Yes, you can plant cilantro outside, and it actually thrives best when grown outdoors in the right conditions.
Cilantro is a cool-season herb that loves mild temperatures, so planting it outside gives it the natural environment it needs to flourish.
If you’ve been wondering whether you can plant cilantro outside without a greenhouse or fancy setup, the answer is a resounding yes.
In this post, we’ll go over why you can plant cilantro outside, the best conditions for doing so, and a few tips to keep it productive all season.
Let’s dig in.
Why You Can Plant Cilantro Outside
You can plant cilantro outside because this herb is naturally suited to outdoor gardens, and here’s why:
1. Cilantro Is a Cool-Season Crop
Cilantro grows best when temperatures are between 50°F and 85°F.
That’s why you can plant cilantro outside in spring or fall and get the most vigorous growth.
When the weather gets too hot, cilantro tends to bolt, meaning it shoots up a flower stalk and stops producing those tasty leaves.
Planting it outside during the cooler months helps you avoid that problem.
2. Cilantro Needs Plenty of Sunlight
When you plant cilantro outside, it can soak up the sun it craves.
Cilantro does best with at least four to six hours of direct sunlight each day.
In partial shade, it will still grow, but you might get fewer leaves.
That balance of sun and cool air is hard to replicate indoors, which is another reason planting cilantro outside works so well.
3. Outdoor Soil and Drainage Are Ideal
Cilantro hates soggy roots.
When you plant cilantro outside in well-draining soil, you give it the perfect foundation.
A raised bed or a container with drainage holes works great too.
The natural airflow outdoors also helps prevent fungal diseases that can plague indoor herbs.
4. Cilantro Attracts Beneficial Insects
Planting cilantro outside invites bees and other pollinators to your garden.
Even if you’re growing it mainly for leaves, those tiny white flowers that appear when it bolts are a magnet for beneficial bugs.
That’s a nice bonus for the rest of your garden.
When and How to Plant Cilantro Outside
Timing is everything if you want to plant cilantro outside successfully.
1. Plant in Early Spring or Late Summer
The best time to plant cilantro outside is as soon as the soil can be worked in spring.
Cilantro can handle a light frost, so you don’t have to wait for the last frost date.
For a fall crop, plant cilantro outside again in late summer when the heat starts to fade.
2. Sow Seeds Directly
Cilantro doesn’t transplant well because of its long taproot.
That’s why you should plant cilantro outside by sowing seeds directly where they’ll grow.
Scatter the seeds lightly and cover them with about a quarter inch of soil.
Keep the area moist until seedlings appear, usually within seven to ten days.
3. Space Them Properly
When you plant cilantro outside, give each plant about six to eight inches of space.
If you’re growing in containers, you can plant cilantro outside in a pot that’s at least ten inches deep.
Crowded cilantro is more prone to bolting and disease.
4. Water Consistently
Consistent moisture is key after you plant cilantro outside.
Aim for about an inch of water per week, either from rain or your hose.
Mulching around the base helps keep the soil cool and moist.
Tips for Growing Cilantro Outside Successfully
Once you plant cilantro outside, a little care goes a long way.
1. Harvest Often
Frequent harvesting encourages new leaf growth.
Snip the outer stems first, and never take more than a third of the plant at once.
2. Succession Plant
Because cilantro bolts quickly in warm weather, plant cilantro outside every two to three weeks for a continuous supply.
3. Shade in Summer
If you live in a hot climate, plant cilantro outside where it gets afternoon shade.
This extends the harvest window and delays bolting.
4. Let Some Bolt
Letting a few plants flower gives you coriander seeds later.
Those seeds can be used in cooking or saved for the next time you plant cilantro outside.
So, Can You Plant Cilantro Outside?
You can plant cilantro outside, and it’s actually the best way to grow this flavorful herb.
All it needs is cool weather, decent sun, and well-draining soil.
Whether you sow seeds in a garden bed or a patio pot, planting cilantro outside gives you a fresh supply of leaves for salsa, soups, and salads.
Just remember to water consistently and harvest often.
Hope this post has helped you understand why and how you can plant cilantro outside for a thriving crop.
