Culantro (Eryngium foetidum) is a flavorful herb used in many Caribbean, Asian, and Latin American cuisines. It’s often called “long coriander” because it has a similar taste and aroma to cilantro but with longer, spikier leaves.

If you’re growing culantro at home and notice that your plant is dying, it can be frustrating. Here are some possible reasons why your culantro plant is struggling and what you can do to save it.

Lack of Water

Like all plants, culantro needs water to survive. If the soil around your culantro plant is dry or if you’re not watering it enough, it may be causing the plant to wilt and eventually die. Make sure to water your culantro regularly and keep the soil moist, but not waterlogged.

Poor Soil Quality

Culantro prefers well-draining soil that’s rich in organic matter. If your soil is too compacted or lacks nutrients, it could be causing your culantro plant to suffer. Consider adding compost or other organic matter to the soil to improve its quality.

Pests or Diseases

Culantro is susceptible to a variety of pests and diseases, including aphids, spider mites, and powdery mildew. If you notice any signs of infestation or disease on your culantro plant, take action immediately. You can use insecticidal soap or neem oil to control pests, and fungicides may help with diseases.

Temperature Extremes

Culantro prefers warm temperatures between 70-85°F (21-29°C). If the temperature drops below 60°F (15°C) or rises above 90°F (32°C), it can stress the plant and cause it to die. Make sure to keep your culantro plant in a location with consistent temperatures and protection from extreme weather conditions.


While culantro needs nutrients to grow, too much fertilizer can harm the plant. If you notice that your culantro leaves are turning yellow or brown, it could be a sign of over-fertilization. Make sure to follow the instructions on your fertilizer and avoid applying too much.


Can I grow culantro indoors?

Yes, culantro can be grown indoors as long as it’s in a location with bright, indirect sunlight and consistent temperatures.

How often should I water my culantro plant?

Culantro should be watered regularly, typically once or twice a week depending on the weather and soil conditions.

Can I harvest culantro before it flowers?

Yes, you can harvest culantro leaves before the plant flowers. Simply cut off the top leaves with scissors or pruning shears.

How do I store harvested culantro?

Culantro can be stored in the refrigerator in a plastic bag or container for up to a week. You can also freeze chopped culantro in ice cube trays for later use.

In conclusion, there are several reasons why your culantro plant may be dying, but with proper care and attention, you can save it. Make sure to water your plant regularly, provide high-quality soil, protect it from pests and diseases, and maintain consistent temperatures. With these measures in place, you can enjoy fresh, flavorful culantro in your cooking for months to come.
