2. Top 3 How to Grow Vietnamese Coriander

Vietnamese coriander is semi-aquatic, so you can grow it from cuttings in pots or hydroponically. Below are detailed instructions for each method.
 

2.1. How to Grow Vietnamese Coriander in Pots


Looking for a way to grow Vietnamese coriander from cuttings in pots? Try the following method:

Step 1: Preparation
 

  • Use trays, pots, foam boxes, or large plastic bottles. Reuse old items to save costs, especially if you live in a rural area.

  • Ensure the pots have drainage holes to prevent waterlogging. Although Vietnamese coriander prefers moisture, it must not be waterlogged.

  • Soil: Mix 50% soil, 30% worm castings, 20% coconut coir or dry rice husks, and a bit of sand if possible. Preparing the soil about a week in advance improves its quality.

  • Choose cuttings: Select thick, healthy cuttings from the lower part of the plant.


Step 2: Planting Vietnamese Coriander from Cuttings
 

  • Choose cuttings that are mature, healthy, and about 15 cm long with 5-6 nodes.

  • Insert the cuttings directly into the prepared soil. Ensure the cuttings are buried about 2/3 of their length (i.e., 10 cm in the soil and 5 cm above the surface).

  • Space the cuttings 10 cm apart to allow for optimal growth, as Vietnamese coriander is a creeping plant.

  • Firm the soil around the cuttings, keep them upright, and water lightly.

  • Place the pot in a shaded area for 10 days to allow the cuttings to develop roots and new leaves.

 

2.2. How to Grow Vietnamese Coriander Hydroponically


If you don't have garden soil, you can grow Vietnamese coriander hydroponically. Here's how:

Step 1: Preparation
 

  • Get a plastic container with a lid, such as an old ice cream box. Also, gather some mature, thick cuttings of Vietnamese coriander. It's best to get these from a friend rather than buying them from the market, as market cuttings are often refrigerated and hard to grow.
     

Step 2: Setup
 

  • Punch small holes in the lid of the container, just big enough for the cuttings.

  • Fill the container halfway with water. Insert the cuttings through the holes in the lid and close it.

  • Place the container in a shaded area.

  • Check the water level every few days and add more if necessary. Avoid overfilling to prevent waterlogging and rotting.

  • After about 3 weeks, you can start harvesting the Vietnamese coriander.
     

2.3. How to Grow Vietnamese Coriander from Seeds


Aside from the above methods, you can also grow Vietnamese coriander from seeds. However, this method is less popular due to the long time it takes to harvest and lower survival rates.

If you choose to grow Vietnamese coriander from seeds, follow these steps:
 

Step 1: Seed Preparation

  • Soak the seeds in water at a ratio of "2 parts hot water to 3 parts cold" overnight, then rinse them thoroughly. After that, wrap the seeds in a damp cloth and let them germinate for 24 hours.

Step 2: Soil Preparation and Planting
 

  • Prepare the soil as described for cuttings and sow the seeds.

  • Water lightly to keep the soil moist and place it in a shaded area for 7-10 days.


Step 3: Post-Germination Care
 

  • Once the seeds have germinated and the seedlings are large enough, move them to a sunnier spot.
