For a cooking enthusiast like me, cilantro has been a crucial ingredient for most of my dishes. The last touch of garnishing with cilantro just makes it even more presentable and aromatic. 

I prefer to use my homegrown ingredients for cooking, and compromising on the freshness of cilantro makes its use worthless. Learning how to grow cilantro made me learn and value this natural herb even more. 

Whether it is fresh leaves or dried seeds, growing cilantro is incredibly easy, and it can be grown all year long with the right care.  

Explore everything about this ancient herb and how you can make the best out of it. 

What is Cilantro? Introduction, Nutritional Value and  Taxonomic Details

Cilantro is an ancient herb known for its citrusy flavour, used for garnishing food items like curries and salsas. Being a member of the Apiaceae family, the leaves and stems of the Coriandrum sativum plant are referred to as cilantro, and the dried seeds as coriander. 

However, in the Asian part of the world, both the leaves and seeds are referred to as coriander. Both these terms are used interchangeably. One of the major producers of cilantro includes India, Mexico, China, South America, and Central America.

What are the Best Growing Conditions for Cilantro?

Cilantro thrives in cool temperatures, but complete shade is not appropriate. 

While growing the cilantro plant along with maintaining the balance between shade and sunlight, these are the things that I keep in mind, and you should too:

  1. When to Plant Cilantro: 

    Cilantro is best grown in cool weather. So, early spring or late fall is the perfect time to plant the seeds. 

  1. Soil Requirements

    It grows in loose, loamy, well-draining soil with an acidic pH(6.2 – 6.8). 

    The roots of cilantro have a high risk of getting damaged in soggy, waterlogged soil. 

    Hence, a well-draining soil is a must for healthy growth. 

  1. Sunlight 

    The cilantro plant should receive 6 hours of direct sunlight, but make sure that it is not exposed to direct afternoon sunlight, as this causes the plant to bolt too early. 

    Either place it in partial shade or in a container that could be moved indoors. 

Personal takeaway

I grew cilantro in pots so that I could move them indoors whenever required.

  1. Temperature

    Cilantro prefers a temperature between 60-70 degrees Fahrenheit. Hot weather conditions can cause it to bolt easily. 

    Although they grow best in cool temperatures, they cannot resist frost. 

    Keep them covered or move them indoors in an extremely cold climate.  

  1. Water Requirements 

    Cilantro grows best in well-draining, moist soil. Watering it 1 inch per week is perfect for its growth. 

    After the Cilantro seedlings have appeared, they do not require frequent watering, but make sure the soil is moist at all times and look out for waterlogging. 

How do I Plant Cilantro at Home? 

Planting cilantro seeds is the best and most common way to grow cilantro. It has delicate leaves and roots that could get damaged while planting through plugs. 

Here is how to grow cilantro seeds for the best results: 

  1. Choose the site that has loose and well-draining soil, and sow the cilantro seeds.
  1. Sow them at least ¼ inch deep and 6 inches apart to ensure good airflow. 
  1. Make sure they are not planted near a tall tree that blocks the sun’s rays. 
  1. Water it enough to keep the soil moist, avoiding waterlogging that could lead to root rot. 

Personal Tip 

I used to thin my cilantro plant when the seedlings grew up to 2 inches tall. This would give them better access to sunlight and water. 

How to Harvest Cilantro After Growing? 

My favourite part about growing cilantro is that it takes only 3-4 weeks to grow completely for use. In about a month, it grows up to 6 inches tall and is ready to harvest. 

Steps to harvest Cilantro: 

  1. Identify the leaves that look green and healthy; they are usually the most flavourful ones. 
  1. Using pruning shears or scissors, snip out ⅓ of the stems towards the base of the plant. 
  1. Leave out the smaller leaves and avoid cutting more than ⅓ of the individual branches towards the base, allowing the plant to regrow.  
  1. Cilantro can ideally be harvested every week until fresh growth. 

How to Dry the Cilantro Seeds? 

Should I let coriander seeds dry on the plant Reddit query

Yes, letting the seeds dry out on the cilantro plants is the way to obtain the coriander seeds. 

Here is how you identify and pick dry seeds from the plant: 

  1. During extremely hot weather, the plant will bolt. That means it will produce white flowers that will be followed by small seeds.

  1. Pick the seed heads and store them in a ventilated space to finish drying.

  2. Store them in an air-tight container. Make sure they are completely dry to prevent mould.

Drying cilantro seeds is the best way to preserve and use them for a longer time. The leaves are fresh, but they dry out quickly. However, dry cilantro seeds can be used as a spice in cooking, enhancing the taste and aroma of the food. 

How Should I Propagate Cilantro? 

Cilantro is best propagated using seeds, as it yields better results compared to leaves. 

I propagate cilantro during early fall for a continuous supply throughout the harsh winter months. 

Propagating them is hassle-free; just follow the following steps: 

  1. Split the whole seeds in half or soak them in water overnight to help them germinate. 
  1. Sow the seeds ½ inch deep in a moist, well-draining soil. 
  1. Plant them 4 inches apart to avoid overcrowding. 
  1. Water it gently, keep the soil moist, and in a few weeks, the cilantro seedlings will appear.
