Cilantro can grow outside and it actually thrives when you plant it in the right conditions.
If you’ve ever asked yourself “can cilantro grow outside?” the short answer is a big yes.
This wonderful herb loves cool weather and will happily grow outdoors as long as you give it what it needs.
In this post, we’ll cover why cilantro grows so well outside, how to care for it properly, and the best tips for getting a healthy harvest.
Let’s dig in.
Why Cilantro Grows So Well Outside
Cilantro can grow outside, and here’s why it’s such a natural fit for outdoor gardening.
1. Cilantro Loves Cool Outdoor Temperatures
One of the main reasons cilantro grows so well outside is because it thrives in cool weather.
Unlike basil or tomatoes that crave intense heat, cilantro prefers temperatures between 50°F and 85°F.
When you plant cilantro outside in spring or fall, it gets the exact conditions it needs to flourish.
That’s why so many gardeners find that cilantro grows better outdoors than indoors.
2. Natural Sunlight Helps Cilantro Thrive
Cilantro can grow outside because it gets plenty of natural sunlight when planted in the ground or in containers.
This herb does best with about 4 to 6 hours of direct sun each day.
If you live in a hot climate, a spot with morning sun and afternoon shade is ideal for cilantro growing outside.
Too much harsh afternoon sun can make cilantro bolt faster, so a little shade helps.
3. Cilantro Has Room to Spread Its Roots
When cilantro grows outside, its roots have space to stretch and develop fully.
Cilantro has a taproot, which means it doesn’t like being transplanted or crowded.
Planting cilantro outside gives those roots the room they need to grow strong and healthy.
Good drainage in outdoor soil also helps prevent root rot, keeping your cilantro growing strong.
How to Grow Cilantro Outside Successfully
Getting cilantro to grow outside isn’t hard, but a few simple steps make a big difference.
1. Choose the Right Spot
Pick a spot where cilantro can grow outside with partial shade, especially in warmer zones.
The soil should drain well and be rich in organic matter.
Mixing in some compost before planting gives cilantro a great start.
2. Plant Cilantro Seeds Directly Outside
Since cilantro doesn’t transplant well, sow the seeds directly where you want them to grow.
Plant seeds about a quarter inch deep and space them a few inches apart.
You can also succession plant every 2 to 3 weeks so you always have fresh cilantro growing outside.
3. Water Consistently
Cilantro growing outside needs regular watering to stay happy.
Keep the soil evenly moist but never soggy.
A layer of mulch helps retain moisture and keeps the roots cool.
4. Watch for Bolting
When the weather gets hot, cilantro can grow outside too fast and bolt, meaning it goes to seed.
Once cilantro bolts, the leaves turn bitter and the plant stops producing tasty foliage.
To slow bolting, plant cilantro in partial shade and harvest leaves often.
You can also let some cilantro flower and collect the seeds, which are coriander.
Common Problems When Cilantro Grows Outside
Even though cilantro can grow outside with ease, a few issues can pop up.
1. Pests Love Cilantro Too
Aphids and whiteflies are common pests when cilantro grows outside.
A strong spray of water or insecticidal soap usually handles them.
2. Too Much Heat Causes Bolting
If you plant cilantro outside in the middle of summer, it will likely bolt quickly.
Stick to spring and fall planting for the best results.
3. Overwatering Can Cause Root Rot
Cilantro growing outside in poorly drained soil can suffer from root rot.
Always make sure the soil drains well before you plant cilantro.
So, Can Cilantro Grow Outside?
Cilantro can grow outside and it’s honestly one of the easiest herbs to grow outdoors when you give it the right conditions.
Cool temperatures, partial sun, and consistent watering keep cilantro growing strong all season.
Whether you’re growing cilantro in a garden bed, a raised bed, or a container on your patio, outdoor growing works beautifully.
So go ahead and plant some cilantro outside this season, and enjoy fresh leaves for weeks to come.
