Growing Asian Cilantro

Location

• Vietnamese coriander is a warm-weather loving herb that may be grown as a perennial in USDA zones 9 and 10. The plant may be grown as a summer annual where not hardy. Vietnamese coriander is tolerant of some frost, so long as the duration is brief. For best results, plant in full sunlight in a south, east or west-facing location in the garden. Plant in a sheltered area that offers some protection from the elements.

Soil

• Vietnamese coriander is not picky about soil so long as it is well-draining. Plant Vietnamese coriander in a soil that has a pH between slightly alkaline to slightly acidic. Water regularly throughout the growing season, keeping the soil moist to the touch at all times. Do not allow the soil to become "bone dry," as this will quickly lead to wilt and a decline in the flavor and quality of the young leaves.

Maintenance

• Vietnamese coriander requires almost no maintenance. Like most herbs, the plant is not particularly susceptible to any pests and diseases, although spider mites may sometimes become a problem in hot, humid weather. Spider mites can usually be washed off the plant with a direct stream of water. The plant may be propagated easily by division done in the spring or fall. Young plants may need protection from frost in chilly Northern climates.

Uses

• Vietnamese coriander is grown primarily for its edible leaves, though it may also be cultivated as a bedding or border plant in a cottage garden. The plant's sprawling habit also lends itself to good use as a ground cover. Harvest fresh young leaves in the morning, after morning dew has evaporated but before the sun becomes hot. Leaves picked in the morning retain more moisture and flavor than those picked in the heat of the afternoon sun.
