How to Plant Cilantro Seeds
So, you’ve got your seeds—now what? Let’s talk about planting cilantro seeds and getting them to sprout into those lovely, fragrant plants.
How Deep to Plant Cilantro Seeds
When it comes to planting cilantro seeds, depth is key. Plant the seeds about a quarter-inch deep in well-draining soil. If you plant them too deep, they might struggle to break through the soil; too shallow, and they could dry out before they even start.
Soil and Location
Cilantro isn’t too picky about soil, but it thrives best in well-draining soil rich in organic matter. Whether you're planting cilantro seeds in pots or directly in the ground, choose a spot with plenty of sunlight.
Cilantro loves the sun, but if you live in a particularly hot climate, a little afternoon shade will keep it from bolting too quickly.
Growing Cilantro from Seed in Containers
If you’re limited on space, or just love the idea of a portable herb garden, growing cilantro from seed in containers is a fantastic option. Choose a pot that’s at least 8 inches deep to allow for root growth. Remember, cilantro has a taproot, so the deeper the pot, the better.

Growing Cilantro from Seed Indoors vs. Outdoors
Whether you choose to grow cilantro indoors or outdoors depends largely on your climate and available space. Both methods have their perks, so let’s break them down.
Growing Cilantro from Seed Indoors
Growing cilantro from seed indoors is perfect for those who live in cooler climates or don’t have access to a garden. It also allows you to have fresh herbs year-round, no matter the weather.
Place your pots near a sunny window, and make sure the soil stays moist but not soggy.
Growing Cilantro from Seed Outdoors
If you have the space, growing cilantro from seed outdoors allows the plants to grow bigger and more robust.
Cilantro thrives in cooler temperatures, so early spring or fall is the ideal time for planting cilantro seeds outdoors. Just make sure to plant your cilantro in a spot that gets full sun.
Growing Cilantro from Seed in Pots Outdoors
Don’t have a garden bed? No problem! Growing cilantro from seed in pots outdoors gives you the flexibility to move your plants around to catch the best light. It’s also a great way to avoid overcrowding and keep pests at bay.
Growing Cilantro from Seed in Water: Is It Possible?
Believe it or not, you can even grow cilantro from seed in water. This method isn’t as common, but it’s an interesting option if you’re tight on space or want to try something new.
Simply place cilantro seeds on a damp paper towel, roll it up, and place it in a glass with a small amount of water at the bottom. Keep the towel damp, and within a few days, you should see tiny sprouts.

How to Grow Cilantro from Cuttings
While cilantro is typically grown from seed, you can also propagate it from cuttings. This method isn’t as common but can be a fun way to multiply your plants.
Step-by-Step Guide:
- Choose Healthy Cilantro Stems: Select a healthy, non-flowering cilantro stem about 3-4 inches long. Make sure the stem is green and free of any disease or damage.
- Cut Just Below a Leaf Node: Use a clean, sharp knife or scissors to cut the stem just below a leaf node (the point where the leaves grow out of the stem).
- Place the Cutting in Water: Place the cut end of the cilantro stem in a glass of water, ensuring that the leaf node is submerged. Place the glass in a bright spot but out of direct sunlight.
- Wait for Roots to Form: Within a few days, you should see roots starting to develop from the submerged leaf node. Once the roots are about an inch long, the cutting is ready to be transplanted.
- Transplant into Soil: Carefully transplant the rooted cutting into a pot or garden bed with well-draining soil. Water the cutting well and keep the soil moist as it establishes itself.
- Care for Your New Plant: Treat your newly planted cilantro cutting just like you would a seed-grown plant—give it plenty of sunlight and water regularly.
The Best Time to Grow Cilantro
Timing is everything when it comes to growing cilantro, especially if you want to avoid bolting and get the most flavorful leaves.
Optimal Planting Times:
- Early Spring: The best time to plant cilantro seeds is in early spring when temperatures are cool. Cilantro thrives in temperatures between 50°F and 85°F (10°C to 29°C).
- Fall: If you live in a region with mild winters, fall is also a great time to plant cilantro. The cooler temperatures will extend the growing season, and you can enjoy fresh cilantro well into the winter.
Growing Cilantro Indoors Year-Round:
If you want to grow cilantro year-round, consider growing it indoors. Plant your cilantro seeds in pots and place them on a sunny windowsill where they’ll get plenty of light. This way, you can have fresh cilantro even in the middle of winter.
Mistakes to Avoid When Growing Cilantro
Growing cilantro might seem straightforward, but there are a few common pitfalls that can trip up even experienced gardeners. Avoid these mistakes to ensure a bountiful cilantro harvest.
Planting Cilantro in Hot Weather
Cilantro is a cool-weather plant, and planting it in hot weather is a surefire way to make it bolt. To avoid this, plant your cilantro in early spring or fall when the temperatures are cooler. If you’re growing cilantro in the summer, provide some afternoon shade to keep it cool.
Overwatering or Underwatering
Cilantro likes consistently moist soil, but it doesn’t like to sit in water. Overwatering can lead to root rot, while underwatering can stress the plant and cause it to bolt. Make sure the soil is well-draining and water your cilantro regularly, especially during dry spells.
Not Harvesting Often Enough
Cilantro is a fast-growing plant, and if you don’t harvest regularly, it will quickly go to seed. To keep your cilantro producing fresh leaves, harvest frequently and remove any flower buds that start to form.
Crowding the Plants
Cilantro plants need space to grow. If they’re planted too close together, they can become overcrowded, leading to poor air circulation and increased risk of disease. When planting cilantro seeds, space them about 6 inches apart to allow for proper growth.
Ignoring Soil Quality
Cilantro thrives in well-draining, nutrient-rich soil. If the soil is poor or compacted, your plants may struggle to grow. Before planting cilantro, amend your garden bed or potting soil with compost or organic matter to ensure it’s rich in nutrients.
Caring for Your Cilantro Plants
Once your cilantro seeds have sprouted, the real fun begins. Caring for your cilantro plants is straightforward, but there are a few things to keep in mind.
Watering
Cilantro likes its soil moist but not waterlogged. Water your plants regularly, especially during dry spells, but be careful not to overwater, as cilantro can be prone to root rot.

Feeding
Cilantro doesn’t require heavy feeding, but a light application of compost or a balanced organic fertilizer will give your plants a nice boost, especially if you’re growing cilantro in pots or containers.
Pruning and Harvesting
To keep your cilantro plants healthy and productive, pinch off any flowers that start to form. This will prevent the plant from bolting, which can cause the leaves to turn bitter.
When it comes time to harvest, snip the outer leaves first, allowing the inner leaves to continue growing. This way, you’ll have a continuous supply of fresh cilantro for weeks.
Is Cilantro and Coriander the Same Plant?
If you’ve ever been confused by the terms “cilantro” and “coriander,” you’re not alone. Many people wonder if they’re the same plant or if they’re two entirely different species.
Yes, cilantro and coriander come from the same plant, Coriandrum sativum. The difference lies in how the plant is used in cooking and what part of the plant is being referred to.
- Cilantro refers to the fresh leaves and stems of the plant. In the United States and Canada, when people say “cilantro,” they are usually talking about the leafy green part used in various dishes like salsas, salads, and garnishes.
- Coriander refers to the seeds of the plant. These seeds are often dried and ground into a spice, commonly used in Indian, Middle Eastern, and Asian cuisine.
In other parts of the world, such as the UK and Australia, “coriander” can refer to both the leaves and the seeds, which can add to the confusion. But rest assured, whether you’re growing cilantro for its leaves or harvesting coriander seeds, you’re dealing with the same plant.
How to Tell When Cilantro Is Starting to Bolt
Bolting is the term used when a plant starts to flower and go to seed prematurely, often due to environmental stress such as hot temperatures. When cilantro bolts, the leaves can become bitter, and the plant's focus shifts from leaf production to seed production.
Signs That Your Cilantro Is Bolting:
- Tall, Slender Stems: As cilantro starts to bolt, you’ll notice that the stems become taller and thinner, stretching upward.
- Flower Buds Forming: Small white or pale pink flower buds will begin to appear at the top of the stems.
- Change in Leaf Shape: The leaves near the base of the plant may remain broad and flat, but as the plant bolts, the upper leaves will become more feathery and finely divided.
- Bitter Taste: If you taste the leaves and notice a sharp, bitter flavor, your cilantro is likely bolting.
How to Prevent Bolting:
- Plant in Cooler Temperatures: Cilantro is a cool-weather herb, so try planting in early spring or fall when temperatures are lower.
- Provide Shade: If you’re growing cilantro in the summer, provide partial shade during the hottest part of the day.
- Water Consistently: Keep the soil moist to prevent the plant from becoming stressed and bolting prematurely.
Common Cilantro Problems
No plant is completely trouble-free, and cilantro is no exception. Here’s how to handle some of the most common issues you might encounter.
Bolting
Bolting is the biggest challenge when growing cilantro. This occurs when the plant starts to flower and go to seed, usually in response to hot weather.
To prevent bolting, plant your cilantro early in the spring or in the fall when temperatures are cooler. If your cilantro does bolt, don’t worry—you can still harvest the seeds to use as coriander or plant again.
Pests
Cilantro is relatively pest-resistant, but aphids and whiteflies can sometimes be an issue. A strong spray of water or a natural insecticidal soap can help keep these pests at bay.
Yellowing Leaves
If your cilantro leaves start to yellow, it could be a sign of overwatering, poor drainage, or a lack of nutrients. Adjust your watering schedule and consider adding some organic compost to the soil.
Additional Tips for Growing Cilantro
While we've covered the essentials, here are a few extra tips to help you get the most out of your cilantro plants.
Tip 1: Companion Planting
Cilantro is a great companion plant for a variety of vegetables and herbs. It can help deter pests when planted alongside tomatoes, peppers, and spinach. Additionally, cilantro attracts beneficial insects like ladybugs and hoverflies, which can help control aphids and other garden pests.

Tip 2: Successive Planting
To ensure a steady supply of fresh cilantro throughout the growing season, practice successive planting. Sow new seeds every 2 to 3 weeks, especially during the cooler months, to keep a continuous crop going.
This way, as one batch of cilantro begins to bolt, you’ll have another set of young plants ready to harvest.
Tip 3: Mulching
Mulching around your cilantro plants can help retain soil moisture, keep the roots cool, and reduce weed growth. Organic mulches like straw, grass clippings, or compost are excellent choices for maintaining a healthy growing environment.
FAQs
