Cilantro is a flavorful herb that’s a staple in many kitchens worldwide. Its fresh, tangy leaves add a unique taste to salads, soups, and sauces. One of the best things about cilantro is that you can easily grow it indoors, even if you don’t have a garden. Growing cilantro indoors from seed is simple, rewarding, and provides a fresh supply of this herb year-round.

In this guide, we’ll walk you through the step-by-step process of growing cilantro indoors. We will also cover the differences between cilantro and coriander, their culinary uses, and the health benefits they provide.

Cilantro vs Coriander: What’s the Difference?

Cilantro and coriander often cause confusion because they come from the same plant. However, these terms are used differently depending on where you are in the world.

  • Cilantro: In the United States and many other parts of the world, “cilantro” refers to the fresh leaves of the plant (Coriandrum sativum). These leaves are typically used as an herb.
  • Coriander: The term “coriander” generally refers to the dried seeds of the same plant. Coriander seeds are used as a spice and have a slightly different flavor compared to the fresh leaves.

In other countries, particularly the UK and India, “coriander” refers to both the leaves and the seeds. This can create confusion, so it’s important to clarify which part of the plant you’re referring to when cooking or shopping.

Step-by-Step Guide to Growing Cilantro Indoors from Seed

1. Choose the Right Pot and Soil

To grow cilantro indoors, start by selecting a container with good drainage. A pot that is at least 8-10 inches deep will give cilantro roots enough space to grow. Choose a well-draining, organic potting mix for the best results. Cilantro prefers slightly moist soil, but it should never be soggy.

2. Select Your Cilantro Seeds

Cilantro seeds, also called coriander seeds, are widely available at garden centers and online. Look for organic, untreated seeds for the best growth. Before planting, you can lightly crush the seeds to help them germinate faster, but this is not necessary.

3. Plant the Seeds

Sprinkle the cilantro seeds evenly over the surface of the soil, then cover them lightly with about 1/4 inch of soil. Cilantro seeds need darkness to germinate, so covering them well is essential. Water gently, keeping the soil evenly moist but not waterlogged.

4. Provide the Right Growing Conditions

Cilantro thrives in cool temperatures, so place your pot in a spot that gets plenty of sunlight but stays between 60-70°F (15-21°C). A sunny windowsill is an ideal location for cilantro to grow. If you don’t have enough natural light, consider using a grow light for 6-8 hours a day.

5. Water and Care for Your Cilantro

Water your cilantro regularly, ensuring that the soil stays moist but not too wet. Cilantro doesn’t like being too dry, so check the soil daily. Every few weeks, you can fertilize your plants with a balanced, organic fertilizer to encourage healthy growth.

6. Harvesting Cilantro

Cilantro is ready to harvest in about 3-4 weeks. You can start cutting the outer leaves once the plant reaches about 6 inches tall. Be sure to leave the central stems intact so the plant can continue growing. Regular harvesting encourages more leaf production, so don’t hesitate to snip away as needed.

Cilantro vs. Coriander: Different Uses in Cooking

Both cilantro leaves and coriander seeds are popular ingredients in global cuisine, but they have distinct flavors and uses in cooking.

  • Cilantro: The fresh leaves are commonly used in Mexican, Indian, and Southeast Asian dishes. They add a bright, citrusy note to foods like salsa, guacamole, curry, and pho. Fresh cilantro is best added at the end of cooking to preserve its flavor.
  • Coriander Seeds: These dried seeds are often ground into a powder and used as a spice in cooking. Coriander seeds have a warm, nutty flavor with a hint of citrus. They are used in spice blends like garam masala and curry powder, as well as in baking and pickling.

In essence, cilantro (the leaves) adds freshness to dishes, while coriander seeds provide a deeper, earthy flavor.

The Best Substitutes for Coriander Seeds

If you run out of coriander seeds, there are several substitutes that can mimic their flavor in cooking:

  1. Cumin Seeds: These have a warm, earthy flavor similar to coriander, though slightly more intense. Use cumin in equal amounts to replace coriander seeds.
  2. Caraway Seeds: With a slightly peppery and citrusy taste, caraway seeds can work well as a substitute for coriander in bread and stews.
  3. Fennel Seeds: Fennel offers a sweeter, more anise-like flavor but can still be used as a coriander seed substitute in some recipes.
  4. Garam Masala: This spice blend often includes coriander and can be a convenient substitute in Indian dishes.
  5. Dried Cilantro Leaves: If you don’t have coriander seeds, dried cilantro leaves can sometimes be used in small amounts to add a similar fresh flavor.

Possible Health Benefits of Cilantro and Coriander

Cilantro and coriander both offer a variety of potential health benefits, making them a great addition to your diet.

  • Rich in Antioxidants: Both cilantro leaves and coriander seeds are packed with antioxidants, which help to protect cells from damage caused by free radicals.
  • Anti-Inflammatory Properties: Some studies suggest that cilantro and coriander may have anti-inflammatory effects, potentially helping to reduce the risk of chronic diseases like heart disease and arthritis .
  • Digestive Health: Coriander seeds, in particular, have been traditionally used to aid digestion and relieve symptoms of bloating and gas.
  • Detoxifying Agent: Cilantro has been shown to help detoxify heavy metals from the body, including lead and mercury .

Common Challenges When Growing Cilantro Indoors

Growing cilantro indoors from seed is generally straightforward, but you might face a few challenges along the way.

  • Bolting: Cilantro has a tendency to bolt, or go to seed, especially in warm conditions. When cilantro bolts, the plant stops producing leaves and focuses on making seeds instead. To prevent this, keep the plant in cool conditions and harvest the leaves regularly.
  • Pests: Cilantro is relatively pest-resistant, but indoor plants can occasionally attract aphids or whiteflies. Use natural insecticidal soap to keep pests at bay.
  • Overwatering: Cilantro likes moist soil, but overwatering can lead to root rot. Make sure your pot has proper drainage and water only when the top inch of soil feels dry.
