Fish Mint can be grown from seeds or cuttings. However, many people prefer the cutting method because it is easy to implement, highly effective, and allows for the use of cuttings after purchasing the herb. To grow this herb, follow these three steps:

How to Grow Fish Mint (Houttuynia cordata)


  • Remove the leaves and young tips from the Fish Mint . Keep the sturdy stems for planting.
  • Before planting, use a knife to cut just above the first node (about 3 mm from the node) because the roots will grow from this first node. Additionally, you only need to leave 2-3 nodes on the stem; if it is too long, trim it down.
  • Prepare some construction sand and add water to moisten it (using this type of sand increases the success rate of rooting). Place the moistened sand into a pot for rooting, and spray water evenly to level the sand surface.
  • Insert the prepared Fish Mint  stem into the sand at a depth of 1.5 to 2 cm to ensure the stem stands upright. After that, mist it again to help the sand hold the stem firmly.

  • After 1 week of rooting, choose the cuttings that have developed roots and prepare to plant them.
  • Dig a small hole about 1.5 to 2 cm deep, place the rooted cutting in, and cover it with soil. (After planting, mist the entire plant to keep it moist.)
  • Water once a day (in the morning and evening). If the weather is very sunny, water twice a day. If it rains, there’s no need to water.
