Mint pot size at a glance
| Container | Size | Best for |
|---|---|---|
| Minimum pot | 8 in wide, 8 in deep (20 x 20 cm) | One mint plant, kept trimmed |
| Ideal pot | 10-12 in wide, 8 in deep (25-30 x 20 cm) | One mint plant, long term |
| Shared planter | Not recommended | Mint crowds out neighbours; keep it separate |
Mint is the one herb where the most important pot rule is not the size but the principle: give it its own container. Mint spreads by underground runners and will crowd out anything it shares space with. As a quick answer: plant one mint in a pot about 8 to 12 inches (20 to 30 cm) wide and 8 inches (20 cm) deep, on its own. For how mint compares to other herbs, this page sits alongside the main herb pot size chart.
Why mint needs its own pot
Mint grows vigorously and sends out runners that root wherever they touch soil. In a shared planter or garden bed, it quickly overwhelms slower herbs like parsley or thyme. A dedicated pot keeps it productive without letting it take over, which is far easier than trying to rein it in later.
The right size
- One plant: a pot 8 to 12 inches wide and about 8 inches deep gives mint plenty of room.
- Width over depth: mint spreads sideways, so a wide pot suits it better than a tall, narrow one.
- Material: plastic or glazed pots hold moisture well, which mint appreciates more than the fast-drying terracotta that suits Mediterranean herbs. Best containers for herbs compares the options.
Watering and upkeep
Mint likes more consistent moisture than drought-tolerant herbs, so a slightly larger pot that does not dry out within hours is helpful. Keep the soil lightly moist, not soggy; the rhythm is covered in how often to water mint. Regular trimming keeps it bushy rather than leggy, as explained in how to prune basil, mint, parsley, and chives.
When to repot or divide mint
Mint fills a pot fast. When roots circle the inside, growth slows, or runners climb over the rim, it is time to divide it or move up a size. Lift it, split the clump, and replant the healthiest section, following how to repot herbs without slowing growth.

Common questions
What size pot does mint need?
One mint plant does well in a pot about 8 to 12 inches (20 to 30 cm) wide and 8 inches (20 cm) deep. Mint spreads fast, so give it room and keep it in its own container.
Can mint share a pot with other herbs?
It is usually a bad idea. Mint sends out runners and will crowd out neighbours within a season. If you want mint near other herbs, plant it in its own pot beside them.
Does mint need a deep or wide pot?
Wide is more important than deep, because mint spreads sideways by runners. A wide pot around 8 inches deep gives it room while keeping the roots contained.
How do I stop mint taking over?
Grow it in a dedicated pot rather than a shared bed or planter, and trim it regularly. A standalone container is the simplest way to enjoy mint without it spreading everywhere.
