mediumSolution is dripped into an inert medium around each plant. The most forgiving technique and the one that suits large, long-season, heavy crops.
Ebb and flowA bed of inert medium floods and drains on a timer. The medium holds moisture between floods, which makes it far more tolerant of interruption than NFT.
