Eryngium foetidum L., commonly known as culantro, is a tropical plant that thrives in a warm climate. It is usually found in Central and South American regions. The plant is best grown in a warm environment, with temperatures ranging between 21-29 degrees Celsius.
The cultivation process of culantro begins with the preparation of the soil. The plant prefers well-drained soil with a neutral pH level. Once the soil is ready, the seeds can be sown directly into the soil. Culantro needs a shady spot to germinate effectively. The germination period of the plant can last up to 14 days.
After the germination process, the plant can be transferred to its permanent position. Culantro needs a good amount of space to grow, as it can reach a maximum height of two feet. It is important to keep the soil moist during the early stages of growth to ensure proper growth.
Watering Needs
Culantro needs regular watering to grow properly. It is important to keep the soil moist, especially during the early stages of growth. However, overwatering can be detrimental to the plant, as it can lead to waterlogging.
A good way to monitor the water requirements of the plant is to check the top layer of soil. If the soil feels dry to touch, it is an indication that the plant needs watering. It is advisable to water the plant early in the morning or in the evening when the temperature is low.
Fertilization
Culantro needs fertilization to thrive. The plant needs a balanced fertilizer that contains equal amounts of nitrogen, phosphorus, and potassium. Organic fertilizers such as compost and manure are also suitable for the plant.
Fertilization should be done once every 6-8 weeks during the growing season. It is important not to over-fertilize the plant, as it can lead to excessive growth.
Pruning
Pruning is essential to maintain the shape and size of the plant. Culantro tends to branch out, which can make it look untidy. Pruning can help the plant to grow in a compact and neat manner.
Pruning of culantro should be done once every 2-3 months. It involves cutting off the top growth of the plant. It is important to avoid cutting off too much growth, as it can stunt the growth of the plant.
In conclusion, with proper care and cultivation methods, culantro can be a beautiful and useful addition to an herb garden.

Propagation through cuttings is another method to propagate E. foetidum. Here are the steps to follow:
- Select a healthy stem from the parent plant that has several nodes.
- Cut the stem below a node using a sterilized knife or scissors.
- Remove the leaves from the bottom of the stem.
- Dip the cut end of the stem in rooting hormone to encourage root growth.
- Plant the cutting in a well-draining potting mix and water thoroughly.
- Place the container in a warm, bright location, but out of direct sunlight.
- Keep the soil moist by misting with water regularly.
- The cutting should root within 3-4 weeks.
- Transplant the new plant into a larger container or outdoors once it has established new growth.
Propagation by Root Division
Propagation through root division is a quick way to multiply E. foetidum. Here are the steps to follow:
- Carefully remove the entire plant from the soil.
- Gently separate the root system into smaller sections using a sterilized knife or scissors.
- Plant each section in a well-draining potting mix and water thoroughly.
- Place the container in a warm, bright location, but out of direct sunlight.
- Keep the soil moist by misting with water regularly.
- The new plants should begin to grow within a few weeks.

Pest and Disease Management for Eryngium foetidum L.
Eryngium foetidum L., commonly known as Mexican coriander or Culantro, is a hardy, low-maintenance plant that is resistant to most pests and diseases. However, just like any plant, it is still vulnerable to a few common problems that can affect its growth and yield.
Common Pests Affecting Eryngium foetidum L.
The following are some common pests that might affect your Eryngium foetidum L. plant:
Leafminer
Leafminer larvae tunnel through the leaves of the plant, leaving visible trails that can cause the leaves to become distorted and discoloured. To manage leafminers, remove damaged leaves and spray the plant with neem oil. Neem oil contains a compound called Azadirachtin, which is an effective natural insecticide that disrupts the pests' life cycle.
Whiteflies
Whiteflies are tiny insects that suck the sap from the leaves of the plant. An infestation of whiteflies can cause the leaves of the plant to turn yellow and fall off. To manage whiteflies, spray the plant with a solution of soap and water. The soap smoothers the insects, causing them to die.
Aphids
Aphids are small insects that also feed on the sap of the plant. They are a common pest that can cause significant damage to the plant, such as stunted growth and wilting. To manage aphids, spray the plant with a solution of water and mild soap. Use a cloth to wipe the aphids off the leaves manually.
Common Diseases Affecting Eryngium foetidum L.
The following are some common diseases that might affect your Eryngium foetidum L. plant:
Root Rot
Root rot is a fungal disease that affects the roots of the plant, causing them to rot and decay. The plant may appear wilted, and the leaves may be yellow or brown. To manage root rot, use well-draining soil, avoid overwatering, and remove any infected parts of the plant immediately.
Powdery Mildew
Powdery Mildew is a fungal disease that appears as a white, powdery substance on the leaves and stems of the plant. It can cause the plant to become stunted and reduce yield. To manage powdery mildew, spray the plant with a mixture of 1 tablespoon of baking soda, ½ teaspoon of mild soap and 1 gallon of water. This solution alters the pH of the leaf surface, making it less hospitable to the fungus, and kills the fungus as well.
Leaf Spot
Leaf Spot is a bacterial or fungal disease that affects the leaves and stems of the plant, causing them to develop brown spots. The spots may join and cause the leaves to fall off. To manage leaf spot, remove and destroy infected plant debris, increase air circulation, and avoid overhead watering.
By taking these preventative measures and using natural remedies to manage pests and diseases on your Eryngium foetidum L. plant, you can ensure a healthy and bountiful harvest.
