Do you love adding a burst of fresh flavor to your dishes? Whether it’s guacamole, curry, or a zesty salad, cilantro brings brightness to any plate. And the good news? You can grow it right at home—even if all you have is a sunny windowsill.
If you’ve never grown herbs before, don’t worry—growing cilantro from seed is one of the easiest and most rewarding ways to get started with gardening. In this guide, we’ll walk you through everything you need to know to grow your own lush, leafy cilantro from seed to harvest.
Why Grow Cilantro at Home?
Cilantro (Coriandrum sativum) is a cool-season herb known for its unique citrusy flavor. Not only do the leaves (cilantro) make a tasty addition to recipes, but the seeds (coriander) are also a valuable spice in global cuisine.
Here’s why you should give it a go:
- Fast-growing: You’ll have harvest-ready leaves in as little as 3–4 weeks.
- Dual-purpose: Use both the leaves and seeds.
- Compact and easy: Perfect for containers, windowsills, and small garden beds.
When to Plant Cilantro Seeds
Cilantro is a cool-season herb, so it prefers temperatures between 50–75°F (10–24°C). Too much heat, and it will bolt (go to seed) quickly.
- Spring Planting: Sow seeds 2 weeks before the last expected frost.
- Fall Planting: Start seeds in late summer to early fall in most regions.
- In hot climates, you can grow cilantro through the winter.
For continuous harvests, sow new seeds every 2–3 weeks.
What You Need
Here’s what you’ll need to grow cilantro from seed successfully:
- Cilantro seeds (organic or heirloom recommended)
- Pots (at least 8 inches deep) or a garden bed
- Well-draining soil, ideally rich in organic matter
- Watering can or spray bottle
- Sunny location (at least 4–6 hours of sunlight daily)
Step-by-Step: How to Grow Cilantro from Seed
1. Prepare Your Seeds
Cilantro seeds are actually two seeds in one husk. For faster germination:
- Lightly crush the seed husks using a rolling pin.
- Soak the seeds in water for 12–24 hours to soften them.
This step is optional but helpful for boosting sprouting speed.
2. Get the Soil Ready
Cilantro loves loose, well-drained soil that’s rich in organic compost. If planting in containers, choose high-quality potting mix.
Soil pH: 6.2 to 6.8 (slightly acidic to neutral)
If growing in a raised bed or container, ensure there are drainage holes to prevent root rot.
3. Sow the Seeds
- Sow seeds ¼ inch deep.
- Space them 1–2 inches apart in rows.
- Rows should be 6–8 inches apart.
For container gardening, scatter seeds lightly across the surface and cover gently with soil.
4. Water and Wait
- Keep the soil evenly moist, but never soggy.
- Water gently with a spray bottle or watering can.
- Seeds germinate in 7 to 14 days.
Place containers in a sunny spot or use a grow light indoors if natural light is limited.
5. Thin and Maintain
Once seedlings are a few inches tall:
- Thin them to 4–6 inches apart for healthy growth.
- Water regularly to keep soil moist (not dry or soaked).
- Mulch lightly to keep roots cool in warmer weather.
How to Harvest Cilantro
- Begin harvesting when plants are 6–8 inches tall.
- Use clean scissors to cut outer leaves at the base.
- Always leave the inner leaves so the plant continues growing.
- For best flavor, harvest in the morning before the sun hits the leaves.
If you want coriander seeds, let the plant flower and go to seed, then collect the dried seed heads.
Common Mistakes to Avoid
| Mistake | Solution |
|---|---|
| Planting in hot weather | Stick to spring and fall for best results. |
| Letting soil dry out | Keep the soil consistently moist, especially during germination. |
| Overcrowding seedlings | Thin plants to allow airflow and prevent disease. |
| Not harvesting often enough | Regular harvesting prevents bolting and promotes new growth. |
Growing Cilantro Indoors
Yes, you can absolutely grow cilantro indoors.
- Use a sunny windowsill or install LED grow lights.
- Ensure good air circulation.
- Rotate pots occasionally so all sides get light.
Pro Tip: Successive Sowing
Because cilantro grows fast and bolts early, plant a new batch every 2–3 weeks to enjoy a steady harvest throughout the season.
