Growing vietnamese mint

Vietnamese mint can be planted straight into the garden. Just take a cutting from the parent plant that's got lots of little roots on it. Dig it into a nice, moist soil. It loves soil that's got lots of manure in it and it likes to be cut back all the time, to keep it growing vigorously. Both of these plants will be ready for harvesting in about a month. Fertilise tropical herbs twice a month during the wet season and once a month during the dry.
