Fresh mint is a true powerhouse of flavor and fragrance. It’s the cooling star of a mojito, the perfect partner to lamb, and the refreshing twist in a glass of iced tea or lemonade. This guide is here to show you exactly how to plant mint in a pot, so you can have an endless supply of this amazing herb right at your fingertips.
Growing mint is incredibly easy, but there is one golden rule you must follow: always, always plant it in a container. Mint is a wonderfully aggressive grower with roots that spread like wildfire.
Planting it in a pot keeps it contained and happy, preventing it from taking over your entire garden. We’ll cover everything you need to know, from picking the perfect pot to keeping your plant lush and productive.
Why You Must Plant Mint in a Pot
We can’t stress this enough. Mint is a member of a plant family known for its ambition. It grows via runners, which are horizontal stems that shoot out just under or over the surface of the soil. These runners can travel far and wide, sending up new mint plants everywhere they go.
What starts as a small, polite patch in your garden can quickly become a full-blown mint lawn, choking out other plants. Planting it in a pot completely contains these runners, keeping the plant under your control while still giving you a bountiful harvest. It’s the responsible and smart way to grow this wonderful herb.
Choosing Your Minty Companions
Before you plant, you get to choose what kind of mint you want to grow. You might be surprised at how many options there are beyond the standard varieties.
Popular Mint Varieties for Pots:
- Spearmint (Mentha spicata): This is the classic mint you often find in grocery stores. It has bright green, pointed leaves and a sweet, mild flavor that’s perfect for drinks, salads, and jellies.
- Peppermint (Mentha piperita): This one has a much stronger, bolder flavor with a high concentration of menthol. It has darker green leaves and is the flavor you associate with candy canes and peppermint tea.
- Chocolate Mint (Mentha piperita ‘Chocolate’): A fascinating variety that really does have subtle notes of chocolate in its aroma and taste. It’s fantastic with desserts or in hot cocoa.
- Mojito Mint (Mentha x villosa): This is the authentic mint variety used to make the famous mojito cocktail in Cuba. It has a milder, less overpowering flavor than other mints, which allows the lime and rum to shine.
- Apple Mint (Mentha suaveolens): This variety has fuzzy, light green leaves and a delicate, fruity flavor that is less intense than spearmint. It’s lovely in fruit salads and iced teas.

The Perfect Pot: Your Mint’s New Home
Choosing the right container is a key step in setting your mint up for success.
Size is Important
Mint has a vigorous root system and it grows fast, so give it some room to spread out.
- Starting Out: A pot that is at least 10 to 12 inches in diameter and about the same depth is a great starting point for a single mint plant.
- Room to Grow: If you want a really big, lush plant, a 14-inch pot or larger (around 5 gallons) is even better. A wider pot is often better than a deeper one, as it gives the runners more surface area to explore.
Material Considerations
- Glazed Ceramic or Plastic: These pots are great choices for mint because they are non-porous and do a good job of retaining moisture. Since mint likes consistently moist soil, these materials mean you’ll have to water a little less often.
- Terracotta: While beautiful, unglazed terracotta pots are porous and dry out very quickly. If you use terracotta, you’ll need to be extra diligent about checking the soil moisture, especially on hot, sunny days.
- Self-Watering Pots: These can be a fantastic, almost foolproof option for mint. They have a built-in reservoir that provides a steady supply of moisture to the roots, keeping the plant perfectly hydrated.
The Most Important Rule
No matter what pot you choose, it must have drainage holes at the bottom. Mint likes moist soil, but it hates soggy, waterlogged soil. Good drainage is essential to prevent root rot.
How to Plant Mint in a Pot: The Step-by-Step Method
You have your plant and your pot. It’s time to get them together! This process is simple and straightforward.
Your Planting Toolkit
- A mint plant (from a nursery or a cutting)
- A pot with drainage holes (at least 10-12 inches wide)
- High-quality potting mix
- A trowel
- Gardening gloves
- Watering can
Step 1: Prepare the Soil
The right soil is crucial. Do not use soil from your garden. It’s too heavy, compacts easily, and can bring pests and weeds along with it.
- Choose a Potting Mix: Use a good quality, all-purpose potting mix designed for containers. These mixes are lightweight and formulated for good drainage and aeration.
- Add a Boost: Mint isn’t a heavy feeder, but it appreciates a little richness in its soil. Mixing a handful of compost into your potting mix is a great way to add some gentle, slow-release nutrients.

Step 2: Prepare the Pot
- If you’re worried about soil washing out of the drainage holes, you can place a single coffee filter or a piece of screen mesh over them. Avoid the old myth of adding a layer of rocks, as this actually hinders drainage.
- Fill your pot about two-thirds full with your prepared potting mix.
Step 3: Planting the Mint
- Carefully remove your mint plant from its nursery container. If it’s a bit stuck, gently squeeze the sides of the pot to loosen it.
- Look at the roots. If they are tightly circling the bottom, use your fingers to gently loosen them up. This helps them spread out into their new home.
- Place the plant in the center of the pot. The top of its root ball should sit about 1 to 2 inches below the rim of the pot. This space at the top prevents water and soil from spilling out when you water.
- Add more potting mix around the plant, filling in all the gaps. Gently firm the soil down with your hands to get rid of any large air pockets.
Step 4: Water It Well
- The first watering is very important. Give your newly potted mint a deep and thorough drink.
- Water until you see it flowing freely from the drainage holes. This helps to settle the soil around the roots and minimizes transplant shock.
- Place your beautiful new mint plant in its designated spot and get ready to enjoy it!
Caring for Your Thriving Mint Plant
Mint is famously low-maintenance, but a little bit of care will keep it lush, healthy, and incredibly productive.
Light Requirements
- Mint is quite adaptable when it comes to light. It grows best with morning sun and some afternoon shade, especially in very hot climates where the intense afternoon sun can scorch its leaves.
- It can tolerate full sun, but you will need to water it much more frequently. It can also grow in partial shade, but the growth might be less vigorous and the flavor less intense. An east-facing location is often ideal.
Watering Wisdom
- Mint likes its soil to be consistently moist but not waterlogged. It does not like to dry out completely.
- The best method is to check the soil every couple of days. Stick your finger about an inch into the soil. If it feels dry, it’s time to water.
- When you water, water deeply until it runs out the bottom, then let it drain. Don’t let it sit in a saucer of water.
The Secret to a Bushy Plant: Harvesting!
This is the best part! The more you harvest your mint, the better it will grow.
- Harvest Often: Regular trimming is the key to preventing your mint from getting tall and “leggy” with sparse leaves. Cutting it back encourages the plant to branch out from the sides, creating a much fuller, bushier plant.
- How to Harvest: Use clean scissors or just your fingers to snip off stems. You can take a few sprigs as needed, or give the whole plant a haircut.
- The One-Third Rule: A good guideline is to never harvest more than one-third of the entire plant at one time. This ensures it has plenty of leaves left to photosynthesize and recover quickly.
- Pinch the Flowers: If you see flower buds forming, pinch them off. Letting the plant flower can cause the leaves to become bitter and will signal the plant to slow down its leaf production.
Dealing with Common Mint Issues
Even a tough plant like mint can run into a few problems. Here’s how to handle them.
- Pests: Mint is naturally pest-repellent, but sometimes aphids or spider mites can appear, especially on stressed plants. A strong spray of water from a hose can often knock them off. For a more stubborn infestation, use an insecticidal soap spray.
- Rust: This is a fungal disease that appears as small, orange-brown dusty spots on the undersides of the leaves. It’s often caused by overcrowding and poor air circulation.
- Solution: Prune your plant to improve airflow. Water the soil directly, not the leaves. Remove and dispose of any heavily infected leaves.
- Leggy Growth: If your plant is tall and spindly with few leaves, it’s likely not getting enough light and/or not being harvested enough. Move it to a sunnier spot and give it a good trim.
Keeping Your Mint Going for Years
After a year or two, you might notice your potted mint plant isn’t as vigorous as it used to be. This is often because it has become root-bound and has used up all the nutrients in the soil.
You have two easy options:
- Repot into a Bigger Pot: Move the entire plant into a pot that is a few inches larger in diameter, using fresh potting mix.
- Divide and Conquer: This is a great way to get free plants!
- Take the plant out of its pot. You will see a dense mass of roots.
- Use a sharp knife or spade to cut the entire root ball into two, three, or even four sections.
- Replant one section back into the original pot with fresh soil, and plant the other sections in new pots to keep for yourself or give to friends!
