Cultivation of Rice Paddy Herb

Site: In Vietnam, rice paddy herb is mostly cultivated in flooded rice fields. Because it is grown in high temperatures with high humidity, rice paddy herb cultivation is a true challenge outside the tropics.

Propagation: Get fresh stems from another plant (usually can be found at a Thai or Vietnamese grocer). Place stems in water. Roots will form within a couple of weeks. While they are rooting, they must be covered with a plastic bag (specialty veggie or produce bags work great) to ensure humidity. Place in a shadowy but not dark place as sunlight will kill at this phase.

Growing: When enough roots have been formed, plant the stems into a very tall, clear glass or plastic container filled with soil to cover most of the roots. (You could probably take sheet of thick plastic and make a long tube. That would work too. A mixture of ordinary soil plus small bits of porous clay pots. Keep the plants warm and humid. After a few days, they will able to take intense sunlight or partial sunlight.
