Let me get straight to the point: mint container growing is the smartest way to enjoy this incredible herb without letting it take over your entire garden. I learned this lesson the hard way — I planted a single spearmint start in my raised bed a few years back, and within one season, it had traveled three feet in every direction, popping up between my tomato plants like an uninvited guest. Pulling it out was a nightmare because every tiny root fragment left behind turned into a new plant. That's when I switched to potted mint plants, and I can tell you, it's a game-changer. When you grow mint in containers, you keep that aggressive growth contained, you can move the pot around to catch the best sunlight, and you can bring it indoors before frost hits. Plus, having mint in pots right by your kitchen door means you can snip fresh leaves whenever you need them — for teas, cocktails, or salads. Trust me, if you've ever struggled with mint taking over your garden, container growing is the perfect solution. Just make sure you use a pot that's at least 12 inches wide with a drainage hole, and you're on your way to a happy, well-behaved mint plant that won't bully your other herbs.

Caring for Container-Grown Mint
Why Grow Mint in Pots Instead of the Ground
Mint is a bully in the garden — plain and simple. It sends out runners underground and takes over beds faster than you'd expect. That's why mint container growing makes so much sense for most home gardeners.
I learned this the hard way a few years back when I planted a single spearmint start in my raised bed. Within one season, it had traveled three feet in every direction and started popping up between my tomato plants. Pulling it out was a nightmare — every tiny root fragment left behind turned into a new plant. That's exactly when I switched to potted mint plants and never looked back. When you grow mint in containers, you keep that aggressive growth contained. You can move the pot around to catch the best sunlight, bring it indoors before frost hits, and place it right by your kitchen door for easy snipping. Plus, mint in pots looks great on a patio or balcony — it's a two-for-one deal: useful herb and attractive foliage plant. The key is using a container at least 12 inches wide with a drainage hole. Anything smaller and you'll be watering constantly during summer heat.
Getting the Soil and Pot Setup Right
Use quality potting mix — not garden soil. Garden soil compacts in containers and suffocates mint roots fast. A good potting mix drains well while holding enough moisture for healthy growth.
When I set up my first batch of container grown mint, I made the mistake of using cheap soil from a big box store. It turned into concrete after two weeks of watering. Now I stick with a premium organic potting mix and mix in a handful of perlite for extra drainage. Here's a quick comparison of what works and what doesn't:
| Potting Mix Type | Drainage Rating | Best For Mint? | Why |
|---|---|---|---|
| Premium organic potting mix | Excellent | Yes | Holds moisture without getting soggy |
| Cheap all-purpose mix | Poor to fair | Not recommended | Compacts easily, leads to root rot |
| Garden soil + compost blend | Poor | No | Too heavy for containers, suffocates roots |
| Coconut coir + perlite mix | Excellent | Yes | Lightweight, great aeration, retains moisture well |
I've tested all four options over the past few years, and the difference is dramatic. Plants in cheap mix looked sad and yellow within a month, while the ones in premium mix stayed lush and dark green all season. Growing mint in containers starts with the soil — don't cut corners here.

Watering and Sunlight for Potted Mint Plants
Check the top inch of soil daily during warm weather. If it feels dry, it's time to water your mint in pots. Mint can handle a little drought but not long dry spells — the leaves wilt fast.
I keep my potted mint plants on the east side of my house where they get about six hours of morning sun and afternoon shade. That sweet spot works perfectly — full sun all day can scorch the leaves in hot climates, while too much shade makes the stems leggy and sparse. Here's what I've noticed after growing mint in containers for four seasons: plants that get at least six hours of direct sunlight produce way more essential oils, which means stronger flavor and better aroma. If you're growing indoors, put the pot in a south-facing window or under a grow light for 12 to 14 hours a day. One tip I swear by — group several pots together on a tray with pebbles and water. The evaporating water boosts humidity around the plants, and mint absolutely loves that. Just make sure the pot itself isn't sitting in water, or you'll invite root rot to the party.
Choosing the Best Mint Varieties for Container Growing
Popular Mint Cultivars That Thrive in Pots
Not all mint behaves the same way in containers. Some varieties stay compact and bushy, while others want to run even in a pot. Choose wisely based on what you plan to use the mint for.
I've grown about eight different mint varieties in containers over the years, and a few stand out as top performers. Spearmint is the classic choice — it's vigorous but manageable in a 12-inch pot, and its flavor works in teas, salads, and cocktails. Peppermint is more upright and spreads a bit slower, making it a great candidate for mint container growing if you want a neat, tidy plant. Chocolate mint has become my personal favorite — it smells like York Peppermint Patties and stays compact in containers. Apple mint and pineapple mint are also excellent choices for pots because they have fuzzy, attractive leaves and a milder flavor that works well in fruit salads and drinks. Avoid pennyroyal mint if you have pets — it's toxic to dogs and cats. And stay away from Mentha canadensis (American wild mint) unless you want a plant that will try to escape even a 20-inch container. I learned that one the hard way.
What to Look for When Buying Starter Plants
Buy from a nursery that specializes in herbs if you can. A healthy mint start should have bright green leaves and firm stems — no yellowing or drooping. Avoid plants that look rootbound in their nursery pots.
Here's a question you might be asking yourself: Should I start mint from seed or buy transplants for mint container growing? I'll tell you straight up — buy transplants. Mint seeds are tiny and germinate unevenly. I tried starting mint from seed twice and ended up with maybe 30% germination both times. The seedlings that did pop up grew so slowly that I didn't get a decent harvest for almost three months. Transplants give you a three- to four-week head start, and you know exactly what variety you're getting — seed packets can be mislabeled sometimes. When you pick out a plant at the nursery, look for one that's bushy with multiple stems coming from the base. Avoid tall, leggy plants with just one or two stems — those were grown too close together and will struggle to fill out in your pot. I also gently tip the plant out of its nursery pot to check the roots. If I see roots circling the bottom, that plant is rootbound and needs to be freed before going into its permanent container. I usually loosen those circling roots with my fingers or make a few vertical cuts with a knife before planting.
Common Mistakes People Make with Potted Mint

Watering and Sunlight for Potted Mint Plants
One mint plant per 12-inch pot is plenty. Cramming multiple plants into one container leads to competition for water and nutrients. The leaves turn yellow, and growth stalls.
I see this mistake all the time — people buy three or four mint starts and plant them all in one medium-sized pot thinking they'll get a bigger harvest faster. It backfires every single time. Mint roots are aggressive even in containers, and when they compete for limited space, the plants stress out. Potted mint plants need room to spread their roots, and a single well-grown plant in a 12-inch pot will produce more leaves than three cramped plants in the same container. Drainage is another huge issue — if your pot doesn't have holes in the bottom, you're basically creating a swamp for the roots. Mint likes consistent moisture but absolutely cannot sit in waterlogged soil. I once used a decorative ceramic pot without drilling holes, and my mint died within three weeks from root rot. The leaves turned brown and mushy, and the whole thing smelled like a wet basement. Always drill drainage holes or use a plastic nursery pot inside a decorative cache pot — that way you can lift the inner pot out to drain after watering.
Overfertilizing and Letting Mint Bloom
Too much fertilizer ruins the flavor of mint in pots. The leaves grow big and lush but lose that sharp, pungent kick you want. I use a half-strength balanced liquid fertilizer once a month during the growing season — that's it.
I made the overfertilizing mistake my first year. I thought "more food = more growth = more mint," so I fed my plants every week with full-strength fertilizer. The plants exploded with growth — huge leaves, thick stems, dark green everywhere. But when I picked a handful for tea, the flavor was flat and almost grassy. That's when I learned that excess nitrogen dilutes the essential oils that give mint its characteristic taste and smell. Now I use a slow-release organic fertilizer mixed into the soil at planting time, and I supplement with a diluted liquid seaweed feed once a month if the plants look like they need a boost. Blooms are another flavor killer — when container grown mint flowers, the plant puts all its energy into seed production instead of leaf growth. The leaves become smaller, tougher, and less flavorful. I pinch off flower buds as soon as I spot them, sometimes checking my pots every few days during peak growing season. This keeps the plant focused on producing tender, aromatic leaves all the way through fall.
Harvesting and Pruning Potted Mint Plants
How to Harvest Without Damaging the Plant
Always cut stems above a leaf node — that's where the plant will branch out. Never strip all the leaves from one stem because that stem will die back and leave a bare spot in your pot.
When I harvest my mint in pots, I follow a simple rule: take no more than one-third of the plant at a time. This ensures the plant has enough leaf surface to keep photosynthesizing and regrowing. I use sharp kitchen shears for clean cuts — tearing stems with your fingers can damage the plant and invite disease. Start harvesting from the top down, cutting each stem back to just above a pair of leaves. Within a week or two, you'll see two new stems emerging from each cut point. This is the secret to keeping potted mint plants bushy and productive — regular harvesting actually encourages more growth. If you let the plant grow unchecked, the stems get tall and floppy, and the lower leaves turn yellow and drop off. I harvest my outdoor containers about once a week during summer, and by the end of the season, I've collected enough mint to fill several freezer bags for winter use. For indoor mint container growing, I harvest a bit less frequently — about every two weeks — since growth slows down with less intense light.

Watering and Sunlight for Potted Mint Plants
Pinch the tips of each stem when the plant reaches about six inches tall. This forces the plant to branch out instead of growing straight up. Do this every few weeks for a full, dense plant.
I compare pruning mint in pots to giving the plant a haircut — you want to shape it, not scalp it. Here's my routine: every time I harvest, I also take a few minutes to trim any stems that look leggy or are growing outward past the pot rim. If the plant starts looking sparse in the center, I cut the tallest stems back by half to encourage lower branching. I've found that a midsummer hard prune works wonders — around July, I cut the entire plant back to about two inches above the soil. This sounds drastic, but within three weeks, the plant comes back fuller and more vigorous than before. The new growth is tender, bright green, and packed with flavor. Don't be afraid to cut your container grown mint back hard — mint is incredibly resilient and bounces back from aggressive pruning faster than almost any other herb I've grown. I've had plants that I cut back to stubs come roaring back to full size within a month. Just make sure to water well after pruning and give the plant a light feeding to support the regrowth.
Winter Care and Long-Term Maintenance
Protecting Mint in Cold Weather
Mint is hardy in most climates, but mint in pots needs extra protection during winter. The roots in a container freeze faster than roots in the ground. A simple solution is moving the pot to a sheltered spot or indoors.
Here's another question that comes up often: Can I leave my potted mint plants outside all winter without doing anything special? The honest answer is — it depends on your climate. In USDA zones 5 and warmer, mint usually survives winter in containers if you take a few precautions. I live in zone 6, and here's what I do: after the first hard frost kills back the top growth, I cut the stems down to about an inch above the soil. Then I move the pot against the foundation of my house on the south side, where it gets some warmth from the building. I mulch the top of the pot with a thick layer of straw or shredded leaves — about four to six inches deep. This insulates the roots from extreme temperature swings. In colder zones (3 and 4), you're better off moving the pot into an unheated garage or basement for the winter. Water sparingly — maybe once a month — just enough to keep the soil from completely drying out. For indoor mint container growing through winter, bring the pot inside before the first frost and place it in a bright window. Growth will slow down, but you'll still get occasional harvests for teas and cooking.
When to Repot or Divide Container Mint
After a year or two, mint in pots can become rootbound. The plant will look healthy but stop growing, and water will run straight through the pot without soaking in. That's your sign to repot or divide.
I repot my potted mint plants every spring, usually in March or early April before the main growing season kicks in. I lift the plant out of its pot and check the root ball — if I see a solid mass of roots with little soil visible, it's time. Here's my step-by-step process: I gently tease apart the root ball and divide it into two or three sections, each with healthy roots and stems. I plant each division in its own container with fresh potting mix, water well, and place them in a bright spot. This gives me free new plants every year, and the original plant stays vigorous instead of declining from being rootbound. I've been maintaining the same spearmint plant for five years by dividing it annually — I now have about a dozen pots spread across my patio and windowsills. Mint container growing works beautifully as a long-term system if you stay on top of dividing and repotting. One warning though: don't put old potting mix back into the pot — it's depleted of nutrients and can harbor disease organisms. Always use fresh mix when repotting, and you'll keep your mint thriving for years.
Using Your Homegrown Container Mint
Fresh Mint in the Kitchen
Fresh mint from your own mint in pots tastes completely different from store-bought. The flavor is brighter, more intense, and has that fresh-picked aroma that fades within hours of harvesting. Use it within a day for the best results.
I use my container grown mint in more ways than I ever expected. Mojitos are the obvious choice — muddle five or six leaves with lime and sugar for a drink that beats anything from a bar. But mint also shines in savory dishes. I chop mint finely and mix it into yogurt with garlic for a sauce that goes perfectly with lamb or roasted vegetables. Toss a handful of leaves into a salad with cucumber and feta cheese — the freshness cuts through the richness of the cheese. Tea is my go-to daily use — I steep about ten leaves in hot water for five minutes, strain, and add a teaspoon of honey. It's soothing, caffeine-free, and helps digestion after meals. For longer storage, I chop mint leaves and freeze them in ice cube trays with a little water. Those mint cubes are perfect for adding to lemonade or cocktails all winter long. Growing mint in containers means you always have fresh herbs within arm's reach — I honestly use more mint now than I ever did when I bought it from the store.
Preserving Mint for Off-Season Use
Drying mint is the simplest preservation method. Cut stems just before the plant flowers for the highest oil content. Tie them in small bundles and hang them upside down in a dark, dry place for about two weeks.
I dry about half of my potted mint plants harvest every year, and the dried leaves stay flavorful for up to a year if stored properly. Here's what I've found works best: harvest on a dry morning after the dew has evaporated but before the heat of the day. The essential oil concentration peaks at this time. Rinse the stems gently and pat them dry with a towel — moisture on the leaves can cause mold during drying. Bundle four to six stems together with a rubber band and hang them in a closet or pantry. I avoid using a dehydrator because the heat can drive off volatile oils — air drying at room temperature preserves more of the mint's character. Once the leaves crumble easily between your fingers, strip them off the stems and store them in an airtight jar in a dark cabinet. Label the jar with the variety and date because different mints look similar when dried. For an even more intense flavor, you can make mint-infused vinegar or sugar. Pack fresh mint leaves into a jar, cover with white wine vinegar or granulated sugar, and let it sit for two weeks. Strain out the leaves, and you have a flavored ingredient that adds minty notes to dressings or baked goods all year round.
Pest and Disease Prevention for Container Mint
Common Pests That Bother Potted Mint
Mint is relatively pest-resistant, but a few critters still cause trouble. Aphids, spider mites, and mint flea beetles are the most common offenders. Check the undersides of leaves regularly during warm weather.
I've dealt with aphids on my mint in pots a few times, and the fix is usually simple. A strong blast of water from the hose knocks most of them off. For stubborn infestations, I mix a teaspoon of mild dish soap with a quart of water and spray the plant thoroughly, focusing on the undersides of leaves where aphids hide. Spider mites are trickier — they thrive in hot, dry conditions and show up as fine webbing between stems and leaves. Increasing humidity around your potted mint plants by misting them daily or using a pebble tray often prevents spider mites from taking hold. Mint flea beetles chew small round holes in the leaves, but they rarely cause serious damage — I usually just ignore them unless the holes become extensive. The best pest prevention for mint container growing is keeping the plants healthy. Stressed plants attract pests, so proper watering, adequate light, and good air circulation go a long way. I also inspect my plants every time I water — catching a problem early makes treatment much easier than waiting until the infestation is out of control.
Diseases to Watch For in Container Mint
Root rot is the number one disease risk for mint in pots. It happens when the soil stays too wet for too long — the roots turn brown and mushy, and the leaves wilt despite wet soil. Good drainage is your best defense.
I lost two mint plants to root rot before I figured out what I was doing wrong. I was using saucers under the pots and letting the water sit there after watering. The soil stayed soggy, and the roots slowly suffocated. Now I empty the saucer 30 minutes after watering — any water that hasn't been absorbed gets dumped. Powdery mildew is another issue, especially for indoor potted mint plants with poor air circulation. It shows up as a white powdery coating on the leaves. I treat it by improving airflow — moving the plant to a spot with better ventilation and spacing my pots apart. If the mildew persists, I mix one part milk with nine parts water and spray the leaves once a week. The milk proteins create an environment that inhibits mildew growth without harming the plant. Never compost diseased plant material — throw it in the trash to prevent spreading pathogens to your other plants. With proper care, diseases are rare in mint container growing, but catching them early makes all the difference.

But mint also shines in savory dishes. I chop mint finely and mix it into yogurt with garlic for a sauce that goes perfectly with lamb or roasted vegetables. Toss a handful of leaves into a salad with cucumber and feta cheese — the freshness cuts through the richness of the cheese. Tea is my go-to daily use — I steep about ten leaves in hot water for five minutes, strain, and add a teaspoon of honey. It's soothing, caffeine-free, and helps digestion after meals. For longer storage, I chop mint leaves and freeze them in ice cube trays with a little water. Those mint cubes are perfect for adding to lemonade or cocktails all winter long. Growing mint in containers means you always have fresh herbs within arm's reach — I honestly use more mint now than I ever did when I bought it from the store.
Preserving Mint for Off-Season Use
Drying mint is the simplest preservation method. Cut stems just before the plant flowers for the highest oil content. Tie them in small bundles and hang them upside down in a dark, dry place for about two weeks.
I dry about half of my potted mint plants harvest every year, and the dried leaves stay flavorful for up to a year if stored properly. Here's what I've found works best: harvest on a dry morning after the dew has evaporated but before the heat of the day. The essential oil concentration peaks at this time. Rinse the stems gently and pat them dry with a towel — moisture on the leaves can cause mold during drying. Bundle four to six stems together with a rubber band and hang them in a closet or pantry. I avoid using a dehydrator because the heat can drive off volatile oils — air drying at room temperature preserves more of the mint's character. Once the leaves crumble easily between your fingers, strip them off the stems and store them in an airtight jar in a dark cabinet. Label the jar with the variety and date because different mints look similar when dried. For an even more intense flavor, you can make mint-infused vinegar or sugar. Pack fresh mint leaves into a jar, cover with white wine vinegar or granulated sugar, and let it sit for two weeks. Strain out the leaves, and you have a flavored ingredient that adds minty notes to dressings or baked goods all year round.
Pest and Disease Prevention for Container Mint
Common Pests That Bother Potted Mint
Mint is relatively pest-resistant, but a few critters still cause trouble. Aphids, spider mites, and mint flea beetles are the most common offenders. Check the undersides of leaves regularly during warm weather.
I've dealt with aphids on my mint in pots a few times, and the fix is usually simple. A strong blast of water from the hose knocks most of them off. For stubborn infestations, I mix a teaspoon of mild dish soap with a quart of water and spray the plant thoroughly, focusing on the undersides of leaves where aphids hide. Spider mites are trickier — they thrive in hot, dry conditions and show up as fine webbing between stems and leaves. Increasing humidity around your potted mint plants by misting them daily or using a pebble tray often prevents spider mites from taking hold. Mint flea beetles chew small round holes in the leaves, but they rarely cause serious damage — I usually just ignore them unless the holes become extensive. The best pest prevention for mint container growing is keeping the plants healthy. Stressed plants attract pests, so proper watering, adequate light, and good air circulation go a long way. I also inspect my plants every time I water — catching a problem early makes treatment much easier than waiting until the infestation is out of control.
Diseases to Watch For in Container Mint
Root rot is the number one disease risk for mint in pots. It happens when the soil stays too wet for too long — the roots turn brown and mushy, and the leaves wilt despite wet soil. Good drainage is your best defense.
I lost two mint plants to root rot before I figured out what I was doing wrong. I was using saucers under the pots and letting the water sit there after watering. The soil stayed soggy, and the roots slowly suffocated. Now I empty the saucer 30 minutes after watering — any water that hasn't been absorbed gets dumped. Powdery mildew is another issue, especially for indoor potted mint plants with poor air circulation. It shows up as a white powdery coating on the leaves. I treat it by improving airflow — moving the plant to a spot with better ventilation and spacing my pots apart. If the mildew persists, I mix one part milk with nine parts water and spray the leaves once a week. The milk proteins create an environment that inhibits mildew growth without harming the plant. Never compost diseased plant material — throw it in the trash to prevent spreading pathogens to your other plants. With proper care, diseases are rare in mint container growing, but catching them early makes all the difference.

FAQs
Q: Why is it better to grow mint in pots instead of the ground?
A: Growing mint in the ground is a recipe for regret — I learned that the hard way. Within one season, a single spearmint start traveled three feet in every direction underground and popped up between my tomato plants. Pulling it out was a nightmare because every tiny root fragment left behind turned into a new plant. That's why we always recommend mint container growing for most home gardeners. When you grow mint in containers, you keep that aggressive root system completely contained. Instead of fighting a takeover, you can focus on enjoying the harvest. Potted mint plants also give you flexibility — you can move the pot around to catch the best sunlight, bring it indoors before frost hits, and place it right by your kitchen door for easy snipping when you're cooking. Plus, mint in pots looks great on a patio or balcony. The key is using a container at least 12 inches wide with a drainage hole. Anything smaller, and you'll be watering constantly during summer heat. Trust me, once you switch to containers, you'll never go back to planting mint in the ground.
Q: What's the best soil and pot setup for potted mint plants?
A: Use quality potting mix — never garden soil. Garden soil compacts in containers and suffocates mint roots fast. I made this mistake my first year using cheap mix from a big box store, and it turned into concrete after two weeks of watering. Now I stick with a premium organic potting mix and mix in a handful of perlite for extra drainage. For container grown mint, the pot needs a drainage hole — no exceptions. I once used a decorative ceramic pot without drilling holes, and my mint died within three weeks from root rot. The leaves turned brown, and the whole thing smelled like a wet basement. One mint plant per 12-inch pot is plenty — cramming multiple plants into one container leads to competition for water and nutrients. I've tested four different potting mix types over the years: premium organic mix works best, cheap all-purpose mix compacts, garden soil is too heavy, and coconut coir with perlite is excellent. The difference is dramatic. Plants in premium mix stay lush and dark green all season, while those in cheap mix look sad and yellow within a month. Don't cut corners on the soil — it's the foundation of successful mint container growing.
Q: How much water and sunlight do mint in pots need?
A: Check the top inch of soil daily during warm weather. If it feels dry, it's time to water your mint in pots. Mint can handle a little drought but not long dry spells — the leaves wilt fast. I keep my potted mint plants on the east side of my house where they get about six hours of morning sun and afternoon shade. That sweet spot works perfectly. Full sun all day can scorch the leaves in hot climates, while too much shade makes the stems leggy and sparse. After growing mint in containers for four seasons, I've noticed that plants getting at least six hours of direct sunlight produce way more essential oils, which means stronger flavor and better aroma. For indoor mint container growing, put the pot in a south-facing window or under a grow light for 12 to 14 hours a day. One tip I swear by — group several pots together on a tray with pebbles and water. The evaporating water boosts humidity around the plants, and mint absolutely loves that. Just make sure the pot itself isn't sitting in water, or you'll invite root rot. I empty the saucer 30 minutes after watering to prevent soggy soil. That simple habit saved my mint from drowning.
Q: How do I prevent common mistakes like overfertilizing or letting mint bloom?
A: Too much fertilizer ruins the flavor of mint in pots. The leaves grow big and lush but lose that sharp, pungent kick you want. I made this mistake my first year by feeding weekly with full-strength fertilizer. The plants exploded with growth, but when I picked leaves for tea, the flavor was flat and almost grassy. Excess nitrogen dilutes the essential oils. Now I use a slow-release organic fertilizer mixed into the soil at planting time, and supplement with a diluted liquid seaweed feed once a month if needed. Blooms are another flavor killer — when container grown mint flowers, the plant puts all its energy into seed production instead of leaf growth. The leaves become smaller, tougher, and less flavorful. I pinch off flower buds as soon as I spot them, sometimes checking my pots every few days during peak growing season. This keeps the plant focused on producing tender, aromatic leaves all the way through fall. Overcrowding is also common — one mint per 12-inch pot is enough. Don't think you'll get a bigger harvest by planting three in one pot. A single well-grown plant produces more leaves than three cramped plants competing for space. Drainage is equally critical — always drill holes or use a nursery pot inside a decorative cache pot.
Q: How do I harvest and prune potted mint plants without damaging them?
A: Always cut stems above a leaf node — that's where the plant will branch out. Never strip all the leaves from one stem because that stem will die back and leave a bare spot in your pot. When I harvest my mint in pots, I follow a simple rule: take no more than one-third of the plant at a time. This ensures enough leaf surface for photosynthesis. I use sharp kitchen shears for clean cuts — tearing stems with your fingers can damage the plant and invite disease. Start harvesting from the top down, cutting each stem back to just above a pair of leaves. Within a week or two, you'll see two new stems emerging from each cut point. Regular harvesting actually encourages more growth. I harvest my outdoor potted mint plants about once a week during summer, and by season's end, I've filled several freezer bags. For indoor mint container growing, I harvest every two weeks since growth slows. I also do a midsummer hard prune — around July, I cut the entire plant back to about two inches above the soil. This sounds drastic, but within three weeks, the plant comes back fuller and more vigorous. Don't be afraid to cut your container grown mint back hard — mint is incredibly resilient. I've had plants that I cut to stubs come roaring back to full size within a month.
