Growing cilantro in pots offers so many benefits, especially for those with limited garden space. It allows you to control the plant’s environment, ensuring optimal sunlight, water, and drainage for healthy growth.
Containers also make it easier to move cilantro to sunnier or shadier spots as needed. Since cilantro can be sensitive to hot temperatures, growing it in pots gives you the flexibility to bring it indoors during extreme weather.
In addition, growing cilantro in containers can reduce pest issues and allows for a convenient harvest right from your patio, balcony, or windowsill.
How to Grow Cilantro in Pots
Cilantro, also known as coriander or Chinese parsley, is a versatile herb commonly used in a wide range of dishes. It can easily be grown in pots.
This guide will walk you through the entire process of growing cilantro in pots, from selecting the right container to harvesting.
1. Choosing the Right Pot
Cilantro has a deep root system, so it’s essential to choose a pot that is at least 12 inches deep. A wider pot is also beneficial as it allows more space for the plant to spread out. Drainage holes are crucial to prevent water from stagnating and causing root rot.
- Recommended pot size: 12 inches deep and at least 8-10 inches wide.
- Material: Terracotta, plastic, or ceramic pots with good drainage.
2. Selecting Soil for Cilantro
Cilantro prefers well-draining, loamy soil. You can use a high-quality potting mix designed for herbs or vegetables. Avoid heavy clay-based soils, which can retain too much moisture and lead to waterlogging.
- Soil mix: A balanced mix of potting soil, perlite, and compost works well.
- pH level: Cilantro thrives in slightly acidic to neutral soil, with a pH between 6.2 and 6.8.
3. Choosing Cilantro Seeds or Plants
You can grow cilantro either from seeds or by transplanting young cilantro plants.
- Seeds: Cilantro seeds, also called coriander seeds, are easy to plant. Since cilantro has a short lifecycle, growing from seeds is often the best approach.
- Transplants: You can also start with young plants from a nursery, but they may bolt (flower and go to seed) more quickly than those grown from seed.
4. Planting Cilantro Seeds
Cilantro does not transplant well due to its long taproot, so it’s best to sow seeds directly in the pot.
- Step-by-step process:
- Fill the pot with the prepared potting mix, leaving about an inch of space at the top.
- Sprinkle the seeds over the soil surface, aiming for 1 seed per 1 inch. If planting multiple rows in a wide pot, space the rows about 6 inches apart.
- Cover the seeds with a thin layer of soil, about 1/4 inch deep.
- Water gently but thoroughly to ensure even moisture.
5. Watering Cilantro
Cilantro needs consistent moisture, especially in the early stages of growth. However, it’s important not to overwater.
- Watering frequency: Water when the top inch of soil feels dry, keeping the soil evenly moist but not soggy.
- Tips: Use a spray bottle or watering can with a fine spout to avoid disturbing the soil or young seedlings.
6. Sunlight and Temperature
Cilantro thrives in cool weather and grows best in temperatures between 50°F and 70°F (10°C and 21°C). Too much heat can cause the plant to bolt, which means it will flower and go to seed quickly, reducing leaf production.
- Sunlight: Cilantro prefers full sun but can tolerate partial shade, especially in hot climates.
- Position: Place the pot in a location that gets at least 4-6 hours of sunlight daily. If growing indoors, position it near a sunny window.
7. Fertilizing Cilantro
Cilantro doesn’t need heavy feeding. A light application of a balanced, water-soluble fertilizer every 3-4 weeks is sufficient.
- Fertilizer type: Use a 10-10-10 (N-P-K) fertilizer or one specifically formulated for herbs.
- Organic option: If you prefer organic gardening, you can use compost tea or a seaweed-based fertilizer.
8. Managing Pests and Diseases
Cilantro is generally pest-resistant but can sometimes be affected by aphids, spider mites, and fungal diseases like powdery mildew.
- Pest control: Use insecticidal soap or neem oil to treat aphids or mites. Encourage beneficial insects like ladybugs.
- Disease prevention: Ensure good air circulation around the plants, and avoid overhead watering to reduce the risk of fungal infections.
9. Harvesting Cilantro
Cilantro leaves are ready to harvest in about 3-4 weeks after planting when the plant is 4-6 inches tall.
- How to harvest: Cut the outer leaves first, leaving the inner ones to continue growing. Use clean scissors or garden shears to cut stems close to the base.
- Harvest regularly: Regular harvesting encourages more leafy growth and delays bolting.
- When to stop harvesting: Once cilantro begins to bolt, the leaves become bitter, and it’s best to let the plant go to seed if you want coriander seeds.
10. Preventing Bolting
Cilantro tends to bolt in hot weather, which reduces the amount of foliage produced.
- To prevent bolting:
- Provide shade in the afternoon if you live in a hot climate.
- Keep the soil consistently moist.
- Harvest frequently to keep the plant focused on producing leaves.
11. Growing Cilantro Indoors
If you live in an area with extreme temperatures, you can grow cilantro indoors in pots.
- Lighting: Use grow lights if natural light is insufficient. Cilantro needs about 10-12 hours of light indoors.
- Temperature: Keep the indoor temperature around 65°F to 70°F (18°C to 21°C) for optimal growth.
12. Saving Cilantro Seeds
If your cilantro plants bolt, you can collect the seeds to use as coriander spice or plant them for the next growing season.
- How to save seeds:
- Allow the flowers to dry on the plant.
- Collect the seeds once they turn brown and dry.
- Store the seeds in an airtight container in a cool, dark place.
13. Common Problems with Cilantro
- Yellowing leaves: Often a sign of overwatering or poor drainage.
- Bolting: This is natural in hot weather, but regular harvesting and keeping the plant cool can delay it.
- Slow or uneven germination: Cilantro seeds can take 7-10 days to germinate. Be patient and keep the soil consistently moist.
14. Tips for Success
- Plant cilantro every 2-3 weeks for a continuous harvest.
- Use a saucer under your pot to catch excess water and prevent root rot.
- Consider companion planting cilantro with basil, parsley, or tomatoes to enhance growth and repel pests.
FAQ
Cilantro grows best in loose, well-draining soil. Use a high-quality potting mix rich in organic matter. Adding compost helps provide nutrients.
Water cilantro regularly, keeping the soil evenly moist but not soggy. Check the top inch of soil; if it feels dry, it’s time to water.
Bolting happens when cilantro flowers prematurely due to heat. To prevent this, provide shade during the hottest part of the day, and keep the plant well-watered.
Cilantro usually takes 3-4 weeks to reach harvestable size after planting seeds, and it continues to produce leaves for a few months if properly cared for.
