Cilantro pot size at a glance
| Container | Size | Best for |
|---|---|---|
| Minimum pot | 8 in deep, 6 in wide (20 x 15 cm) | A small cluster, sown directly |
| Ideal pot | 10 in deep, 8 in wide (25 x 20 cm) | Steady leaf harvests |
| Trough | 8-10 in deep, succession sown | Continuous supply through the season |
Cilantro (sold as coriander in much of the world) is a taproot herb, much like its relative parsley, so depth matters more than width and it strongly prefers to be sown where it will grow. As a quick answer: use a pot at least 8 to 10 inches (20 to 25 cm) deep and 6 to 8 inches (15 to 20 cm) wide, and sow seeds directly into it. For how cilantro compares to other herbs, this page sits alongside the main herb pot size chart.
Why cilantro needs a deep pot
Cilantro sends down a central taproot early. A shallow pot cramps that root, which slows the plant and can push it to bolt (flower and go to seed) sooner. A deeper container gives the taproot room and keeps the plant leafy for longer. This is the same reason its relative needs depth, covered in parsley pot size.
Sow directly, do not transplant
Because cilantro resents root disturbance, moving seedlings often triggers bolting. The reliable approach is to sow seeds straight into the final pot and thin them, rather than starting elsewhere and transplanting. A loose, well-draining mix helps the taproot run; see best potting soil for potted herbs.
The right size
- A small cluster: an 8 inch deep pot, 6 inches wide.
- Steady harvests: 10 inches deep and 8 wide.
- Continuous supply: a deep trough, succession sown every few weeks.
Keep it cool and succession sow
Cilantro bolts in heat, so keep the pot evenly moist and out of intense, hot sun, and start a fresh batch every few weeks for a continuous supply. The watering side is covered in how often to water potted herbs.

Common questions
What size pot does cilantro need?
A pot at least 8 to 10 inches (20 to 25 cm) deep and 6 to 8 inches (15 to 20 cm) wide. Cilantro has a taproot, so depth matters most, and it is best sown directly into its final pot.
Does cilantro need a deep pot?
Yes. Like parsley, cilantro sends down a taproot, so a shallow pot stalls it and can trigger early bolting. Aim for at least 8 inches of depth.
Can I transplant cilantro seedlings?
It is risky. Cilantro dislikes root disturbance and often bolts after transplanting, so sowing seeds directly into the final container gives better results.
How do I keep cilantro from bolting?
Use a deep pot, keep it cool and evenly moist, and sow a fresh batch every few weeks. Heat and root stress are the main triggers for bolting.
