Hello dear garden friends! Have you ever wondered how you can enjoy the unique taste of fish mint (also known as Vietnamese coriander) right in your kitchen? I’ll show you how you can easily do it at home! Fish mint is not only super delicious but also relatively easy to care for, making it an ideal plant for beginners. Let’s dive into the world of growing fish mint together!
What You Need for Harvesting Fish Mint
Before we get started, here is a list of things you should have ready:
- Fish mint plant: You can either buy a young plant at a garden center or take cuttings from an existing plant.
- Suitable pot: Choose a pot with good drainage. A diameter of at least 15 cm is ideal.
- High-quality potting soil: Fish mint prefers moist but well-draining soil.[1]
- Watering can: For regular watering.
- Pruning shears or sharp scissors: For harvesting the leaves.
- (Optional) Liquid fertilizer: For additional growth.
- (Optional) Spray bottle: For spraying the leaves with water.
The Right Environment for Your Fish Mint
Fish mint loves bright light, but not necessarily direct midday sun. A partially shaded location is perfect.[2] Make sure the plant is protected from strong wind.
- Light: Partial shade to full sun (avoid intense midday sun).[2]
- Temperature: Ideally between 15°C and 25°C.[3]
- Humidity: Fish mint likes high humidity. Regular spraying helps.[2]
Planting Fish Mint: Step by Step
Now let’s get down to it! Here is a detailed guide on how to successfully plant your fish mint:
- Prepare the pot: Fill the pot with potting soil, but leave about 2-3 cm of space to the rim.
- Insert the plant: Carefully remove the fish mint plant from its original container. Loosen the roots slightly if they have grown very densely.
- Planting: Place the plant in the center of the pot and fill the remaining space with soil. Press the soil down lightly.
- Watering: Water the plant thoroughly until water runs out of the drainage holes.
- Choose a location: Place the pot in a suitable location (partially shaded, protected).
Propagating Fish Mint from Cuttings
If you already have a fish mint plant, you can easily propagate it from cuttings. This is a great way to expand your collection or give friends some starts!
- Cut cuttings: Choose healthy, strong shoots. Cut cuttings about 10-15 cm long, directly below a leaf node.[4]
- Remove leaves: Remove the lower leaves of the cutting, leaving only the top leaves.[5]
- Rooting in water: Place the cuttings in a glass of water. Make sure the lower leaf nodes are in the water.[5]
- Wait for root formation: Place the glass in a bright place, but not in direct sun. Change the water every few days. Roots should form after about 1-2 weeks.[6]
- Planting: Once the roots are about 2-3 cm long, you can plant the cuttings in pots with potting soil.[6]
Caring for Fish Mint: Tips and Tricks
Proper care is crucial for a bountiful harvest. Here are my best tips:
- Watering: Fish mint likes it moist, but not wet. Water regularly, especially on hot days. Check the soil before watering – it should feel slightly moist.
- Fertilizing: Fertilize the plant every 2-4 weeks with a liquid fertilizer for herbs.
- Pruning: Regular pruning encourages growth and prevents the plant from becoming too long and sparse.
- Overwintering: Fish mint is not hardy. In the fall, move the plant to a bright, cool place (e.g., a greenhouse or a bright basement). Water less, but do not let the soil dry out completely.[3]
- Pests: Watch out for pests like aphids or spider mites. If infested, you can treat the plant with a mild insecticide or a soap solution.
Harvesting Fish Mint: The Right Time and Technique
Finally! The moment we’ve all been waiting for: the harvest!
- When to harvest? You can harvest the leaves as soon as the plant has grown sufficiently. It is best to harvest in the morning when the essential oils are most concentrated.[7]
- How to harvest? Cut the leaves with pruning shears or sharp scissors. You can harvest individual leaves or entire shoots. Be careful not to remove too many leaves at once, so the plant can continue to grow.
- Storage: Fresh fish mint leaves are best used immediately. However, you can also store them in the refrigerator for a few days. Wrap the leaves in a damp paper towel and place them in a plastic bag.
Fish Mint in the Kitchen: Versatile Uses
Fish mint is a real all-rounder in the kitchen! Its unique flavor goes wonderfully with many dishes.
- Vietnamese cuisine: Fish mint is a must in many Vietnamese dishes such as summer rolls (Gỏi cuốn), Pho, and salads.[8]
- Salads: Adds a fresh, exotic touch to your salads.
- Soups: Add it to soups just before serving.
- Meat and fish dishes: Pairs well with grilled meat or fish.
- Drinks: Use it in cocktails or as a garnish for lemonades.
Common Problems and Solutions
Problems can also arise when growing fish mint. Here are some common problems and how to solve them:
- Yellow leaves: Can be caused by overwatering, nutrient deficiency, or too little light. Adjust watering, fertilize the plant, and move it to a brighter location.
- Brown leaves: Can be caused by too much sun or drought. Protect the plant from the midday sun and water regularly.
- Pests: If infested, treat the plant with a suitable insecticide or a soap solution.
Additional Tips for a Successful Fish Mint Harvest
Here are a few more tips that will help you optimize your fish mint harvest:
- Regular repotting: Repot the plant into a larger pot every 1-2 years to give it more space to grow.
- Mulching: A thin layer of mulch (e.g., bark mulch or straw) helps to retain moisture in the soil and suppress weeds.[9]
- Observation: Pay attention to changes in the plant’s appearance. The sooner you identify problems, the easier it is to fix them.
I hope this guide has helped you to grow and harvest your own fish mint at home. With a little care and attention, you can soon look forward to a bountiful harvest and enjoy the unique taste of this wonderful plant.

Frequently Asked Questions (FAQ)
1. Is fish mint difficult to grow?
No, fish mint is generally considered an easy herb to grow, especially for beginners. It’s relatively low-maintenance and can tolerate a wide range of conditions. However, it does have a few specific needs, such as plenty of sunlight and consistent moisture. As long as you provide these, you should have no problem growing your own fish mint. The most important thing to remember is that it can be invasive, so containing it is key.
2. What kind of soil is best for growing fish mint?
Fish mint prefers well-draining soil that is rich in organic matter. A good potting mix for containers is a blend of peat moss, perlite, and vermiculite. You can also amend your garden soil with compost or other organic materials to improve its drainage and fertility. The ideal pH for fish mint is slightly acidic to neutral, around 6.0 to 7.0.
3. How much sunlight does fish mint need?
Fish mint thrives in full sun, which means at least six hours of direct sunlight per day. However, it can also tolerate partial shade, especially in hot climates. If you’re growing fish mint indoors, place it near a sunny window or provide supplemental lighting. Insufficient sunlight can lead to leggy growth and reduced flavor.
4. How often should I water fish mint?
Fish mint prefers consistently moist soil, but it doesn’t like to be waterlogged. Water your plant whenever the top inch of soil feels dry to the touch. During hot, dry weather, you may need to water it more frequently. Be sure to provide good drainage to prevent root rot. A self-watering container can be helpful in maintaining consistent moisture levels.
5. How do I harvest fish mint?
You can harvest fish mint leaves as needed throughout the growing season. Simply snip off the leaves with scissors or your fingers. Avoid removing more than one-third of the plant at a time, as this can stress it. Regular harvesting will encourage bushier growth. The best time to harvest is in the morning, after the dew has dried.
6. Is fish mint invasive?
Yes, fish mint is known to be invasive, especially when grown directly in the ground. It spreads rapidly through its underground rhizomes, which can quickly take over a garden bed. To prevent it from spreading, it’s best to grow fish mint in a container or raised bed. You can also install a barrier around the plant to contain its roots.
7. Can I grow fish mint indoors?
Yes, you can grow fish mint indoors, as long as you provide it with enough sunlight and moisture. Place the plant near a sunny window or provide supplemental lighting. Be sure to use a well-draining potting mix and water regularly. Indoor-grown fish mint may not be as vigorous as outdoor-grown plants, but it can still provide you with a steady supply of fresh leaves.
8. What are some common problems with growing fish mint?
Some common problems with growing fish mint include root rot, pests, and diseases. Root rot can occur if the soil is too wet or poorly drained. Pests such as aphids and spider mites can also attack fish mint. Diseases such as powdery mildew can also be a problem, especially in humid conditions. To prevent these problems, provide good drainage, monitor your plants regularly for pests and diseases, and take appropriate action if necessary.
9. How do I propagate fish mint?
Fish mint is easy to propagate from cuttings. Simply take a 4-6 inch cutting from a healthy stem and remove the lower leaves. Dip the cut end in rooting hormone and plant it in a pot filled with moist potting mix. Keep the soil moist and place the pot in a warm, sunny location. The cutting should root within a few weeks. You can also propagate fish mint by dividing the rhizomes.
10. What are some culinary uses for fish mint?
Fish mint is a versatile herb that can be used in a variety of dishes. It’s commonly used in Southeast Asian cuisine, particularly in Vietnamese, Thai, and Cambodian dishes. It can be added to salads, soups, stir-fries, and spring rolls. It can also be used to make tea or infused into vinegar or oil. The unique, slightly fishy flavor of fish mint adds a distinctive touch to any dish.
