Propagating Cilantro Indoors

How to Grow Cilantro Indoors 2

Methods to propagate cilantro indoors:

Seed Germination: This is the easiest and most common way to propagate cilantro indoors.

  1. Select Quality Seeds: Begin with high-quality cilantro seeds, preferably organic, as they have a better germination rate.
  2. Container: Choose a shallow, wide container or a seed tray with drainage holes. Fill it with a well-draining potting mix.
  3. Sow the Seeds: Sprinkle the cilantro seeds evenly over the soil surface. Press them lightly into the soil so they make good contact.
  4. Moisture: Water the soil gently to ensure it’s evenly moist but not waterlogged.
  5. Cover and Encourage Germination: Place a plastic wrap or a clear plastic lid over the container to create a mini greenhouse effect. This helps maintain humidity and warmth, promoting germination.
  6. Warmth and Light: Put the container in a warm, well-lit area with indirect sunlight or under grow lights. Cilantro prefers temperatures between 60-75°F (15-24°C).
  7. Germination: Cilantro seeds typically germinate in about 7-14 days. Once you see small seedlings, remove the plastic cover.
  8. Thinning: If multiple seedlings emerge in one spot, thin them out, leaving the healthiest-looking one.
  9. Care: Keep the soil consistently moist but not waterlogged. Ensure the seedlings receive adequate light, ideally around 6-8 hours of indirect sunlight or under grow lights.
  10. Transplant: When the seedlings have grown a few inches tall and have a couple of true leaves, you can transplant them into individual pots or your desired indoor herb garden.

Best Pot Size for Growing Cilantro Indoors

For indoor cilantro, choose pots that are 6-8 inches (15-20 cm) in diameter and 6-8 inches deep. Use lightweight plastic or clay pots with drainage holes to ensure proper moisture control. Well-draining potting mix and containers with saucers to catch excess water will help maintain cilantro’s health and vigor.

Requirements for Growing Cilantro Indoors

How to Grow Cilantro Indoors 7


Cilantro grown indoors needs at least 6-8 hours of direct and indirect sunlight daily, preferably near a south or west-facing window that receives some sun is best.

Rotation: Rotate the pot occasionally for even growth and light exposure.

Note: Cilantro thrives in sunny conditions, but excessive heat can cause it to bolt (go to seed) prematurely. If you’re growing it on a balcony or patio in a hot region (USDA Zone 10 and 11 and other similar climates), provide shade in the afternoon to prevent bolting.


Creating a homemade potting mix tailored for cilantro can promote larger leaves and better flavor. Below are the key components for an optimal potting mix and their respective benefits.

1. Coconut Coir or Peat Moss (40%)

  • Role: Retains moisture and provides aeration.
  • Benefit: Helps to keep the soil moist but not waterlogged, aiding in nutrient absorption.

2. Perlite or Vermiculite (30%)

  • Role: Aids in drainage.
  • Benefit: Prevents root rot by ensuring that excess water drains away from the root zone.

3. Compost or Well Rotted Manure (20%)

  • Role: Provides essential nutrients.
  • Benefit: Adds organic matter and essential nutrients to the soil, enhancing leaf size and flavor.

4. Worm Castings (10%)

  • Role: Adds beneficial microbes and nutrients.
  • Benefit: Stimulates root growth and improves soil structure, contributing to better nutrient uptake.

Water cilantro when the top inch of soil feels dry to the touch. Typically, this means watering every few days but adjust based on temperature and humidity levels in your home.

Method: Watering at the base is preferable to avoid wetting the foliage, which can lead to mold.

Temperature and Humidity

Cilantro indoors prefers temperatures above 60°F (15°C), which you can easily provide. Maintain a moderate indoor humidity level of around 40-50% to prevent drying out or wilting. Adequate ventilation helps maintain these conditions and keeps cilantro healthy and thriving.

Cilantro Care Indoors


To boost the production of leaves, use a balanced liquid fertilizer diluted to 1/2 of its strength once in 2-3 weeks.

Homemade fertilizers can be an effective and eco-friendly way to provide essential nutrients to your indoor cilantro. Below are some options, along with guidelines on how and when to apply them.

Coffee Grounds

  1. Dosage: 1 tablespoon per pot.
  2. How to Use: Sprinkle the used coffee grounds on top of the soil.
  3. When to Use: Once a month.
  4. Benefit: Adds nitrogen to the soil, which promotes leafy growth.

Eggshell Tea

  1. Dosage: One eggshell per quart of water.
  2. How to Use: Boil crushed eggshells in water, let it cool, and then water the cilantro.
  3. When to Use: Every 2-3 weeks.
  4. Benefit: Provides calcium, which helps in the cell wall structure.

Banana Peel Fertilizer

  1. Dosage: One banana peel per pot.
  2. How to Use: Bury small pieces of a banana peel 1-2 inches below the soil surface or sprinkle the powder made of it.
  3. When to Use: Once a month.
  4. Benefit: Adds potassium, which helps in growth.

Compost Tea

  1. Dosage: 1 part compost to 5 parts water.
  2. How to Use: Steep compost in water for 24-48 hours, strain, and then use the liquid to water the cilantro.
  3. When to Use: Every 2-3 weeks.

Periodically check your cilantro plants for flower development. If you spot flowers, practice deadheading by removing them. This encourages leaf growth.

Alternatively, allow the flowers to stay if you wish to collect seeds. Deadheading helps prevent premature bolting and ensures a longer harvest of fresh cilantro leaves.


While growing cilantro indoors, you don’t need to worry much about the pests, as your home is a more controlled environment. However, it’s good to know the enemy:

  1. Aphids
  • Identification: Small, soft-bodied insects clustering under leaves.

Harvesting Cilantro

Timing for Harvest

  • Maturity Level: Harvest cilantro when it has at least 6-8 adult leaves.
  • Early Morning: Harvest in the early morning when the leaves have the highest water content, ensuring better flavor and longer shelf-life.

Methods of Harvesting

1. Leaf Harvesting Method

  • Technique: Using sharp scissors, snip off individual leaves, leaving at least two-thirds of the plant intact.
  • When to Use: Ideal for small, occasional harvests.

2. Cut-and-Come-Again Method

  • Technique: Cut the entire plant about 2 inches above soil level, allowing the lower leaves and new shoots to continue growing.
  • When to Use: Recommended when you need a larger quantity of cilantro.

3. Stem Harvesting Method

  • Technique: Cut off the stems near soil level, ensuring you don’t remove more than one-third of the plant.
  • When to Use: Useful when you also need the stems for cooking, but make sure to leave enough for the plant to recover.

Tips for Harvesting Without Damaging the Plant

  • Sharp Tools: Always use sharp scissors or pruners to make clean cuts, reducing stress on the plant.
  • Harvest Outer Leaves: Harvest the older, outer leaves first, leaving the young inner leaves to continue growing.
  • Limit Quantity: Don’t harvest more than one-third of the plant at one time to allow for sufficient regrowth.
  • Monitor for Bolting: Cilantro can quickly go to seed (bolting), especially in warm conditions. Harvest regularly to delay bolting and extend the harvesting period.

Post-Harvest Handling

  • Immediate Use: If you intend to use the cilantro immediately, simply wash it under cold water.
  • Storage: To store, wrap the harvested leaves in a damp paper towel and place them in a zip-lock bag in the refrigerator. You can also freeze the leaves for later use.
